Why Does The Moon Have Dark Spots

Why Does The Moon Have Dark Spots?

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. The light areas are the highlands which are mountains that were uplifted as a result of impacts.

What is the dark 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.

Why are some parts of the Moon dark?

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.

Will footprints on the moon last forever?

An astronaut’s footprint can last a million years on the surface of the moon. It may have been decades since we last set foot on the moon but its surface is still marked with the historic footprints of the 12 astronauts who stomped across it. That’s because the moon has no atmosphere.

Is the flag still in 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.

Why is the Moon GREY?

That gray color you see comes from the surface of the Moon which is mostly oxygen silicon magnesium iron calcium and aluminum. The lighter color rocks are usually plagioclase feldspar while the darker rocks are pyroxene. … They’re less reflective than the lunar highlands and so they appear darker to the eye.

Why don’t we ever see the dark side of the Moon?

First the dark side isn’t really any darker than the near side. Like Earth it gets plenty of sunlight. We don’t see the far side because “the moon is tidally locked to the Earth ” said John Keller deputy project scientist for NASA’s Lunar Reconnaissance Orbiter project. … Earth’s gravitational pull holds it in place.

What is the dark side of the Moon look like?

Compared to the near side the far side’s terrain is rugged with a multitude of impact craters and relatively few flat and dark lunar maria (“seas”) giving it an appearance closer to other barren places in the solar system such as Mercury and Callisto.

Do you age in space?

We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved and it can be warped by matter and energy. … And for astronauts on the International Space Station that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

What Did Neil Armstrong do on the moon?

Neil Armstrong was a NASA astronaut most famous for being the first person to walk on the moon on July 20 1969.

Can you survive in space for 30 seconds?

This could occur in as little as 15 seconds. … This process could take from 30 seconds to 1 minute. So it was possible for astronaut David Bowman in “2001: A Space Odyssey” to survive when he ejected from the space pod into the airlock without a space helmet and repressurized the airlock within 30 seconds.

Can a telescope see the flag on the moon?

Yes the flag is still on the moon but you can’t see it using a telescope. … The Hubble Space Telescope is only 2.4 meters in diameter – much too small! Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter.

Can you float away from the moon?

There is no air on the moon but astronauts don’t float away – even when they jump. Here is John Young’s “jump salute”. And what about the Earth itself? Why does it orbit the Sun?

How long was the trip to the moon in 1969?

Armstrong became the first person to step onto the lunar surface six hours and 39 minutes later on July 21 at 02:56 UTC Aldrin joined him 19 minutes later.

What is the rarest moon color?

Blue-colored moons are rare – aren’t necessarily full – and happen when Earth’s atmosphere contains dust or smoke particles of a certain size. The particles must be slightly wider than 900 nanometers.Aug 19 2021

Why is moon yellow?

“It tends to have a more yellow or orange hue compared to when it’s high overhead. This happens because the moon’s light travels a longer distance through the atmosphere. “As it travels a longer path more of the shorter bluer wavelengths of light are scattered away leaving more of the longer redder wavelengths.”

Why is the Moon red?

Blood moon

As sunlight penetrates the atmosphere of Earth the gaseous layer filters and refracts the rays in such a way that the green to violet wavelengths on the visible spectrum scatter more strongly than the red thus giving the Moon a reddish cast.

Who is the last human stepped on the Moon?


During the Apollo 17 mission Cernan became the eleventh man to walk on the Moon. As he re-entered the Apollo Lunar Module after Harrison Schmitt on their third and final lunar excursion he is the last man to walk on the Moon as of 2021.

Does Moon rotate?

The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth. … Over time it has slowed down because of the effect of Earth’s gravity. Astronomers call this a “tidally locked” state because it will now remain at this speed.

How cold is the dark side of the Moon?

On the dark side of the moon with no sun temperatures can be as low as -232 degrees Celsius or -387 degrees Fahrenheit! It can get even lower than that is certain areas. The moon has a relatively minimal tilt.

How long till we lose the Moon?

Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth.

Can you see both sides of the Moon?

Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth—a situation known as synchronous rotation or tidal locking. The Moon is directly illuminated by the Sun and the cyclically varying viewing conditions cause the lunar phases.

Are there lava tubes on the Moon?

Lunar lava tubes are lava tubes on the Moon formed during the eruption of basaltic lava flows. … Lunar lava tubes are formed on sloped surfaces that range in angle from 0.4° to 6.5°. These tubes may be as wide as 500 metres (1 600 ft) before they become unstable against gravitational collapse.

Is an hour in space 7 years on Earth?

The first planet they land on is close to a supermassive black hole dubbed Gargantuan whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation where one hour on the distant planet equals 7 years on Earth.

How long is 1 second in space?

It is defined as the distance that light travels in free space in one second and is equal to exactly 299 792 458 metres (983 571 056 ft).

Can you get pregnant in outer space?

As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon.

Where is Neil Armstrong now?

He was spacecraft commander for Apollo 11 the first manned lunar mission and became the first man to walk on the moon. Armstrong died shortly after undergoing heart surgery in Cincinnati Ohio in 2012.

What happens when you fart in space?

Therefore the fart will not be smelled by the astronaut although they may marinate in it for a time. When astronauts are not in the space suit and floating about the fart smell is exaggerated by the lack of airflow from the recycled air used and its inability to mask any smell. … Same goes in space.

What does space smell like?

Astronaut Thomas Jones said it “carries a distinct odor of ozone a faint acrid smell…a little like gunpowder sulfurous.” Tony Antonelli another space-walker said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time when I …

How cold is space?

about -455 degrees Fahrenheit
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).Sep 25 2020

What happens if the Moon was closer to Earth?

Now moving the Moon closer to the Earth will increase the gravitational exertion of the satellite onto our planet. If the satellite were slightly closer the tidal bulge would grow. Low tides would be lower and high tides would be higher and any low lying coastline would be flooded.

Can the Moon crash into Earth?

Long answer: The Moon is in a stable orbit around Earth. There is no chance that it could just change its orbit and crash into Earth without something else really massive coming along and changing the situation. The Moon is actually moving away from Earth at the rate of a few centimetres per year.
