In about a week, an important chapter in #RadioAstronomy and Australian space heritage, will come to a close.

The Molongolo Observatory, operating for 58 years and the last Mills Cross in Aust. will cease operations. 😭

A short thread ....

cc @drspacejunk

📸 UTMOST The Molonglo Observatory Synthesis Telescope (MOST) is an odd looking radio telescope, unlike the familiar dish antennas - it's two intersecting arms (N-S & E-W) that look like a half pipe and stretch for 1.6 km in each direction.

You can even see it on Google Maps, it's huge!

Look, I don’t mean to alarm anyone but those #JWST images of the ‘Pillars of Creation’ are now downloadable and public!

A little processing job I just did on them … gosh, these structures are glorious, aren’t they?!

Isn't this just bonkers?

A massive gamma-ray burst went off in space recently and it was so strong, that it ionised the upper parts of Earth's atmosphere, changing how radio waves propagate through it. Detectors in India, Germany and UK observed this change 👇

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! semi-circle nebulous structure showing a blue hollow-ish cor 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! an edge on spiral galaxy that looks like a narrow line of br

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! The main reactions have been:

"We are sooooo not alone in the Universe / there are aliens out there"

"Holy, shit, wow!"

"This is terrifying, we are so insignificant"

"We should stop fighting amongst ourselves, look at this perspective"

I mean, look at them.

Look at all of them.

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 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.

1/n 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.

Spending my Saturday night in doing research, and have just come across something I have been looking for, for some time now.

Kinda exciting to finally have it and read it in detail.

@drspacejunk knows I've been going on about this #RadioAstronomy topic for some time ...

🧵 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 ...

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.

But I heard about it through Pro-Am radio astronomer (and friend!) @hawk_RAO who picked it up early!

It truly is amazing that in a world awash with data of oceans warming, reefs bleaching and climate change amplifying - that the Environment Minister (and Govt.) would lobby (and obtain) support from 44 other countries to deny risk categorizing of one of our most precious assets. It’s bad enough when leaders sit on their hands and do nothing about climate change.

But when they actively go out of their way to ensure that the risks are not addressed appropriately for their own sinister (and greed-driven) purposes …. We’ll, that’s criminal.

ASTRONOMY DRAMA CIRCA 200 YEARS AGO.

Henry Bathurst had to get involved to resolve the beef between them.

He went back to EU and published a 12,000-star catalogue of southern skies in 1832.

I really love that saying/idiom:

“They saw you coming from a mile away”

It means:

‘see (one) coming’
To view someone as being particularly gullible and thus easy to deceive, swindle, or exploit.

On that note - I’m selling Jovian moons. $20 million starting price. I mean, this might get loads of people talking about WASP-127b at least …

The planet has a radius bigger than Jupiter (though, much less dense), was discovered in 2016 via transit method and orbits very close to its host star every four days.

We’ve arrived in Parkes ... and I seem to be getting notifications from December on here?!

The space-time continuum is warped here ... must be a local, massive object distorting the local gravitational field ....

Just scouting locations for tonight’s astrophotography! Popped into lovely Lithgow on the way for a bite to eat ....

I’m excited about the big blue skies out here!

Few days back the team from NANOGrav made an awesome announcement, up there with my studies & was similar subject to my last major research project for my #AstronomyMasters!  

A (very long) thread about pulsars + the Barycentre + gravitational waves coming your way! So, to begin, let me start by sharing this absolutely fantastic, balanced article by @riding_red about the announcement .... it's such a great article, and my supervisor from my last subject is quoted in there too!

Ok everyone, I'M REALLY SORRY but you're going to have to put up with a few tweets of my excitement right now ... as I have just come down from star-gazing and guess what ... I GOT MY SECOND GALAXY!

I've been after this one for about a year, so i've got tingly fingers et al.! So let me first do the standard disclaimers ... still learning, still not processing images properly (i.e. not doing darks, flats etc.), still only taking a few shots (30 exposures X ~0.5 secs each) .... so they are not the best, and kinda grainy ... but I'm totally ok with that!

I'm loving all the excitement around if Betelgeuse is about to go Supernova.

It really is a massive star and the explosion would be so friggen cool!

Here's the ALMA 'image' of Betelgeuse overlaid on our System - look how big it is!

Credit: Sci-News.com The reason for all the chatter - Betelgeuse has dimmed in brightness over the last few months.

So much so, it is said to be noticeable with our eyes (we've had lots of smoke in the air, so I haven't had a good look myself)
