When last we looked at the state of the US grid, the ongoing explosion in solar energy had turned it into a major contributor, but one that still lagged well behind fossil-fuel-powered generation. So it was a bit of a surprise when preliminary data suggested that May 2026 saw solar power pass coal-fired generation for…
On June 16, astronauts and cosmonauts gathered at Space Center Houston to share stories from their missions aboard the International Space Station and recognize the teamwork and people on the ground that made their missions possible. The Expedition 73 Welcome Home Ceremony brought together members of NASA’s SpaceX Crew-10, Soyuz MS-27, and NASA’s SpaceX Crew-11 missions….

Coryn Bailer-Jones’ The Physics of Interstellar Travel fills a need which has become apparent only in the last twenty years. Indeed, going back to the turn of the century, one would find the idea of traveling to another star discussed only in relatively isolated pockets, often presented at the tail end of conferences devoted to…
On the occasion of its 25th anniversary today, it’s worth noting a certain sense of irony that Steven Spielberg’s “A.I. Artificial Intelligence” seems oddly prescient into today’s AI-obsessed environment, especially when compared to the master director’s recently released “Disclosure Day,” which sadly feels three decades late to the whole governmental cover-up UFO/UAP party. “A.I.

Given no path, a group of explorers makes their own way through a cave. While one scouts ahead, others survey the area and map their progress. The demanding exercise is part of the outdoor and technical lectures five ‘cavenauts’ are receiving from ESA’s CAVES training before they head off to explore independently a cave system…
Astronomers have glimpsed the inner structure of a dying star in a rare kind of cosmic explosion called an “extremely stripped supernova.” In a paper published in Nature, Steve Schulze of Northwestern University in the United States and colleagues describe the supernova 2021yfj and a thick shell of gas surrounding it. Their findings support our…
With well over 6,000 exoplanets now confirmed and a continuing flow of data containing new detections, it has been clear for some time that our own Solar System’s model is hardly a template. I enjoy dipping into the bewildering variety of new systems and pondering the contingencies that have led to their architecture. Science fiction…
