Fellow Texans: verify that your voter registration hasn't been suspended without your knowledge. I just double-checked mine following a link in the article; it took all of 1 minute. Make sure your voice can be heard in November.

More than 1.2 million Texans are on the state’s Voter Suspense list ahead of the fall’s contentious midterm elections. Texans still have time to check if they’re registered to vote before the October 5 deadline. Here’s how.

This is the highest-resolution view of the surface of the Sun. Ever. Taken by the NSF's Daniel K. Inouye Solar Telescope, features as small as 19 km across can be resolved. The wispy things are magnetic field boundaries formed by Kelvin-Helmholtz instabilities. The island of Ireland for scale.

A swirling, complex view of yellow–orange–brown wisp-like features. The dark shape in the middle is a superposed outline of the island of Ireland to show scale.

New images of the Sun so detailed you can almost see its face! Textbook Kelvin–Helmholtz instability patterns in images with resolution of ~20 km. With quotes from @manicule.bsky.social and @hannahschunker.bsky.social www.abc.net.au/news/science... ☄️ ⚛️ 🔭 🧪

We've never seen the Sun in this much detail before

The highest-resolution imagery of the Sun's surface ever taken reveals dizzying currents, and clues about our star's magnetic fields.

White House proposes new rules giving political appointees final approval of research grants These proposed Office of Management and Budget regulations would render the federal research grant review process opaque www.scientificamerican.com/article/whit...

BREAKING: The Department of Education has ended its directive that attempted to restrict diversity, equity, and inclusion efforts in schools nationwide. This is a victory for academic freedom and education equity.

JWST image of Arp 298, also known as NGC 7469 and IC 5283. This image is dominated by NGC 7469, a face-on spiral galaxy. Its companion galaxy IC 5283 is partly visible in the lower left corner. Credit: ESA, NASA, CSA, L. Armus, A. S. Evans Source

This image shows a spiral galaxy that is dominated by a bright central region. The galaxy has blue-purple hues with orange-red regions filled with stars. Also visible are large diffraction spikes, which appears as an 8-pointed star pattern (6 big and two smaller points) over the central region of the galaxy. In the bottom left corner of the image is a second galaxy, cut off by the frame. In the portion you can see, a haze of yellow stars is crossed by darker dust lanes. Lots of stars and galaxies fill the background scene.

After being held in two of them as a boy, I fought for decades urging America to never again build concentration camps and put human beings in them. It breaks my heart to watch this happen twice now in my own lifetime.

Screenshot of an X.com post by The Associated Press (@AP) stating that dozens of immigrant families protested for better treatment behind fences at a Texas detention facility, where a 5-year-old Ecuadorian boy and his father were sent after being detained in Minnesota. Below is a video thumbnail showing a crowd gathered outdoors along a fenced walkway; many people wear bright blue or red outerwear, and some hold signs.

3/3 Time to update the Gas Giant Portrait I created, now including the new versions of Saturn and Uranus I recently processed. Full size & more info: flic.kr/p/2oUkYSY 🔭🧪 Credit: NASA/ESA/CSA/STScI/AndreaLuck Jupiter is next on the list to be updated :)

The image is divided into four sections, each showing one of the gas giants against a black background. Top left: Jupiter. It appears as a large, round sphere with horizontal bands in shades of brown, tan, and white. A bright white oval storm sits on the lower right side. A faint ring is visible alongside Europa, one of its satellites, which appears very bright with a star-shaped artifact. Top right: Saturn. It has a pale beige surface with soft horizontal shading. Surrounding it is a wide, bright ring system tilted diagonally. The rings look thin and sharply defined, with multiple subtle bands of light and dark. Bottom left: Uranus. It appears as a smooth blue-green sphere with some whitish circular clouds around the pole that is facing the observer. Surrounding it is a bright circular ring system made up of thin white lines. The rings form a bright, symmetrical halo around the planet. Bottom right: Neptune. It is a blue sphere with slightly brighter and darker circular features on its atmosphere. It also has a thin ring system, dimmer and less defined than Uranus’s in this image, appearing as a faint double oval around the planet. Each planet has its name printed below it in white capital letters.

The raw data look like messy interferograms that are hard to understand by eye - and we enhance these data to restore beautiful images of the environment of the black hole in NGC 1068, Jupiter's moon Io, and a dusty binary system WR 137.

3x3 multipanel figure showing the AMI imaging results. Top to bottom: raw data, calibrator, and restored images, for the active galaxy NGC 1068, Jupiter's moon Io, and the colliding-wind binary WR 137.

She basically invented astrophysics. She proved the laws of chemistry, quantum mechanics, and statistical mechanics, not just gravity, applied universally. She determined the composition of the sun and primacy of hydrogen in the universe. She advised the PhDs of Frank Drake and Frank Kameny.

Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪 Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students. I wrote this little profile to mark the 100th anniversary of her thesis:

My first NASA position, as a contractor in the Kepler Science Office, was on a H-1b visa. NASA ended up giving me a medal and now I’m the Chief Scientist of NASA Exoplanet Science Institute and an American citizen to boot. Seems like a net win for the US, no? But now this:

Trump announces $1m ‘golden visa’ and raises fees for H-1B visas to $100,000 – US politics live

US president signs executive orders making it more expensive to get special skills visa while expediting process for those who can pay large sums

New protoplanet(s?) alert! I'm happy to share this LBTI image of WISPIT 2 from our team's paper led by Laird Close. Planet b was discovered at Hα with MagAO-X following the SPHERE disk discovery (R. van Capelleveen +), and CC1 might be a candidate 2nd (enshrouded?) protoplanet #exoplanets ☄️🔭🧪

Annotated false-color image of the WISPIT 2 system as seen in infrared light by the Large Binocular Telescope Interferometer (LBTI). The host star has been subtracted from the center of the image, with the inner lambda/D radius masked. Two bright circumstellar point sources are seen: CC1 - a superjovian protoplanet candidate(?) in the inner disk cavity, and b - a superjovian protoplanet in a disk gap further out. Three protoplanetary disk rings are also visible despite self subtraction from the KLIP-ADI algorithm (Rings 1, 2, and 3 in the companion paper by R. van Capelleveen et al.)
