WASHINGTON (AP) — Scientists say they have at last solved the mystery of what killed more than 5 billion sea stars off the Pacific coast of North America in a decade-long epidemic. Sea stars – often known as starfish – typically have five arms and some species sport up to 24 arms. They range in color from solid orange to …

SpaceX launched another batch of its Starlink internet satellites to orbit from Florida early this morning (Aug. 4). A Falcon 9 rocket carrying 28 Starlink spacecraft lifted off from Cape Canaveral Space Force Station today at 3:57 a.m. EDT (0757 GMT). It was SpaceX’s 96th Falcon 9 launch of the year already. The rocket’s first stage came back to Earth …

A new paper has predicted that the universe’s expected lifespan is drastically shorter than once thought — and that the cosmos will start to die in just 10 billion years. This is only one possible theory, however, and nobody really knows when the universe will end. There are two leading theories for how the universe may die: the “Big Freeze” …

Recent simulations and research have unveiled a fascinating new insight into the history of the solar system’s terrestrial planets. For years, scientists speculated about how the rocky planets—Earth, Mars, Venus, and the mysterious long-lost world, Theia—formed and evolved in relation to one another. However, a recent study published in The Astrophysical Journal has provided new findings suggesting that these planets, …

The days are getting shorter and not just because summer is waning in the Northern Hemisphere. On Tuesday, Aug. 5, Earth’s solar day will be ever so slightly shorter than usual 24 hours, according to Timeanddate.com, making it not only one of the shortest days of 2025, but also since records began. At just 1.25 milliseconds under the 86,400-second mark, …

Between September 2003 and January 2004, the Hubble Space Telescope conducted its deepest observations of the cosmos ever. Known as the Hubble Ultra Deep Field, the images produced showed nearly 10,000 galaxies of various ages, sizes, and shapes, including some that existed when the Universe was just 800 million years old. Recently, astronomers were able to revisit this iconic snapshot …

“You didn’t mention camping on Mars.” My wife had a point: thin air, thinner soil, extreme UV, rocks straight from a Nasa red-planet image, jagged ranges – all ideal backdrops for a movie set. No wonder the place was considered for training by the Apollo program. Its sparse life forms include an intimidating shrub whose thorns mimic the stingers on …

Unlike typical AI research, where a model predicts outcomes or cleans up data, researchers at Emory University in Atlanta did something unusual. They trained a neural network to discover new physics. The team achieved this unique feat by feeding their AI system experimental data from a mysterious state of matter called dusty plasma, a hot, electrically charged gas filled with …
