How come the black skies of the Moon contain no stars in Chang'e photos? The answer: The stars are there, they're just too faint to show up.
Just like on Earth, sunlight makes it all but impossible to see other stars in the sky, even while on the Moon.
Why can't we see stars in the pictures of spacewalking or moonwalking astronauts? The stars aren't visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures.
It isn't completely black in space. There is a lot of light, but that light is only visible when looking at the source or when looking at an object from which the light has reflected.
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 ...
But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.
We can see that with the right equipment and enough time, astronauts are able to observe many stars as well as the Milky Way, our home galaxy! They experience night about 16 times a day, which gives them many opportunities to observe the stars.
In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together.
The shuttle/ISS Extravehicular Mobility Unit (EMU) aka spacesuit incorporates a gold-film plated sun visor to protect the astronaut's vision when looking in the general direction of the sun. It is called the Extravehicular Visor Assembly.
Small, old stars can be at room temperature ex: WISE 1828+2650, so you could touch the surface without getting burned. Any star you can see in the sky with the naked eye, however, would be hot enough to destroy your body instantaneously if you came anywhere near them.
Myths about astronaut requirements
As a teenager, I was told that getting a tattoo would mean I could never be an astronaut. This is not at all true. In fact, some Apollo astronauts were given tattoos– small dots to show where defibrillator pads should be placed in case of a medical emergency.
No, there isn't sound in space.
This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.
Yes, the flag is still on the moon, but you can't see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.
Apollo astronauts reported they could see the brighter stars if they stood in the shadow of the Lunar Module, and also they saw stars while orbiting the far side of the Moon. Al Worden from Apollo 15 has said the sky was "awash with stars" in the view from the far side of the Moon that was not in daylight.
What is the star by the moon? The light isn't actually a star, despite sometimes being referred to as the Evening Star - instead it's the planet Venus and it's the second closest planet to the sun.
It turns out that if the universe was infinitely large and infinitely old, then we would expect the night sky to be bright from the light of all those stars. Every direction you looked in space you would be looking at a star. Yet we know from experience that space is black!
The earth is rotating at a tilted axis relative to the sun, and during the summer months, the North Pole is angled towards our star. That's why, for several weeks, the sun never sets above the Arctic Circle.
Space emits many wavelengths of light - including a lot of blue and red light that our human eyes can see - but also ultraviolet light, gamma rays, and X-rays, which remain invisible to us.
Stars don't burn – two hydrogen atoms fuse to make helium which is a process which releases a lot of energy.
Did you know that there are storms always occurring in space? Not rain or snow, but winds and magnetic waves that move through space! This is known as space weather.
Images taken by the Lunar Reconnaissance Orbiter (LRO) have shown that the American flags left on the Moon by Apollo astronauts are still standing– except for the Apollo 11 mission, which Buzz Aldrin reported as being knocked over by engine exhaust as Apollo 11 lifted off.
Six missions landed humans on the Moon, beginning with Apollo 11 in July 1969, during which Neil Armstrong became the first person to walk on the Moon. Apollo 13 was intended to land; however, it was restricted to a flyby due to a malfunction aboard the spacecraft. All nine crewed missions returned safely to the Earth.
Cost To Go To the Moon
Taking that as 1973 dollars, that's roughly equivalent to a little over $157 billion in dollars today, or about $9.3 billion a year.
