Using new data from NASA's Cassini spacecraft, researchers believe they have solved a longstanding mystery of solar system science: the length of a day on Saturn. It's 10 hours, 33 minutes and 38 seconds.


Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* (Sgr A*) at the center of our galaxy comes from a smaller region than previously thought.

The rings of Saturn may be iconic, but there was a time when the majestic gas giant existed without its distinctive halo.


The SpaceX Dragon cargo craft begins its departure from the International Space Station moments after being released from the grips of the Canadarm2 robotic arm.


This analysis confirms the existence of a jet emerging from the nucleus of the star, producing the GRB, and adds a new component to the picture


The NASA/ESA Hubble Space Telescope has discovered the brightest quasar ever seen in the early Universe.


This movie shows the propeller-like rotation of Ultima Thule in the seven hours between 20:00 UT (3 p.m. ET) on Dec. 31, 2018, and 05:01 UT (12:01 a.m.) on Jan. 1, 2019, as seen by the Long Range Reconnaissance Imager (LORRI) aboard NASA's New Horizons as the spacecraft sped toward its close encounter with the Kuiper Belt object at 05:33 UT (12:33 a.m. ET) on Jan. 1.


A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to the explosive release of energy in a brilliant flash.


Saturn's moon Titan is enveloped in a thick atmosphere, but through the infrared eyes of the international Cassini mission, the moon's myriad surface features are revealed in this exquisite global mosaic.


South Africa's Western Cape often falls victim to fires during the dry hot summer months.


New research led by an astronomer at the University of Warwick has found the first confirmed example of a double star system that has flipped its surrounding disk to a position that leaps over the orbital plane of those stars.


A panorama taken by the Chang'e-4 lander of itself, the Yutu-2 rover, and the surrounding lunar terrain on the far side of the Moon has been released.


A Japanese research group has identified a giant streak structure among the clouds covering planet Venus based on observation from the spacecraft Akatsuki.


This Proba-V view shows all that is left of the Aral Sea, once one of the four largest lakes in the world and now one of the world's major ecological disaster areas. It has shrunk into separate lakes, surrounded by Earth's youngest desert.


A Canadian-led team of scientists has found the second repeating fast radio burst (FRB) ever recorded.


It looks like something out of a science fiction movie but it's reality. SpaceX has released a series of images for its upcoming, and first, Crew Dragon spacecraft mission as it was moved to the launchpad.


Scientists have charted the environment surrounding a stellar-mass black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station.


In a new Caltech-led study, researchers from campus and the Jet Propulsion Laboratory (JPL) have analyzed pulses of radio waves coming from a magnetar -- a rotating, dense, dead star with a strong magnetic field -- that is located near the supermassive black hole at the heart of the Milky Way galaxy.


Data captured by ESA's galaxy-mapping spacecraft Gaia has revealed for the first time how white dwarfs, the dead remnants of stars like our Sun, turn into solid spheres as the hot gas inside them cools down.


When ESA's planned Hera mission journeys to its target binary asteroid system, it will not be alone.


Astronomers have found a new exoplanet that could alter the standing theory of planet formation. With a mass that's between that of Neptune and Saturn, and its location beyond the "snow line" of its host star, an alien world of this scale was supposed to be rare.


Astronomers from the Sloan Digital Sky Survey (SDSS) have announced that they have developed a new tool to find otherwise-hidden galaxy mergers in data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey of SDSS.


NASA's Transiting Exoplanet Survey Satellite (TESS) has found three confirmed exoplanets, or worlds beyond our solar system, in its first three months of observations.


Sayram Lake is pictured in northwest China near the border with Kazakhstan as the International Space Station orbited 253 miles above the Asian continent.


NASA's Transiting Exoplanet Survey Satellite, TESS, has discovered a third small planet outside our solar system, scientists announced this week at the annual American Astronomical Society winter meeting in Seattle.


NASA's Hubble Space Telescope brings the vastness of space into perspective in this mosaic image of the Triangulum galaxy (M33), our neighbor in a collection of dozens of galaxies called the Local Group.


An Expedition 57 crew member photographed the desert coast of Mauritania on the Atlantic Ocean near the border with Western Sahara on the African continent.


Fresh food is so attractive to astronauts that they toasted with salad when they were able to cultivate a few lettuce heads on the International Space Station three years ago.


There are more than 3,900 confirmed planets beyond our solar system. Most of them have been detected because of their "transits" -- instances when a planet crosses its star, momentarily blocking its light.


New research led by astrophysicists at Durham University, UK, predicts that the Large Magellanic Cloud (LMC) could hit the Milky Way in two billion years' time.


The Senegal River valley that marks the border between the Atlantic coast nations of Senegal and Mauritania is pictured as the International Space Station orbited 252 miles above the African continent.


Scientists have found evidence that dark matter can be heated up and moved around, as a result of star formation in galaxies.


Data from NASA's New Horizons spacecraft, which explored Kuiper Belt object Ultima Thule earlier this week, is yielding scientific discoveries daily.
