‘Standard candle’ (or type Ia) supernova explosions are some of the most energetic events in the Universe, happening when a dense white dwarf star subsumes another star. Now, scientists think they’re found the first evidence on Earth of such a supernova. The claim comes after a careful study of the extraterrestrial Hypatia stone that was … Read more
Many animal species that reproduce after they. But in octopus mothers, this decline is particularly alarming: In most species, as an octopus mother’s eggs get close to hatching, she stops eating. She then leaves her protective huddle over her brood and becomes bent on self-destruction† She might beat herself against a rock, tear at her … Read more

Jones and Muhua Sun/Rice University Scientists have demonstrated a new material that conducts heat 150% more efficiently than conventional materials used in advanced chip technologies. The device—an ultrathin silicon nanowire—could enable smaller, faster microelectronics with a … Read more
SpaceX plans to launch 53 more Starlink internet satellites and land the returning rocket on a ship at sea early Wednesday morning (May 18), and you can watch all the action live. A two stage Falcon 9 rocket topped with 53 starlink spacecraft is scheduled to lift off from NASA’s Kennedy Space Center in Florida … Read more
It’s apparently “just a gap” — but we’re still gonna mind it. By Open Apparently that photo of a “door” on the surface of Mars was cropped just so to make it seem like something much cooler than it really is. Over the weekend, a photo from NASA’s Curiosity Mars rover went viral because it … Read more
