A new trove of free-floating planets, smaller and paired up more than expected, challenges stellar and planet formation models.
Lumps of dust are spiraling around a young star 5,000 light-years away. They could be Jupiter-like planets in the making.
Magnetic interactions between stellar wind and the planet likely caused extrasolar space weather.
A new study finds that the intersection between a searing dayside and a freezing nightside could be habitable.
The presence of complex organic molecules such as methanol, ethanol, and acetaldehyde in a molecular cloud suggests that these and simpler ices might be available to planetary systems right from the start.
Kepler’s first exoplanet is migrating toward its star, an evolved subgiant that is much bigger than first thought.
New simulations show that planets around young, massive stars may have been captured or stolen rather than homegrown.
Helioseismology allows scientists to study the interior of the Sun, solve some basic physics mysteries, and forecast space weather.
A new survey of hundreds of pulsars could help solve the mystery of why planets exist around these dead stars.
Coronal mass ejections from stars have eluded easy observation, so scientists are looking at what’s left behind.
