One of the Milky Way’s smallest galactic neighbours seems to have a supermassive black hole at its centre, upending ...

For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287.

An unexpected monster black hole was found hiding inside one of the Milky Way's tiniest neighbors, rewriting what scientists ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object ...

New simulations suggest dark matter could explain the mysterious gamma-ray glow at the Milky Way’s center. The findings show that the galaxy’s early mergers may have shaped dark matter in a way that ...

By zeroing in on the infrared scale, researchers offer details of the black hole jet stream in faraway galaxy M87.

The telescope captured the clearest image of the M87 galaxy's supermassive black hole and the ejecting material jet using an ...

A century after astronomers first spotted the colossal jet blasting from the black hole at the heart of the galaxy M87, a new look has brought it into startling focus. Using infrared observations, ...

A section that seats about 100 people just behind the south end zone at California’s Memorial Stadium has been painted black, hoping people with painted faces and other distinctive gear show up to add ...

A galaxy 2.5 million light-years away can be seen in Massachusetts. The best times to see the Andromeda Galaxy might be in late September and early October. This is when the Andromeda galaxy can be ...

More than a century ago, astronomer Heber Curtis spotted the first black hole jet – a vast stream of superheated plasma from the supermassive behemoth that sits at the centre of galaxy M87. Now, the ...

Astronomers detected a black hole displaced nearly a kiloparsec from the center of a dwarf galaxy 230 million light-years away. Unlike most, it is actively feeding and producing radio jets, making it ...
