The solar system is moving through space over three times as fast as estimated, calling into question our best model of the universe and its evolution.

Scientists may have solved the mystery of an "impossible" merger between two black holes so massive and fast-spinning that they shouldn't even exist, according to current theory.

"Astronomers have wanted to spot a coronal mass ejection on another star for decades. We’ve now managed to do this for the first time."

"This study changes how we see the Pleiades — not just seven bright stars, but thousands of long-lost siblings scattered across the whole sky."

"We expected to see this effect, but we were still surprised by just how efficient these stars seem to be at engulfing their close planets."

NASA's Juno spacecraft has revealed that the solar system's most volcanic body is even hotter than scientists thought.

"If these results are confirmed, it would mark a major paradigm shift in cosmology since the discovery of dark energy 27 years ago."

"By reproducing relativistic plasma conditions in the lab, we can measure processes that shape the evolution of cosmic jets and better understand the origin of magnetic fields in intergalactic space."

"The James Webb Space Telescope has opened a new frontier in extragalactic astrophysics, revealing objects we didn't even suspect existed, and we're only at the beginning of this adventure."

"If such a fifth force exists, it cannot exceed 7% of the strength of gravity."

Astronomers have detected the most distant and biggest black hole flare ever seen, the result of a black hole ripping apart and devouring a star 30 times as massive as the sun.

"The reason for 3I’s rapid brightening, which far exceeds the brightening rate of most Oort cloud comets at similar distances, remains unclear."

Scientists are searching for answers in the cosmic mystery of ghost particles known as neutrinos.

"Our scenario describes all the evolutionary phases of the supernova with great precision."

Gravitational wave detectors on Earth have heard the "cry" of two newborn black holes with some unusual and remarkable properties.

Using NASA's TESS exoplanet hunter, astronomers have discovered a strange arrangement of exoplanets around tight binary stars that shouldn't be.

A new program has discovered chaos in a nearby planetary system, which could explain the existence of a phenomenon astronomers call the hot-Neptunian desert.

Mysteriously powerful cosmic winds around neutron star may be 'game-changer' for understanding monster black holes

"The speed at which this doomed stellar system is lurching wildly, likely due to the extreme brightness, is a frantic sign of its imminent, violent end."

A new emulator is tackling the near-impossible task of mapping the universe's large-scale structure without sacrificing intricate details.

Newly released images of the supermassive black hole at the heart of the galaxy M87 show that the plasma that swirls around it has unexpectedly reversed directions.

The mystery of the James Webb Space Telescope's "little red dots" could be solved if they are not ancient galaxies but are entirely new celestial objects called "black hole stars."

The first-ever detection of gravitational waves was made 10 years ago today (Sept. 14). In celebration, Space.com takes you through the most significant gravitational wave discoveries to date.

Everything about the Infinity Galaxy, recently discovered by the JWST, is strange. One odd feature could be the first evidence of a "direct collapse" black hole.
