List of space telescopes

Space telescopes that collect particles, such as cosmic ray nuclei and/or electrons, as well as instruments that aim to detect gravitational waves, are also listed.

Gamma-ray telescopes collect and measure individual, high energy gamma rays from astrophysical sources.

Optical telescopes are used to look at planets, stars, galaxies, planetary nebulae and protoplanetary disks, amongst many other things.

Typical targets for observations include supernova remnants, masers, gravitational lenses, and starburst galaxies.

[citation needed] Spacecraft and space-based modules that do particle detection, looking for cosmic rays and electrons.

There are also Ultra-high-energy cosmic rays from active galactic nuclei, those can be detected by ground-based detectors via their particle showers.

A type of telescope that detects gravitational waves; ripples in space-time generated by colliding neutron stars or black holes.
