New Evidence Adds to Findings Hinting at Network of Caves on Moon

NeRD

These images from NASA’s LRO spacecraft show a collection of pits detected on the Moon. Each image covers an area about 728 feet wide. An international team of scientists using data from NASA’s LRO (Lunar Reconnaissance Orbiter) has discovered evidence of caves beneath the Moon’s surface. In re-analyzing radar data collected by LRO’s Mini-RF (Miniature Radio-Frequency) instrument in 2010, the team found evidence of a cave extending more than 200 feet from the base of a pit. The pit is located 230 miles northeast of the first human landing site on…

‘Star Wars: The Acolyte’ episode 8: How open-ended is the conclusion?

NeRD

The twisty mystery of season 1 of The Acolyte wasn’t a ‘whodunit’ after all, but focused on why the murders were happening instead. While the first half of the season felt underbaked, it was episode 5 that turned things around, with the following two chapters doing most of the season’s compelling character and thematic work. Last week in episode 7, we finally found out what really transpired on Brendok 16 years before the main events of the series. Now, the finale closes that story arc, gives some characters closure, and…

In a new study, data from the James Webb Space Telescope reveals details of this mysterious gas giant exoplanet, which orbits a star about 700 light-years away from Earth. WASP-39 b is tidally locked to that star, which means the same side of the planet always faces its star. In other words, half of the planet experiences perpetual day, and the other experiences perpetual night. But the dividing line isn’t black and white — there’s a…
