People commonly look through telescopes to see into space. Telescopes are used by NASA to see stars and planets very far away, and less sophisticated models are used to see planets in our solar system, or even the moon.
X-ray telescopes are used to study mainly the Sun, stars and supernovas. X-ray telescopes work better at very high altitudes on the Earth's surface.
Earth based telescopes have to see through the atmosphere and all the dust it contains. space telescopes like Hubble have nothing but clearspace to see through.
If you look through them the wrong way round, everything looks smaller!

Radio telescopes detect stars known as 'Pulsars'. They're very small and also known as neutron stars.
using radio waves it collects the data.
We can, except we see them by the wobble of the star. The planet itself is too faint for our telescopes to see, but the gravitational pull the planet places on the star causes it to wobble and we can observe that through time-lapse observations.
Your eyes, binoculars, telescopes.
