oo, there's also a @deepspace.social

choices!

I'm trying to move from @geckzilla to @spacegeck, but I requested my archive last night from @mastodon.social and it still says "compiling" this morning. I'm not hopeful! Might just have to redo follows and stuff.

Pretty cool to have an actual active timeline over here on Mastodon now. From the ashes rises a pachyderm?

Blink animation.

I've been slowly working on some of these Orion filters. Haven't had a lot of time recently, but here is an unfinished JWST composite aligned over an older HST composite I made a while back.

I'm officially flu vaccinated and new covid boosterized. 😁

What's causing that movement? Some newly formed stars to the upper right are emitting stellar winds which blow around any gas or dust they collide with. Also see Tom Haworth's thread on how proplyds are affected by intense radiation from massive stars:

“A bit of fun with the new JWST observations towards Orion from the PDRs4All team @OliBerne @NASAWebb. At first glance, these look like some quite oddball proplyds. Why odd? They are pointing in opposite directions. 1/7 (also maybe interesting to @markmccaughrean)”

Here's another proplyd. In this animation you can also see parts of the nebula have moved in the years that have passed since HST took its observations. That's quite a bit of movement.
