When it comes to going out with style, nothing comes close to the end of a white dwarf. Their thermonuclear self-destruction ranks among the most powerful explosions in the cosmos, forcing the star to wink out of existence in a blaze of glory. At least, that’s the idea. Discovery confirms some white dwarfs fake their … Read more
The Celestron Advanced VX 8-inch EdgeHD is a telescope system for intermediate to advanced versatile amateur astronomers, but still small and lightweight enough to transport easily for observing out in the country. The 8-inch aperture is enough to view and photograph all types of celestial objects, and the computerized equatorial mount makes it easy to … Read more

The closest approach took place at 09:44 UTC (11:44 CEST) on 23 June 2022, about 200 km above the planet’s surface. … Read more
The blue path illustrates a core-penetrating seismic wave moving through a region in the outer core, where the seismic speed has increased because a low-density flow has moved into the region.

Solar twister! Incredible footage shows 12,000-mile plasma TORNADO erupting from the surface of the sun A 12,000-mile-tall solar twister has been spotted by an astrophotographer Space weather experts say it was ‘big enough to swallow Earth’ if it was closer It is formed from a mass of plasma erupting up a helical magnetic structure The … Read more
Drawing of an octopus. Credit: Gloria Ros The octopus is an exceptional organism with an extremely complex brain and cognitive abilities that are unique among invertebrates. So much so that in some ways it has more in common with vertebrates than with invertebrates. The neural and cognitive complexity of these animals could originate from a … Read more
On a spring evening in 2015, Geralyn Ritter sprinted through Philadelphia’s 30th Street Station to catch her New York-bound train. The next thing she knew, she was hooked up to a ventilator at Penn Presbyterian Medical Center, fighting for her life. “I remember a flash of realization that we were tipping over, and I remember … Read more
This artist’s illustration imagines a violent collision early in Psyche’s history. Credit: ASU/Peter Rubin mars for a gravity assist on the way there, takes incredible precision. We must get it right. Hundreds of people have put remarkable effort into Psyche during this pandemic, and the work will continue as the complex flight software is thoroughly … Read more
Once again, life has been found in an environment that would be deeply inhospitable to most organisms living on this planet. Fed by waters that pass through 600 meters (1,970 ft) of permafrost, the sub-zero, salty, virtually oxygen-free Lost Hammer Spring in the Canadian Arctic is one of the harshest places on Earth. Even here, … Read more
A Jurassic vampire squid-like creature used supersuckers to snatch prey out of the water column and lock it in place with a watertight seal, 3D imaging of several fossils reveals. For the first time, scientists used advanced 3D imaging techniques to examine in great detail the prey-snatching suckers of Vampyronassa rhodanica, an extinct relative of … Read more
