Astronomers see the astrosphere of a sunlike star for the first time
Finding a bubble of hot gas blown by the stellar wind from a young star gives researchers a peek at what our sun was like when it was young.
- Space
A spacecraft duo will fly in formation to create artificial solar eclipses
ESA’s Proba-3 mission will use one satellite to block out the sun for another satellite, bringing the sun’s middle corona into new focus.
- Planetary Science
Mars’ potato-shaped moons could be the remains of a shredded asteroid
Phobos and Deimos could have formed from asteroid debris, a new study suggests. An upcoming sample return mission will help test the idea.
- Planetary Science
A first look at rocks from the lunar farside create a volcanic mystery
Rocks returned by China’s Chang’e-6 mission suggest volcanic activity just 2.8 billion years ago but lack telltale heat-generating elements.
- Planetary Science
Uranus may have looked weird when NASA’s Voyager 2 flew by
A solar wind event days before the NASA probe flyby in 1986 may have compressed the planet’s magnetosphere, making it look odder than it usually is.

A cosmic census triples the known number of black holes in dwarf galaxies
The DESI survey reveals that active black holes in small galaxies are common. The findings may help reveal how the two cosmic bodies evolve together.
- Astronomy
A zombie star’s spiky filaments shed light on a 12th century supernova
A 3-D map of the strange remains of a supernova seen in 1181 traces the odd tendrils of gas that jut out for several light-years in all directions.
