My biggest regret about becoming a dad is that geography has changed considerably since the 1990s, thus my children will never know the pure joy of the original Where in the World is Carmen San Diego game show.

The Confused Sportsperson

For nearly two decades I have been teaching that stars come in several colors, but never green. The reason for this is partly how stars give off light, and partly how our eyes perceive light. This new study from a team at the U of Warwick shows that white dwarf stars *can*, very rarely, be green!

I hinted that there would be more images from the Juice flyby, so here is the timelapse of the full event! It's always amazing to get these views of our fragile Blue Marble from the spacecraft we send out to explore the solar system! 🔭🧪 #planetsci

In my opinion the Infinite Monkey Theorem doesn't go far enough. An infinite number of monkeys typing for an infinite length of time will produce the complete works of William Shakespeare. Then they will do it again with every possible combination of Muppets in each role. In Swedish.

My Etsy shop is open again! I make gemstone and wire jewelry and art inspired by space. Every piece is one-of-a-kind and handmade by me. I'm busily restocking the shop; and I'm happy to make custom pieces. Check it out at elakdawalla.etsy.com

Any details on the JUICE flyby of Earth coming up later this month? Where is the best place to follow along? @science.esa.int

Happy 49th anniversary to Voyager 1! At 25.6 billion km away, it will be the furthest artificial object from Earth for decades to come.

Seeing a *lot* of breathless hype about the partial #eclipse tonight. Most of it from mainstream media and using language like "the Moon will glow red tonight" I highly recommend heading outside and looking up at the Moon throughout the eclipse. Just don't blame astronomers when you're underwhelmed

20 years ago today, Pluto was reclassified to a dwarf planet. Two decades later, we have a much better understanding of the solar system but we are nowhere near a harmonious nomenclature system.

The clouds held out just long enough from Kezar Lake, Maine for today's solar eclipse Got all the way to within ten minutes of the maximum before the sky got totally covered #eclipse

A day late, but happy anniversary to the plucky Rosetta mission and its rubber ducky comet

Today everyone — EVERYONE — should take a moment and read Ray Bradbury's four-page short story from 1950.

UTINNI! #space #tianwen2 #Kamo'oalewa

Pulling a pitcher after 7 perfect innings, at 92 pitches, in a low-stakes 8-0 game is horrendous. Unforgivable. A historic disgrace. Baseball might be dead. #mlb #perfectgame #marlins

The Legacy Survey of Space and Time has begun! Congrats to everyone involved in the Rubin observatory, we can't wait to see what discoveries are in store over the next decade. #space #verarubin

Jessica Meir is a very strong candidate to head to the Moon on one of the next few Artemis missions. Tune in today to watch her and Chris Williams give the ISS's robotic arm a tune-up. You can even see what they're seeing via split-screen helmet-cams! #nasa #iss

Much of the Expedition 74 crew is getting a nice, relaxing long weekend in space ahead of a busy Monday and Tuesday. Don't forget to tune in and watch some Canadarm2 maintenance on Tuesday! Spacewalk begins about 8:30am EDT / 12:30pm UTC

A pleasant solstice to all who celebrate! I continued my tradition of yelling "go back down!" at the sun when it hit its highest point today.

Success! Phone held up to binoculars. #occultation #moon #venus #space #astrophotography

Fingers crossed for the clouds to cooperate with today's Moon-Venus occultation. Binoculars ready!

I don't know exactly how long I've been reading @philplait.bsky.social musing about the universe, but it's surely closing in on two decades Yet he can still make me feel like a vanishingly tiny speck in the cosmos! Absolutely worth subscribing for tri-weekly doses of space-related awesomeness

When you run into an old co-worker and they haven't changed one bit

Tried to find the waning crescent Moon on the playground today. No success, but I did get this really neat-looking shot with the Sun creating some cool patterns on the camera chip.

Here's your official Artemis III crew: Commander Randy Bresnik Pilot Luca Parmitano Mission Specialist Frank Rubio Mission Specialist Andre Douglas Bob Hines is serving as a backup for each role #nasa #artemisIII

Here we go! Artemis III crew announcement is live! #artemisIII #nasa

One more day until the Artemis III crew reveal! Here's my predictions: Artemis III ---------- Anne McClain Jonny Kim Andre Douglas Kayla Barron Artemis IV ---------- Randy Bresnik Bob Hines Jessica Watkins <---next boots on the moon Alex Gerst #nasa #artemisIII

Another disappointing solar storm from Boston. Too many clouds to merit a drive out to a good dark northern horizon.

An incoming El Niño should result in a slightly below-average 2026 Atlantic hurricane season, which starts today. Nevertheless, it's good to check your preparedness and emergency kit if you live in a coastal area!

I can't believe I was at a noisy indoor event and missed the Big Boston Boom of 2026

Blue Origin just lost New Glenn on the launch pad while in prep for static fire

Artemis crew announcement alert! We will learn who will be on the next mission, Artemis III, during a NASA press conference on Tuesday 6/9 at 11am ET Remember, this mission will stay in low Earth orbit and test out systems in preparation for the Artemis IV lunar landing #nasa #artemis #artemisIII

This contrail crossing an ice crystal ring looks like a gigantic "NO SUNS" sign on the sky.

Stuck the landing, lingered long enough for a shot showing how extra crispy it got, blew up, blew up again. #starship #spacex

Managed to capture Venus with my phone-binoculars combo last night. It could be wishful thinking but it certainly looks appropriately gibbous-y to me. #venus #astrophotography

Not bad for the telescope being "my phone held up to my binoculars"! #moon #astrophotography

Super duper twilight sky show trilogy, night 2! The crescent Moon has grown and jumped east, and is now splitting the difference between Venus and Jupiter. Do look up if you haven't caught it yet!

Day one of the amazing dusk triplet: the crescent Moon cozying up to Venus in the western sky.

Amazing sky alert! The next few nights, the crescent Moon will be super close to Venus and Jupiter in the western sky just after sunset. Set an alarm and go check it out!

T Coronae Borealis remained unexploded through winter and spring, and it's now back to being easy to spot nightly from here in the northeast US. My vigil continues!

NASA's Psyche mission, on its way to get our first up-close look at a metallic asteroid, just zoomed by Mars and borrowed a tiny bit of its orbital energy. Thanks Mars! Image Credit: NASA/JPL-Caltech/ASU #psyche #nasa

Trapezoid cloud. That is all.

OTD in 1961, Alan Shepard became the 1st American & 2nd human to cross a widely-accepted boundary of space during the suborbital Mercury-Redstone 3 flight. He landed ~300 miles downrange 15 minutes after liftoff. I wish I could get that kind on time on my Boston-Philly trips of the same distance.

Thousands of new Artemis II photos! Amaze amaze amaze! Check them out in this neat viewer/poll and help determine which ones will grace the header of millions of articles for the next decade. #artemisII

The pole came out pretty good. If you look closely you'll see that it's actually the skeleton of our Xmas tree.

The episode of The Simpsons where Marge reveals she used to paint portraits of Ringo Starr aired 35 years ago. The flashback within the episode takes us back to ~1968, a 23-year jump. The Simpsons episode is now 1.5x further in our past than Beatlemania was at the time of the episode.

It's a cross-quarter day! Today marks the halfway point between the vernal equinox and the northern solstice. I hope you're making good progress on your spring cleaning task list, northern hemisphere friends!

I'm so excited to see Steve in Boston this week!

I love studies linking infrasound to paranormal nonsense. You can't hear it, but it does stress you out!
