Astronomers from the California Institute of Technology (Caltech) and elsewhere report the discovery of a binary system consisting of two brown dwarfs undergoing stable mass transfer. The detection of the system, designated ZTF J1239+8347, was made with the Zwicky Transient Facility (ZTF) and is detailed in a paper published March 18 in The Astrophysical Journal […]
Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation TOI-4616 b, is slightly larger than Earth. The finding was reported in a research paper published March 11 on the arXiv pre-print server.

There is a place in northern Chile, 3,500 meters above sea level in the Andean Altiplano, where almost nothing survives. The Salar de Pajonales is a salt flat of savage extremes temperatures swinging from −23°C to 26°C, solar radiation among the highest measured anywhere on Earth, annual rainfall that barely registers, and winds that rip […]
Neptune is the solar system’s most distant planet, a cold, blue ice giant sitting nearly 30 times further from the sun than Earth. At that remote distance, temperatures plunge to nearly minus 200 degrees Celsius and a single year lasts 165 Earth years. Yet despite its isolation, Neptune is a world whipped by the fastest […]
More than 10,000 Starlink satellites currently orbit Earth. We see them crawling across dark skies, no matter how remote our location, and streaking through images from research telescopes.

One of the things astronomers find when they look around at galaxies is a correlation between a galaxy’s mass and the mass of its supermassive black hole. Contrary to popular belief, these SMBH don’t anchor their galaxies; they make up only a small portion of a galaxy’s mass. In local galaxies, the ratio of SMBH […]
General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from rotational frame dragging to the radiation of gravitational waves. But there is reason to believe that it is not the final say on the nature […]
Researchers at NYU Abu Dhabi have discovered new large-scale waves moving deep inside the sun, driven by magnetic fields far below the surface. These waves provide a window into parts of the sun that are otherwise inaccessible, giving scientists a new tool to study how its magnetic field is formed and evolves over time.

When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in “The Empire Strikes Back,” and we often hear how they are remnants from the birth of the solar system. While the asteroids that comprise the Main Asteroid Belt of our solar system are not only […]
The astronauts set to become the first lunar visitors in more than half a century arrived at their launch site Friday, joining the towering rocket that stands poised to blast off next week and send them around the moon.

Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science—why does Saturn appear to spin at a different speed depending on how you measure it? The findings, published in the Journal of Geophysical Research: Space Physics, reveal for the first time the […]
A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA/ESA Hubble Space Telescope Picture of the Month image. IC 486 lies right on the edge of the constellation Gemini (the Twins), about 380 million light-years from Earth. Classified as […]
Scientists are working to understand how magnetic currents from the sun spread beneath Earth’s crust when the northern lights dance across the sky. Their goal is to tame its “dark twin” and prevent damage to our power grid.

NASA is once again shooting for the moon, for the first time since the 1970s. As soon as April 2026, NASA will launch its Artemis II mission, using the Space Launch System heavy lift rocket to send a crewed spacecraft, called Orion, into orbit. From there, the crew will circle around the moon over 10 […]
