Gamma rays detected by NASA's Fermi spacecraft indicate that microquasars are powered by small black holes slowly devouring stars. They pack quite a punch, bombarding Earth with cosmic rays.

After the space community braced for a brutal shake-up at NASA this week, a last-minute decision on Tuesday (Feb. 18) spared over 1,000 agency employees on probationary status from being dismissed.

Using a revolutionary dark energy camera, astronomers have discovered the largest haul of "missing link" intermediate-mass black holes ever seen, but there should have been more.

The world's largest telescope continues to take shape on the Cerro Armazones mountain in Chile's Atacama Desert.

Not much, unless we're talking about spacecraft.

Resilience, a lunar lander built by Japanese company ispace, zoomed within a mere 5,220 miles (8,400 kilometers) of the moon on Feb. 14.

On the 95th anniversary of its discovery, Pluto remains one of the most beloved and enigmatic worlds in our solar system, whether you call it a planet or not.

Astronomers have discovered a powerful jet stream raging through the atmosphere of an ultra-hot Jupiter exoplanet ravaged by liquid iron rains.

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.
