The Hubble Space Telescope observes the most distant single star ever. The star, named Earendel by astronomers, is 28 billion light-years away. It is the farthest detection of a star, dating back 900 million years after the Big Bang. This discovery surpasses Hubble's record from 2018, when it discovered a star that existed when the universe was roughly four billion years old.

The European Southern Observatory announces the discovery of Earth's closest-known black hole (HR 6819). The invisible object in the QV Telescopii system has a mass at least four times that of our Sun, and is roughly 1,000 light years (10 quadrillion km) from Earth in the constellation Telescopium.

Researchers at the Breakthrough Listen initiative announce they have detected 15 new powerful fast radio bursts (FRB) from FRB 121102, located in a dwarf galaxy about three billion light-years from Earth. FRB 121102 was first detected in 2012, and gained further attention after FRBs were detected from there again in 2015.

Space telescope observations indicate that the supernova RCW 86, first seen by Chinese astronomers in 185 AD, expanded at an unprecedented rate due to the formation of a vacuum-like "cavity" around it in the early stages of the death of its star. The supernova's rapid expansion had previously been one of astronomy's most enduring mysteries.
