Every Easter I often think about the importance of astronomical observations and documentation from people who lived thousands of years ago, and how this shapes our traditions today. Understanding of the northern hemisphere vernal equinox by Mesopotamians drove a lot of what “Easter” is today.

Look at this excellent toy my friend got for his nieces and nephews for Easter. 13/10. NGL — will probably buy this for myself.

Friendly reminder to scientists/science communicators - the images you share (and thus grow followers, trust, credibility upon) are 100-fold better when you use alt-text because they are more accessible to broader audiences. Want to go one step further? Attribute the source! It's the BlueSky way.

Neil deGrasse Tyson went on Rogan which is a huge bummer but the good news is that there are lots of cool Black 🔭 #scicomm out there and @blackinastro.bsky.social even made a starter pack! 🧪https://go.bsky.app/6nFQdRC

The next “confirmed administrator” is slated to be Jared Isaacman. He’ll get to approve or alter the future direction of the space agency. So once again, what is Isaacman’s position on: - conflict of interest with Musk/SpaceX? - his autonomous decision making? - DEI at NASA? - existing programs?

'CosmicCon' would be the intersection of queerness and astronomy and everyone will wear a colour of their choice from the Progress Pride flag. We'll have topics of discussion that range from the arts, humanities and into sciences. Drag shows will be on during breaks. And an outdoor silent disco.

April 18 is World Heritage Day. In 2020, my fav telescope in the world — Murriyang (Parkes radio telescope) was heritage listed. Here’s an article I wrote about this wonderful instrument and its history in 2020 for @spaceaustralia.com www.spaceaustralia.com/news/astrono... 📸 CSIRO archives

Another recommended read from @teenvogue.com telling truths how they should be told 👇🏽👇🏽👇🏽 We’ve been continually led to believe that “terrorists” are only the Middle Eastern types, when in reality, in the US, it’s white males who fit the profile of a “terrorist” and are killing lots of people.

Inspired by JWST’s recent results on M83 (potential supermassive black hole) I set #SeestarS50 onto it last night from my backyard (3.5 hours of data). If you squint you can see the little pockets of glowing pink gas - stellar nurseries in the spiral arms of this nearby galaxy. #astrophotography

An old astronomer's joke: A UFO enthusiast calls an observatory. Says "there's this bright light in the sky near Orion." The astronomer says "Oh. That's Sirius." "What do you mean that's serious?" And so on.

Very SIRIUS. Very bright. #SeestarS50

Really think we could use moments like these ('biosignatures') to show how scientific ideas are proposed, tested, debated, and refined - to broader audiences. Whether we’re talking space, climate change, or pandemics, I think it's good to build trust with the public by showing this transparency.

Sarah’s rules of looking for life with only chemical signatures: 1) the smaller the molecule(s) the more likely they can also be produced by abiotic processes 2) one molecule, if it can be produced by any abiotic process, will never be enough to definitively claim detection of life

This thing that really gets me about all these people is that they have the money, they’ve got everything they need, just to go live a lavish, happy life and not care about anything. But they choose to invest and celebrate division and hate, using their resources to weaponise their bigot views.

New analysis using MIRI on #JWST of the nearby, face-on spiral galaxy, M83 (Southern Pinwheel) indicates that there now COULD be a supermassive black hole in its nucleus. Triangulum Galaxy, your turn next! iopscience.iop.org/article/10.3... 📸 me, backyard scope HT @esascience.bsky.social 🔭☄️

Remember when SpaceX was just a launch provider? Of course there is some shady deals with conflict of interest going on here. And another 1600 satellites in the sky — including weapons. If successful, this will place another piece of critical infrastructure in the hands of SpaceX (+ Palantir) 🚩

My recall is preliminary work on this result (and the theory/likelihood of Hycean worlds in general) was presented here in NZ in Christchurch/Ōtautahi last year during the ExSS V conference we hosted with AAS. It was sceptically received by the ~450 exoplanet folks then...

I think the thing I am most annoyed about right now is that this announcement could have waited until AFTER the Easter weekend break. I have to now deal with annoying cousins (who are Moon Landing truthers). They're gonna latch onto the 'alien' news from bad sources on Tik Tok or something lolsob

"This new independent evidence for the presence of DMS and/or DMDS at 2.9-3.2 σ adds to the tentative inference of DMS reported previously and bolsters the chances of a biosphere on K2-18 b" 3.2 σ .... more of an interesting suggestion IMHO!

LOL So, Helen is at the dentist, and already the news is blown out of proportion in Australia. Channel 9 News is one of the main news carriers in Australia. This is why we don't jump to conclusions. A whole lot of people are about to believe we found aliens, without the proper context. 🙄 🔭
