SpaceX on twitter: Ship 25 completed a flight-like chill and spin of the Raptor engine pumps, stopping just before engine ignition. As a result of the test, cryogenic liquid oxygen formed a visible cloud beneath the ship. This checked out vital systems in advance of the upcoming static fire.

Should r/Astronomy Remain Open?

Greetings r/astronomy, In response to Reddit's recent policy change, charging third parties for usage of their API, many third party apps used for browsing Reddit have been forced to shut down. In response, r/Astronomy joined thousands of subs in a protest by changing the sub to private. In response, Reddit has gone back on their word to not punish subs and mods that do this and are in the works of removing mods that refuse to reopen their sub. As mods of the sub, we have decided to invite members of the sub to submit their feedback on what they think the appropriate response from r/astronomy should be. Please use the poll to vote and leave further thoughts and ideas in the comments. [View Poll](https://www.reddit.com/poll/14gg676)

Milky Way over Badwater Basin in Death Valley National Park

What are these green stripes in the sky (near bottom left of sky in photo)? Taken last night in Canyonlands National Park.

I talked to the rangers and they doubted light pollution on clouds because “there is no light pollution in the area” (near islands in the sky). I’ve also never seen green light pollution on clouds. It’s not an issue with my camera as I shot the same thing later that night and nights before with this showing up and all the photos I shot during this time have them and I could see them faintly with my naked eye. Other thought was maybe some kind of aurora / solar storm but I think I’m too far south and the rangers are unaware of any event. The RAW file had them even more green. Any ideas? Thanks
