For anybody interested: I am starting a free sun science newsletter (on Substack) titled "Sunny Sci'd Up". With the first post coming soon, the newsletter will contain monthly updates on solar flare activity, solar cycle progression, relevant mission updates, and more. (Link below)

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right. Moving from chronological feed to the algorithmic feed also increases engagement. This is one of the most concerning papers I’ve read in awhile.

Trans people are a tiny minority of the population They are very rare and very precious They add immeasurable value to culture and the lives of those around them They are treasures who must be protected at all costs.

NASA is conducting a second wet dress rehearsal for Artemis II, in which they fully load the rocket with propellant and simulate the countdown to T-30 seconds. If they want to attempt launch in March, this need to go well. www.nasa.gov/blogs/missio...

Well which is it? Are you for birthright citizenship or against?

New GREENBURST paper submitted and on arXiv! We present results of 24000 hours of commensal single pulse survey time on the GBT, yielding a new pulsar and lots of redetections of known ones. Paper led by recent @gwacwvu.bsky.social PhD graduate Joe Kania, now at Manchester. arxiv.org/abs/2601.20143

Happy 5th landing anniversary, #Perseverance & #Ingenuity 🤖🚁 This mission has inspired more of my art than any other, and it's been such an amazing pleasure and honor! From my first knitted sock design to parachute umbrellas, and handmade silver and gold jewelry. 🔭🐡🧪🎨 A thread 🧵👇

Kids are notoriously germy, so pediatricians come face to face with a slew of diverse diseases every single day--call it an occupational hazard. It turns out all that exposure makes the docs pump out some powerful antibodies, which might make good new medicines for pesky viruses 🧪💊 my story:

On this day in space, in 1930, Clyde Tombaugh discovered #Pluto at the Lowell Observatory in Arizona 🪐 It took 85 more years before we saw the #BiggestHeart in the solar system up close, thanks to #NewHorizons in 2015, which captured this image! 📸 NASA / JHUAPL / SwRI 🔭🧪

Bookmarking this video for the next time someone claims that science communication can’t be engaging unless it’s about an inherently exciting topic or made personally relevant to people’s lives

Do you love Star Wars and geology? I’ve got a podcast for you!! I had the pleasure of geeking out with @jamesjawa.bsky.social and @melissatruth.bsky.social about the geology of Star Wars!

Using our bee-tracking drone, we discovered that honey bees 🐝 have highly precise and individual routes. Now published at @currentbiology.bsky.social : doi.org/10.1016/j.cu...

See those two dots with arrows pointing to them? They're giant gas planets orbiting their star, located 307 lightyears away. These are directly imaged exoplanets.

Hey UK peeps! If you are planning on pre-ordering Invisible Rainbows, there's currently an offer on Waterstones to get it 25% off! It's my birthday on Thursday, so I'm gonna pretend that I'm being a hobbit and this is my gift to you! www.waterstones.com/book/invisib...

For me one of the most disturbing aspects of the links between Epstein and academia is that the power and incentive structures that encouraged this entanglement are all still in place. Structurally, nothing has changed.

Kick start your space career! Until 28 February, you can apply to around 100 ESA Graduate Trainee positions if you've recently graduated or are in your final Master's year. Check out all conditions here 👉 www.esa.int/About_Us/Car... #ESArecruits 🔭🧪

Read the whole thread. Then pre-order Chanda’s book. I haven’t yet gone looking to see if the professors who ultimately convinced me that higher ed wasn’t a place I wanted to be due to their behavior are in the files. But what Chanda says resonates deeply nonetheless.

As always, the most courageous in the room are young people so thank you to student journalists at Columbia for being the only outlet to cover Greene’s self-made fall from grace. www.columbiaspectator.com/news/2026/02...

Academics vying for a spot in Epstein‘s world. There are so many. I feel the need to make a thread, so I don’t keep confusing them. 1/

Let me just make a few little adjustments to that title… “How a scientist with a PhD in Geology and 25 years of experience is helping lead California’s earthquake work” Way to devalue my experience.

We have PhD positions open in my group at Macquarie for radial velocity exoplanet projects!

