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

TAMPA, Fla. — Airbus is expanding its partnership with in-orbit servicing venture Astroscale to explore ways to collaborate beyond potentially removing space junk and refueling satellites. The companies announced a memorandum of understanding (MoU) Aug. 12 — between Airbus Defense and Space and the Japanese venture’s British subsidiary — to focus on U.K.-based in-orbit servicing and

Cattle farming produces large amounts of greenhouse gases Alan Hopps/Getty Images With the world’s population growing, the only way to reduce the enormous greenhouse gas emissions from farming is to make food production ever more efficient. Unfortunately, efficiency gains have stalled since 2010, meaning farming emissions – and deforestation – could rise sharply as demand

WASHINGTON — Rocket Lab launched a Capella Space radar imaging satellite Aug. 11 on a mission that illustrated the flexibility offered by, but also the challenges facing, small launch vehicles. The Electron lifted off from Pad B at Rocket Lab’s Launch Complex 1 in New Zealand at 9:18 a.m. Eastern after a two-hour delay caused

A building’s design can influence its temperature Alistair Scott/Getty Images Walls with a protruding zigzag pattern could stay up to 3°C (5.4°F) cooler than regular walls, without using any energy. This approach could reduce the energy used by cooling systems and thus help limit global warming. “With this kind of design, we can have a
