The universe may have started with a Big Bang, but it will most likely end in an utterly anticlimactic way, slowly fading to black over trillions and trillions of years. Now, a theoretical physicist ...

Smaller black holes tend to attract less material, making them naturally dimmer. Chandra would miss many of these faint ...

Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the ...

Astronomers know that most galaxies house supermassive black holes in their centers, from the largest galaxies down to small dwarfs. They also know that when supermassive black holes are actively ...

A scientist has crunched the numbers to estimate when the universe will "die," or fizzle out with no more star activity whatsoever. The last supernova will be a "black dwarf supernova" which will be ...

Scientists are hoping to find out how supermassive black holes with masses millions or billions of times larger than the sun came into being—and came across black holes "wandering" dwarf galaxies in ...

The last explosions to ever take place in the universe will be "black dwarf supernova," with these silent fireworks going off long after everything else has died, trillions upon trillions of years ...

Astronomers have just discovered the smallest known galaxy that harbors a huge, supermassive black hole at its core. The relatively nearby dwarf galaxy may house a supermassive black hole at its heart ...

The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass was ...

In a study based on new observations from the Chandra X-ray Observatory, NuSTAR and Australia Telescope Compact Array, a team of researchers may have confirmed the presence of a black hole and a white ...

A white dwarf is a solar-mass star at the end of its stellar evolutionary sequence — essentially the core of a star that began life less than eight times the Sun’s mass. Thermal emission is ...

A white dwarf is one of the last stages of life for stars of a certain size, and it's all downhill from there – with no new source of energy, the object will gradually fade away into obscurity. But ...
