Have you ever heard of Betty Webster? I hadn't until recently, and she co-discovered the first black hole ever found! Here's her story, to honor her memory and fantastic accomplishment.

As of this morning, Starbucks workers across the country are officially ON STRIKE. And we're prepared for this to become the biggest and longest ULP strike in Starbucks history.

Say #NoContractNoCoffee with us: DON'T BUY STARBUCKS for the duration of our open-ended ULP strike! $SBUX
Don't Buy Starbucks! At any location, today and beyond, while workers are on ULP strike!

📣 For the first time ever, scientists have confirmed seeing a giant explosion on a star other than our own!

Our XMM-Newton observatory and the LOFAR telescope contributed to making this long sought-after discovery 👉 www.esa.int/Science_Expl...

🔭 🧪 ☄️ ☀️ 1/
An artist’s impression of a large red star releasing a bright, explosive burst of light. Swirling red and orange patterns surround the star, suggesting intense activity. In the background, a smaller blue planet appears with a faint, wispy trail extending away from it, indicating its atmosphere being blown off. The scene is set against a dark space backdrop dotted with stars.

Celebrated my first Halloween in the states with folks at @nuciera.bsky.social 🧡✨

Looks like I came back from a trip…

I’ll note my previous place of employment was in France 🇫🇷 #HappyHalloween! 🎃
Shanika dressed up as a “Louvre Jewellery Robber” wearing a crown, black beanie, black face mask, neon yellow safety vest, and black clothes poses indoors holding a black tote bag that says “UNTITLED COLLECTION OF OBJECTS”. They are in an office environment. A black tote bag with white text reading “untitled collection of objects“ is laid flat, topped with a jewel crown. In front of it there are two small white drawstring pouches and an arrangement of large and small emeralds spread out decoratively on a table, somewhat resembling a broken down necklace. A hand holds a small white drawstring pouch over a table scattered with emeralds (possibly broken off some stolen Louvre jewellery) and printed Halloween notes reading, “You are an awesome colleague! Have a Fab-boo-lous HALLOWEEN.” But the word colleague is strikes out and replaced with accomplice. A black tote bag with white text reading “UNTITLED COLLECTION OF OBJECTS” sits on a table with a jeweled gold crown resting on top. In front of the bag, there’s a hand pointing to a hand-drawn floor map labeled “THE LOUVRE” and “1ST FLOOR,” with handwritten notes marking places like “Apollo Gallery” and “Napoleon III apartments.” A person (Shanika) is pointing to the Apollo Gallery and has labelled it with “Enter here”

We are pleased to announce our discovery of #GW241011 and #GW241110

Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger?

Infographic about GW241011 and GW241110 GW241011's source contained black holes about 13 and 8 times the mass of our Sun. The spin of the bigger black hole is high and bear aligned with the orbit. GW241110's source contained black holes about 17 and 8 times the mass of our Sun. The spin of the larger black hole is high and near anti-aligned with the orbit.

Red Spider Nebula, caught by Webb 🕸️

🕷️ Planetary nebulae like this cosmic creepy-crawly form when stars like the Sun reach the end of their lives, balloon into cool red giants & shed their outer layers 👉 www.esa.int/ESA_Multimed...
🧪 🔭
A large planetary nebula. The nebula’s central star is hidden by a blotchy pinkish cloud of dust. A strong red light radiates from this area, illuminating the nearby dust. Two large loops extend diagonally away from the centre, formed of thin ridges of molecular gas, here coloured blue. A huge number of bright, whitish stars cover the background, also easily visible through the thin dust layers. Credit: ESA/Webb, NASA & CSA, J. H. Kastner (Rochester Institute of Technology)

Macroscopic quantum tunneling wins 2025’s Nobel Prize in physics

This year's Nobel Prize in physics was all about building the first sustainable macroscopic system to exhibit quantum behavior.

Here's the science behind the prize, and why it matters.

Interested in research based on our archive data?

Then the ESA Archival Research Visitor Programme might be for you.

The next deadline for applications is 10 November 2025. Check out all the application details here 👉 www.cosmos.esa.int/web/esdc/vis... ☄️ 🧪 🔭
Illustration promoting the Archival Research Visitor Programme and the next deadline date of 10 November 2025. In the background, a model image of what our home galaxy, the Milky Way, might look like face-on: as viewed from above the disc of the galaxy, with its spiral arms and bulge in full view. In the centre of the galaxy, the bulge shines as a hazy oval, emitting a faint golden gleam. Starting at the central bulge, several glistening spiral arms coil outwards, creating a perfectly circle-shaped spiral. They give the impression of someone having sprinkled pastel purple glitter on the pitch-black background, in the shape of sparkling, curled-up snakes.

How and when will the Universe die?

#AskEthan

Ever since the discovery of dark energy, astronomers have been secure in predicting the heat death of our Universe.

But if dark energy is changing, as DESI data suggests, are all bets off?

Ask Ethan: How and when will the Universe die?
As the Universe ages, it continues to gravitate, form stars, and expand. And yet, all this will someday end. Do we finally understand how?

🆕 The discovery of new complex organic molecules at Saturn's #Enceladus enhances the likelihood that the moon is habitable 🪐

On Earth, these molecules are involved in chemical reaction chains that lead to the more complex molecules essential for life.
