We Finally Know How Long a Day on Saturn Is

By studying oscillations in the planet's iconic rings, researchers have determined it takes Saturn 10 hours, 33 minutes and 38 seconds to rotate once

The artist's concept depicts a comet-like tail of a possible disintegrating super Mercury-size planet candidate as it transits its parent star named KIC 12557548. At an orbital distance of only twice the diameter of its star, the surface temperature of the potential planet is estimated to be a sweltering 3,300 degrees Fahrenheit.

Disintegrating Planets Could Be the Key to Discovering What Worlds Are Made Of

Exoplanets that have been ripped apart by their host stars could provide an opportunity to measure the minerals of the galaxy

Planet Hunter TESS Is Already Spotting Hundreds of Crazy New Worlds

The first data from the space telescope's mission tallies more than 200 potential planets, including some just 50 light-years away

This image taken by the Long-Range Reconnaissance Imager (LORRI) is the most detailed of Ultima Thule returned so far by the New Horizons spacecraft. It was taken at 5:01 Universal Time on January 1, 2019, just 30 minutes before closest approach from a range of 18,000 miles (28,000 kilometers), with an original scale of 730 feet (140 meters) per pixel.

Behold the Most Distant Object Ever Visited by Spacecraft

The New Horizons spacecraft has transmitted images from its New Year’s Day approach back to Earth

Artist’s impression of NASA’s New Horizons spacecraft encountering 2014 MU69, a Kuiper Belt object that orbits one billion miles (1.6 billion kilometers) beyond Pluto, on Jan. 1, 2019. With public input, the team has selected the nickname “Ultima Thule” for the object, which will be the most primitive and most distant world ever explored by spacecraft.

Watch NASA Land the InSight Spacecraft on Mars

The InSight lander has successfully touched down on Mars

Once NASA's InSight lander touches down on the surface of Mars, it will use a seismometer to measure "Marsquakes," and a self-hammering heat probe will burrow five meters below the surface to study the internal heat of the planet.

NASA Will Attempt Its Eighth Mars Landing on Monday

Touching down on the surface of the Red Planet is one of the most difficult engineering challenges ever attempted, and InSight is about to give it a go

The planet, a frozen Super-Earth, orbits Bernard's Star about six light-years away

The color-enhanced image was created by citizen scientists Gerald Eichstädt and Seán Doran using data from the spacecraft's JunoCam imager, according to NASA.

Juno's Latest Photo of Jupiter Is Breathtaking

The image, processed from JunoCam's raw data, shows storms and winds in the planet's Northern Temperate Belt

Water found deep within the planet's interior contains different ratio of heavy hydrogen isotopes and normal hydrogen, pointing toward separate point of origin
