Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely ...

Scientists have discovered something unprecedented near the black hole M87*: its magnetic field has flipped direction between 2017 and 2021.

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

Could black holes help explain the origins of high-energy cosmic radiation? The universe is filled with many forms of radiation and particles that can be detected here on Earth. Among them are photons ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...

“Without this dynamic process, stars would not form, and planets and even humankind would not exist,” explained Ji, one of the lead researchers on the project and a principal investigator at PPPL. “It ...

The magnetic fields are more than a thousand times stronger than the magnetic field used in MRI machines. Multiple victims reported in shooting at Michigan church, suspect is "down," authorities say ...

M87* is a supermassive black hole in a galaxy 55 million light-years away with a mass around 6.5 billion times the mass of the Sun. As the first subject of the Event Horizon collaboration's mission to ...

Strangely sharp circles of radio waves in space have puzzled astronomers since their surprise discovery in 2019. Now, a team has analyzed one closely in hopes that it might give up its secrets. Firing ...

A series of observations between 2017 and 2021 suggest the supermassive structure’s magnetized plasma is more dynamic than thought ...

One of the first black holes ever imaged, M87*, located at the heart of the Messier 87 galaxy 55 million light-years from Earth, continues to surprise astronomers with its behavior. New ...

Astronomy has a way of surprising you. When you believe the universe has yielded its biggest secrets, distant giants and faint signals come along to pose even more questions. Two recent discoveries ...
