Can an astronaut touch a star?

Surprisingly, yes, for some of them. 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.

Why astronauts Cannot see stars?

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. With those camera settings, though, the stars don’t show up.

What happens to astronauts when they come back to Earth?

Can astronauts walk upright in space?

How much do astronauts lose when they go to space?

Astronauts can lose as much as 20 to 40 per cent muscle size and function during long trips in space, according to NASA. The two hours they spend exercising mitigates the deterioration to a degree, but, like with bone loss, astronauts go through a rehab program when they’re back on Earth to regain their muscle mass and strength.
