Researchers from the Chinese Academy of Sciences, China’s Institute of Geochemistry and other organizations worked together to compile all known information about the moon’s surface in a new project that culminated in the most detailed map of the moon ever created. Using a 1:2,500,000 scale, the map denotes all discovered rocks, craters, basins and 90 different types of structures on the lunar surface. This is …
A fast radio burst (FRB) is “a transient radio pulse of length ranging from a fraction of a millisecond to a few milliseconds” from high-energy astrophysical activity of unknown origins. The first FRB was discovered in 2007 (by Duncan Lorimer and his student David Narkevic) but there have been many since then—and one especially active burst pulsates every 16.35 days. Recently, another highly active FRB, …
On 15 August 1977 at 10:16PM EST, Ohio State University’s Big Ear radio telescope scanned the Sagittarius constellation and detected a signal that was 20 times stronger than average, background emissions. When astronomer Jerry Ehman reviewed the findings the next morning, he wrote “Wow!” next to it, unknowingly naming the signal and its subsequent mystery. Since its discovery, scientists have not been able to determine …
