A CCD (Charge-Coupled Device) camera is a type of digital imaging device that converts light into electronic signals, which are then processed to form a digital image. It has revolutionized astronomy by providing high-resolution, low-noise images and revolutionized the way we capture and analyze astronomical data.

A facility designed to detect and study neutrinos, elusive particles that are produced by nuclear reactions in stars, including our sun. Neutrino astronomy is providing a unique window into processes like supernova explosions and nuclear fusion in stars.

Adaptive optics is a technology used in astronomical telescopes to compensate for the blurring effect of the Earth's atmosphere, resulting in sharper images. It has improved our ability to observe distant and faint objects in the universe in great detail.

A spectrograph is an instrument that separates light into a spectrum and records the signal using a camera. It has provided insights into the chemical composition, temperature, density, and velocity of celestial objects.

A gamma-ray telescope detects the highest-energy form of electromagnetic radiation. It has provided insight into the most energetic and exotic objects in the universe such as supernovae, neutron stars, pulsars, and active galactic nuclei.

Gravitational wave detectors like LIGO and Virgo detect ripples in space-time caused by massive celestial events such as the collision of black holes. This has opened a new window into the cosmos and confirmed a major prediction of Einstein's general theory of relativity.

A spectrometer measures the properties of light over a specific portion of the electromagnetic spectrum, typically used to identify the composition and physical properties of astronomical objects. This has led to the identification of elements and molecules in stars and interstellar space.

Radio telescopes detect radio waves from space and are essential for studying celestial objects that emit strongly at radio wavelengths like pulsars and quasars, as well as mapping the structure of the cosmos with the cosmic microwave background radiation.

A spacecraft that travels through space to collect data on astronomical objects and phenomena. It has provided up-close examinations and unprecedented detail of planets, moons, and comets, contributing vastly to our understanding of the solar system.

This instrument measures the intensity and brightness of light from astronomical objects. Photometry provides data on stellar luminosity, variable stars, exoplanet transits, and cosmological distances, which are fundamental for the stellar and galactic astrophysics.

A telescope collects and focuses light or other forms of electromagnetic radiation to create a magnified image of distant objects, allowing astronomers to observe celestial bodies far beyond the capabilities of the naked eye.
