Helium that was once part of the atmosphere of the extrasolar planet HAT-P-32b is being ripped away and forming two giant streamers of gas several million kilometers long.
A new study finds that the intersection between a searing dayside and a freezing nightside could be habitable.
Interactions between lunar gravity and the terrestrial magnetic field may cause a 90° offset from the Moon’s position in its orbit.
Researchers used ice core data to reconstruct seasonal temperatures throughout the Holocene. The results link especially hot summers with patterns in Earth’s orbit.
In solar systems beyond our own, some moons might eventually collide with their host planets, new simulations suggest.
The dwarf planet’s ring makes astronomers question whether a long-held theory about ring and moon formation needs tweaking.
A cloud of dust traces the innermost planet’s orbital path. By all accounts, it shouldn’t be there.
Kepler’s first exoplanet is migrating toward its star, an evolved subgiant that is much bigger than first thought.
The mission, focused on the Didymos-Dimorphos binary asteroid system, proved that an asteroid’s orbit can be altered by kinetic impactor technology.
The military is launching a fleet of small, interconnected satellites to collect data, track missiles, and aim weapons.
