Our eyes. Often augmented through the use of artificial devices
such as cameras, telescopes, and charge-coupled devices.
A spectrometer is used to determine the composition of stars, and how fast they are going relative to Earth.
Yes. To date scientists have discovered well over a thousand planets orbiting other stars. It is believe that a large portion of the stars in the night sky have planets.
Planets but the look like stars
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.

The reason you can see planets and stars at night is that their light is faint and the brightness of the sun obscures them during the day. At night, when the sun is not visible, the fainter light from the planets and stars can more readily be seen.
Astronauts can see planets, stars, and species.
The entire visible spectrum plus the infrared and ultraviolet. They are trying to obscure the stars light and see the faint reflections of any planets nearby.

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.
None of the planets are stars, only the stars. See related questions.
Planets but the look like stars
We can't even see individual STARS in other galaxies, much less PLANETS. We have no idea how many stars are there.
stars, planets, galaxies, darkness
Planets orbit stars.
You can see five of the planets in our Solar System with the naked eye - they appear as bright stars. To see Uranus and Neptune, you need telescopes.
