The most pristine star yet found in the known universe

The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie's Cong Liu and Ronald Cohen. Their work, published in Nature Communications, predicts that a quasi-one-dimensional superionic state of carbon hydride exists under the extreme pressures and temperatures found deep inside these outer solar system bodies.

An international team of researchers, led by paleontologists of the University of Liège, has investigated the biting capabilities of extinct predatory marine reptiles, revealing how these formidable predators could coexist within the same ecosystem. This work sheds new light on the hunting strategies of long-extinct predators that dominated the seas during the Age of Dinosaurs. The research is published in the journal Palaeontology.

Today marks the 100th anniversary of the birth of Virgil I. “Gus” Grissom, born April 3, 1926, in Mitchell, Indiana. As one of NASA’s first seven astronauts, he became America’s second astronaut to fly in space when he launched aboard the Liberty Bell 7 spacecraft on July 21, 1961, just weeks after Alan Shepard’s historic […]

We're getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we're looking at an Earth analog somewhere else in the galaxy, we have to directly image it too. That's a job for the Habitable Worlds Observatory (HWO), a planned space-based telescope whose primary job is to do precisely that. But even capturing a picture and a planet and getting spectral readings of its atmospheric chemistry still isn't enough, according to a new p
