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.

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.

Magnetic fields may supercharge the sun’s release of heat
Astronomers have linked flame-like tendrils rising from the sun to changes in its magnetic fields. This may be one step toward understanding why the sun’s corona is so very, very hot.

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.

Juno’s knocking on Jupiter’s door
The Juno spacecraft will peer into Jupiter’s clouds and fly in close to its monstrous auroras.

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.
