Perseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters. NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam microphone. The discovery, published Nov. 26 in the journal Nature, has implications for Martian atmospheric chemistry, climate, and habitability, and could help inform the design of future robotic and human missions to Mars. A frequent occurrence on the Red Planet,…
This Black Friday was an incredible time to score a new Galaxy Watch at a lower price. The Galaxy Watch Ultra (2024) and the Galaxy Watch Ultra (2025) were both heavily discounted, as well as the Galaxy Watch 8 Classic and the Galaxy Watch 8. And while you might think that these discounts are now gone, since Black Friday and Cyber Monday are in the rearview mirror now, Lady Luck still allows you to save big on the regular Galaxy Watch 8 model.Now, I don’t know whether someone at Amazon has forgotten to tell it that Black Friday has ended…

Here’s how and when best to enjoy this spectacle of the year-end sky.What Is a Supermoon?The term supermoon refers to a full moon that occurs when our satellite is at perigee, the point at which its orbit brings it closest to our planet. (The…

We’ve been banging the drum for deals on reliable, large-capacity portable HDDs for a long time now. Honestly, going without one is really like doing a high-wire act without a net, because having only the one copy of your most sensitive and essential files that lives on your laptop or desktop leaves you one mishap away from losing them forever. Cyber Week’s one of the best opportunities to get protection for your irreplaceable data, and one of the best deals still on the board is this one at Amazon on the 5TB version of the WD My Passport external hard…
Select walls at NASA’s Johnson Space Center have been transformed into works of art. Each piece reflects creativity, collaboration, and the spirit of discovery. Painted by Texas students, the murals honor the legacy of the International Space Station and 25 years of continuous human presence in space. The International Space Station Program Mural Project began in 2022 as part of a broader effort to bring color and inspiration into the workplace while connecting classrooms to NASA’s mission. “The mural collection is a reminder that today’s dreams can be tomorrow’s realities,” said Space Operations Mission Directorate Deputy Associate Administrator Joel Montalbano.…
Zillow has dropped its climate risk score program after it started, . It has removed climate risk scores from over one million listings after real estate agents complained that the data was misleading and leading to lost sales.In their place, listings now feature a small link to data sourced from climate risk startup , which is the organization that provided the original assessment. The startup isn’t too happy about this move, with spokesperson Matthew Eby telling TechCrunch that “the risk doesn’t go away; it just moves from a pre-purchase decision into a post-purchase liability.” First Street’s climate scores still appear…
On Wednesday, three NASA astronomers released an analysis showing that several planned orbital telescopes would see their images criss-crossed by planned satellite constellations, such as a fully expanded Starlink and its competitors. While the impact of these constellations on ground-based has been widely considered, orbital hardware was thought to be relatively immune from their interference. But the planned expansion of constellations, coupled with some of the features of upcoming missions, will mean that at least one proposed observatory will see an average of nearly 100 satellite tracks in every exposure. Making matters worse, some of the planned measures meant to…
The Galaxy Z TriFold: humanity has outdone itself on this one. We are not yet fully sold on the idea of “traditional” foldables (phones that unfold just once, like the Galaxy Z Fold 7) and tri-foldables are already here.This phone is a tank, but in a good way. The Galaxy Z TriFold was unveiled yesterday, but I still can’t get out of my mind the fact that it comes with a built-in alarm system.See, the folding mechanism that vibrates and flashes a warning if you try to close it the wrong way. That’s pure dedication to preventing screen damage, especially…
If you work in photo or video editing, you already know that every extra bit of storage you can get your hands on feels like a lifesaver. Instead of deleting files you might eventually need, it’s almost always smarter to expand your storage capacity. That’s why compact external drives are so valuable. Stash away more data without taking up much space. And even though Black Friday has come and gone, that doesn’t mean you’ve missed your chance to snag a great deal on an external SSD. Right now, the SanDisk 2TB Creator Pro Portable SSD is discounted on Amazon well…
