Reading the moon’s buried past

The lunar south pole looks chaotic from orbit. Craters heaped upon craters, ancient basins, scarps and slopes tumbling in every direction, it is without doubt, one of the most geologically complicated terrains in the inner solar system. That aside, it’s exactly where we intend to send people, since understanding what lies beneath that battered surface […]

The universe’s most powerful telescope

SN 2025mkn is a Type II supernova and it wasn’t supposed to be visible at all. The violent death of a massive star that had exhausted its nuclear fuel and collapsed under its own gravity sits at a redshift of 1.371. That places it roughly 9 billion light years away. At that distance, an ordinary […]

Astronomers reveal always-changing multi-planet system

Astronomers at The University of New Mexico have published new research confirming three bodies orbiting the dynamic exoplanet system TOI-201. They include a super-Earth (TOI-201 d), a warm Jupiter (TOI-201 b), and a brown dwarf (TOI-201 c).

A monster black hole appeared first, then its galaxy began to grow around it

Using observations gathered by the James Webb Space Telescope (JWST), an international team of astronomers have revealed that one supermassive black hole in the early universe must have formed before a galaxy developed around it. Publishing their results in Monthly Notices of the Royal Astronomical Society, a team led by Roberto Maiolino at the University […]

JWST spots methane on a giant exoplanet, but its star may be distorting the signal

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new observations, published April 8 on the arXiv pre-print server, yield important information on the atmosphere of this planet.

Subaru telescope captures comet 3I/ATLAS composition change

The Subaru Telescope observed the interstellar comet 3I/ATLAS on January 7, 2026, after it made its closest approach to the sun. By observing colors in the coma around the comet, astronomers could estimate the ratio of carbon dioxide to water. This ratio is much lower than that inferred from earlier observations by space telescopes. These […]

Research helps power safe return of astronauts in historic Orion splashdown

When NASA’s Orion capsule splashed down in the Pacific Ocean April 10, completing a successful Artemis II mission milestone, a critical piece of the spacecraft’s safe return traced back to research at Rice University.

Young stars dim quickly in their X-ray output, potentially benefiting orbiting planets

Scientists have found that young stellar cousins of our sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results is published in The Astrophysical Journal. Unlike in the new movie “Project Hail Mary,” this quieting […]

Catching distant gamma-ray explosions with precisely aligned X-ray optics

Gamma-ray bursts (GRBs) rank among the most powerful explosions in the universe, releasing immense energy in intense flashes of gamma rays. The most distant GRBs originate from the era when the first stars and galaxies formed. Detecting them allows astronomers to probe the early universe and understand how the first heavy elements formed and how […]

Not so dark with Alena Tensor: Math framework could explain dark matter without invisible particles

Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, spontaneously gives rise to the phenomena known from research on dark matter and dark energy.

Virtual sunspots help AI find rare magnetic matches in vast solar archives

Research led by Southwest Research Institute (SwRI) has integrated three types of machine learning models to generate solar magnetic patches with physical properties and used those as a query to find matching patches in real observations. This elevates generative artificial intelligence (AI) from a means to produce artificial data to a novel tool for scientific […]

Webb redefines the dividing line between planets and stars

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.

Shredded stars reveal how black holes ignite trillion-sun flares

Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions of times the mass of the sun and sit at the centers of most large galaxies. At the heart of the Milky Way lies Sagittarius A*, our galaxy’s supermassive black hole, with a mass of about […]

Torsion balances set strongest direct limits yet on ultralight dark matter

Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most past experiments have focused on heavier dark matter candidates, while much lighter dark matter, with masses closer to the mass of a neutrino, has been difficult to detect directly because its scattering […]

The quietest place we’ve ever listened from

We have been searching for signals from other civilizations for over sixty years. Radio telescopes on Earth have swept the sky, listened patiently, and found nothing but silence. It is a search that demands extraordinary sensitivity and that is the problem. Earth and our very existence itself are getting in the way.
