Powerful jets are launched from the most massive objects in our universe, but we don’t fully understand how. This measurement gets us a step closer to solving the mystery.
People have been looking up at the stars for thousands of years. Here’s where to start if you want to learn more about the night sky – from spotting easy-to-find constellations to using the best apps.
The universe is expanding faster than physicists would expect. To figure out what processes underlie this fast expansion rate, some researchers are first trying to rule out what processes can’t.
In September 2023, a NASA mission successfully brought samples of an asteroid down to Earth in a sealed capsule. Analysis of these samples may reveal information about the origins of the universe.
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.

A new hypothesis suggests that the universe may be twice as old as we had believed. Observations from the James Webb Space Telescope provide new information on the rate of the universe’s expansion.
Our Sun will likely go out quietly – but not all such stars do. A new radio detection of a supernova can help us better understand these cosmic cataclysms.
Different measures of the rate of the Universe’s expansion give different results – and a new measurement technique only makes matters more complicated.
