6 Ways to Find Free Firewood

Gathering firewood can be an enjoyable and rewarding experience, especially if you can find it for free. Here are six ways to score some free firewood:

1. Look in Your Local Area

Online marketplaces like Craigslist, Facebook Marketplace, and Freecycle are great places to find people who are giving away firewood. You can also post an ad yourself or keep an eye out for print ads in your local grocery store, post office, or community center.

2. Clean up After a Storm

Heavy storms can often bring down branches or even entire trees, providing you with an opportunity to gather free firewood. Be sure to get out there quickly after the storm has passed, as most towns begin their cleanup efforts rather quickly. You can also visit designated drop-off points for tree branches to see if there are any extras you can use.

3. Hit up a Construction Site

Construction sites are another great place to find free firewood. When new homes or businesses are being built, trees often need to be cleared away. You can offer to haul away the debris in exchange for the firewood. Just be sure to get permission from the construction company or individual first.

4. Offer Tree Trimming Services

If you have the expertise and equipment to prune tree limbs or branches, you can offer your services in exchange for firewood. Many people are happy to have their trees trimmed back, especially if they can get free firewood in return. You can also contact local tree trimmers to see if they have any extra wood they are willing to sell or give away.

5. Visit a Sawmill

Sawmills produce lumber from tree logs, but they typically don’t use 100% of the tree. You can ask the sawmill if they have any scraps or extras that you can take away for firewood. Sawmills often have to pay to dispose of this waste wood, so they may be happy to give it to you for free.

6. Use Wooden Pallets for Firewood

Wooden pallets can be a good source of firewood in a pinch. However, it’s important to make sure that the pallets you use are safe to burn. Avoid pallets that have an abundance of nails, screws, or staples. Also, steer clear of pallets that have visible stains or that have been marked with “MB,” which denotes the presence of a dangerous treatment known as methyl bromide. When in doubt, err on the side of caution and only burn pallets deemed “safe” outdoors.

Additional Tips

  • Not all trees are good for firewood. Some burn hotter, others slower, some clean, and some smoky. Oak is generally considered to be the best firewood because it burns long and slow.
  • A cord of wood is a stack of firewood that is 4 by 4 by 8 feet (128 cubic feet). The average price for a cord of wood is $300, but you can find prices between $120 and $900 depending on the wood type, source, and if it is dry or seasoned.
  • You should cover a stack of dry firewood with a tarp to protect it from the elements, but make sure that the sides of the stack remain open to allow for air circulation. This will help prevent mold and rot.

Glaciers: Unlocking Centuries of Climate History Through Ice Cores

by Peter
written by Peter

Glaciers: Frozen Archives of Climate History

Glaciers, massive rivers of ice, are like time capsules, preserving centuries of climate data within their icy layers. Scientists study these layers, known as ice cores, to understand how our planet’s climate has changed over time.

Ice Cores: Unlocking the Past

Ice cores are drilled from glaciers and analyzed to reveal valuable information about past climates. By studying the layers of ice, scientists can determine the amount and type of precipitation, temperature fluctuations, and even volcanic eruptions that have occurred over hundreds or even thousands of years.

Glaciers in the Pacific Northwest

While ice cores have been successfully extracted from glaciers in the Arctic, Antarctica, and Greenland, scientists have long doubted the possibility of obtaining reliable cores from the Pacific Northwest. The region’s warm summers can melt the ice, potentially scrambling the layers and compromising the data.

However, a team of researchers recently embarked on a mission to Mount Waddington, the tallest and coldest mountain in British Columbia, to prove otherwise. They hoped to retrieve ice cores that would shed light on the climate history of the Pacific Northwest.

Drilling into the Unknown

The research team faced challenges in drilling the cores due to the relatively warm conditions. They had to drill during the evening hours when the ice was colder and use specialized equipment to prevent the ice from melting.

To their surprise, the core they retrieved was almost clear rather than the expected banded blue and white. This raised concerns that water may have infiltrated the ice layers and corrupted the data.

Analyzing the Cores

The researchers transported the core to a lab at the University of Washington at Seattle for further analysis. They used chemical analysis to differentiate between layers of summer dust and winter ice. The amount and type of dust can indicate past climate conditions, such as droughts or forest fires.

The scientists also measured the ratio of isotopes of oxygen and hydrogen to determine past temperatures. Heavier isotopes tend to fall out of colder air, providing a record of temperature fluctuations.

