HST, 20580

Orbit data source: Space-Track

The Hubble Space Telescope is a large observatory located in Earth's orbit that has transformed the field of astronomy. Launched in 1990, Hubble has made significant contributions to all domains of astronomy, such as determining the universe's age, the existence of dark energy, and the rate of its expansion. The telescope’s high-resolution images provide detailed and precise views of distant galaxies, nebulae, and star clusters, establishing it as one of the most important telescopes in the history of astronomy.
