Why are there dark patches on the moon?
The dark spots on the lunar surface are actually craters of varying sizes that formed due to collisions from celestial bodies, such as comets, meteorites and asteroids in the past, which left large, excavated holes after the impact.
What is the dark part of the moon called?
Capturing the dark side The 'dark side' of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. In reality it is no darker than any other part of the Moon's surface as sunlight does in fact fall equally on all sides of the Moon.
What is the largest dark spots on the Moon called?
- The surface of the moon is covered in huge dark spots, visible from Earth even with the naked eye. These patches are known as Maria – a Latin word meaning 'seas'.
- Maria are huge basins containing lava flows marked by craters, ridges, faults, and straight and meandering valleys called rilles and are devoid of water.
What are the shadows on the Moon?
The shadows cast by the roughness of the Moon's surface create small cold spots for water ice to accumulate even during the harsh lunar daytime. Scientists are confident that water ice can be found at the Moon's poles inside permanently shadowed craters – in other words, craters that never receive sunlight.
What is the darkest part of the Moon’s shadow called?
the umbra The darkest part of the moon's shadow is called the umbra. From any part of the umbra, the moon completely blocks, light from the sun. Only people in the umbra see a total solar eclipse.
What is the blue spot on the Moon?
For example, a dark blue spot located left of Mare Cirsium represents a feature called Mare Tranquillatis. The area, also known as the Sea of Tranquility, is where Apollo 11 landed during the lunar missions and where the first human footprints on the moon reside.
Why are shadows black on the Moon?
"Remember," adds Mitchell, "on the lunar surface there's no air to refract light–so unless you've got direct sunlight, there's no way in hell you can see anything. It was just pitch black. That's an amazing phenomenon on an airless planet."
What are the two parts of moons shadow?
During a solar eclipse, the Moon's shadow on Earth's surface is only about 300 miles (480 km) wide. The shadow consists of two parts, the umbra, where the Sun is completely blocked, and the penumbra, where the Sun is partially obscured.
What is the Moon’s faint shadow called?
The penumbra The Moon's shadow has two parts. The penumbra is the faint outer shadow, partial eclipses are seen from within this shadow. The umbra is the dark inner shadow, total eclipses are seen from within this shadow.
What is the Earth’s shadow on the Moon called?
A lunar eclipse occurs when the Moon passes through the Earth's shadow, just as a solar eclipse occurs when part of the Earth passes through the Moon's shadow.
What are the GREY spots on the Moon?
Those spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they're actually volcanic plains). The smooth and dark maria cover 17 percent of the surface of the moon. Almost all of them are visible from Earth.
What are moon shadows?
The amount of Moon we see changes over the month — lunar phases — because the Moon orbits Earth and Earth orbits the Sun. Everything is moving. During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.
How big are the dark spots on the Moon?
The largest dark spot on the moon, known as the Ocean of Storms, may be a scar from a giant cosmic impact that created a magma sea more than a thousand miles wide and several hundred miles deep, researchers say.
What do you call the darkness part of the Moon’s shadow?
One shadow is called the umbra which becomes smaller as it reaches the Earth. This is the dark center of the Moon's shadow. The second shadow is called the penumbra.
What is the darkest part of the Moon’s shadow?
the umbra The darkest part of the moon's shadow is called the umbra. From any part of the umbra, the moon completely blocks, light from the sun. Only people in the umbra see a total solar eclipse.
What is a penumbral shadow?
penumbra, (from Latin paene, “almost”; umbra, “shadow”), in astronomy, the outer part of a conical shadow, cast by a celestial body, where the light from the Sun is partially blocked—as compared to the umbra (q.v.), the shadow's darkest, central part, where the light is totally excluded.
What is called umbra?
During an eclipse, two shadows are cast. The first is called the umbra (UM bruh). This shadow gets smaller as it goes away from the sun. It is the dark center of the eclipse shadow. The second shadow is called the penumbra (pe NUM bruh).
Why are footprints on the Moon still there?
Unlike on Earth, there is no erosion by wind or water on the moon because it has no atmosphere and all the water on the surface is frozen as ice. Also, there is no volcanic activity on the moon to change the lunar surface features. Nothing gets washed away, and nothing gets folded back inside.
What type of rock makes up the dark spots on the moon?
When you look at the Moon, you will see dark and light areas. The dark areas are young plains called maria and are composed of basalt. The basalt flowed in and flooded the area created by a huge impact with an asteroid or comet.
What are the 12 phases of the moon?

What is difference umbra and penumbra?
(i) Umbra means ''shadow'' while ''penumbra'' means to hang on the shadow or almost a shadow. Also, penumbra was coined by Johannes Kepler whereas the coining of ''umbra'' is not attributed to anyone in particular. (ii) Umbra is the dark part while penumbra is the lighter part.
What is penumbra moon?
A penumbral lunar eclipse occurs when the Sun, Earth, and the Moon are imperfectly aligned. When this happens, the Earth blocks some of the Sun's light from directly reaching the Moon's surface and covers all or part of the Moon with the outer part of its shadow, also known as the penumbra.
Is the US flag still on the Moon?
Images taken by a Nasa spacecraft show that the American flags planted in the Moon's soil by Apollo astronauts are mostly still standing. The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows – except the one planted during the Apollo 11 mission.
What do astronauts do with their poop?
Astronauts say that “Today's coffee is tomorrow's coffee!” Sometimes, astronaut poop is brought back to Earth for scientists to study, but most of the time, bathroom waste — including poop — is burned. Poop is vacuumed into garbage bags that are put into airtight containers.
How much is a moon rock worth?
The samples were recovered, and NASA estimated their value during the ensuing court case at about $1 million for 10 oz (280 g) of material.
What is a Moon Wolf?
The first full moon in January has often been referred to as the Wolf Moon for centuries. Its origin comes from Native Americans who often heard wolves howling during cold winter nights at this time of year, according to the Farmer's Almanac.
Why do wolves howl on a full Moon?
Why do gray wolves howl at the moon? We hate to burst your bubble, but it is a myth that wolves howl at the moon! Howling may be heard at night, but it is not a behavior directed at the moon. Instead, it is used as a social rally call, a hail to hunt or as a territorial expression.
