The Discussion: Our dark sky practical astronomy event, AstroCamp Farewell Apollo 7's Walt Cunningham Comet C2022 E3 ZTF reaches naked eye brightness     The News: Rounding up the astronomy news in February, we have: Incredible finding: stars have not always been made the same way throughout the history of the Universe The debacle of the first space launch from UK soil 3 rocky water worlds found by the Kepler Space Telescope The big news story: a decade-long study finds light pollution is worse than we thought   The Sky Guide: This month we're taking a look at the large winter constellation of Ursa Major with a guide to its history, how to find it, a few deep sky objects to seek out and a round-up of the solar system views on offer in February.   Q&A: Does the James Webb Space Telescope have to take calibration frames like I do from Earth - darks, flats, and bias frames to then stack?
