This is VERY exciting 🌟 🔭 Maybe the first find of a millisecond pulsar in the galactic center 👀

Finally out in the Astrophysical Journal. Results from the deepest radio pulsar search of the innermost 1.4 arcminutes of the Galactic Center region at 10 GHz. Work led by recent Columbia PhD Karen Perez. iopscience.iop.org/article/10.3...

Exclusive view into the heart of the ELT! 👀 This image captures the interior of our ELT, under construction in Chile's Atacama Desert. The main structure shown here will host the ELT’s five mirrors. Read more: https://www.eso.org/public/images/potw2605a/ 🔭 🧪 📷 ESO/J. C. Muñoz-Mateos

How much damage could a cosmic ray do to a human? #AskEthan Cosmic rays come in all varieties of energy and speed, with the most energetic ones outstripping even LHC protons by a factor of millions. What would happen if one hit you? bigthink.com/starts-with-... #space #astro #physics #particle

From Ryan White @astroryan.bsky.social : There are a few locations in the solar system where the push and pull of gravity mellows out and you can orbit in (relative) peace. Read all about these islands of tranquility we call Lagrange points! ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/01/29/w...

There's some great #RadioAstronomy happening in Africa. The Ghana Radio Astronomy Observatory hosts the largest (32m) steerable single dish antenna in Africa, and its right near the equator. It's been converted for science purposes from commerical purposes. arxiv.org/abs/2601.10784 🔭📡

LaTeXML can be used to create fully accessible HTML from the source files. (Similar rules came in here a few years ago.) I followed the guide linked below. It works pretty seamlessly - I batch-converted a whole lecture course and only had to fix a couple of figures. hackmd.io/@UoL-IWG/lat...

This galaxy cluster has long received the celebrity treatment from leading telescopes, and for good reason. This Webb image is filled with examples of gravitational lensing 🔍 caused by the vast gravity of MACS J1149.5+2223. Read more 👉 www.esa.int/ESA_Multimed... 🔭 🧪

Environment of crab #pulsar CM Tauri in the center of Messier 1 from 2012 to 2016. #Hubble images (ACS F550M). Programs 14329, 13772, 13751, 13109, 12748.

What’s that in the sky? Satellite light trails could corrupt images captured by space telescopes like Hubble and potentially make some data unusable. #physics #astronomy

#sciart #spaceart #blender Animation of a type of binary star system called a DQ Her star. A white dwarf is in mutual orbit with a larger red dwarf. The strong gravitational field of the dense white dwarf draws hot gas from its companion, which forms an accretion disc around the white dwarf. 1/

#PPOD: What a wintery image: a red and white sphere that, if seen from a distance, resembles a festive decoration. The ‘bauble’ in question is actually the Manicouagan crater in the Canadian province of Quebec. 🧪

Happy new year! My all sky camera imaged the sky every 15 seconds and this picture shows what happened in the sky in 2025. It shows the length of the night and day with the hourglass shape, the monthly lunar cycle with the diagonal bands, the elevation of the Sun at local noon, and lots of clouds.

I was at a playground in Central Park with my son and an older man with a toddler came in. We gave each other the customary fathers-at-a-playground nod. It was Bruce Willis.

This cosmic butterfly is IRAS 23077+6707, the largest planet-forming disc seen around a young star yet!  Hubble has revealed it to be an unusually chaotic specimen, with wisps of material flying far beyond the disc 👉 https://esahubble.org/images/opo2606/ 🔭

🎄 Are your holiday decorations ready? Euclid has a cosmic garland to add: NGC 646. The large barred spiral galaxy appears close to a smaller galaxy to the left, but they’re actually about 45 million light-years apart 👉 https://www.esa.int/ESA_Multimedia/Images/2025/12/Euclid_s_galaxy_garland 🔭

NASA has announced when the longest total solar eclipse of the century will occur—and you won’t have to wait long. Here’s what you should know.

Our XMM-Newton has observed comet 3I/ATLAS in X-ray light! When gas molecules streaming from a comet collide with the solar wind they produce X-rays, seen here as the red glow of 3I/ATLAS 👉 www.esa.int/ESA_Multimed... Blue marks empty space with little X-rays. The black line is a detector gap 🔭 🧪

Astronomer Annie Jump Cannon was born #OTD in 1863. She was a pioneer of stellar classification and co-creator of the Harvard Classification Scheme. Over her lifetime she *manually* classified around 350,000 stars. (1/n) 🧪 🔭 👩‍🔬 ⚛️ Image: Harvard University, Radcliffe Archives

Today I learned that NASA has a collection of free ebooks that can be downloaded as pdfs or ebub format. The science books even include a children’s section with fun activites and coloring books! science.nasa.gov/multimedia/s...

NASA has completed the construction of #NASARoman! Last month, technicians joined the inner and outer portions of the observatory in Maryland. After final testing, Roman will move to the launch site at the Kennedy Space Center for launch preparations in summer 2026: https://go.nasa.gov/48EqnE8 🔭 🧪

By 2040, ~40% of the images from Hubble Space Telescope, and more than 96% from new and future space telescopes like SPHEREx, ARRAKIHS, and Xuntian will be contaminated by internet satellite constellations. Read our new NASA article in Nature: nature.com/articles/s4158…

Jocelyn Bell Burnell transformed astronomy #OTD in 1967 when she made the first observation of a pulsar. She and advisor Antony Hewish initially dubbed the object LGM-1 (“Little Green Men”) for its regular signal, but soon identified it as a rotating, magnetized neutron star. (1/n) 🧪 🔭 👩‍🔬 ⚛️
