A new private spacecraft aims to help the U.S. military get key supplies where they’re needed, and fast. On Wednesday (Oct. 1), the California-based company Inversion unveiled Arc, a vehicle designed to serve as an orbital storehouse and superfast delivery system for mission-critical gear, getting it anywhere on Earth in less than an hour. “With massive cross-range to cover great …

The Book of Exodus tells of a miraculous parting of the Red Sea that allowed Moses and the Israelites to escape Egypt. Now, science has an older and more extreme tale to tell: About 6.2 million years ago, the Red Sea dried up completely. Some millennia later, the dried seabed filled back up in a cataclysmic flood that may have …

The near-Earth asteroid 2025 TF (red crosshairs) came about as close to Earth as the International Space Station on Wednesday (Oct. 1), evading detection until hours later. (Image credit: ESA / Las Cumbres Observatory) A small asteroid zoomed past Earth closer than most satellites last week — and astronomers didn’t notice it until hours later. The surprise asteroid encounter occurred …

Asteroid 2025 TF flew over Antarctica at 00:47:26 UTC ± 18 s on 1 October, coming as close as 428 ± 7 km to Earth’s surface. This is a similar altitude to the orbit of the International Space Station (approx. 370—460 km). The asteroid is roughly 1 to 3 metres across and was first spotted by the Catalina Sky Survey …

For nearly twenty years, satellites have quietly gauged the flow of sunlight and heat through the Earth’s atmosphere. Today, scientists say those measurements indicate a disturbing trend — the Northern Hemisphere is steadily getting darker compared to the Southern Hemisphere. The discrepancy could redefine wind patterns, ocean currents, and even global temperatures. Tracking the Planet’s Energy Flow The study relies …

In late August 2025, at Edwards Air Force Base in California, pilot Kirt Stallings sat suited up and ready to go inside a transport vehicle, mere moments from boarding NASA’s high-altitude ER-2 aircraft. Through the window, ground crews readied the long-winged plane for a geological mapping mission as part of the Geological Earth Mapping Experiment (GEMx). What is it? GEMx …

Earth’s surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks of Earth’s crust. This movement may be why life exists here. Earth is the only known planet with plate tectonics and the only known planet with life. Most scientists think …

But whereas this radial velocity technique is, for now, limited to ground-based observatories and can only observe one star at the time, the transit technique can be employed in space telescopes such as the French Corot (2006-14) and Nasa’s Kepler (2009-18) and Tess (2018-present) missions. Between them, space telescopes have detected thousands of exoplanets in all their diversity, taking advantage …
