What are the methods to investigate the universe?

Answer 1

The universe can be explored by astronomical instruments called telescopes, and by space probes sent from earth to other planets. When using telescopes astronomers try to look at the energy being produced by the universe not just in the visible part of the spectrum (where our eyes can see) but at the whole range of electromagnetic radiation. We thus have radio telescopes, infrared telescopes, X-ray telescopes and even some telescopes that are buried deep underground looking for neutrinos.

I would like to add one more additional method for investigating universe, it just appeared in my brain.

well the method is being used in large hadron collider(which is a particle collider), in which smallest particle of any atom are collided at very high speed.

it tells us about the born of the universe, dat how did it happen.

They say "At Cern, the Large Hadron Collider could recreate conditions that last prevailed when the universe was less than a trillionth of a second old. It has massive particle detectors called the Compact Muon Solenoid."

Hubble telescope:

There are many telescopes that are strong enough to view space the main telescope is the Hubble telescope which was sent off in 1990, The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. A 2.4 meter (about 8 ft.) aperture telescope in low Earth orbit, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared. The telescope is named after the astronomer Edwin Hubble.

Satellite:

There are many methods used to investigate the universe, the main thing that is used to observe is all the different satellites that orbit around the earth that also have telescopes attached to them.

Radio telescope:

A radio telescope is a form of directional radio antenna used in radio astronomy. The same types of antennas are also used in tracking and collecting data from satellites and
