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
Telescopes.
Planets do not technically need their respective stars, but stars keep planets in orbit and provide heat and light to the planets.

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 stars emitt its own light. But the planets do not have any own light. It absorbs the light from the stars like a sun. It just reflects the light. And also the stars are far away from the earth than the planets. So we can found the twinkling of stars but not the planets.
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.
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
None of the planets are stars, only the stars. See related questions.
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.
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.
