- Year Discovered: 1979
- Location: Ursa Major Constellation
For those unaware, a quasar is a highly active galactic nucleus. Within it, a supermassive black hole, millions to billions of times the mass of the sun, is surrounded by a gaseous accretion disk. Once this disk falls, energy is then released as electromagnetic radiation. The radiation is quite powerful with just one, but two? The Hubble Space Telescope observed a double-quasar phenomenon in 1979, which appears to have been in place from the early universe.
In fact, it was this discovery that aided in helping us find out that the universe was expanding faster than we knew. This alone is one of the freakiest things NASA discovered, but the double-quasar situation itself is crazy. We know these only really exist when galaxies are merging. In this situation, NASA assumed they were one quasar initially. It was the very first gravitationally lensed object humans discovered too. What a way to blow the world’s mind all at one time.
