Could NASA use expandable habitats for its Artemis moon bases? These two companies are betting millions
Voyager Technologies is backing lunar habitat developer Max Space with a new multi-million-dollar investment aimed at accelerating development of expandable modules for future missions to the moon.
Super-Bright Supernovae Are Magnetar Birth Cries
The disk of gas that spirals onto a newborn magnetar wobbles, creating "bumps" in the brightness of the supernova that accompanied this object's birth.
'In the old days, we were staring at a f ***ing green screen with tape marks on it': We talk to 'Star Trek' legend Jonathan Frakes about directing 'Starfleet Academy' season 1's penultimate episode
'The scope of 'Starfleet Academy' in terms of design, art direction, visual effects, practical effects, and graphics is massive.'
Looking for Supermassive Black Hole Binaries with a Flash of Starlight
Most galaxies have a supermassive black hole at their center, but some galaxies have two. These supermassive binaries form when two galaxies collide and merge. We can detect some of these binaries, such as by observing the periodic changes of a quasar or by observing the binary directly, such as in the case of NGC 7727. But most supermassive binaries remain hidden. They are too far away to be observed directly or too inactive to be observed by jets. And while gravitational wave observatories can detect the mergers of stellar-mass black holes, we can't yet detect the mergers of supermassive black holes. But a new study shows how we might detect some of them.

The 'invisible giant' at the heart of our galaxy | Space photo of the day for March 11, 2026
A new image captured by the Very Large Telescope reveals stars and gas orbiting the "invisible giant" at the heart of our galaxy.
'War Machine' succeeds where 'Transformers' fails, by making its giant robot feel real
Autobots, roll out – out of the way, that is, because War Machine is proving how to do human vs intergalactic machine conflict better.
NASA's DART planetary defense mission reveals asteroids hurling 'cosmic snowballs' at each other
New images from NASA's DART asteroid-smashing mission show space rocks exchanging material in a slow process that reshapes their surfaces over millions of years.
Researchers Create a Nanoengineered Light Sail That Won't Melt
Traditional chemical rockets, though they are the most commonly used propulsion method for space exploration today, are beholden to the tyranny of the rocket equation. Every ounce of thrust they use must also start out as fuel, which means the rocket itself will have to weigh more, and weight is one of the limiting factors in how fast a propulsion system can go. So, scientists have been searching for, and actively testing, alternatives for decades. One of the most promising is the solar sail - a huge reflective sheet that uses sunlight, or in some cases a “pushing laser” to maneuver about the solar system without any onboard propellant necessary. A recent paper published in the Journal of Nanophotonics by Dimitar Dimitrov and Elijah Taylor Harris of Tuskegee University describes a new type of light sail that solves some of the major problems of existing designs.
NASA Artemis 2 gifts we love: Top picks for aspiring astronauts
Ready to launch your support? Check out this stellar collection of space-flight merch I've personally picked to back the amazing team of the NASA Artemis 2 mission.
China's Space Programme Prepares for Its Busiest Year Yet
The Chinese didn't invent the rocket but they came remarkably close. More than a thousand years ago, during the Song Dynasty, Chinese engineers were packing black powder into bamboo tubes and launching fire arrows that hissed across battlefields on jets of smoke and flame. Those crude devices were the distant ancestors of every launch vehicle that has ever punched through Earth's atmosphere and there's a pleasing symmetry in the fact that, today, China operates one of the most capable and ambitious space programmes on the planet. From its first satellite in 1970 to a fully operational crewed space station orbiting overhead right now, the journey has been extraordinary. And in 2026, it's about to get even more interesting.
Interstellar comet 3I/ATLAS is 'bursting with methanol,' new study finds
The interstellar comet 3I/ATLAS is unusually rich in alcohol — a chemical clue that could reveal how planets and icy bodies form around other stars.

NASA is working to reduce the risks of upcoming Artemis moon missions, but there are “gaps” in the agency’s approach, including in planned tests of some critical lander systems, the agency’s Office of Inspector General said in a report released Tuesday.
Jupiter's moons leave cold 'footprints' in the planet's auroras, James Webb Space Telescope finds
Never-before-seen temperature and ion density measurements reveal that the effect of Jupiter's moons on its aurora are more complicated than scientists thought.
Asteroid Didymos's Orbit Altered by Impact on its Moon
Dozens on amateur astronomers helped measure the minuscule difference in Didymos’s trajectory around the Sun, after NASA’s DART mission impacted its moon.
