The #Artemis II crew are at the closest point to the Moon in their mission, also called the perilune 🌒

We are so, so small. #Artemis

The Artemis II crew will spend about six hours on Monday observing the moon. Here’s what they’ll be looking for

#Artemis II - Crew began mission day 4 prepping for their flyby. Tasks include a manual piloting demo with Victor Glover, reviewing lunar science targets, and collecting bio-samples. The Orion spacecraft remains on track for its flight around the Moon! 🚀🌕

Ask Ethan: Do gravitational waves redshift like light does? Light redshifts as it travels through the expanding Universe, and is affected by a host of other phenomena. But not everything is the same for gravitational waves. bigthink.com/starts-with-... #space #astro #cosmology

Yes, a base is the ultimate goal of the Artemis program. The plan: Artemis I: uncrewed, testing rocket ➡️Artemis II: crewed, testing rocket/systems Artemis III: crewed, testing rendezvous with lander Artemis IV: crewed, landing on Moon Artemis V: crewed, landing on Moon, beginning base construction

#Artemis II update: our European Service Module's main engine performed the translunar injection so precisely that flight controllers in Houston decided to cancel the first of three outbound trajectory correction burns on the way to the Moon 🥳

When the spaceship is performing even better than planned 💅🏼

NASA is targeting April 1 to launch a crew of four astronauts on a journey around the moon that will set the tone for the agency’s lunar exploration ambitions

“When homophobic hate comes my way and says, ‘Why did you have to make it a gay story?’ We say, ‘Because you ask questions like that. It’s not a gay story it’s a love story, you asshole” —Nick Offerman, his response to people bitching about his character being gay in The Last of Us.

Tras la muerte de Carl Sagan en 1996, su viuda Ann Druyan era preguntada a menudo por el ateísmo de su marido y si antes de su fallecimiento había asumido alguna creencia religiosa. Esta fue su respuesta:

Happy Pi Day!! Mark the occasion with some of our favorite stories about pi (and about pie), and share how you celebrate!

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. bigthink.com/starts-with-... #physics #astro

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. bigthink.com/starts-with-... #space #astro #redshift

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.

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 👇 badastronomy.beehiiv.com/p/a-portrait... 🧪🔭

Hey cool, astronomers found a new moon of Uranus (steady there, jokesters) in JWST images of the planet! science.nasa.gov/blogs/webb/2...

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! badastronomy.beehiiv.com/p/an-incredi... 🔭🧪

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.

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! 🧪🔭 esawebb.org/images/potm2...

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.)

New Pharaoh's tomb just dropped. The tomb of King Thutmose II has been uncovered, Egyptian officials announced on Tuesday, marking the first discovery of a royal resting place since King Tutankhamun’s was unearthed in 1922.
