New Horizons is now *three days away* from shutting off its two heliophysics instruments, simply because NASA has not provided the $2M in funding it had promised to the mission last year or this year. There is no science basis for shutting these off. Our earlier coverage:

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.

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.

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.

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.)
