A highly sensitive photon detection device that converts light into electronic signals, commonly used in telescopes to image stars, planets, and other astronomical objects.

An instrument designed to detect neutrinos, which are nearly massless particles that rarely interact with matter, providing unique information about processes such as supernovae and nuclear reactions in the Sun.

A telescope located outside Earth's atmosphere, offering an unobstructed view of the universe in various wavelengths, such as the Hubble Space Telescope.

An observatory designed to detect ripples in spacetime caused by cataclysmic astrophysical events like collisions of black holes or neutron stars.

A telescope specially designed to detect X-rays from astronomical objects, which is crucial for studying high energy environments such as black holes, neutron stars, and supernova remnants.

A type of observatory equipped with a large parabolic antenna that detects radio waves emitted by celestial objects, enabling study of the universe at radio frequencies.

Astronomical observatory designed to detect gamma rays, the most energetic form of electromagnetic radiation, which are typically emitted by the most violent and hot events in the universe.

An instrument that separates light into its different wavelengths, allowing analysis of the spectral composition to determine the properties of celestial objects, such as their temperature, composition, and velocity.

An observatory that detects infrared radiation to observe objects in the universe that are not visible in the optical spectrum, such as newly formed stars, planets, and the centers of galaxies.