From Viviana Cáceres: Kim Burtnyk shares her journey into science communication, her work as technical writer and editor at LIGO Lab, and advice for aspiring communicators. ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/02/13/k...

What I really love about this documentary is how in just a few minutes it shows the impact of the discovery—not just on science, but how it has inspired and motivated individuals, and how technology is finding applications in so many areas of life 🔭🧪⚛️🎢 #GW10Years

The NRAO released some radio astronomy valentines and NGL this one is making me giggle 💘 🔭🧪

Happy Valentine's Day to #Pluto, who got dumped in 2006 but still has the biggest heart in the solar system 💔❤️ #dwarfplanet 🔭🧪

I made this animation a few years ago but wasn't able to share it back then because gifs weren't supported. Now I can! 🐡

Using AI makes science communication worse. Period. AI use necessarily reduces accuracy, transparency and authenticity. But sci comm *needs* to be accurate, transparent, and authentic. Otherwise you’re just goofing around, which will destroy your audience‘s trust in you and in other sci comm.

It snowed enough to sculpt a fat little tyrannosaurus today!

As a queer scientist making Pride pins to pay for my transition, it means a lot to see them worn at big events like this. Massive thanks to @zackpolanski.bsky.social for boosting that visibility!

@womeninhpc.org has launched a new “Messages from Women in HPC” campaign, inviting members of the community to share short messages of advice, encouragement, or inspiration that reflect the power of community support. We encourage you to take part and share your message: forms.gle/kU87fGCiyQrC...

Today’s action “is a rejection of the most basic laws of physics”, says #climate scientist Friederike Otto. I report on the EPA revoking its own ruling on the danger of greenhouse gases: www.nature.com/articles/d41... 🧪

You can't... repeal... a scientific finding. At that point it's just called lying about it.

Had a nice profile of my research written by the UO folks, just in time for #WomenInScience day today! 😊 research.uoregon.edu/news/storyte... 🔭🧪🎢

Today we celebrate the International Day of Women and Girls in Science! The women of ASP are focused on building inclusive futures for women and girls by bringing astronomy and space education to all.💫🪐🌠 #womeninSTEM #girlsinSTEM #STEMEducation #womensrights #astronomy

Today marks the 10th anniversary of the announcement of the direct detection of gravitational waves by @ligo.org. In honor of that milestone, we've put together a collection of our coverage of gravitational-wave research through the years. #LIGO #gravitationalwaves #physics #astronomy

happy international day of women and girls in science 🧪🔭👩‍🔬🦖✨🦎 How are you supporting #womeninSTEM today? some ideas below: www.unesco.org/en/days/wome...

She spent the whole morning performatively screaming at Congressmen, but this image of Bondi saying nothing and refusing to turn around will be the only real takeaway from her testimony today.

Today is the International Day of Women and Girls in Science ♀️ Change is possible and is already happening, but there is still a lot to do, here’s some data to help us understand!

For people who don't follow the FDA closely: this is insane. Like my jaw hit the floor when I saw this. The FDA is flat out refusing to even consider Moderna's application for a new flu vaccine? The federal health apparatus is fully compromised by anti-vax conspiracy. THIS IS NUTS! BAD

Happy #InternationalDayOfWomenAndGirlsInScience! We are happy to share this online symposium organised by LIGO-India highlighting contributions from female scientists to our field of gravitational-wave astronomy indico.global/e/glorious-w... 🔭☄️👩‍💻

the moon's origin story is also the trippiest screensaver you'll ever watch www.youtube.com/watch?v=kRlh...

Happy 10 years to gravitational wave astronomy!

The morning so far

I searched the Epstein files for astronomy and astronomers, and consistent with Sean Carroll's posts about why his name is listed, it seems like Epstein was trying to rope in scientists they perceived as smart, and scientists tried to get financial backing from him. 🔭 Some examples:

Tomorrow marks the 10th anniversary of the announcement of our first detection! Back in 2016, excitement was building with everyone getting into the spirit with #ChirpForLIGO (thank you @astrokatie.com!) Reminisce with this supercut www.youtube.com/watch?v=0uzi... #GW10Years ⚛️🧪🔭
