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.
Look, in the interest of transparency (which I think honesty always works best in these kinds of deals) here’s a bunch of data on this exoplanet, so now, you can own it too!
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!
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.
They’ll play some weird “China is trying to get back at us” card (or some other political angle) instead of just looking at the facts that seem to be abundant and available for all to access:
Researching about Karl Rümker (1788-1862) who got into a fight with Thomas Brisbane over 4 km^2 on the west side of the Nepean river in 1823.
Henry Bathurst had to get involved to resolve the beef between them.

Rümker eventually held the title of the Government's Astronomer here in NSW, observing lots of objects from the Parramatta observatory, incl. the rediscovery of Comet Encke in 1822.
He went back to EU and published a 12,000-star catalogue of southern skies in 1832.
Sounds like Rümker was into a bit of fisty cuffs given he got into yet another fight in England with President of the Royal Astronomical Society, James South, who banned him from working n British Govt. thereafter.
Mons Rümker, the lunar massif with 22 domes named after him.
Ohhhh, using seismic data (Marsquakes FTW!) observed by @NASAInSight - scientists have now measured the Martian core to be 1830 km with an error bar of ± 40km!
Unexpected rabbit hole of the Mars liquid core paper from this morning ... chasing down historical papers values of the mean core density (compared with the 5.7 to 6.3 g/cc reported) in reflection of JPLs ephemeris data (which also use Mars mass to establish Asteroid belt mass)
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
