By creating conditions akin to the center of the Earth inside a laboratory chamber, researchers have improved the estimate of the age of our planet's solid inner core, putting it at 1 billion to 1.3 billion years old. The results place the core at the younger end of an age...
From schools of fish, to herds of antelope and even human societies, one of the group's many advantages is its inherent safety. Surrounded by their peers, individuals can lower their vigilance and calmly engage in other activities, such as foraging, or watching YouTube videos. But the Safety in Numbers rule...
While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2400 light-years away. The name of the supernova remnant comes from its position in the northern...
A Russian cosmonaut has spotted a group of five UFOs moving over Earth while he was filming a time-lapse video on ISS. As Russian cosmonaut Ivan Vagner, who is currently onboard the International Space Station (ISS), was filming an aurora over Antarctica, several strange lights were spotted. The 60-second clip,...
Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth's rock record could confirm this scenario. Imagine reading by the light of an exploded star, brighter than a full moon -- it might be...
Greenland’s ice sheet lost a record amount of mass last year, according to a study published on Thursday, a finding that could prompt scientists to redefine their worst-case scenario as they assess the effects of climate change. The rate of ice loss had slowed for a two-year period amid cooler...
Did you know that lightning sprites – like the one captured in the image above – exist above some thunderstorms? Sprites aren’t terribly well known, except to meteorologists, nature photographers and others who study the skies. They aren’t especially rare, but they’re fleeting. They’re not easy to capture on...
Remember that time you were out with some friends and tripped on a curb, but it definitely had nothing to do with the fact that you’d been drinking all night because you’re just clumsy all the time? Your phone knew it was the booze. But imagine if instead of just...
Google is celebrating the 190th birthday of the chemist and writer Julius Lothar Meyer with a Doodle depicting him experimenting in the lab to a backdrop of his vertical display of elements. Meyer was the son of a doctor from Varel in Germany. He qualified in medicine himself in 1854...
For years, scientists have been attempting to track an extremely rare “boomerang” earthquake. Now, they’ve recorded one in the ocean for the first time - and it’s even more bizarre than they expected. Earthquakes are the result of rocks breaking on a fault, which is a boundary between two plates....
