A meme comparing a crappy car to a star cluster (obviously not crappy.) The meme concludes by soliciting DMs from any meme-viewers who want to know my favourite star clusters.

Thousands of asteroids and millions of galaxies shine in first images from the largest camera ever built | CNN The first test images from the Vera C. Rubin Observatory in Chile showcase thousands of previously unknown asteroids and millions of glittering galaxies.

that being said look at how absolutely stunning Rubin's view of our night sky is: www.cnn.com/2025/06/23/s...

"comparison is the thief of joy" tell yourself that BEFORE you start comparing my beautiful hubble telescope to your new gen fancy smancy telescope again. Think about how that would make her feel. She has been the greatest for the longest of time and we owe her the world

New age determination method if my cluster can open a child safety cap it is a young cluster otherwise it is an old cluster in this paper I will use

boxer ready to fight: ok ima accomplish a lot of things today. boxer sitting down: damn overlead down

it is a hint from the universe to go outside and sit in the sun

oversimplified: parallax to distance is a non-linear relationship, so a (symmetrical) error in parallax leads to an asymmetrical error in distance. This very nice paper by Bailer Jones describes the whole problem in detail: arxiv.org/pdf/1507.02105
or this one: arxiv.org/pdf/1804.09376

Screenshot from a spongebob scene: the blackboard says 'Good Noodles' with a list of people getting stars. "Everyone who does not just use 1/parallax to get the distance" got the most stars, because they are not just good noodles but the best.

Gaia spacecraft in space in front of the Milky Way galaxy

Today we say goodbye to ESA’s Milky Way-mapper Gaia! The Gaia spacecraft has completed its sky-scanning and will be switched off this morning.

no way pete hegseth just texted me the origin of the imf

why dont you go observe the way shear rips apart unbound groupings of stars and maybe then you'll calm down

being alive is great because there are so many colours you can try out in matplotlib. but then there is also the horrors

valentines card with: i want to measure all your angles

valentines card with: they cant accurately measure the radial velocity of my heart cuz it is spinning way too fast for you

valentines card with: are you HDBSCAN cuz you can locate my overdensities

valentines card with: i have your Gaia ID memorized

unmatched astrometrizz 💥💕send this to your boo

We propose a new age dating method for open clusters based on whether a cluster is able to open a child safety cap or not, assigning clusters the binary labels 'child' and 'adult'. In this paper we will

A meme titled "Think you have it hard? Imagine being 2MASS-GC01 WHEN WILL THIS CLASSIFICATION MADNESS END???"

Can't believe we're obsessed with classifying my beloved

the astro community posting their research here on bluesky is kinda like hanging assignments you are proud of on the fridge but virtual

no but in all seriousness B fields are cool! Very hard but cool. The Planck whole-sky map of the magnetic field is one of the coolest plots ever to come out of a digital survey (www.ias.u-psud.fr/soler/planck...)

and then those magnetic field enjoyers turn around and create galactic maps consisting of 18 differently oriented strokes only they can read

😔🤝 exactly!! Especially as an early stage researcher that is super hard to do, because it almost feels shameful but it is the exact opposite! Clear and healthy communication is so much more productive

one side has a huge hole I think someone reversed into me
