Octopus DNA reveals Antarctic ice sheet is closer to collapse than previously thought: “Unstable house of cards”
The history of genetic mixing indicated WAIS collapsed at two separate points — first in the mid-Pliocene, 3-3.5 million years ago, which scientists were already confident about, and the last time in a period called the Last Interglacial, a warm spell …
Upcoming Einstein Probe will use its ‘lobster eye’ to hunt for extreme black holes and star explosions
A new space telescope set to launch in Jan. 2024 will look at the cosmos with a revolutionary “lobster eye,” hunting for X-ray bursts that stem from some of the universe’s most powerful phenomena, including feeding black holes, colliding neutron stars …
Octopus DNA seems to confirm scientists’ theory about a long-standing geological mystery
A study of octopus DNA may have solved an enduring mystery about when the rapidly melting West Antarctic ice sheet last collapsed, unlocking valuable information about how much future sea levels may rise in a warming climate.
Nuking an incoming asteroid will spew out X-rays. This new model shows what happens
Last year, a NASA mission proved that humans could change an asteroid’s course by crashing into one with a spacecraft. But if an impact alone is not enough, we do have at least one alternative option: nuking it. A new study, released after NASA’s …

Earth’s Inner Core Mysteriously Wobbles Every 8.5 Years, Likely Influencing How Its Magnetic Field Works!
Deep within Earth’s fiery heart, hidden behind layers of molten rock, a strange dance is taking place. Our planet’s inner core, a solid ball of iron larger than Pluto, isn’t just spinning — it’s wobbling, like a top losing its balance, in a cycle that …

Meet the Infrared Telescopes That Paved the Way for NASA’s Webb
The Webb telescope has opened a new window onto the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite. On Dec. 25, NASA will celebrate the two-year launch anniversary of the James Webb …
High-Flying Frigate Birds Collect Data from the Top of the Sky
Researchers have recently discovered — by chance — that great frigatebirds can collect helpful climate data as they traverse the high skies. They found that frigatebirds fly high enough to skim the edge of the planetary boundary layer …
The Year’s Most Spectacular Photos from the James Webb Telescope
At the center of the image is a horizontal orange cloud known as Herbig-Haro Close to 1,500 light years from Earth lie a pair of baby stellar twins known as Herbig-Haro 46/ …
