Black Holes

"This was many times more energetic than any similar event and more than any known explosion powered by the collapse of a star."

2025 was another big year for black holes, and here's our pick of the top black hole stories from the last twelve months.

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar explosion — or any other type of normal stellar explosion."

"The forces that are needed to dislodge such a massive black hole from its home are enormous."

"This is a real gift for physicists as we confirm predictions made more than a century ago."

"This is certainly an outburst unlike any other we've seen in the past 50 years."

In other words, the matter traveled at 20% the speed of light.

"The sizes of these radio jets are not comparable to our solar system or even our galaxy."

NASA's exoplanet-hunting spacecraft TESS has heard the song a star-quaking red giant sings to its partner black hole.
