cause they gather light and concentrate it.
X-ray telescopes are placed in orbit around the Earth to avoid absorption of X-rays by Earth's atmosphere. By being in space, these telescopes can capture high-energy X-ray emissions from celestial objects that do not reach the surface due to the atmosphere.
Some of the best telescopes are in orbit because the earth atmosphere distorts the light from distant stars,which is something scientist and astronomers would rather avoid.
We are on the Earth's surface. To be in the Earth we would have to be underground. Although it doesn't look as if we are in space, the very thin blue sphere around Earth is our atmosphere. To enter space we would go through that atmosphere. :D
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
We know the moon is round because of the way its surface appears when observed from Earth. Through telescopes and spacecraft, we can see that its shape is consistent with a sphere, curved in all directions. Additionally, the way shadows move across its surface during different phases further supports its roundness.

The weight of a space probe on the surface of Mars would be less than on Earth due to Mars having lower gravity. Mars has about 38% of Earth's gravity, so a space probe that weighs 1000 lbs on Earth would only weigh about 380 lbs on the surface of Mars.
No, you would not float into space on the moon. The moon has gravity, although it is about one-sixth of Earth's gravity. You would still be pulled towards the moon's surface, but you would feel lighter and be able to jump higher compared to on Earth.

Earth's atmosphere absorbs and scatters X-rays, preventing them from reaching the surface. To detect X-rays from distant stars, X-ray telescopes need to be placed in space above the atmosphere. This allows them to collect and study X-rays without interference.
The main advantage would be the absence of an atmosphere. Any telescope on earth can only "see" electromagnetic (light) waves after they have travelled through the atmosphere, losing some of their directional integrity, which distorts the image seen in earth bound telescopes. Some light waves never make it to the telescope at all.
Earth's Gravity would pull it straight down to earths surface.
It would fall to Earth's surface.
The astronaut would release the object outside of the space shuttle and let it fall towards Earth due to gravity. The object would follow a trajectory back to Earth's surface without the need for further propulsion.
