Orbital dances unlock true masses of Orion’s young stars

A star’s mass determines its entire life story, from how it shines to how it dies. For young stars shrouded in dust, getting an accurate mass has long been difficult, but new radio measurements are beginning to change that. Astronomers are helping unravel the mass mystery of young stars in the Orion star-forming complex by […]

Q&A: Apollo astronaut Schmitt talks about getting back to the moon and life in the universe

It was 1972 and Apollo astronauts Harrison “Jack” Schmitt and Eugene Cernan had just stepped onto the moon’s surface to begin collecting rock and soil samples.

Milky Way’s ‘little cousins’ may hold clues about infant universe

Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new study published today in Monthly Notices of the Royal Astronomical Society uses an unprecedented set of simulations to show just how powerfully these faint systems can reflect the conditions of the early universe and tell us why […]

Moon dust could stop being a nuisance and start reshaping how humans may build beyond Earth

As space agencies and private companies look toward a sustained human presence on the moon, a fundamental challenge centers on how to build strong, durable infrastructure without hauling every material from Earth. New research from Rice University points to an unexpected solution—transforming one of the moon’s most stubborn obstacles, its abrasive dust, into a valuable […]

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 […]
