Jonathan Allen, a biology professor at The College of William & Mary in Virginia, has a very strange pet: a very very long ribbon worm (phylum nemertea) named Baseodiscus the Eldest, or just B for short. Ribbon worms, also called nemerteans, are one of the longest animals on Earth, but Allen isn’t horrified...

Neutrinos are among the most puzzling particles known to science and are often called ‘ghost particles’ because they so rarely interact with matter. Trillions pass through each person every second without leaving any mark. These particles are created during nuclear reactions, including those inside the Sun’s core. Their extremely weak interactions make them exceptionally challenging to study. Only a few materials have ever been shown to respond to solar neutrinos. Scientists have now added another to that short list...

Of the seven Earth-sized planets circling the red dwarf star TRAPPIST-1, one world has become a special focus for astronomers. This planet, TRAPPIST-1e, orbits within the star’s “Goldilocks zone” — a region where temperatures could allow liquid water to exist on the surface — but only if the planet has an atmosphere to help regulate those conditions. Where liquid water can persist, the possibility of life follows naturally. Two recent scientific papers report the first detailed observations of the...

Nearly 70 million years ago, mosasaurs were the stuff of nightmares. Multiple species of the apex marine reptiles lived during the Late Cretaceous, often growing anywhere from 30 to 40 feet-long.

ORLANDO, Fla. — The U.S. Space Force is rolling out a new naming scheme for its satellites, cyber tools and other space-warfare systems, a move aimed at giving its arsenal the kind of recognizable identities long used across the military. In a keynote address at the Spacepower conference Dec. 11, Chief of Space Operations Gen. Chance Saltzman said the service will begin assigning meaningful nicknames to operational systems, drawing on themes meant to reflect each mission area’s character and...

ORLANDO, Fla. — U.S. Secretary of the Air Force Troy Meink cautioned that the United States should not assume China’s accelerating progress in space and missile technology is simply the result of copying American systems, arguing Beijing is demonstrating significant independent innovation. Speaking Dec. 11 at the Spacepower conference, Meink said he recently toured Space Force launch facilities at Cape Canaveral and was struck by how closely China’s newest launch complexes resemble U.S. ranges. “You actually look at some...

Paris, France – Released today, Novaspace’s latest FSS Operators: Benchmarks & Performance Review unveils a year of transformation for satellite operators. 2025 is redefining the rules of the game for Fixed Satellite Service (FSS) operators. Faced with rising cost pressures and NGSO-driven disruption, operators are doubling down on diversification, multi-orbit strategies, and consolidation to stay competitive. Multi-orbit deployment surged in 2025, with 24 operators now embracing multi-orbit strategies. Meanwhile, vertically integrated giants such as SpaceX, Viasat-Inmarsat,...
