How does Hubble space telescope work?
Hubble is a type of telescope known as a Cassegrain reflector. Light hits the telescope’s main mirror, or primary mirror. Telescopes actually work by collecting more light than the human eye can capture on its own. The larger a telescope’s mirror, the more light it can collect, and the better its vision.
Where is Hubble Space Telescope?
Hubble orbits in low Earth orbit at an altitude of approximately 540 kilometers (340 mi) and an inclination of 28.5°.

Did Neil Armstrong leave bracelet on moon?
But instead of a bracelet, Armstrong brought one of Karen’s shoes to the moon. During the film, Armstrong on a few occasions gazes longingly at the moon.

Does life exist on the moon?
The moon may have more water and oxygen than Earth and an oxygen exosphere. Thought to have a subsurface liquid water ocean due to tidal heating or geothermal activity. Free molecular hydrogen (H2) has been detected, providing another potential energy source for life.
Can we live on Sun?
This is the surface of the sun we see every day. But if you take a look around, there’s nothing here for you to actually land on, because the sun doesn’t have any solid surface to speak of. It’s just a giant ball of hydrogen and helium gas. So instead of landing on the photosphere, you’re going to sink into it.
