Humanity Star, we hardly knew ye. When Rocket Lab revealed in January that it sent a disco-ball satellite called “the Humanity Star” into orbit, as one of the payloads aboard its low-cost Electron rocket, the company said it could stay up shining in the night sky for nine months or so. But now Satview’s projection of the roughly 3-foot-wide, 20-pound satellite’s orbital decay indicates it will descend to a fiery doom on Thursday. Jonathan McDowell, a satellite watcher who works at the Harvard-Smithsonian Center for Astrophysics, told The Atlantic that Rocket Lab may not have taken full account of how… Read More
When your son comes home from school mumbling about lizard people and your daughter swears the moon landing was a con, you may be raising a conspiracy theorists. And, yes, that sounds crazy. But it’s shockingly common. Think, for just a moment, about the dumb things that kids are willing to believe. Anyone who buys...

Scientists Are Studying Rotting Animal Carcasses to Understand Why Complete Dinosaur Fossils Are So Rare
Paleontologists rarely find a complete skeleton from a prehistoric beast. New research from the University of Leicester and the University College Cork published in the journal Paleontology will help paleontologists understand the environmental factors that affected dinosaur carcasses before they left the fossils that scientists see and study today. Since you can’t watch a dead nonbird dinosaur decompose anymore, the researchers observed the next best thing—modern animal carcasses.
Stephen Hawking's ashes will be buried near the graves of fellow British scientists Isaac Newton and Charles Darwin at Westminster Abbey, it was announced Tuesday. The remains of the legendary physicist and icon, who died last week, will be laid in the church during a thanksgiving service later this year, the abbey said. Hawking died aged 76 on March 14 after a cosmic career in which his mental genius transcended his physical disability.
Late last year scientists spotted a totally unexpected visitor speeding its way through our Solar System. A long, cigar-shaped object had flown through our little celestial neighborhood at a breakneck pace and flung itself around the sun before heading back out into deep space. Eventually determined to be an asteroid, the object was named Oumuamua which means "scout," and some in the scientific community wondered if it might actually be an alien probe surveying our Solar System in search of life.
The alien theory was eventually brushed off after researchers listening to the object found it was dead silent, but many questions about its origins still remained. Now, after a few months of crunching the data, scientists believe they may have an idea of where the asteroid was born, and it's a whole lot different than what we're used to.
In a paper published in the journal Monthly Notices of the Royal Astronomical Society, researchers led by Dr Alan Jackson of the Centre for Planetary Sciences at the University of Toronto Scarborough suggest that Oumuamua is the product of a binary star system. Unlike our local star system, a binary star system features a pair of stars which orbit around a central point, constantly pulling on each other as they rotate.
The actual origin of Oumuamua is still totally unknown, but the team believes a binary star system is responsible for its creation due to simulations that demonstrate how effective that type of star system is at ejecting rocks at high speeds.
"It's remarkable that we've now seen for the first time a physical object from outside our Solar System," Jackson says. "It's really odd that the first object we would see from outside our system would be an asteroid, because a comet would be a lot easier to spot and the Solar System ejects many more comets than asteroids."
There was plenty of early speculation as to what type of body Oumuamua actually is, especially in the hours and days immediately following its detection. It was declared to be an asteroid, then a comet, and then an asteroid once again, but scientists seem to now have settled on it being a rocky body. Because of that, and because binary star systems would produce lots and lots of asteroids of varying shapes, chances are it was born in the grip of two stars, or at least that's the best guess thus far.
