My first piece of in-person reporting from Thailand! At the Thai Space Expo in October, space companies flocked to Bangkok to discuss opportunities in the region. What does the future hold? ter.li/JO

Day 12 of the 2025 Space Telescope Advent Calendar: A Barred Spiral. This galaxy, NGC 5335, is categorized as a flocculent spiral galaxy, displaying a striking bar-like structure across its center, backdropped by dozens of other more-distant galaxies. Gift link: theatln.tc/pS0boJ4g

This year, we @statnews.com have brought you the stories of who-knows-how-many scientists, federal workers, policy experts, and patients For the next part of American Science, Shattered we revisit the stories of some of those people and how the year panned out www.statnews.com/2025/12/11/a...

At last, some resolution www.bloomberg.com/news/article...

Astronomers sure do conjure up a lot of spooky images when they look out into deep space. A short Halloween thread: Let's start with the Cosmic Bat Nebula (LDN 43). 🧪🔭 apod.nasa.gov/apod/ap24102...

An important and deeply reported story from @joshdinner.bsky.social about the hollowing out of NASA, particularly its science centers, where some current employees now refer to "climate" only as "the c-word." www.space.com/space-explor...

You can't talk me out of thinking there's something just very cool about an image of an interstellar comet taken by a spacecraft orbiting Mars: 🧪 🔭 www.scientificamerican.com/article/the-...

This took me out

This day ten years ago. On 30 October 2015 the now-destroyed Arecibo radio telescope images this giant skull looming out of the dark of space.

Thrilled to share that I'm in the October issue of National Geographic, with a story about two photography buddies—one standing on Earth, the other floating 250 miles above it—and the breathtaking views they captured: www.nationalgeographic.com/photography/...

This is one of those weeks where I'm reminded that space reporting is 95% talking about going to space and 5% actually going to space

For TIME's Best Inventions of 2025 list, I wrote about the Rubin Observatory and other fascinating projects in space, climate, and green energy: time.com/collections/...

Jared Isaacman may not totally be out of the NASA game just yet www.bloomberg.com/news/article...

This month, skywatchers will have the opportunity to observe not one but two once-in-a-lifetime comets. Astronomy's Quanzhi Ye shared some tips on how to locate and view comets A6 (Lemmon) and R2 (SWAN) with @marinakoren.bsky.social for @nytimes.com ☄️ 🔭

We’ve got 2 good binocular comets this month. R2 SWAN is poised to pass 0.26 AU from the Earth on Oct 19th, while A6 Lemmon will put on its late October dusk encore performance, low to the west. Both could be Halloween sky treats if they hold up to expectations. www.universetoday.com/articles/new...

We were interviewed recently by science writer @marinakoren.bsky.social for the New York Times on the up and coming October comet parade: www.nytimes.com/2025/10/03/s...

Have a little cosmic wonder with your spooky season: My first story for @nytimes.com, about a pair of once-in-a-lifetime cosmic visitors gracing the northern skies this month www.nytimes.com/2025/10/03/s...

If you liked my media hits in The New York Times, MSNBC and CNN and want to learn more about autism, I wrote a book about #Autism, #Neurodiversity and arguing we should stop trying to cure #ActuallyAutistic people and accept them. It's on sale for $15.19. www.harpercollins.com/products/wer...

Meet Artemis II: the first mission to send humans around the moon since 1972. I’ll be covering this mission for National Geographic, so you’ll be seeing a lot from me about it, but here’s the first: www.nationalgeographic.com/science/arti...

NEW WIRED led the way in reporting on Elon Musk's efforts to dismantle the US government. My colleagues and I spoke to 100s of employees at dozens of agencies to understand what happened. This is the definitive story of DOGE as told by those who experienced it www.wired.com/story/oral-h...

Sagittarius B2 is the Milky Way galaxy’s most massive and active star forming cloud, producing half of the stars created in the galactic center region despite having only 10 percent of the area’s star-making material. (1/4) 🧵 🔭 🧪

Ever wonder what happened to that $100 million interstellar spaceship program? Me too. www.scientificamerican.com/article/the-...

