NASA launched two rockets from Alaska this week to learn more about the electrical "circuitry" within auroras.
Picture this…. you’ve spent five years building an exquisitely sensitive scientific instrument. You’ve tested it, shipped it halfway around the world, reassembled it in Antarctica, and now you’re watching it disappear into the blue sky aboard a giant balloon. For the next three weeks, all you can do is monitor it from the ground and hope everything works.
Following the announcement that Amazon has given a new 'Stargate' the go-ahead, franchise figureheads Martin Gero and Joseph Mallozzi shared some of the details.
Imagine a star that’s been shining steadily for decades, and then suddenly it dims to just 3% of its normal brightness. Not for a few days or weeks, but for more than nine months. That’s exactly what happened to ASASSN-24fw, a star sitting 3,200 light years away in the constellation Monoceros.
When you look at a volcano, you’re seeing the tip of a vastly more complicated system. The mountain itself is just the exit point for processes that have been happening deep underground, perhaps for millions of years. Magma doesn’t simply appear at the surface ready to erupt it rises, stalls, cools, changes, and evolves in underground chambers before finally breaking through.
After a recent explosive outburst, Comet 29P/Schwassmann-Wachmann is bright enough to see in a medium-sized telescope.
The Crew 12 fliers cavort aboard the International Space Station shortly after floating inside Saturday. They joined station commander Sergey Kud-Sverchkov, back left in black shirt, NASA astronaut Chis Williams and cosmonaut Sergey Mikaev, both wearing black shirts.

A SpaceX Crew Dragon capsule glided in for a Valentine’s Day docking at the International Space Station Saturday boosting the lab’s crew back to a full complement of seven one month after four other fliers came home early because of a medical issue.
Scientists have been making some incredible discoveries in space that are shedding new light on the origins of life. In addition to finding amino acids in asteroids, scientists have also found fatty acids found on Mars, sulfur-bearing molecules in interstellar space, and that peptides form spontaneously in space. Most recently, research based on data from the James Webb Space Telescope (JWST) has found an abundance of small organic molecules in a nearby galaxy.
China has achieved several impressive milestones in its space program in recent years. As part of their plan to build an outpost on the Moon that will compete with NASA's Artemis Program - the International Lunar Research Station (ILRS) - they are busy developing a super-heavy launch system and a crew-capable spacecraft that will take taikonauts to the Moon by the end of the decade. That is the plan, at any rate, and recent tests indicate that they are on track to achieve that goal. On Wednesday, Feb. 11th, the China Manned Spaceflight Agency (CMSA) completed a major test of its Long March-10 rocket and the Mengzhou spacecraft.
The SpaceX Dragon Freedom capsule carrying ESA astronaut Sophie Adenot, NASA astronauts Jessica Meir and Jack Hathaway, and Roscosmos cosmonaut Andrei Fedyaev, docked with the International Space Station on 14 February, at 20:15 GMT/21:15 CET, marking the official start of ESA’s εpsilon mission.

Update Feb. 14, 10:45 p.m. EST (0345 UTC): SpaceX deployed the 24 Starlink satellites.
Whether you're single, in a relationship, or even a situationship, fall in love with these sci-fi couples this Valentine's Day.
From 'Roswell' to 'Outlander,' these romantic sci-fi TV series are guaranteed to warm cold hearts this winter.
On Episode 197 of This Week In Space, Rod Pyle and Tariq Malik talk with Aarti Holla-Maini and Rick Jenet about the importance of the United Nations Office of Outer Space Affairs.
The Rosette Nebula is located 5,000 light-years from Earth in the constellation Monoceros.
Astronomers have spotted a heart in the cosmos — not Cupid's doing, but a dying star shedding its layers — just in time for Valentine's Day.

Flying in the face of superstition, NASA and SpaceX conducted a smooth countdown and launch of three astronauts and a cosmonaut to begin the latest, long-duration mission to the International Space Station on Friday, Feb. 13.
SpaceX's Crew-12 astronaut mission will dock with the short-staffed International Space Station this afternoon (Feb. 14), and you can watch the off-Earth action live.
Ten years ago, humanity detected its first gravitational wave. On 14 January 2025, we detected the clearest one yet and it’s teaching us new things about the fundamental laws governing our universe.
The universe was supposed to take its time building the largest structures in existence. Galaxy clusters, containing hundreds or thousands of individual galaxies bound together by gravity and immersed in enormous pools of superheated gas, should require billions of years to assemble. Standard models predict these monsters couldn’t possibly form in the universe’s early childhood.
