And Hubble has been making history ever since! 🔭

A logo "HSLA" which stands for Hubble Spectroscopic Legacy Archive, has three stylized spectra with rainbow colors radiating from left to right. In the background are stars, galaxies, and a giant planet.

Hey #astrosci community! After working on this project for 3 years, there's a new Hubble Spectroscopic Legacy Archive that's just been newly made available at @stsci.edu: archive.stsci.edu/missions-and... follow me to learn more! (1/n)

War ravaged Portland.

Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪

Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students.

I wrote this little profile to mark the 100th anniversary of her thesis:

The first billion years according to JWST - Nature Astronomy The infrared view of JWST has opened up the early Universe to study. This Perspective summarizes the key developments in our understanding of the high-redshift Universe from the first 18 months of JWS...

It's also amazing to think that JWST has revealed so much new about the first-billion years of our Universe.
Anyway the discussions led to the below Nature Astronomy paper!

Say Cheese. 🧀 It's time for your official Symposium photo.

In fact, Swiss cheese reminds us of the galaxies, clusters, filaments, and holes that make up our Universe.

I need this book! Lol 😅🤣😂

My mind is absolutely blown by these stellar halos nearby NGC 4364!

The Roman core community surveys and Galactic Plane Survey are going to be absolutely bonkers. You can read more about some of these here: arxiv.org/abs/2505.10574

I'm so privileged to have worked on this mission for 2.5 yrs! #astrosci 🧪☄️🔭

JWST’s most ambitious view is now available to everyone The COSMOS-Web survey is now complete, combining JWST and Hubble infrared data. Its spectacular views show us the Universe as never before.

Been an exciting week for @galaxyzoo.org - our relaunch with JWST imaging has resulted in highest daily classification rate since March 2020. www.galaxyzoo.org. 🔭👩‍🔬🎉

I came up with a somewhat unusual theory — published today — for why JWST is seeing surprisingly bright galaxies in the early Universe: it's due to dark matter. [1/n] 🧪

Jeremiah Ostriker, Who Plumbed Dark Forces That Shape Universe, Dies at 86 There’s more to the universe than meets the eye, he found. His studies led astronomy to the dark side, changing our view of what’s out there.

CHILES IX: Observational and Simulated HI Content and Star Formation of Blue Galaxies in Different Cosmic Web Environments We examine the redshift evolution of the relationship between the neutral atomic hydrogen ({\HI}) content and star-formation properties of blue galaxies, along with their location in the cosmic web. U...

Happy to announce our accepted paper on the HI and star formation in simulated and observed galaxies in different cosmic environments is now on ArXiV!

The NASA Hubble Fellowship Program recently named 24 new fellows to its 2025 class. The program enables outstanding postdoctoral scientists to pursue independent research in any area of NASA astrophysics: bit.ly/4c2ZJpI 🔭 🧵

star light is supposed to be cool and romantic not to be cross dispersed H is a letter not an element wanna know something? don’t! i’m using iraf to manually measure the line width of that calcium h emission this is a nonsensical statement made by r deranged people look at what spectroscopists have been demanding your respect for after all the red lights we put in their observatories this is real astronomy done by real astronomers if spectroscopy was real how come no one thought of flipper? they have played us for absolute fools

STOP doing SPECTROSCOPY

Gonna use no. 46 😉

Happy birthday!!

JUST RELEASED: DESI DR1 & BAO RESULTS FROM DR2🌌

There is a global climate catastrophe underway, multiple genocides happening, a housing and unhoused people crisis, a child poverty crisis, people are struggling to afford food and what are moderate Democrats and GOP concerned about?
