Black hole mega-burp was truly explosive
Long, long ago, in a galaxy far, far away, a black hole blasted out 100 billion times as much energy as our sun ever will. One word for that: Wow!

This ‘Sombrero’ stole a big galaxy
The Sombrero Galaxy is an odd spiral galaxy that outshines all others within 35 million light-years of Earth. Its bright, iron-rich halo suggests it consumed one or more large galaxies.

Glass beads help scientists puzzle out how baby planets grow
Researchers have mimicked the first stages of planet formation in the lab. All they needed were glass beads and a catapult.

NASA’s Parker probe spots rogue waves and magnetic islands on the sun
The Parker probe’s first data is giving scientists a look at what’s to come as the craft moves closer to the sun over the next few years.

Dust-shrouded monster is a snapshot from the early universe
Scientists have spotted a massive galaxy from the early universe shrouded in dust. It turned up in a small survey by the ALMA radio telescopes in Chile.

Explainer: Understanding meteors and meteor showers
Meteors regularly enter Earth’s atmosphere. Most ‘shooting stars’ pose few risks to life on the ground, but the rare big ones can be lethal.

Explainer: What are black holes?
Among the most extreme celestial bodies in the universe, black holes are dense, massive entities whose gravity can sometimes hold together an entire galaxy.

Asteroids may have delivered water to early Earth
Scientists shot mineral pellets at a simulated planet. It showed an impact wouldn’t have boiled off all of an asteroid’s water.

Small, distant worlds are either big Earths or little Neptunes
The Kepler space telescope data are in. They split Earth-like exoplanets into two groups and reveal 10 new rocky planets in the ‘Goldilocks’ zone.

Jupiter may be the solar system’s oldest planet
Jupiter’s early existence may explain the odd arrangement of planets in the solar system, a new study suggests.

Gravitational waves detected yet again
For the third time in 16 months, scientists have announced detection of gravitational waves washing over the spacetime environment in which Earth resides. This seems to show that such waves may not be rare.
