Physicists Have Observed a Strange New Kind of Transition in Electronic Crystals

by

As basic science teaches us, changes in temperature can result in phase transitions in materials – like when water solidifies as ice in the freezing cold. However, in some cases the temperature that triggers the change is different depending on whether the material is cooling down or warming up. This is known as a hysteresis … Read more

Earth’s Ancient ‘Supermountains’ May Have Been Crucial For Life as We Know It

by

Once, there were giants. Mountain ranges that rivaled the Himalayas in height used to stretch thousands upon thousands of kilometers across the seams of merging supercontinents, billions of years in the past.   Like the teeth of decrepit old gods, they’ve long been worn down to their roots by time and decay. But in those … Read more

Scientists discover lost range of ‘supermountains’ three times longer than the Himalayas

by

Twice in our planet’s history, colossal mountain ranges that towered as tall as the Himalayas and stretched thousands of miles farther reared their craggy heads out of the Earth, splitting ancient supercontinents in two. Geologists call them the “supermountains.” “There’s nothing like these two supermountains today,” Ziyi Zhu, a postdoctoral student at The Australian National … Read more

Astra scrubs 1st Florida launch attempt due to faulty ‘range asset’

by

Astra’s first launch of operational satellites will have to wait at least another day. The California company planned to launch the ELaNa 41 mission for NASA today (Feb. 5) from Florida’s Cape Canaveral Space Force Station but was thwarted by an issue at the launch range. “Unfortunately, due to a range asset that has gone … Read more

The ‘Somalaya Mountains’ Might Be The Biggest Mountain Range You’ll Never Get to See

by

Every geography schoolbook has them: maps that look like today’s Earth, but not quite, since all continents are merged into a single supercontinent. Those maps were used to explain why dinosaurs in South America and Africa, or North America and Europe looked so alike.   Paleogeographic reconstructions like these provide context to study the processes … Read more

Scientists Observed This Ghostly Galaxy For 40 Hours And Couldn’t Find Any Dark Matter

by

A new discovery has deepened the mystery of galaxies without dark matter. In a galaxy named AGC 114905, 250 million light-years away, astronomers could find no trace of the mysterious stuff, even after 40 hours of detailed observation and subsequent analysis.   The result, to be published in the Monthly Notices of the Royal Astronomical … Read more
