A binary black hole merger likely produced gravitational waves equal to the energy of eight suns.
For all its vast emptiness, the universe is humming with activity in the form of gravitational waves. Produced by extreme astrophysical phenomena, these reverberations ripple forth and shake the fabric of space-time, like the...
Melting glaciers have increased the volume of glacial lakes by 50% in just 30 years, Scientists have found.
A new study led by Dr. Dan Shugar, PhD, with collaborators from governments and universities in Canada, the United States and United Kingdom, uses satellite data from NASA and Google Earth...
In a study published in PNAS, researchers used conservation biology and genomics to discover that the New Guinea singing dog, thought to be extinct for 50 years, still thrives. Scientists found that the ancestral dog population still stealthily wanders in the Highlands of New Guinea. This finding opens new...
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...
