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.

After 30 years, this supernova is still sharing secrets
It’s been 30 years since astronomers first witnessed the stellar explosion known as SN 1987A. Today, researchers are still learning from this cataclysmic phenomenon.

Scientists Say: Supernova
When a star has too much mass, it can explode. The explosion is called a supernova.

Eclipses come in many forms
Eclipses are one of nature’s most awesome spectacles, and scientists have learned a lot by observing them and related celestial alignments — occultations and transits.

Star caught passing gas before exploding
Stars can become unstable as they near death, a new study suggests. Some may even spew gas for a year or so before they explode.

Rivers of stars flow between ‘clouds’ orbiting the Milky Way
Two streams of stars flow between dwarf galaxies known as the Magellanic Clouds. This new finding could give clues to the structure of our Milky Way galaxy.

A new, nonexplosive source of black holes?
At least one black hole may have formed from the collapse of a cloud of gas, which is not the usual birthing scheme. This might even be how some of the earliest gargantuan black holes developed.

Cool Jobs: Solar sleuthing
No star is closer than the sun, and yet there’s much science still don’t know about how it actually works. These scientists are helping solve the mysteries.

Pollution may give ‘first’ stars a youthful look
The oldest stars should be made of only light elements. But these suns may have sucked up heavier elements, giving them a more youthful appearance, a new study finds.

News Brief: Latest supernova is also super-brightest
The light from stellar fireworks in a galaxy far, far away has just reached Earth. It comes from a star that exploded in a massively bright flash.

Mini-sats: The trick to spying Earth-bound asteroids?
NASA is supposed to begin nonstop screening by 2020 for all asteroids that could pose a threat to Earth. Some astronomers now think the only way to affordably meet that deadline is by using mini-satellites
