Dormant for 800 Million Years, Colossal Structures Have Been Uncovered Beneath China’s Surface That Could Rewrite Earth’s Early History  The Daily Galaxy Source link

NASA’s Perseverance rover stumbled upon an unusual find during its latest sweep of Mars, as the space agency shared a photo of a curious rock found on the red planet’s surface which looks exactly like a wide-brimmed hat. The rock, which appears to have a pointed-peak and wide brim, much like a witches hat or an old helmet, was selected …

NASA’s Perseverance rover has added to its trove of curious finds, as the space agency published a photo of a rock on the surface of Mars that looks like a centuries-old helmet. The rock has a pointed peak, a flared “brim,” and textures that could lead reasonable observers to compare it to a witch’s hat or a tent. The texture …

Scientists have figured out how to make frozen discs of ice self-propel across a patterned metal surface, according to a new paper published in the journal ACS Applied Materials and Interfaces. It’s the latest breakthrough to come out of the Virginia Tech lab of mechanical engineer Jonathan Boreyko. A few years ago, Boreyko’s lab experimentally demonstrated a three-phase Leidenfrost effect …

Ever since he transferred to the University of Oklahoma last winter, scrutiny has followed John Mateer for how the quarterback, rated one of the best in college football, would perform on the field. This week, Mateer has found himself under the spotlight for different reasons after screenshots from his personal Venmo account surfaced on social media showing two transactions labeled …

For more than 20 years, the European Space Agency’s (ESA) Mars Express orbiter has been imaging the surface of the Red Planet. One region, in particular, continues to fascinate the Mars Express team, known as Acheron Fossae. A new high-resolution photo examines the western edge of this region, giving us a closer look at the fascinating topography found here. Acheron …

The sun never sits still, yet until recently our best snapshots blurred its fine threads. Now an image set from the Daniel K. Inouye Solar Telescope on Haleakalā resolves details just 20 kilometers wide, letting researchers watch bright and dark stripes move across the solar surface. “We investigate the fine-scale structure of the solar surface for the first time with …

What impressed the scientists the most, though, was the versatility of those disks. Reef-associated species of remora like Phtheirichthys lineatus are generalists and stick to various hosts, including other fish, sharks, or turtles. Other species living in the open sea are more specialized and attach to cetaceans, swordfish, or marlins. While most remoras attach to the external tissue of their …

A hidden lake beneath the Greenland ice sheet at Harder Glacier suddenly burst from deep beneath the ice. The water exploded upwards, cracked the thick ice above, and shot out across the surface. In just ten days, the lake released 23.8 billion gallons (90 million cubic meters) of water. That’s the equivalent of nine hours of Niagara Falls water pressure …