Glaciers and Ecosystems

Glaciers not only hold valuable climate data but also support unique ecosystems. They create crevasses and valleys, push up earth and rock, and reflect heat. Certain algae grow on ice, providing food for insects like ice worms. Birds and other animals rely on these creatures for survival.

Glaciers also regulate water flow, create pockets of fog, and release cold water into rivers. These processes are essential for maintaining healthy ecosystems and providing water resources for human populations.

Climate Change and Glaciers

As the Earth’s temperature rises due to climate change, glaciers are particularly vulnerable. Increased precipitation falls as rain rather than snow, dissolving ice and snowpacks. This process, known as glacier melt, is already occurring in the Pacific Northwest.

Glacier melt has significant consequences for both ecosystems and human populations. It reduces water availability, increases the risk of flooding, and disrupts the habitats of plants and animals that depend on glaciers.

The Urgency of Studying Mid-Latitude Glaciers

The Pacific Northwest is home to mid-latitude glaciers, which are highly sensitive to climate change. These glaciers are melting rapidly, and their climate records will soon be lost forever.

Scientists emphasize the urgent need to study mid-latitude glaciers before they disappear. By understanding the climate history these glaciers hold, we can better predict future climate changes and mitigate their impacts.

Glaciers serve as invaluable archives of our planet’s climate history. Studying ice cores from glaciers, particularly in understudied regions like the Pacific Northwest, provides crucial insights into past climate conditions and helps us prepare for the challenges of a changing climate.

The Ultimate Guide to Allergy-Friendly Flowers: A Comprehensive Resource for Hay Fever Sufferers

by Keira
written by Keira

Flowers for Allergy Sufferers: A Comprehensive Guide

Understanding Allergies and Flowers

Allergies, particularly hay fever, are a common response to pollen, a fine powder released by plants for reproduction. When pollen comes into contact with the mucous membranes of the nose, eyes, throat, or lungs, it triggers an immune response that can cause a range of symptoms, including sneezing, runny nose, congestion, itchy eyes, and difficulty breathing.

Flowers and Pollen

Not all flowers produce significant amounts of pollen, and some flowers have pollen that is not easily dispersed by the wind, making them less likely to trigger allergies. Additionally, some flowers have been bred to produce less pollen, making them more suitable for allergy sufferers.

Good Flowers for Allergy Sufferers

The following flowers are generally considered to be allergy-friendly:

  • Azaleas: Azaleas have pollen that is rarely released into the air, making them a good choice for allergy sufferers.
  • Begonias: Begonias produce very little pollen and have showy flowers that come in a wide range of colors.
  • Bougainvillea: The colorful “flowers” of bougainvillea are actually modified leaves, and the true flowers, which are small and white, produce very little pollen.
  • Cactus: Cacti have flowers that require cross-pollination from another cactus plant, but they do not rely on the wind to disperse it.
  • Camellia: Camellias have “perfect” flowers, meaning they have both male and female reproductive organs on the same flower, so their pollen does not have to travel far for pollination.
  • Clematis: Most clematis vines do not cause allergies, except for the sweet autumn clematis and the virgin’s bower.
  • Coleus: Coleus plants are grown primarily for their colorful foliage, and they produce very little pollen.
  • Columbine: Columbine flowers have brush-like stamens that may appear to be full of pollen, but they actually rely on nectar-loving birds and insects for pollination.
  • Geranium: Perennial geraniums produce very little pollen, and there are even pollen-free varieties available.
  • Hibiscus: Hibiscus flowers produce heavy pollen, but it is not airborne, making it less likely to cause allergies.
  • Hosta: Hosta plants are known for their attractive foliage, and their flowers are often removed before they bloom, eliminating any potential allergy concerns.
  • Hydrangea: Most hydrangea cultivars are not irritants, but some sensitive individuals may want to avoid ‘Pee Gee’ hydrangeas and ‘Oak Leaf’ hydrangeas.
  • Impatiens: Impatiens plants have large, sticky pollen particles that are too heavy to be picked up by the wind.
  • Bearded Iris: Iris flowers are designed to attract bumblebees for pollination, and their pollen is not windborne.
  • Lilies: Lilies have a good amount of pollen, but it is easy to remove the stamens and pollen-laden anthers.
  • Orchid: Orchid pollen does not often trigger allergic reactions, but some sensitive individuals may experience hay fever, especially if the plant is indoors.
  • Petunia: Petunia pollen is not considered an allergen, although the plants may emit a strong scent when grown in large numbers.
  • Phlox: Phlox pollen is not airborne, making it a good choice for allergy sufferers.
  • Roses: Most roses do not trigger hay fever, but wild species roses may be more likely to cause problems. Roses with dense petals release less pollen than single flowers.
  • Snapdragon: Snapdragons have flowers that keep their pollen contained, making them a good choice for both spring and fall gardens.
  • Spring Bulbs: Spring bulbs, such as crocus, daffodils, hyacinth, and tulips, are generally self-pollinating and have low pollen counts.
  • Sea Thrift: Sea thrift’s pink or white flowers rely on bees for pollination and should not cause hay fever.
  • Verbena: Verbena plants attract pollinators but do not produce windborne pollen.
  • Viola and Pansy: The thick, sticky pollen of violas and pansies is too heavy to be caught up in the wind.
  • Zinnia: Newer hybrid zinnias do not appear to cause problems for most people with allergies, despite being part of the Aster genus, which contains many species that trigger hay fever.

