A meteorite impact may have once rained gold on Western Australia

We’re used to a lot of different natural things falling out of the sky. These can include snow, rain and sometimes even frogs (yes, really). All of these relate to weather phenomena.

Where not to look in the search for ET

There’s a question at the heart of SETI that doesn’t get nearly enough attention. It isn’t whether aliens exist, and it isn’t whether we have the technology to detect them. It’s a far more practical problem: With a billion stars in our galaxy and finite telescope time, how do you decide which ones to actually […]

Astronomers find a four-carbon sugar in deep space

The space between stars may seem like a barren desert, but over the past few decades scientists have been finding all sorts of interesting chemicals in it. From the precursors to proteins to the building blocks of cell membranes, there has been discovery after discovery of new molecules in the giant gas clouds between the […]

Galaxy-killing wind discovered in the early universe

Astronomers have discovered a “galaxy-killing wind” that may explain why there are far more massive “dead” galaxies than expected in the early universe. This wind, powered by cosmic collisions between galaxies, could quickly blow away all the fuel for new stars, leaving a galaxy on the brink of death and helping to solve one of […]

Italian astronaut to pilot Artemis III mission

Italian astronaut Luca Parmitano is hoping to bring a taste of his homeland to the Artemis III mission, which he will pilot near Earth in 2027 to test two lunar modules.

JWST reveals dawn-dusk atmosphere split on ultra-hot exoplanet WASP-121 b

Astronomers have revealed distinct differences in atmospheric conditions between the morning and evening transition zones of the ultra-hot gas planet WASP-121 b, which separate day from night, commonly called terminators. This achievement was only possible due to the unmatched sensitivity of the James Webb Space Telescope (JWST).

Dino-killing asteroid may have fueled underground life for 8 million years

The asteroid that caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer than previously suspected.

SpaceX’s hold over orbit matches East India Company’s grip on maritime trade

Elon Musk’s SpaceX holds sway over the emerging space economy in a way that has more in common with notorious colonial-era trading companies than the competitive markets of today’s textbooks, according to a new study.

MeerKAT reveals three electron acceleration sites in one solar flare

Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating and bulk plasma motions on short timescales. Core questions during solar flares remain unresolved, including how and where particle acceleration occurs, and how energized electrons propagate through coronal magnetic structures.

Italian Luca Parmitano to be first European to join an Artemis mission: NASA

Luca Parmitano, an Italian astronaut, will be the pilot of NASA’s Artemis 3 mission, the first European to join one of the program’s missions, the U.S. space agency announced Tuesday.

Possible dark matter-deficient twins discovered in the Fornax Cluster

Astronomers have identified a possible new example of one of the universe’s strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair, FCC 224 and FCC 240, on the outskirts of the Fornax Cluster, share several unusual traits with the only known pair of controversial dark-matter-deficient galaxies. The […]

Space telescopes are now overwhelmed by satellite trails

Unfortunately, there’s more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA’s Ames Research Center, reports that 73.3% of images the agency’s new SPHEREx space telescope collected between May and September of last year were contaminated by at least one artificial satellite […]

Artemis II moon mission research continues on Earth

Since NASA’s Artemis II crew members safely splashed down in the Pacific Ocean on April 10 after their record-setting mission around the moon, science teams have been busy collecting more data and combing through observations collected on the test flight. Results from these science investigations will help support safe human exploration of deep space and […]

NASA’s INCUS mission on road to launch, study storms from space

Teams working on NASA’s INCUS (Investigation of Convective Updrafts) mission, the first space-based survey of the dynamics of tropical convective storms, have completed assembly and tested two of the mission’s small satellites, or SmallSats. Testing continues on the third SmallSat and is scheduled for completion no earlier than September ahead of a 2027 launch.
