Can some supernovas explode twice?

Nebulas are perhaps as famous for being identified

Have you ever watched a lightning storm in awe?

The cast of "Star Trek: Strange New Worlds" has to cover a wide range of dramatic genres, aided in part by the show's ample stockpile of wigs.

A new behind-the-scenes featurette from Hulu's upcoming 'Alien: Earth' show why the series will be pure nightmare fuel.

The European company Eos X Space has acquired Space Perspective, one of its key rivals in the nascent field of stratospheric balloon tourism.

Satellite data allows meteorologists to keep track of the location, structure and intensity of severe weather, helping to keep people safe. Now they're losing access to these satellites.

Mars will be less than four degrees from the crescent moon around sunset on July 28.

After an early morning launch from Florida, SpaceX sent another 24 Starlink satellites into orbit on a Falcon 9 launch from Vandenberg Space Force Base in California early on Sunday, July 27, 2025.

In the young V883 Orionis system, ALMA observations have revealed signatures of complex organic compounds such as ethylene glycol and glycolonitrile – potential precursors to amino acids, DNA, and RNA. These findings indicate that the building blocks of life may not be limited to local conditions but could form widely throughout the Universe under suitable circumstances.

What can brine (extra salty) water teach scientists about finding past, or even present, life on Mars? This is what a recent study published in Communications Earth & Environment hopes to address as a researcher from the University of Arkansas investigated the formation of brines using 50-year-old data. This study has the potential to help researchers better understand how past data can be used to gain greater insights on the formation and evolution of surface brines on the surface of Mars.

Los Angeles CA (SPX) Jul 22, 2025 Recent research led by Vincent Chevrier of the University of Arkansas offers new evidence that brines-salt-rich liquid water-could form on the Martian surface under specific seasonal conditions. Drawing on decades of research, Chevrier used atmospheric data from NASA's Viking 2 lander alongside advanced computer simulations to demonstrate that seasonal frost could briefly melt, creating small qu

Scientists studying the brightest gamma ray burst ever recorded have discovered evidence that these explosions produce complex, layered jets rather than simple uniform beams. This remarkable finding helps solve a long standing puzzle about how the universe's most powerful explosions work and opens new possibilities for observing similar events under challenging conditions.

A new five year study of 13 NASA astronauts shows that their arteries remain healthy and disease free long after returning from the International Space Station, offering reassuring news for future long duration space missions and suggesting the human cardiovascular system is more resilient to spaceflight than previously thought.

Next time you're drinking a frosty iced beverage, think about the structure of the frozen chunks chilling it down. Here on Earth, we generally see it in many forms: cubes form, sleet, snow, icicles, slabs covering lakes and rivers, and glaciers. Water ice takes all these fascinating forms, thanks to its hexagonal crystal lattice. That makes it less dense than nonfrozen water, which allows it to float in a drink, in a lake, and on the ocean.

NASA'S Hubble Space Telescope and NASA's Chandra X-ray Observatory have detected evidence of what could be an Intermediate Mass Black Hole eating a star. It's in a galaxy 450 million light-years away, and unusual x-ray emissions highlight its location.
