Ars Technica: China’s lander releases data, high-resolution images of the Moon. “A little more than one year ago, China’s Chang’e 4 spacecraft landed on the far side of the Moon. In doing so, it became the first-ever vehicle to make a soft landing on the side of the Moon facing away from Earth. To mark the one-year anniversary, China released a batch of scientific data and images captured by five scientific payloads aboard the 1.2-ton spacecraft and its small Yutu 2 rover.”
Hubble Space Telescope: Announcing the Hubble Space Telescope Hidden Gems. “In April 2020, the NASA/ESA Hubble Space Telescope will celebrate 30 years since its launch. ESA/Hubble has produced a commemorative calendar of the telescope’s Hidden Gems that is now available for everyone to use and enjoy.”
Ars Technica: Finding stars that vanished—by scouring old photos. “Before the advent of digital imaging, astronomy was done using photographic plates. The results look a bit like biology experiments gone bad (of which I’ve perpetrated more than a few), with a sea of dark speckles of different intensities scattered randomly about. To separate the real stars from any noise, astronomers would take multiple images, often at different colors, and analyze the results by eye before labeling anything an actual star. Sounds tough, but by 50 years ago, astronomers had already managed to catalog hundreds of millions of stars in all areas of the sky.”
CNET: Watch a ‘potentially hazardous’ asteroid fly by Earth live on Friday. “Asteroids are zipping past Earth all the time, but we’ve got a special one coming up. Asteroid 1998 HL1 will be visible to some amateur telescopes, but you can look to the Virtual Telescope Project to bring it right to your eyeballs with a livestream on Friday starting at 10 a.m. PT.”
University of Arkansas: Textbooks by University of Arkansas Faculty Added to Open Textbook Library. “Three openly licensed textbooks written by University of Arkansas faculty are now available in the Open Textbook Library.” The new textbooks cover physics, astronomy, and technical writing.
Air & Space Magazine: Girl Scouts, Now You Can Earn a Badge in Space Science. “The Girl Scouts was just a year old when, in 1913, it began awarding badges to young women for electronics and aviation. More than a century later, it is challenging members to aim even higher, with the release this summer of three new space science badges encouraging girls to learn about astronomy and the exploration of other worlds.”
State of the Planet / Columbia University: Rescuing 50 Years of Apollo Sample Data . “Over the next five years, the Astromaterials Data System will collect, organize, and digitize study results not only from the samples collected by the Apollo missions, but also studies based on meteorites, cosmic dust samples, and samples from asteroids and comets gathered from outer space.”
