A spiral galaxy from the Galaxy Zoo: Hubble project, classified by 47 volunteers.
A spiral galaxy, observed with the Hubble Space Telescope in the COSMOS survey.
It is at redshift 0.38 (lookback time 4.26 billion years) with coordinates (150.63808, 2.06658).
47 volunteers classified this galaxy in Galaxy Zoo: Hubble.
No, particle physics colliders cannot ever destroy the Universe
Every time we push the energy frontier in particle physics, laypersons fear that the world, or even the Universe, will be destroyed.
Here's why we're certain it's all safe... for now.

Can we see the expanding Universe changing?
#AskEthan
We've measured the expanding Universe by looking at many objects at different distances and with different redshifts.
Here's how we'll measure it directly: with just one object over time.

Charles Darwin was born #OnThisDay in 1809. For all that his ideas became foundational science, he said remarkably little about humans--but as we have studied ourselves, we've discovered a remarkable evolutionary tale
Holy moly. Show this to anyone who says, "Wow, it's cold. So much for global warming!"
NASA's Day of Remembrance honors the brave astronauts who gave their lives in service to space exploration and the pursuit of knowledge.
The crews of Apollo 1, Challenger, and Columbia believed in something larger than themselves.
Yes, I am here!
yo no propuse ninguna tecnología. Propuse solo una posible geometría del espacio-tiempo. En la que yo propuse no hay dilatación del tiempo por construcción. Pero eso solo lo hice por simplicidad, no porque yo crea que sea realista en ningún sentido.

From our family to yours, merry Christmas! We hope your day is filled with good people and good food.
Merry Christmas! Michelle and I hope you have a wonderful holiday filled with light and joy.
The New Scientist Book Club is currently reading Iain M. Banks's classic sci-fi novel The Player of Games. In this extract, we meet protagonist Gurgeh for the first time
Totally agree!
I get at least one of those every day now. Sometimes as much as 10 in a single weekend. And yes, many of them start by saying that they discussed their ideas with an AI and it validated them (of course). It is getting worse.

El premio Nobel de física este año va para el descubrimiento de efectos cuánticos en sistemas electrónicos macroscópicos. Es decir, que ciertos efectos cuánticos pueden aparecer en sistemas compuestos de millones de partículas a la vez, y no solo en sistemas de pocas partículas.
"For every 1,000 measles cases, there are between 1 and 3 deaths from breathing complications or brain swelling. If there are a million cases, that’s about 1,000 deaths that doctors consider preventable with the use of vaccines"
Also: about 200,000 hospitalized (1 in 5 cases in unvaccinated people)
I am such a sucker for pics of Earth and the Moon taken from deep space missions. This one from Psyche, when it was *290 million km* from our planet, really puts things in perspective.
Here's my take on it 👇

Hey cool, astronomers found a new moon of Uranus (steady there, jokesters) in JWST images of the planet!

I bet it's been a while since you've had your mind vaporized by a JWST image so here's one of a cluster of galaxies so immense it's visibly warping space.
Bonus: I explain what you're seeing! Because that's kinda my thing!

Una entrevista en profundidad con Miguel Alcubierre donde se discuten las tripas de la Relatividad General. Tal vez te sorprenda esta entrevista más allá de burbujas.
Gracias a @miguelalcubierre.bsky.social por su tiempo y por su forma de hablar de Física. Ha sido un placer.

This is an article I wish I could've written, but halfway through it would've been laden with cursing and random letters as I pounded on my keyboard with my fists.
Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month features a rare cosmic phenomenon called an Einstein ring. What at first appears to be a single, strangely shaped galaxy is actually two galaxies that are separated by a large distance. The closer foreground galaxy sits at the center of the image, while the more distant background galaxy appears to be wrapped around the closer galaxy, forming a ring.
I look at a lot of space images, but this one made my eyes bug out like a cartoon character.
What you see here isn't a spiral galaxy, exactly. It's a spiral galaxy bent into a circle by the gravity of an elliptical galaxy at the center of the bullseye. Warped space! 🧪🔭

There's a #LunarEclipse tonight! If you're in the dark region here, and if you have a view of the Moon at the right time, you'll see the eclipse. Check www.timeanddate.com/eclipse/luna... for more info and timings for the eclipse in your location. (Here on the East Coast, totality peaks around 3am.)
