Parker Solar Probe

NASA's Parker Solar Probe spacecraft kicked off the new year with another close approach to the sun on Sunday (Jan. 17) as the sun's activity picks up from a lull when the probe launched.

A NASA probe has peered into the sun's atmosphere and found 'bombs' of plasma, jets that affect solar wind and nanoflares that rapidly accelerate particles.

A daring sun-grazing NASA spacecraft turns its focus to Venus today (July 10) with a critical flyby that will pass through the planet's weird "tail."

NASA's daring Parker Solar Probe made its fifth daring flyby of the sun this weekend.

NASA's sun-grazing spacecraft is gathering the most data ever on its upcoming skim past our star, with instruments turned on for nearly two months.

It's always sunny for heliophysicists, but especially so now.

Solar scientists were excited that NASA would be launching a probe to fly closer to the sun than ever before, but they may not have bargained on already producing dozens of papers based on the data.

Coronal mass ejections aren't known for being subtle: Each such event can fling huge amounts of the soup of charged particles called plasma off the sun and out into the solar system.
