Saturn’s Ring System, Hyperion and Titan May Have Originated in Collision of Two Proto-Moons

Scientists argue that two Saturnian moons, Titan and Hyperion, are not primordial worlds, but the result of a dramatic merger between two ancient moons. 

NASA says organics on Mars are hard to explain without life

The researchers found that additional studies of the data from Curiosity show that non-biological sources they had considered don’t fully explain the organics. They conclude, therefore, that a biological source is a reasonable hypothesis.

Earth's Largest Reserve of Hydrogen Could Be Hiding in Its Core

Vast amounts of hydrogen could also be locked away in our planet's core, attached to the densely packed alloyed iron that lurks therein

Mysterious State of Matter Discovered Flowing Inside Earth's Core

By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird part-solid, part-liquid-like state thought to exist inside Earth's inner core is indeed possible.

Saturn’s biggest moon might not have an ocean after all

Careful reanalysis of data from more than a decade ago indicates that Saturn’s biggest moon, Titan, does not have a vast ocean beneath its icy surface, as suggested previously.

Uranus and Neptune may not be the icy worlds

A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by water-rich ices.

Tiny Meteoroids Poses 'Silent Threat' to Future Moon Base

The Moon has no atmosphere, yet it faces an invisible bombardment more relentless than any terrestrial storm, a constant rain of micrometeoroids, tiny fragments of rock and metal traveling at speeds up to 70 kilometers per second.

A Small World in the Outer Solar System Might Be Forming Rings

Astronomers found evidence of three rings around Chiron, which orbits the Sun between Uranus and Saturn.

Saturn’s Moon Shows Major Signs of Life

Astronomers have found that Saturn’s moon, Enceladus, is spewing out copious amounts of complex organic molecules, suggesting it’s an even more promising place to look for extraterrestrial life than previously thought.

Could a primordial black hole’s last burst explain a mysteriously energetic neutrino?

If a new proposal by MIT physicists bears out, the recent detection of a record-setting neutrino could be the first evidence of elusive Hawking radiation.

Webb Detects Complex Structures in Upper Atmosphere of Saturn

Astronomers using the NASA/ESA James Webb Space Telescope have detected a series of dark, bead-like and asymmetric star-shaped features in the ionosphere and stratosphere of Saturn.

NASA Says Mars Rover Discovered Potential Biosignature

A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. 

Scientists uncover hidden shards of Mars’ violent birth, frozen for billions of years

Mars isn’t the neatly layered world we once imagined — its mantle is filled with ancient, jagged fragments left over from colossal impacts billions of years ago. 

NASA’s Bennu Samples Reveal Complex Origins

Asteroid Bennu, sampled by NASA’s OSIRIS-REx mission in 2020, is a mixture of dust that formed in our solar system, organic matter from interstellar space, and pre-solar system stardust. 

New Moon Discovered Orbiting Uranus

Using NASA’s James Webb Space Telescope, a team has identified a previously unknown moon orbiting Uranus, expanding the planet’s known satellite family to 29.