Worst Flowers for Allergy Sufferers

The following flowers are known to produce significant amounts of windborne pollen and should be avoided by allergy sufferers:

  • Aster
  • Baby’s breath
  • Dahlia
  • Daisies
  • Chamomile
  • Chrysanthemums
  • Ragweed
  • Sunflowers
  • Amaranth
  • Ornamental grasses
  • English lavender

Tips for Reducing Allergy Symptoms from Flowers

  • Choose allergy-friendly flowers for your garden.
  • Remove the stamens and pollen-laden anthers from flowers that have a lot of pollen.
  • Keep flowers well-watered to reduce pollen release.
  • Avoid being near flowers when they are in bloom.
  • Wear a mask or use a nasal spray when working with flowers.

Additional Considerations

  • Some highly fragrant flowers, even those that do not aggravate allergies, can still be irritants with their potent scents.
  • It is important to note that individual sensitivities may vary, so it is always a good idea to test a new plant in a small area before planting it widely in your garden.
  • Consult with a healthcare professional or allergist for personalized advice on managing allergies and selecting appropriate flowers for your specific needs.

Moose Spit: Nature’s Antifungal Weapon

Moose, known for their impressive antlers and large size, possess a unique adaptation that helps them thrive in their forest habitats: antifungal saliva. This remarkable fluid plays a crucial role in keeping the fungus on their favorite foods in check, ensuring their health and well-being.

Antifungal Properties of Moose Saliva

Biologist Dawn Bazely, in collaboration with the Toronto Zoo, has conducted extensive research on the properties of moose spit. Her findings have revealed that both moose and European reindeer saliva possess potent antifungal properties that protect them from the harmful effects of fungi.

Fungi are microscopic organisms that can produce toxins that can make moose sick if consumed in large quantities. To combat this threat, moose have evolved to produce saliva that suppresses fungal growth. Bazely’s experiments demonstrated that moose drool applied to grass samples significantly reduced the production of toxins within a day.

How Moose Use Their Antifungal Spit

While researchers are still investigating the exact mechanisms by which moose use their antifungal saliva, they speculate that it may serve multiple purposes. One possibility is that moose use their saliva to keep fungus levels in their home turf in check, ensuring a safe and healthy environment for themselves and their offspring.

Another theory suggests that moose may use their spit to protect themselves from fungal infections. By applying saliva to their food before eating, they may reduce the risk of ingesting harmful toxins. However, more research is needed to fully understand how moose utilize their antifungal saliva in their daily lives.

Beyond Moose: Antifungal Properties in Other Animals and Humans

Moose are not the only animals that possess antifungal saliva. Human saliva also exhibits antifungal properties, providing us with a natural defense against fungal infections. In 2008, Dutch scientists discovered that human saliva contains a compound that promotes wound healing, offering potential benefits for people with foot ulcers.

Medicinal Value of Saliva

The medicinal properties of saliva are often overlooked, but research is increasingly revealing its potential health benefits. In addition to its antifungal and wound-healing properties, saliva may also play a role in maintaining oral health, regulating digestion, and protecting against certain diseases.

Conclusion

Moose spit, with its remarkable antifungal properties, is a testament to the incredible adaptations that animals have evolved to survive in their environments. As research continues to uncover the medicinal value of saliva, we may discover even more ways that this humble fluid contributes to our health and well-being.

