The Hubble Space Telescope revealed the vast breadth of the cosmos and innumerable galaxies before unseen, by capturing millions of galaxies in a tiny area of sky.
On a pulsar's orbit, the first exoplanet to be confirmed was discovered. Thousands more have been found since then, changing our knowledge of planetary systems and possible extraterrestrial life.
The Big Bang theory was directly supported by the finding of CMB radiation, which traced the evolution of the universe and revealed traces of its earliest beginnings.
LIGO's detection of gravitational waves verified Einstein's theory. A new age of cosmic observations was ushered in by these black hole merger-induced rippling effects in spacetime.
In the galaxy M87, the Event Horizon Telescope obtained the first-ever picture of a black hole, providing visual evidence for one of Einstein's most well-known predictions.
Voyager 1 was the first artificial object created by humans to leave the solar system, and it delivered ground-breaking information on the regions of space outside the solar system.
The paradigm in cosmology was shifted when it was realized that dark matter and dark energy, which are invisible forces that control the expansion of the universe, make up 95% of the universe.
