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!
Had a weird experience at a cafe at a town on the way. Big sign before we walked in:

“IF YOU’RE FROM SYDNEY YOU ARE NOT ALLOWED TO COME INTO OUR STORE”

Seemed a bit OTT, esp. given we had masks, hand sanitizer, and made sure we were not over capacity in store ...
I know this Covid stuff is scary AF, but it’s probably best to avoid creating “us vs. them” cultures that will make recovery difficult and start applying situational management / decision making based on risk.

The entire population of Sydney (5M people) is not infected.
Of course, we complied and went on our way (all we wanted was a soft drink!) .... but harms the business to be like that IMO.

Not their fault though ... is a downstream outcome of loads of misinformation that has been spread into towns and communities. Rather sad, actually.
Anyway, we didn’t mind ... was just weird .... about to grab a bite to eat before the magic show in the sky commences!

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!

Some upfront stuff (cause Lord knows you need it on this site in 2021):

- Not representing views of anyone here, just my own research project for Uni
- If I make a mistake, feel free to let me know, i'm still learning this stuff
- Long thread, so mute #PulsarSSB if you want now

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!
But here it is! The Centaurus A Galaxy! (NGC 5128).

This Galaxy was discovered in 1826 by James Dunlop in Parramatta, NSW.

It contains a supermassive black hole as massive as 55 million Suns!

And besides it’s visible structure, it has a HUGE radio signature!

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)
Which I think is actually rather exciting in itself .... the ability to see the variability in the star's light using our eyes as instruments.

In fact, just a few weeks back, this was the EXACT topic of my essay (major project) for my History of Astronomy subject!
