The arcs around the two galaxies in the centre of this Hubble image are caused by the light from galaxies behind the galaxy cluster in the centre being bent by the gravity of the cluster. This is gravitational lensing.

M17- the Omega or Swan Nebula is a star formation region about 5000ly from us. It glows red because the young stars excite the gas of the nebula.

I'm sad that Mastodon seems to be getting more and more passive-aggressive and mean-spiritedly cliquish as time goes on. It's starting to feel like the worst of Tumblr culture in a lot of ways. Over the last few days I've pre-emptively muted notifications for several posts because I can predict the replies I'm going to get and I'd rather not see them.

I don't think it has to be that way. I think we can all do better. Exercise compassion for others, and maybe think twice about our next subtoots.

Planetary nebulae are generally round/elliptical or bipolar-butterfly shaped.
We don't know exactly what the collimation mechanism is for the bipolar PNe. (Left my image of M97, right Hubble image of M2-9)

This shot of M101 is from the @RAOastronomy Baker-Nunn telescope. M101 is visible below centre. The arrows point to other galaxies that I was able to identify in the image.

Having my long-term goals (ie 30 years) etc has helped build optimism.

> Through employment of specific coping strategies, optimism exerts an indirect influence also on the quality of life.

Harl on Byzantium, 2. How to account for the appeal of Christianity to Constantine and his Roman contemporaries? The Romans had a warrior ethic, trained, by spectacles of cruelty, to identify with the victor. The image of the Passion offered an alternative: identifying with the suffering of the victim.
