how do you actually discover stuffs out the outer space?

Answer 1

telescopes. that guy that commented before me is wrong. radio telescopes are used, but so are optical, infrared, and x-ray telescopes as well. and it doesnt take an expert to interpret them, just someone who is educated in astronomy, like myself. hope this helps!!!!

Answer 2

Have you ever seen the movie 'The Stuff'?

The plot involves an insidious white glop that is discovered by miners. Upon tasting it, they discover it has a sweet and highly addictive taste. Later the slime is marketed as "The Stuff" and sold to general public in pint containers like ice cream. The Stuff becomes a nation wide craze and drasticallly hurts the sales of ice cream companies. An industrial saboteur is hired by the leaders of the suffering ice cream industry to find out exactly what the Stuff is and destroy it. His efforts reveal that the Stuff craze is far more sinister than anyone had thought. The Stuff is actually alive and gradually takes over the brain, mutating those who eat it into bizarre zombie-like creatures. No mention of outer space though, Sorry!

Answer 3

Outer space which is even beyond the sight o the giant astronomical telescopes is reached via the technology of radio telescopes.these instruments use radio waves to take pics of outer space,though these pics are not for people like us and can only be interpreted by experts.
