How do scientists collect data about our solar system and the universe?

Answer 1

Through telescopes. We have more ground based telescopes than we have instruments in space, though we have also learned a great deal through some space missions, such as through the COBE & WMAP satellites.

Optical telescopes provide a wealth of information, but we can see further using radiotelescopes, and we can penetrate deeper through clouds of interstellar gas with infrared telescopes.

Answer 2

Mainly by telescopes - both light telescopes, and specialized telescopes that receive and analyze other parts of the electromagnetic spectrum, such as x-rays, radio waves, etc.Also by actually sending probes out, who look at planets, comets, etc. from nearby, and send information back. With our current technology, this can only be done within the Solar System.

Answer 3

satellites, spaceships, astronauts and everything else into space
