“They’re putting operational systems up within orbit reach of our high-value satellites.” After several tests of unusual “nesting doll” satellites in low-Earth orbit, Russia is now fielding operational anti-satellite weapons with valuable US government satellites in their crosshairs, the four-star general leading US Space Command said this week. Gen.…
Spy satellite hardware has been repurposed to scan the Universe in the infrared. GREENBELT, Md.—On Tuesday, NASA invited the press to look at the fully assembled Nancy Grace Roman Space Telescope, which is now ready to join the ranks of the great observatories in orbit, ahead of its September…
Results dash hopes for a fifth force but provide very precise proof of Standard Model and QFT. Physicists have spent the last 20 years pondering an apparent discrepancy between experimental results and theoretical predictions for the magnetic properties of the muon, the electron’s heavier cousin—a mismatch that hinted at…
Added layers of review singling out renewable energy have little legal basis. On Tuesday, the US District Court for the District of Massachusetts issued a preliminary injunction blocking the US government from applying a range of restrictions on renewable power development, at least for the parties in the suit. The…
The International Energy Agency says we’ve entered the Age of Electricity. On Monday, the International Energy Agency released its analysis of the energy trends of 2025, covering the entire globe. It confirms and extends the primary conclusion of a more limited analysis by the International Renewable Energy Agency: 2025…
Problems with the ground system would have “put current GPS military and civilian capabilities at risk.” The Pentagon has canceled a ground control system for the US military’s GPS satellite navigation network after the program’s enduring problems “proved insurmountable,” the US Space Force announced in a press release Monday. The…
Kea parrot missing his upper beak “has rewritten what disability means for behaviorally complex species.” Bruce the kea—a species of alpine parrot native to New Zealand—lost his upper beak in an accident as a young bird. But that hasn’t stopped him from becoming the dominant male in his kea…
Blue Origin’s reused first stage hit its targets, but New Glenn’s upper stage did not. The third flight of Blue Origin’s heavy-lift New Glenn launcher began Sunday with the company’s first successful reflight of an orbital-class booster, but ended with a setback for Jeff Bezos’ flagship rocket, a key…
The laser was used to study the physics of stellar interiors and fusion energy, among other things. If you walk across the open yard in front of the Physics, Math, and Astronomy building at the University of Texas at Austin, you’ll see a 17-story tower and a huge L-shaped…
The sharks might also be the most physiologically vulnerable to warming waters. The evolutionary edge that fueled great white shark dominance for millions of years could soon become its greatest downfall. The ocean’s most iconic predators maintain warmer body temperatures than the surrounding seawater and are paying an increasingly…
