Electric charges on dust grains may help explain how planets are born
In an experiment, glass beads clung together like protoplanetary dust particles when shaken and flung more than 100 meters skyward.

Physics Nobel awarded for discoveries about the universe’s evolution and exoplanets
Three scientists share the 2019 Nobel Prize in physics for revealing what makes up our cosmos and for finding the first planet orbiting a sunlike star.
- Space
Why just being in the habitable zone doesn’t make exoplanets livable
A reignited debate over whether a new planet is habitable highlights the difficult science of seeking alien life.
- Space
‘Imagined Life’ envisions the odd critters of other planets
The authors of ‘Imagined Life’ rely on science to sketch out what kind of organisms might exist on exoplanets.
- Space
A supermassive black hole shredded a star and was caught in the act
Astronomers have gotten the earliest glimpse yet of a black hole ripping up a star, a process known as a tidal disruption event.
- Astronomy
This may be the first known exoplanet with rain and clouds of water droplets
For the first time, astronomers have detected water vapor and possibly signs of clouds and even rain in the air of a potentially habitable exoplanet.
- Space
A proposed space telescope would use Earth’s atmosphere as a lens
One astronomer has a bold solution to the high cost of building big telescopes.
- Astronomy
TESS has found the first-ever ‘ultrahot Neptune’
NASA’s TESS telescope has spotted a world that could be a bridge between other types of exoplanets: hot Jupiters and scorched Earths.
- Astronomy
Stars may keep spinning fast, long into old age
NASA’s TESS telescope has spotted an old star that spins too fast for theory to explain, suggesting that stars may have a magnetic midlife crisis.
- Astronomy
Gaps in gas disks around stars may not always mark newborn planets
New research has prompted a rethink of the theory that gaps in planet-forming disks around young stars mark spaces where planets are being created.
- Astronomy
Moons that escape their planets could become ‘ploonets’
If giant planets in other star systems lose their moons, the freed objects could become “ploonets,” and current telescopes may be able to find them.
- Astronomy
A new algorithm finds nearby stars that could host hidden worlds
An algorithm dubbed “Netflix for exoplanets” identified more than 350 stars that, based on their chemistry, might have planets orbiting out of sight.
