In addition to high #SolarFlare activity, there’s another thing to watch for on the Sun - a huge filament of plasma, arching through the Sun’s atmosphere. Should it erupt, the filament is currently in a prime location to impact Earth and trigger a geomagnetic storm! #spaceweather

Do you remember the (fantastic!) discovery of QUARTZ clouds on WASP-17b last year? nasa.gov/missions/web... Well, if you ask a geologist, they'll quickly tell you that such a thing doesn't make any sense. Quartz isn't stable at the high temperature conditions of hot Jupiters 2/n

This is the Dragon's Egg nebula (NGC 6164, NGC 6165). I captured the data in June 2023 10 hours Ha, 12 hours OIII, mixed HOO with replacement RGB stars. #astrophotography

The Cone Nebula in Monoceros. The shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing ionized hydrogen. The nebula is approximately seven light-years long and 2,700 light-years from Earth. LRGBHa. #astrophotography
