Astronomers have observed three types of black holes in the universe. Stellar-mass black holes formed from the collapse of a ...

A passing star may have kicked the weird moons of giant planets like Jupiter and Saturn into place, new research suggests.

This effect is responsible for the rotational motion we observe in celestial bodies. Edward Gomez likens the formation of our ...

"If there are lots of black holes out there, some of them must surely pass through our backyard every now and then." ...

Scientists say microscopic black holes could explain the elusive "dark matter" that makes up a quarter of all matter in the ...

A star’s flyby likely altered the orbits of trans-Neptunian objects beyond Neptune that changes how we view the solar ...

For years, astronomers have been hunting for Planet Nine, a hypothetical giant planet believed to be lurking at the far ...

"Primordial black holes do not live in the solar system. Rather, they're streaming through the universe, doing their own thing," said researcher Sarah Geller.

Astronomers capture images of star R Doradus, revealing giant gas bubbles and offering insights into stellar convection.

Gas bubbles on the surface of a star have been observed for the first time in detail outside our solar system, and they are ...

Using the Subaru Telescope, astronomers have identified previously unknown celestial bodies in the outer Solar System, ...

The universe might be teeming with microscopic black holes the size of an atom but with the mass of a city-sized asteroid, scientists say.
