Scientists have discovered the oldest solid material ever found on Earth from a meteorite that fell in Australia about 50 years ago.
The material that the researchers examined are called presolar grains – or stardust – particles from a star that can eventually form new stars, along with planets, moons and meteorites.
A striking MRI scan of a pug’s head which has charmed sections of the internet is actually a reminder of the problems the dogs suffer from because of human breeding, a leading vet has said.
A tweet showing the black and white image of the pug went viral this week, garnering almost 130,000 likes.
The picture is dominated by the pug’s huge bulging eyes, while the animal almost seems to have a quizzical expression.
Many of those commenting on and sharing the image described it as adorable and cute, but Rory Cowlam, a vet based in London, said it was actually concerning.
As an Atlas 5 rocket arced upward into the pre-dawn sky from Cape Canaveral in Florida on Friday morning, NASA’s plans to finally break free of its reliance on Russian rockets for taking astronauts to orbit seemed to be on track.
On top of the rocket was Starliner, a capsule built by Boeing, part of a NASA strategy to delegate to private companies to handle the astronaut transportation.
Half an hour later, something went wrong, signaling that NASA would again face a setback to its goal of renewing human spaceflight to orbit from the United States.
A black hole with a mass 70 times greater than the Sun was discovered, leaving scientists stunned.
"Black holes of such mass should not even exist in our Galaxy, according to most of the current models of stellar evolution," Professor Jifeng Liu, who led the team at the Chinese Academy of Sciences that made the discovery, said in a statement.
Scientists previously believed that the mass of an individual stellar black hole could not be more than 20 times that of the Sun. These stellar black holes are different than so-called supermassive black holes, which are found at the center of galaxies and can be billions of times the mass of our Sun.
While people around the world were celebrating the arrival of 2019, people at the Johns Hopkins Applied Physics Laboratory in Maryland were hard at work. Billions of miles away, the New Horizons probe was flying past Ultima Thule, a small object in the Kuiper Belt. By Tuesday morning, the hardware had sent back a status report that indicated the flyby went as planned, and New Horizons now has lots of data from Ultima Thule that it will slowly send back to Earth over the coming months.
While we don't yet have any of the data that will tell us details about this relic of the Solar System's formation, images taken during the approach solved one of the mysteries that had arisen as New Horizons closed in. But one of the key questions—is Ultima Thule one object or two?—remains unanswered.
An American astronaut and Russian cosmonaut were forced to eject from an aborted launch to the International Space Station early Thursday and make an emergency landing.
NASA astronaut Nick Hague and Roscosmos cosmonaut Alexey Ovchinin were aboard the spacecraft when it launched at 4:40 a.m. EDT on a mission to the station. The duo blasted off from Kazakhstan's Baikonur Cosmodrome aboard the Russian Soyuz MS-10 spacecraft.
Moments after launch, the two were forced to eject from the spacecraft after they encountered trouble with a booster on the rocket.
A mummified wolf pup and caribou believed to have walked Earth over 50,000 years ago were discovered with tissue and fur intact — a remarkable find, Canadian authorities say.
The caribou was found at the site of a 80,000-year-old volcanic ash bed and officials believe it's among the oldest mummified mammal tissue in the world, according to a release.
The head, two front limbs and torso of the caribou were intact. The wolf pup was found with a complete body.
