Einstein Observatory

The Einstein Observatory, launched in 1978, was a space-based X-ray telescope that sought to study cosmic phenomena by observing X-rays emitted by high-energy objects like black holes, neutron stars, and supernova remnants. Named after Albert Einstein, it was the first of its kind to focus on X-ray astronomy, allowing scientists to uncover insights about the universe's most extreme environments. Operating until 1982, it significantly advanced our understanding of the cosmos, highlighting the importance of X-rays in revealing the hidden aspects of astronomical objects that are not visible in optical light.
