Nimoy-Knight Foundation honors 'Girl Spock' and her mission to become the 1st openly autistic woman in space
The latest recipient of the Foundation's Live Long & Prosper Tribute Award is Jessica Schonhut-Stasik, an astrophysicist and neurodiversity advocate who is affectionately known as "Girl Spock."
UK government proposes 30% budget cut to astronomy and physics research: 'It's pretty disastrous'
The UK government is to slash by 30 percent its funding for astronomy, particle and nuclear physics in a move branded as disastrous for the field and likely to affect a generation of researchers.
4 upper-stage issues in 19 months: When will SpaceX's Falcon 9 rocket return to flight?
For the fourth time in the last 19 months, the upper stage of SpaceX's Falcon 9 rocket experienced a problem during a mission. How long will the vehicle be grounded this time?
Nearby star's massive eruption could help astronomers unlock secret of superflares
Astronomers witnessed a star emitting as much energy in mere moments as our sun puts out in a few months. The dramatic observation gives a direct look into the brutal physics of these stellar events.
ULA offloads first Vulcan rocket at Vandenberg at it preps its next Cape launch
A United Launch Alliance Vulcan booster is offloaded from the company’s R/S RocketShip barge at a dock at Vandenberg Space Force Base in California. This will be the first Vulcan rocket to launch from the West Coast. Image: United Launch Alliance
United Launch Alliance is staging rockets at launch complexes on both the West Coast and the East Coast for the first time since November 2022.
SpaceX Dragon arrives for Crew-12 launch | Space photo of the day for Feb. 6, 2026
Crew-12's timeline has been unusually dynamic.
The Dirty Afterlife of a Dead Satellite
Sometimes humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself it a perfect example of that - no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase the overall global temperature and risk millions of people's lives and livelihoods, let alone the impact it would have on the species we share the world with. According to a new release from the Salata Institute at Harvard, we seem to be going down the same blind path with a different engineering challenge in this century - satellite megaconstellations.
Does dark matter actually exist? New theory says it could be gravity behaving strangely
"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate."
This Week's Sky at a Glance, February 6 – 15
The Winter Hexagon encompasses the brightest winter stars. Near Orion, the Big Dog prances and the Hare crouches. And the moonless dark this week opens telescopic deep-sky depths.

Earth from Space: Olympic view
Image: With the 2026 Winter Olympics officially opening today, the Copernicus Sentinel-2 mission brings us a striking view of northern Italy, highlighting several key Olympic venues.
The curious case of why methane spiked around Covid
With fewer cars on the road, planes in the air and factories running, the skies seemed cleaner during the Covid-19 pandemic. However, while there was a decline in pollutants such as nitrogen dioxide, scientists were surprised to see that methane surged in the early 2020s and then dropped – and now they know why.
The "Little Red Dots" Observed by Webb Were Direct-Collapse Black Holes
The James Webb Space Telescope (JWST ) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the Universe has evolved from the earliest cosmological epoch to the present. When Webb first trained its advanced optics and instruments on the early Universe, it discovered a new class of astrophysical objects: bright red sources that were dubbed "Little Red Dots" (LRDs). Initially, astronomers hypothesized that they could be massive star-forming regions, but this was inconsistent with established cosmological models.
The 10 bleakest space movies of all time
From spaghettified convicts to doomed interplanetary liners, these space movies really pile on the misery.
Is There A Link Between Primordial Black Holes, Neutrinos, and Dark Matter?
Humanity has worked itself into a position where we can detect a single high-energy particle from space and wonder where in Nature it came from. Billions of people likely don't care at all about such matters, but for those that are naturally curious and are fortunate enough to have the time to indulge their curiosity, an extremely energetic neutrino detected in 2023 was a remarkable event, and may even turn out to be an historic one.
