NASA-funded scientists have discovered shaded locations within pits on the Moon that always hover around a comfortable 63 F.

Neptune and Uranus have much in common yet their appearances are notably different. Astronomers now have an explanation for why the two planets are different colors.

The average global temperature on Neptune unexpectedly fluctuated during a recent 17-year period, according to a new study.

Finding plumes at Europa is an exciting prospect, but scientists warn it’ll be tricky, even from up close.

NASA’s Hubble Space Telescope has completed this year's grand tour of the outer solar system.

NASA Administrator Bill Nelson laid out the path forward for early Artemis missions that will pave the way for lunar surface missions.

A study shows how the chemicals in an exoplanet’s atmosphere can reveal whether the temperature on its surface is too hot for liquid water.

JPL's lucky peanuts are an unofficial tradition at big mission events.

In 2023, NASA’s Volatiles Investigating Polar Exploration Rover (VIPER) will land near the western edge of the Nobile Crater at the Moon’s South Pole.

The rover will be delivered to the Moon's surface in late 2023. VIPER is the first resource-mapping mission on the surface of another celestial body.

The Next Full Moon is the Harvest Moon, the Fruit Moon, the Barley Moon, and the Corn Moon.

The shadows cast by the roughness of the Moon’s surface create small cold spots for water ice to accumulate even during the harsh lunar daytime.

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.

NASA has selected SpaceX to provide launch services for Earth’s first mission to conduct detailed investigations of Jupiter's moon Europa.

A technique for scanning Mars rocks for microscopic fossils is also being developed to hunt for microbes on Enceladus, Titan, and Europa.

A proposed mission called Io Volcano Observer (IVO) would visit Jupiter’s moon Io, which is a true volcanic wonderland.

Phobos orbits through a stream of charged atoms and molecules that flow off the atmosphere of Mars, new research shows.

Astronomers using Hubble watched a mysterious dark vortex on Neptune abruptly steer away from a likely death on the giant blue planet.

NASA’s VIPER will be the first off-world rover to have its brains split in two as it explores the Moon’s surface in search of water ice.

For Artemis astronauts traveling to the Moon, two space weather instrument suites, NASA’s HERMES and ESA’s ERSA, will provide an early forecast.

Plumes of water vapor that may be venting into space from Jupiter's moon Europa could come from within the icy crust itself, according to new research.

New experiments re-create the environment of Europa and find that the icy moon shines, even on its nightside. The effect is more than just a cool visual.

NASA scientists have identified a molecule in Titan’s atmosphere that has never been detected in any other atmosphere.

Made of a pair of two-wheeled vehicles, DuAxel is designed to descend craters and near-vertical cliffs on the Moon, Mars, and beyond.

The next full Moon will peak after midnight on Wednesday morning, Sept. 2, 2020, The Moon will appear full for about three days around this time, from Monday evening through Thursday morning.
