Astronomers found a new moon orbiting Uranus, as well as two around Neptune. The tiny satellites appeared as faint specks in the outer reaches of the solar system following hours of ground-based observations.
While journeying through the far reaches of the solar system, the New Horizons probe picked up a dusty trail of icy fragments that may indicate that the Kuiper Belt—home to former planet Pluto and countless other objects—is way bigger than we thought.
An odd little moon that orbits closely to Saturn just revealed its biggest mystery: a hidden ocean that lies beneath its heavily cratered surface.
A previously unknown satellite may be shaping the rings of Chariklo, a petite body that orbits the Sun between the orbits of Saturn and Uranus, according to a team of astronomers that recently simulated the rings’ dynamics.
Do not scratch your eyes: the Moon is slowly shrinking, causing quakes on its surface that complicate NASA’s plans for landing Artemis 3, the first Artemis mission that will make a crewed landing on the Moon, and more ambitious missions geared towards maintaining a prolonged human lunar presence.
There are jets in Jupiter’s magnetosheath, according to Voyager 2 mission data from 1979. The 45-year-old information is now revealing the dynamics of the plasma stream.
The Webb Space Telescope has spotted something weird: a brown dwarf with what appear to be aurorae, what we Earthlings sometimes call the Northern Lights. What makes the observation particularly surprising is that the brown dwarf doesn’t have a nearby star that could cause such an aurora.
A strong geomagnetic storm will hit Earth tonight following a significant solar flare that occurred on Tuesday, NOAA’s Space Weather Prediction Center reported today.
Exoplanets pushing their atmospheres away may explain a gap in exoplanet masses, according to a team of researchers that recently studied data from NASA’s retired Kepler Space Telescope.
