Undergraduate student may have solved puzzle regarding isolated galaxies that have stopped producing stars

An undergraduate astrophysics student at UC Berkeley has found three unusual galaxies—cataloged as Shapiro Dwarf Galaxies I, II and III. Each galaxy is far from other galaxies and has stopped making stars, a combination that is extremely rare. The discovery, published in The Astrophysical Journal, provides compelling observational evidence of a long-held astronomical theory.

Radio galaxy from 12.5 billion years ago may be most powerful ever found

Astronomers have confirmed a powerful radio galaxy from nearly 12.5 billion years ago. The source, TXS 2354+015, was originally identified as a high-redshift candidate from its characteristic drop in optical light, and follow-up spectroscopy placed it at a redshift of 4.946. Their paper was posted to the arXiv preprint server on Sept. 23.

Alcohol in space: Exotic methanol discovered in planet-building zones

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory is a partner (NSF NRAO), has combined expertise from across the globe to open a new window on how the organic molecules that seed planets, and potentially life, form in space.

Mars’ oddest cloud may be even odder than previously thought

Scientists using the European Space Agency’s Mars Express, in combination with a state-of-the-art meteorological model of the Red Planet, have found that there may be some exotic physics behind Mars’ most curious cloud. The paper, “Homogeneous ice Nucleation from Water Vapour Suggested by Elongated Clouds on Mars,” is published in Nature Geoscience.

Computer scientist tracks satellites with automated observatory built from off-the-shelf technology

Allen Schnibben’s interest in space started when he was a child. “I picked up some books about the solar system when I was in elementary school. In middle school, I got a telescope and I started observing the night sky as a hobby,” said Schnibben, a computer scientist at Sandia National Laboratories. “My entire life, […]

Simulated moon soil and recyclable thermoplastics could help build future space infrastructure

Transporting material from Earth to the moon is an expensive proposition: By some estimates, moving a single kilogram (2.2 pounds) can cost more than $1 million. Any plan to build a permanent human habitat up there will depend on bringing that sky-high cost down.

NASA’s Curiosity rover catches stunning Martian dawn

A newly released panorama captured by NASA’s Curiosity rover offers the most detailed view yet of distant, wind-carved Martian cliffs, highlighting features the mission’s scientists have long been waiting to see up close. The scene was snapped at 8:30 a.m. local Mars time, showing striking blue hues in the foreground as bright morning light illuminates […]

Webb captures commotion from nebula’s stellar jets

The NASA/ESA/CSA James Webb Space Telescope has unveiled numerous stars formerly hidden by clouds of dust in a stellar nursery known as NGC 7129—a cauldron of cosmic creation, 3,300 light-years from Earth. Webb captured infrared light, which pierces through the dense matter that scatters or absorbs other types of light. This region, rife with stellar […]

A gamma-ray burst’s engine stayed active for nearly a month, breaking the previous record

Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the burst’s own rest frame—around 20 days longer than the previous record. The paper, posted to the arXiv preprint server on Sept. 18, explores different […]

Unusual stars may not owe their origins to hypernovae after all

Evidence for hypernovae, theorized to be the most powerful explosions in the universe, has been disputed in two papers by University College London (UCL) researchers.

Stem cells survive unexpectedly rough space travel

In early 2024, laboratory-grown neurospheres (i.e. clusters of neural stem cells) were sent to the International Space Station (ISS) to be exposed to microgravity. The return trip was delayed several times due to bad weather in the landing zone. As a result, the cells were outside controlled culture conditions for longer than anticipated—beyond the limit […]

Striking new images of unique supernova remnant reveal pearl-like chains

The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple times. Using the Gemini North telescope, an international team co-led by Ilaria Caiazzo, assistant professor at the Institute of Science […]

To keep GPS constellations from drifting, look to the moon

Global positioning systems are a key feature in everyday life for much of the world’s population. Whether it’s ensuring a ship delivers its goods safely or helping you avoid a road closure on your commute home, GPS can help.

Where are the best places for life in the cosmos? A universe in a supercomputer yields an answer

Earth seems like a troubled place right now, but at least our cosmic surroundings appear peaceful. This is not universally true, as explosions, collisions and other dangers lurk in other places and times.
