Meet our Solar System's newest dwarf planet candidate: 2026 ED138! Orbiting past Pluto, scientists found it in NSF–DOE Rubin Observatory data from earlier this year. Early analysis suggests it's ~600–1500 km across, one of the largest found past Neptune!🔭🧪 🔗: rubinobservatory.org/news/rubin-f...

Listen, the people you help when you start a load of towels or the dishwasher on your way out are not the Airbnb owners. They're the people hired to clean the place, who are paid poorly and irregularly. Some requests are ridiculous, yes, but some are about considering a cleaner's time. Tip well.

I agree - use an artist. Mark is one of the best!

As scientists we are trained to look for simple explanations that fit the data in front of us and make testable predictions about what will happen in the future.

Some have called it a “Phoenix planet.” The latest from Hubble:

What a great way of putting it!

They're holding up a major escalation in Iran and a crackdown on abortion until after the midterms to limit political damage. To the extent that the last two years have been a right-wing smash-and-grab operation, the next two will be worse.

#NASAWebb has provided a crash course on planet-shattering collisions, providing clues to the amount of energy in their collisions. (1/6) 🧵 🔭 🧪

It’s not everyday (but more often than most might think) that a NASA astronaut walks through our doors. The most recent: Baltimore-native Reid Wiseman, commander of NASA’s Artemis II mission! Last week, he stopped by to hear about NASA's flagship astrophysics missions. Credit: NASA/STScI

It’s Friday night. I’ve done enough this week. You’ve done enough this week. ❤️🧡💛💚🩵💙💜

What was it like to witness the launch of the #NASARoman Space Telescope? I got to share my thoughts in this STScI newsletter article: www.stsci.edu/contents/new...

The only vaccine that has ever knocked me for a loop was round two of the initial Covid shot. Totally worth it. 

Watching this, I learned about a body that operates differently than mine, so I am sharing as requested. I think many people could use a little more education in this area. 

Woo!

If you need an uplifting thought today, I just saw two hummingbirds “dancing” with each other. ❤️

I had a feeling this would happen.

This epic thread is well worth your time!

Wishing those of us in the US a restful Labor Day weekend.

Whaaaaat?

I had never heard of nor read this essay before, but it is something. 

There are endless studies showing this and also the financial and societal benefits of universal basic income and or housing-first policies but the U.S. never goes for any of it because it would require allowing the poor to receive benefits that the rich consider “undeserved”

This morning's launch of the Nancy Grace Roman Space Telescope from the Kennedy Space Center was amazing! Roman is now on a million-mile journey to Lagrange point 2, where it will soon reveal the universe’s darkest secrets: https://go.nasa.gov/4qIa69I #NASARoman 🔭 Credit: J. Barrientes/STScI.

This morning I saw a rocket launch! Go Roman Space Telescope!!

Around Baltimore, staff from the Space Telescope Science Institute are sharing their enthusiasm about the upcoming launch of the Nancy Grace Roman Space Telescope. Let us know if you see one of our staff signs out in the wild! #NASARoman 🔭

At the beach watching someone build a “sand castle” and it reminds me of the Buddhist Sand Mandala. Reminding us of the ephemeral nature of our very existence is one of the most beautiful parts of Buddhism in my opinion. 

Jennifer Lotz, director of the Space Telescope Science Institute, spoke with Maryland Public Television's Jeff Salkin this week about the upcoming launch of the Nancy Grace Roman Space Telescope. #NASARoman 🔭

You know those extra loud, extra smelly vehicles driven by men trying to hide their feelings of inadequacy? Let’s agree to call them vehicular penis pumps.

There aren’t many celebrities of this age whose death would be like a punch in the gut, much as l’ve loved them. Dolly Parton feels different. Like some balancing pure Good in this world is being lost. What a heart, what a voice, what a beautiful human. RIP queen. 🩷💜❤️ variety.com/2026/music/n...

And also, I am taking a vacation next week.

This illustration depicts a dramatic collision that occurred about 12 billion years ago between our young Milky Way and a dwarf galaxy. Hubble has provided definitive evidence of this long-ago galactic merger: https://news.stsci.edu/4z7D1YN 🔭

My latest, on how the British/global media hounded Jason Arday to death. “Given the history of white media’s key role in terror against Black people, at what point do we call such actions of journalism outlets digital terror campaigns? “ karenattiah.substack.com/p/jason-arda...

It’s Friday night. I’ve done enough this week. You’ve done enough this week.

#NASAWebb imaged the Lion Nebula in near- and mid-infrared light just in time for #WorldLionDay. The stellar core, looking like the lion’s “nose,” is responsible for sculpting the nebula’s complex gas and dust structures: https://news.stsci.edu/4x639kM

It's #InternationalCatDay, so we just have to share these Gatos Andinos again 🐈 These two were spotted down the ridge from NSF–DOE Rubin Observatory. 🔭🧪 Because they live in such remote mountain terrain, seeing them up close like this is an incredibly rare treat 🐱 📷: SOAR Day Crew

The images from this story are seared into my brain. But I did not remember that today was that date. 

What the hell IS dark energy anyway?

Whew!

This is real and it’s gonna be spectacular. MST3K old-fart reunion in actual movie theaters! Right next to the freakin Minions!!
