Top 3 Groundbreaking Discoveries by Space Telescopes

Space telescopes have revolutionized our understanding of the universe, leading to pivotal discoveries that reshaped cosmology and our search for life beyond Earth.

The top 3

1. Accelerated Expansion of the Universe (Dark Energy): Hubble Space Telescope observations of distant supernovae in 1998 provided direct evidence that the universe's expansion is accelerating, implying the existence of a mysterious repulsive force called dark energy, which makes up about 69.4% of the universe.
2. Thousands of Exoplanets Discovered: Missions like Kepler and TESS have discovered thousands of exoplanets, with Kepler alone confirming over 2,600 and TESS identifying over 7,900 candidates and confirming 885, revolutionizing our understanding of planetary systems beyond our own.
3. Mapping the Cosmic Microwave Background: Early space missions like COBE, WMAP, and Planck precisely measured the cosmic microwave background (CMB) radiation, the afterglow of the Big Bang, providing crucial data on the universe's age, composition, and early structure.
