description Overview

Hipparcos

Hipparcos was a European Space Agency observatory launched in 1989. It performed groundbreaking measurements of stellar positions and distances using parallax – tiny shifts in apparent position caused by Earth’s orbit. This data significantly improved our understanding of the Milky Way galaxy's structure and star populations, primarily benefiting astronomers studying galactic dynamics and stellar...

Planck

The Planck mission was a European Space Agency-operated observatory designed to study the Cosmic Microwave Background (CMB). Launched in 2009 and decommissioned in 2013, it provided highly detailed measurements of this afterglow from the Big Bang. This data is invaluable for cosmologists studying the early universe’s composition, geometry, and evolution. Researchers utilizing Planck's results incl...
