NASA’s Parker probe reveals the sun’s rogue plasma waves and magnetic islands
Scientists have analyzed the Parker probe’s first data, giving a peek at what’s to come as the craft moves closer to the sun over the next few years.

How brightly the moon glows is a mystery, but maybe not for long
The best estimates for the moon’s brightness are still somewhat unsure. A new experiment is trying to fix that.

A newfound black hole in the Milky Way is weirdly heavy
A dark mass about 68 times as massive as the sun is locked in orbit with a star in our galaxy. Theory says that such black holes shouldn’t get so big.

19 more galaxies mysteriously missing dark matter have been found
The finding reveals a population of dwarf galaxies that defy common wisdom about how these star systems form and evolve.

How two gamma-ray bursts created record-breaking high-energy photons
Light packing up to 1 trillion electron volts of energy bolsters a theory for how these cosmic explosions produce such high-energy radiation.

Realigning magnetic fields may drive the sun’s spiky plasma tendrils
Solar spicules emerge near counterpointing magnetic fields, hinting that self-adjusting magnetism creates these filaments, which may heat the corona.

Light leaking from a distant galaxy hints at a cosmic makeover’s origins
Ultraviolet light slips through a hole in a distant galaxy’s gas. Older galaxies might have used the trick to ionize most of the universe’s hydrogen.

Voyager 2 reveals the dynamic, complex nature of the solar system’s edge
With two spacecraft outside the sun’s magnetic bubble, researchers get a new look at the boundary between the sun and its galactic environment.
