The quasi-periodic eruptions of X-rays from a black hole 300 million light-years away are unlike any researchers have ever ...

Webb witnessed a highly ionised gas whose level of energy was too high to come from something like supernovae, making ...

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and slowly ...

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

A blob of gas seen outside the Milky Way could be a type of starless, dark matter–dominated galaxy. Some scientists are skeptical.

A massive black hole at the heart of a galaxy in the Virgo constellation is waking up, shooting out intense X-ray flares at ...

ALMA has revealed evidence of a new type of slim, filamentary structure that drives cycles of depletion and replenishment. At ...

The James Webb Space Telescope (JWST) has teamed up with the MeerKAT radio telescope array to explore how magnetic fields ...

Back when the Universe was new, following the Big Bang some 13.8 billion years ago, galaxies took a bit of time to assemble ...
