No, not yet at least. The only object that astronauts have been to other than Earth is the moon, which is a moon rather than a planet. There other planets are much farther away, but there are some plans to land people on Mars.
They could, but as of now, no astronauts have travelled to any other planets in the solar system.
I would suppose that the scientist with the super powered telescopes would discover planets before the astronauts would.
Space astronauts went to the planets to be sure there is no life on planets
What scientist and astronauts search for is mainly signs of life. To see if you can live on any of the planets. THANK YOU

Astronauts can see planets, stars, and species.

No
The only place astronauts have been other than Earth, is on the moon. When they were there, they did some exploring to see what it was like. They took samples of the soil and rocks to bring back to Earth. They tried to learn as much as they could while they were there. If astronauts get to visit other planets, they would do the same kinds of things.
Well, to explore space ofcourse. Astronauts go to space to find new planets or such. They observe what is happening.
None. Their had only reach the moon.
