TAMPA, Fla. — Hawaiian Airlines announced Sept. 24 the start of free Starlink Wi-Fi on most of its transpacific fleet flying to and from Hawaii. The company said it has finished installing antennas for SpaceX’s low Earth orbit (LEO) network across the 42 Airbus aircraft in its fleet — 24 A330s and 18 A321Neos —

Axolotls appear to age very little over their lifetimes SeaTops / Alamy Ever wished you could hit the pause button on ageing? At least one creature may do just that. Axolotls seem to halt one of the hallmarks of the process part way through their lives, a finding that could shed new light on ageing

WASHINGTON — The U.S. Space Force selected four companies to develop concepts for smaller, more cost-effective GPS satellites based on commercial designs, aiming to augment the existing Global Positioning System network, the Department of the Air Force announced Sept. 23. Astranis, Axient, L3Harris Technologies and Sierra Space have been chosen to submit proposals for the

A day octopus hunting with a blue goatfish Eduardo Sampaio and Simon Gingins Octopuses are even more sophisticated than we thought. Despite generally being solitary animals, they can work with fish to find prey and recognise which team members aren’t helping. That is the conclusion of a study of “hunting packs” that consist of a

Gravitational wave detectors use laser beams in tubes that span kilometres The Virgo Collaboration Gravitational waves that span thousands to billions of miles can be obscured in our detectors by the smallest of quantum fluctuations that permeate space-time. But now, researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have found a way to beat this