What Is an Echidna? A Unique Monotreme from Australia and New Guinea

by Peter
written by Peter

What Is an Echidna? A Unique Monotreme from Australia and New Guinea

Introduction

The echidna, also known as the spiny anteater, is a fascinating monotreme native to Australia and New Guinea. Monotremes are a unique group of mammals that lay eggs instead of giving birth to live young. The echidna is one of only two living species of monotremes, the other being the duck-billed platypus.

Physical Characteristics

Echidnas are characterized by their stocky bodies covered in defensive spines. They have a long, slender snout, or “beak,” which they use to unearth termites, ants, and worms. Echidnas have no teeth, so they use their long tongues to grind their food against the roof of their mouths.

There are two species of echidnas: the short-beaked echidna (Tachyglossus aculeatus) and the long-beaked echidna (Zaglossus bruijni). The short-beaked echidna is found throughout Australia and New Guinea and is well-adapted to a wide range of habitats. The long-beaked echidna, however, is found only in the tropical rainforests of New Guinea and is considered an endangered species due to habitat loss and hunting.

Behavior and Defense Mechanisms

Echidnas are solitary animals that spend most of their time foraging for food. They are not particularly good at running, so they rely on their sharp spines and their ability to curl into a ball for protection from predators. Echidnas also have an extra-long claw on one toe that they use to clean between their spines.

When an echidna encounters a predator or enemy, it will typically curl into a ball, presenting its sharp spines outward. It may also wedge itself into a space beneath a rock or burrow into the soil to escape.

Reproduction

Like all monotremes, echidnas lay eggs. Female echidnas lay a single egg each year, which they keep in a pouch on their abdomen. The egg hatches after about 10 days, and the baby echidna, called a puggle, remains in the pouch for several months until it is fully developed.

Historical Significance

The first Western person to encounter an echidna and write about it was William Bligh, the infamous captain of the Bounty. In 1792, Bligh’s ship stopped in Tasmania on its way to Tahiti. Bligh described the echidna as having a “beak like a duck” and a “thick brown coat of hair, through which the points of numerous quills of an inch long projected.”

Other Monotremes

The echidna is not the only monotreme in the world. The other monotreme is the duck-billed platypus, which is also found in Australia. Platypuses are similar to echidnas in that they lay eggs and have a long snout, but they are also characterized by their unique duck-like bill.

Conclusion

The echidna is a fascinating and unique monotreme that is an important part of the Australian and New Guinea ecosystems. Its unusual physical characteristics, behavior, and reproductive strategies make it a captivating subject for study and observation.

Tongues: Their Diverse Functions and Adaptations

Introduction

Tongues are fascinating organs that play a vital role in our daily lives. They enable us to taste, talk, and swallow, but their capabilities extend far beyond these basic functions. In the animal kingdom, tongues exhibit a remarkable diversity of adaptations that allow creatures to survive and thrive in their respective environments.

Types of Tongues

  • Alligator Snapping Turtle: This turtle possesses a worm-shaped appendage on the end of its tongue. It lies motionless in the water, mouth open, luring fish with its tongue before quickly snapping its trap shut.

  • Chameleon: Chameleons have extremely fast tongues that they shoot out of their mouths to capture prey. Biologists have calculated their tongue speed to be an astonishing 13.4 miles per hour.

  • Salamander: Salamanders have tongues that can shoot out with explosive force to capture fast-moving insects. Their tongues generate an impressive 18,000 watts of power per kilogram of muscle.

  • Snake: The forked tongue of a snake serves both taste and smell functions. Its shape provides directional information, aiding the snake in locating prey.

  • Giraffe: Giraffes have long, blue-black tongues that they use to reach around acacia thorns and grab leaves. The tongue’s color likely protects it from sunburn.

  • Hummingbird: Hummingbirds drink nectar with their tongues, which were once thought to function like straws. However, recent research has revealed that their tongues are more like forks with tiny fringes that trap the liquid.

  • Cat: Cats lap up liquid by curling their tongues backward and using hydrodynamics to bring up small amounts of milk or water with each sip. Their sandpaper-like tongues also serve as grooming tools.

  • Blue-Tongued Skink: This lizard uses its blue tongue to startle and scare off predators.

  • Giant Anteater: Giant anteaters have tongues that can be up to two feet long and extend into their thorax. They cover their tongues with sticky saliva to help them gather ants.

