The Zhamanshin impact event was likely much more destructive than thought

Earth and the course of life on Earth have been shaped by impacts. Scientists have uncovered links between massive impacts and changes in climate that altered the planet forever. But the further scientists look into the past to try to understand these changes, the more difficult it is to link them together.

‘Bathtub ring’ hints at ancient Martian ocean

Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet’s surface. The research was conducted by former Caltech postdoctoral scholar Abdallah Zaki and Caltech professor of geology Michael Lamb. The study is described in a paper appearing in the journal Nature.

Dark volcanic ash has visibly reshaped Martian surface since 1976

Noticeable change on Mars often takes millions of years—but the European Space Agency’s Mars Express has captured a blanket of dark ash creeping across the planet in just decades.

A 3D map of 47 million galaxies is redefining our view of the universe

For the last five years, the Dark Energy Spectroscopic Instrument (DESI) has been systematically scanning the night sky. Today marks the completion of its first map, which is the largest high-resolution 3D map of the universe ever made.

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).

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 stellar explosion simply doesn’t produce enough light to study in any useful detail. Yet astronomers can see this one with extraordinary clarity and we have gravity to thank.

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 isn’t just scientific curiosity. It’s the essential groundwork for everything that follows.

Any color you like: Scientists create ‘any wavelength’ lasers in tiny circuits for light

Computer chips that cram billions of electronic devices into a few square inches have powered the digital economy and transformed the world. Scientists may be on the cusp of launching a similar technological revolution—this time using light.

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 of Cambridge hope their results could lead to a better understanding of the origins of these immense objects.

Multitasking quantum sensors can measure several properties at once

A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using classical sensors alone. Such quantum sensors are currently being used to study the inner workings of cells and the outer depths of our universe.

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 findings suggest that the chemistry of the coma is evolving over time and offers clues to the structure of comet 3I/ATLAS. The work appears in The Astronomical Journal.
