Boeing to build braced-wing airliner, shooting for 30% efficiency gain
7 hours ago
When you burn as much fuel as an airline does, a single-digit fuel efficiency tweak adds up to massive savings. That'd be closer to half a billion a year for an operator like American Airlines, closing in on 1,000 planes in its fleet, from a 1% efficiency gain.

A little over six months ago, NASA's James Webb Space Telescope (JWST) delivered its first photographs, dazzling the world as it revealed the cosmos in glorious technicolor. The first picture transmitted in July showed a galaxy cluster located in the Southern hemisphere sky, 5.12 billion light years from Earth.

NASA's Fermi detects first gamma-ray eclipses from 'spider' star systems
5 days ago
Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar—the superdense, rapidly rotating remains of a star that exploded in a supernova—that slowly erodes its companion.