  • Tongue-Eating Louse: This tiny parasite enters a fish through its gills and attaches itself to the fish’s tongue. It feeds on the tongue’s blood, causing it to atrophy and eventually replacing it in the fish’s mouth.

Functions of Tongues

  • Taste: Tongues contain taste buds that allow us to experience different flavors.

  • Speech: The tongue plays a crucial role in producing speech sounds.

  • Swallowing: The tongue helps to move food from the mouth to the esophagus.

  • Grooming: Some animals, such as cats, use their tongues for grooming purposes.

  • Defense: Certain animals, such as the blue-tongued skink, use their tongues as a defensive mechanism to startle predators.

  • Prehension: Chameleons and anteaters use their tongues to capture prey.

  • Sensory Perception: Snakes use their forked tongues to gather information about their surroundings.

Conclusion

Tongues are incredibly versatile organs that have evolved to meet the diverse needs of different species. From the worm-shaped lure of the alligator snapping turtle to the lightning-fast tongue of the chameleon, these fascinating appendages play a crucial role in the survival and behavior of animals around the world.

Albatross: A Bird of Wonder and a Symbol of Conservation | Threats, Importance, and How to Help

by Rosa
written by Rosa

Albatross: A Bird of Wonder and a Symbol of Conservation

Introduction

Albatrosses are magnificent birds that have captured the imagination of humans for centuries. Their incredible wingspans, graceful flight, and long migrations have made them a symbol of freedom and adventure. However, these majestic creatures are facing threats that could lead to their extinction.

The Albatross and Literature

One of the most famous depictions of an albatross is in Samuel Taylor Coleridge’s poem “The Rime of the Ancient Mariner.” In the poem, the mariner shoots an albatross, an act that brings bad luck and災难 upon his ship and crew. This story has been interpreted as a warning about the dangers of harming the natural world.

The Biology of Albatrosses

Albatrosses are seabirds that belong to the family Diomedeidae. They are characterized by their large size, long wings, and webbed feet. Albatrosses are found in all the world’s oceans, but they are most common in the Southern Hemisphere.

Albatrosses are predators that feed on fish, squid, and krill. They have a unique hunting technique called “dynamic soaring,” which allows them to glide over the ocean’s surface for long periods of time without flapping their wings.

Albatrosses are social birds that live in colonies. They form lifelong bonds with their mates and return to the same nest site year after year. Albatrosses typically lay one egg per year, which is incubated by both parents.

The Threats Facing Albatrosses

Albatrosses are facing a number of threats, including:

  • Bycatch: Albatrosses are often accidentally caught in fishing nets. This is a major cause of death for albatrosses, particularly for species that feed near the ocean’s surface.
  • Pollution: Albatrosses can ingest plastic and other pollutants, which can cause health problems and death.
  • Climate change: Climate change is altering the ocean’s ecosystems, which is making it more difficult for albatrosses to find food.

The Importance of Conservation

Albatrosses are an important part of the marine ecosystem. They help to control populations of fish and squid, and they play a role in nutrient cycling. Albatrosses are also a valuable resource for humans. They provide food, feathers, and other materials.

It is important to protect albatrosses and their habitats. We can do this by:

  • Reducing bycatch: We can reduce bycatch by using fishing gear that is less likely to harm albatrosses.
  • Reducing pollution: We can reduce pollution by properly disposing of trash and recycling.
  • Supporting conservation organizations: We can support organizations that are working to protect albatrosses and their habitats.

The Albatross and the Mariner

The story of the Ancient Mariner is a reminder of the importance of respecting the natural world. Albatrosses are magnificent creatures that deserve our protection. By working together, we can ensure that these birds continue to soar through the skies for generations to come.

Additional Long-Tail Keywords:

  • How to identify different species of albatross
  • The unique feeding habits of albatrosses
  • The role of albatrosses in the marine ecosystem
  • The economic importance of albatrosses
  • The challenges facing albatross conservation

Animal Fluorescence: A Glowing Phenomenon in Nature

by Rosa
written by Rosa

Animal Fluorescence: A Glowing Phenomenon

Fluorescence is a fascinating natural phenomenon in which certain substances emit light after absorbing ultraviolet (UV) radiation. This ability is not limited to the animal kingdom, but is also found in minerals and fossils.

