Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.
A quasar is a galactic object with a supermassive black hole in the center.

An astronomer and ‘black hole historian’ explains how the parts of the universe black holes grow in might influence how quickly they become bright, supermassive objects.
New data from the IceCube collaboration shows neutrino emissions from within our Milky Way galaxy – but figuring out where exactly these ghost particles come from is harder than it seems.
An x-ray of the brightest ever gamma ray burst reflected off dust layers, creating extended ‘light echoes’ of the initial blast.

Artificial intelligence tools are making waves in almost every aspect of life, and astronomy is no different. An astronomer explains the history and future of AI in understanding the universe.
The central black hole of Messier 87, a massive galaxy in the Virgo cluster.

Beyond just looking at black holes, the next-generation Event Horizon Telescope collaboration is the first to bring together perspectives from across the sciences and humanities.
Radio observatories like the Green Bank Telescope are in radio quiet zones that protect them from interference.

Many telescopes use the radio spectrum to learn about the cosmos. Just as human development leads to more light pollution, increasing numbers of satellites are leading to more radio interference.
Black holes can have a mass equivalent to that of millions of suns. Other, smaller, black holes can combine the mass of Mount Everest into the size of an atom.
While we can’t see inside a black hole, we can spot the intensely bright glowing disc that surrounds one. Now, we might better understand why these discs appear to ‘twinkle’.
