“#What kind of bee is that bee? Exotic Bee ID website expanded” Credit: CC0 Public Domain Exotic Bee ID, a website created through a collaborative effort between the U.S. Department of Agriculture’s Agricultural Research Service (ARS) and Animal and Plant Health Inspection Service (APHIS) and Utah State University (USU) to help identify non-native bees in…
“#NRL telescope onboard SOHO discovers 4000th comet” Courtesy Photo | The 4,000th comet discovered by ESA (European Space Agency) and NASA’s SOHO observatory is seen here in an image from the spacecraft alongside SOHO’s 3,999th comet discovery. The two comets are relatively close at approximately 1 million miles apart, suggesting that they could have been…
