Researchers at the University of Bayreuth have created a form of nitrogen that’s never been seen before. Nicknamed “black nitrogen,” the new substance is crystalline, occurs in two-dimensional sheets, and could one day be useful in advanced electronics. From a report: Strangely enough, the idea that black nitrogen didn’t exist has long been considered a mystery. The periodic table is arranged…

The Galaxy’s Brightest Explosions Go Nuclear With an Unexpected Trigger
sciencehabit writes: Type Ia supernovae, a bright and long-lasting brand of stellar explosion, play a vital role in cosmic chemical manufacturing, forging in their fireballs most of the iron and other metals that pervade the universe. The explosions also serve as “standard candles,” assumed to shine with a predictable brightness. Their brightness as seen from Earth provides a cosmic yardstick, used…
Tunguska Meteor That Blasted Millions of Trees in 1908 Might Have Returned To Space
schwit1 quotes Space.com: A new explanation for a massive blast over a remote Siberian forest in 1908 is even stranger than the mysterious incident itself. Known as the Tunguska event, the blast flattened more than 80 million trees in seconds, over an area spanning nearly 800 square miles (2,000 square kilometers) — but left no crater. A meteor that exploded before…

Its…
Scientists puzzle over massive, never-before-seen star system in the Milky Way
Earlier this year, an international team of scientists announced the second detection of a gravitational-wave signal from the collision of two neutron stars. The event, called GW190425, is puzzling: The combined mass of the two neutron stars is greater than any other observed binary neutron star system. The combined mass is 3.4 times the mass of our sun.
