Lightning can produce special waves of energy RooM the Agency/Alamy An overlooked mechanism lets energy from lightning reach the highest layers of the atmosphere, where it could threaten the safety of satellites and astronauts. When lightning occurs, the energy it carries sometimes gives rise to special electromagnetic waves called whistlers, so named because they can

WASHINGTON — SpaceX launched the latest in its series of dedicated rideshare missions Aug. 16, putting more than 100 satellites for commercial and government customers into orbit. A Falcon 9 lifted off from Vandenberg Space Force Base in California at 2:56 p.m. Eastern on the Transporter-11 mission. The rocket’s booster, on its 12th flight, landed

An experiment with beams of photons has confirmed quantum weirdness exists luchschenF/Shutterstock The world is as weird as we feared. A new experiment confirms yet again the existence of correlations between distant entangled quantum particles – and this time we have measured the phenomenon so precisely, there is only a minuscule chance it is a

At the insistence of Rep. Mike Turner (R-Ohio), chair of the House Intelligence Committee, the  world now knows that Russia is developing some type of nuclear device that could be deployed on an orbiting satellite. No other intelligence has been publicly disclosed to indicate intent, but there’s a lot of hand wringing in the White

Exoplanets that get too close to their parent stars experience harsh conditions Nazarii_Neshcherenskyi/Shutterstock A distant Earth-sized planet is orbiting so close to its parent star that gravity is stretching it to an extreme degree, turning it egg-shaped. A handful of known exoplanets are extremely close to their parent stars, which exposes them to incredibly harsh

TAMPA, Fla. — Telesat expects to finalize government funds covering more than half the $3.5 billion budget for its planned low Earth orbit (LEO) broadband constellation “in the next couple of weeks,” CEO Dan Goldberg said Aug. 14. Canada’s flagship geostationary operator has had good engagement with the government of Canada and the government of Quebec,

Ocean temperatures have been rising steadily for decades, with our seas having absorbed much of the excess atmospheric heat generated by our relentless burning of fossil fuels. But in March 2023, almost overnight, they suddenly skyrocketed. Temperatures have since remained well above normal, reaching “hot tub” levels in some places, with disturbing consequences that suggest