An absolute banger of a story from @sarahscoles.bsky.social about Breakthrough Starshot and its dreams of interstellar travel, a decade after the big-deal project was announced, including what happened to that dazzling $100 million promise: www.scientificamerican.com/article/the-...

HiPOD: Frosty Sand Dunes of Mars A field of sand dunes occupies this frosty 5-kilometer diameter crater in the high-latitudes of the northern plains of Mars. Some dunes appear to be climbing up the crater slope along a gully-like form. uahirise.org/hipod/ESP_06... #Mars #science #NASA

TIL that there's aluminum recovered from the Twin Towers on Mars: One piece on the Spirit rover, and another on Opportunity (both spacecraft are no longer operational) www.nasa.gov/image-articl...

Scientists just shared their best look to date at what might be the most tantalizing rock on Mars: 🧪 🛰️ www.scientificamerican.com/article/is-t...

What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and ultraviolet light of nearby, massive, infant stars. What else did #NASAWebb find in Pismis 24? https://bit.ly/4mr3cmt

And as the New York Times editorialized in response to the scientific reports, this marked “the beginning of the end of Mankind’s grand romantic dreams.”

FEMA staff who signed their name to the recent Katrina Declaration were placed on administrative leave. The notice says the move is not punitive, but others call it illegal retaliation against whistleblowers. 🧪 eos.org/research-and...

Did a dive into the saga to transport a retired Space Shuttle to Houston. The story could have easily been twice as long, it's got so many wild parts www.bloomberg.com/news/feature...

"Live, laugh, launch" is pretty damn good www.space.com/space-explor...

I'm looking away from our world for a moment. I'm looking at the little dot in this image. It's a newborn planet, 5 times the mass of Jupiter, carving a path through the disk of dust around its star. This is the first time we've seen the process clearly. 🧪🔭 www.eso.org/public/image...

After a series of failures during recent test flights, SpaceX's massive Starship had a smooth ride for Tuesday's blast-off, and successfully deployed some fake satellites.

I watched way too many "5 to 9 after 9 to 5" videos and became convinced that whether you "make the most" of your free time by being super productive or just try to relax and recover from your job, the ghost of work haunts most of our leisure www.theatlantic.com/family/archi...

"Not since the Red Scare .. has American science been so beholden to political ideology." I'm late to this brilliant @rossandersen.bsky.social piece, but it's a must-read (gift link): www.theatlantic.com/science/arch...

Yes I AM blaming every still-packed box and undone chore on these quirks of Earth's rotation and no I am not open to feedback about that decision. (Come on Earth's wild ride with me!): 🧪 www.scientificamerican.com/article/why-...

Acting NASA Administrator Sean Duffy has sent his first communique to the agency's workforce

This is a lovely piece about, among other things, why obituaries matter. www.politico.com/news/magazin...

In 2022, Elon Musk ordered staff to shut off Starlink service in parts of Ukraine where troops were pushing into during a critical counteroffensive against Russia. Our story today examines this order, and Starlink's relationship with governments around the world since www.reuters.com/investigatio...

I wrote about Rubin again, this time about the telescope's capacity to find potentially dozens of interstellar objects. It's going to be wild, as one astronomer put it, "like old-fashioned astronomy: Find the thing, point telescopes at it, argue about it." www.nationalgeographic.com/science/arti...

NEW: Betelgeuse, a big red star, will eventually explode. But despite its self-destructive proclivities, the irritable giant has managed to make, and keep, a friend: a companion star that Betelgeuse will, eventually and rudely, eat up. Me @nytimes.com www.nytimes.com/2025/07/21/s...

You can tell a lot about how Trump feels about his own power and influence by the way he’s posting. In that context, I wrote about Trump's addled social media crashout over the weekend and how it's different from a few months ago when he had more juice www.theatlantic.com/technology/a...
