New study counters idea that Jupiter’s mysterious core was formed by a giant impact

A new Durham University study has found that a giant impact may not be responsible for the formation of Jupiter’s remarkable “dilute” core, challenging a theory about the planet’s history.

Secretive mini space shuttle set for Space Coast launch; late-night sonic boom possible

It won’t have any crew, but the U.S. Space Force is set to send the Boeing-built X-37B spacecraft—which looks like a miniature space shuttle—back for a long-duration mission to orbit during a late-night launch Thursday.

The stunning astrogeology of the Apollo missions

Neil Armstrong almost made a mistake. He had found an interesting rock sticking out of a formation. Curious to see what the rock was made of, he needed to examine its interior more closely. So he reached for his hammer and took a swing. The rock was far more brittle than he anticipated, and instead […]

Dark matter in gas giants could collapse into detectable black holes, model suggests

More than 5,000 planets have been discovered beyond our solar system, allowing scientists to explore planetary evolution and consider the possibility of extraterrestrial life. Now, a UC Riverside study published in Physical Review D suggests that exoplanets, which are planets orbiting stars outside our solar system, could also serve as tools to investigate dark matter. […]

How NASA’s Artemis II lunar science operations will inform future missions

NASA’s Artemis II mission, set to send four astronauts on a nearly 10-day mission around the moon and back, will advance the agency’s goal to land astronauts at the moon’s south polar region and will help set the stage for future crewed Mars missions.

Brightest-ever fast radio burst allows researchers to identify its origin

An international team of astronomers has observed one of the brightest fast radio bursts (FRBs) ever detected—and pinpointed its location in a nearby galaxy (NGC 4141). FRB 20250316A has been nicknamed RBFLOAT, which stands for Radio Brightest FLash Of All Time. The finding and the discovery of the location surprised the team and revealed new […]

Black holes may be the engines driving the universe’s dark energy

Researchers at Durham and collaborators in the Dark Energy Spectroscopic Instrument (DESI) mission have proposed a bold new theory that black holes could be converting matter into dark energy.

Close-up images reveal asteroid debris plume after DART impact

On Sept. 11, 2022, engineers at a flight control center in Turin, Italy, sent a radio signal into deep space. Its destination was NASA’s DART (Double Asteroid Redirection Test) spacecraft flying toward an asteroid more than 5 million miles away.

What happened before the Big Bang? Computational method may provide answers

We’re often told it is “unscientific” or “meaningless” to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King’s College London, UK, and astrophysicists Katy Clough, of Queen Mary University of London, UK, and Josu Aurrekoetxea, at Oxford University, UK, published in Living Reviews in Relativity, proposes […]

Spacecraft design gets a boost with new origami flower-like patterns

The ancient Japanese art of paper-folding, or origami, is already inspiring the design of the next generation of space vehicles, but now there’s a new family of origami shapes that could make them even more compact and reliable.

Analysis suggests the most likely places to detect signals from an extraterrestrial intelligence

If an extraterrestrial intelligence were looking for signs of human communications, when and where should they look? In a new study, researchers at Penn State and NASA’s Jet Propulsion Laboratory in Southern California analyzed when and where human deep space transmissions would be most detectable by an observer outside our solar system and suggest that […]

XRISM reveals slow-moving hot gas near black hole during faint X-ray phase

An international research team has reported remarkable findings from an XRISM observation of the black hole X-ray binary 4U 1630–472, located in our galaxy. XRISM is an X-ray astronomy satellite developed by Japan in collaboration with the United States and Europe and was launched from the Tanegashima Space Center on September 7, 2023.

Astronomers combine X-ray and radio data to map pulsar ‘hand’ nebula

In 2009, NASA’s Chandra X-ray Observatory released a captivating image: a pulsar and its surrounding nebula that is shaped like a hand. Since then, astronomers have used Chandra and other telescopes to continue to observe this object. Now, new radio data from the Australia Telescope Compact Array (ATCA) has been combined with Chandra’s X-ray data […]

Ceres may have had long-standing energy to fuel habitability

New NASA research has found that Ceres may have had a lasting source of chemical energy: the right types of molecules needed to fuel some microbial metabolisms. Although there is no evidence that microorganisms ever existed on Ceres, the finding supports theories that this intriguing dwarf planet, which is the largest body in the main […]