Animal Fluorescence

Many animals have the ability to fluoresce, including:

  • Birds: Puffins, crested auklets, and other seabirds have fluorescent beaks.
  • Insects: Scorpions, stick insects, millipedes, and grasshoppers all fluoresce thanks to their outermost layer.
  • Arthropods: Many arthropods, including crustaceans and crinoids, also fluoresce.
  • Frogs: The South American Polka-dot tree frog is the first known frog to naturally fluoresce.

Purpose of Animal Fluorescence

The purpose of animal fluorescence is not fully understood, but scientists have proposed several possible explanations:

  • Night vision: Fluorescence could help animals see in the dark by converting UV light from the moon and stars into visible light.
  • Communication: Fluorescence could be used for communication between animals, such as attracting mates or deterring predators.
  • Camouflage: Fluorescence could help animals camouflage themselves by matching the wavelength of light emitted by their surroundings.

How Does Animal Fluorescence Work?

Animal fluorescence is caused by the absorption of UV light by certain molecules in the animal’s body. These molecules then emit light at a longer wavelength, which is visible to the human eye.

In the case of puffins, the fluorescence is caused by a substance in the coating of the beak’s ridges. This substance absorbs UV light and re-emits it as a glow.

Other Fluorescent Substances

In addition to animals, many other substances can also fluoresce, including:

  • Minerals: Many minerals, such as calcite and fluorite, fluoresce under UV light.
  • Fossils: Fossilized organic material can fluoresce if it has been replaced by the mineral apatite.

Applications of Animal Fluorescence

Scientists are studying animal fluorescence to learn more about the evolution and behavior of different species. Fluorescence can also be used for practical applications, such as:

  • Medical imaging: Fluorescence is used in medical imaging techniques to visualize blood flow and other biological processes.
  • Forensic science: Fluorescence can be used to detect bloodstains and other evidence at crime scenes.
  • Gemology: Fluorescence is used to identify and grade gemstones.

Ongoing Research on Puffin Beak Fluorescence

Researchers are still studying the phenomenon of puffin beak fluorescence. They are working to determine:

  • The exact substance that causes the fluorescence
  • The purpose of the fluorescence
  • Whether the fluorescence is found in all puffin species

Scientists are also conducting experiments to test the effects of UV radiation on puffin eyes. They have developed special sunglasses for puffins to protect their eyes from damage.

Conclusion

Animal fluorescence is a fascinating and complex phenomenon that is still being studied by scientists. This ability to emit light has important implications for the evolution, behavior, and communication of different species. As research continues, we will learn more about the many ways that animals use fluorescence to their advantage.

Total Lunar Eclipse: A Rare Celestial Event for the Western Hemisphere

by Rosa
written by Rosa

Total Lunar Eclipse: A Rare Celestial Phenomenon

What is a Total Lunar Eclipse?

A total lunar eclipse occurs when the Earth’s shadow completely covers the moon, turning it a deep red color. This happens when the sun, Earth, and moon are perfectly aligned, with the Earth in the middle.

Tonight’s Total Lunar Eclipse

Tonight, skywatchers in the Western Hemisphere will have the opportunity to witness a total lunar eclipse. This is the first of a rare series of five total lunar eclipses that will occur over the next two years.

The eclipse will begin around 2 a.m. Eastern time, on Tuesday morning, when the moon will start to move into the Earth’s shadow. From 3:06 to 4:24 am, the moon will be fully immersed in the Earth’s shadow, blocking all sunlight from reaching it.

Why Are Lunar Eclipses More Common Than Solar Eclipses?

Lunar eclipses are more common than solar eclipses because they are less dependent on the precise alignment of the sun, Earth, and moon. For a solar eclipse to occur, the moon must pass directly between the sun and Earth. This only happens about once every 300 years at any given location on Earth.

In contrast, lunar eclipses can be viewed almost anywhere on the night side of the Earth, provided it is clear. This is because the Earth’s shadow is much larger than the moon, so it is more likely to cover the moon completely.

How to Watch Tonight’s Eclipse

If you want to watch tonight’s eclipse, find a spot with a clear view of the eastern horizon. The eclipse will be visible from anywhere in the Western Hemisphere, weather permitting.

If you are unable to see the eclipse in person, you can watch it live online through NASA or the SLOOH observatory.

Other Upcoming Total Lunar Eclipses

According to an online eclipse calculator, the nation’s capital should be in for another total lunar eclipse in October, and another next fall. Such a high frequency of recurring eclipses is a rare occurrence.
