anybody else finding themselves going back to look at the intricate details of the #JWST images?
Sorry, I know some of you are maybe bored with this, but I keep seeing new things!
Like, I never paid attention before, but the tree-ring like structures of the planetary nebula!
Or what looks like that thin dust line, in the edge on spiral galaxy behind the planetary nebula.
You can see its core hub region. This reminds me of the needle galaxy a lot!
And this galaxy, in Stephan's Quintet .... how you can see the individual sources of light (?), and how its central supermassive black hole is nowhere near as bright as the other galaxies, even though the other galaxies are many times further away.
I know a few people were pretty shitty about the first JWST image going out early (they have reasons, I get it), but seeing the reactions to this vid (check out the QTs and replies) has really got LOTS of folks talking and thinking about our place in the Universe - this is good!
Each galaxies with hundreds of billions of stars. The curved arcs are of galaxies that are even further behind, that the foreground galaxy's gravity warps and bends their light to us.
So friggen beautiful.

I love you distant warped spiral and I will avenge you.
I was speaking to my mum today, she is getting ready for 2nd jab next week. They're all in Fairfield.
I asked her how the mood was out there ... and encouragingly she said that it's done a 180-flip ... people are wanting/rushing to book themselves in for the vaccine ASAP.

I asked her why, what changed?
She said the biggest motivator for the people she was speaking to was the notion that the double-vaxxed would be able to go to do things, go to shops, etc. over those who were not vaxxed.
It's a HUGE motivator out there IMO.

I know there are complexities with this strategy (e.g., privilege access to health, location, vaccine availability, etc.) but mum reckons, well at least for Fairfield and at least amongst her large community network - that this changed people's minds quicksmart.

so many of you have heard me go on and on about the Lunar far side, and preserving this as a site of importance heritage for a number of reasons, but in particular for the purpose of #RadioAstronomy ...
If not, here's a couple of quick tweets as a recap ...
Due to the axial rotation and orbit of the Moon, the same side normally faces the Earth. This is called the near side. Which means there is a far side as well, the face that we don't see because it always faces away from the Earth.
And while we're on the topic of #Pulsars, an exciting thing happened in the last few days ... the relatively nearby #VelaPulsar happened to glitch again!
Vela is known to glitch every 2.5-3 years, so let's dig in with a short thread on why this is exciting.
Steve runs the Hawkesbury Radio Observatory just near Sydney.
Steve (@Hawk_RAO) is no stranger to using his home radio observatory set up of Yagis to detect pulsars and has previously detected a Vela pulsar glitch in the past!
