3I/ATLAS contains 30 times more semi-heavy water than comets in our solar system

New observations of the interstellar comet 3I/ATLAS include the first measurement of the abundance of deuterated water relative to ordinary water in an interstellar object. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered that the interstellar comet 3I/ATLAS is made of an astonishingly high ratio of semi-heavy water relative to water, indicating that its […]

Did NASA’s Curiosity rover find signs of ancient life on Mars? An astrobiologist explains how we determine ‘life’

NASA’s Curiosity rover has identified seven new organic compounds on the planet Mars, according to new research published in Nature Communications.

Mysterious gas clouds near Milky Way’s black hole now have a likely source

New observations and simulations by a team of researchers led by MPE reveal that a massive binary star near our galaxy’s center is responsible for creating a series of enigmatic gas clouds—compact gas clumps that help feed the supermassive black hole Sagittarius A*. The study is published in the journal Astronomy & Astrophysics.

Light-powered propulsion expands space exploration possibilities

Reaching the nearest star system, Alpha Centauri, would take hundreds of thousands of years using current rocket propulsion technology. Researchers in the J. Mike Walker ’66 Department of Mechanical Engineering at Texas A&M University have demonstrated a new approach to light-driven motion, showing that lasers can be used to lift and steer objects in multiple […]

Astronomers reveal spectacular birthplace of cosmic buckyballs

Fifteen years after Western astronomers first discovered “buckyballs” in space (soccer ball-shaped molecules that resemble a hollow sphere), they’re back with stunning images and rich data generated using the James Webb Space Telescope (JWST)—the most powerful space telescope ever built. The team led by Jan Cami, a physics and astronomy professor, first detected buckyballs using […]

Ames’s contributions to Artemis II

NASA successfully sent four astronauts around the moon for the first time in more than 50 years, setting the stage for future lunar landing missions. As the agency continues to push the bounds of space exploration, NASA’s Ames Research Center in California’s Silicon Valley provided essential support in preparing for the mission.

Astronomers find an exo-Jupiter, and it seems to have clouds

A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: water-ice clouds on a distant Jupiter-like exoplanet called Epsilon Indi Ab.

Sulfur-rich Mercury magmas behave differently than Earth’s do

Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It is also reduced, a chemical state in which the substances have gained electrons. In fact, it’s the most reduced planet […]

These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star

Luminous fast blue optical transients (LFBOTs) are among the universe’s brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering two important clues about their nature. A paper outlining these results was uploaded to the preprint server arXiv on March […]

Theoretical models of supernova chemistry overhauled after X-ray data from Perseus Cluster reveal key discrepancies

The Perseus Cluster is a massive galaxy cluster located in the constellation Perseus. It is one of the largest structures in the observable universe, comprising more than a thousand galaxies—equivalent to roughly a thousand trillion times the mass of the sun. Hot gases within the cluster, known as the intracluster medium (ICM), emit powerful X-rays […]

Blue Origin reuses New Glenn booster for the first time in Florida launch

Blue Origin, the U.S. space company of Amazon founder Jeff Bezos, successfully reused and recovered a booster for its New Glenn rocket on Sunday, confirming its mastery of a technical feat that could boost its launch cadence and expand its rivalry with SpaceX.

DESI completes planned 3D map of the universe and continues exploring

The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone was reached when DESI’s 5,000 fiber-optic sensors captured their final scheduled observations, targeting a region of sky near the Little Dipper.

The moon might be more prone to fires

Engineers love a good practical challenge, especially when it comes to spaceflight. But there’s one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. For decades, we’ve relied on a NASA test known as NASA-STD-6001B to screen material flammability for flight. But space is much more […]

Volunteers discover rare space weather events using their ears

Our planet rests inside a magnetic cocoon filled with plasma—but it’s not always peaceful and quiet. Activity from the sun can send waves through this space, and some of those disturbances can even reach Earth, affecting our power grid.
