2 weeks of AR 4274 transiting the near side of☀️
Impressive growth, from 260 MSH a day after rotating into view to a peak of 1100 MSH (45% of peak size of AR 3664) on Nov11th.

Gemini North image of Arp 78, also known as NGC 772.

Interactions with its companion galaxy NGC 770 (out of frame) left NGC 772's bottom arm elongated and asymmetrical.

A large, nearly face-on spiral galaxy fills most of the frame. Appearing somewhat like an aerial view of a hurricane, the galaxy's spiral arms swirl around a bright yellow-white center. The curling arms are defined by dark brown dust lanes and are dotted with blue stars. While the arms in the upper portion of the galaxy are somewhat poorly defined, in the bottom of the galaxy, one overdeveloped spiral arm curves counter-clockwise from about 3 o'clock to about 8 o'clock. The inner edge of this arm features a line of blue dots, which are star clusters. The outer edge of this arm is traced by filamentary dust lanes. Since this arm flattens out near its end, in contrast to the rounder upper arms, the overall shape of the galaxy resembles a paisley. The black background of space can be seen in the upper left and lower right corners of the image, filled with numerous tiny background galaxies and a few foreground stars.

HiRISE 3D: Double Impact Crater!

Glacier fill in two craters now separated, but looks like the flow went north at some point, and there is a suprising lack of erosion in some areas of the rim.

3D image shows a fantastic view of a double impact crater on Mars. The floor of both craters is smooth, most likely from glacia fill. The scene is less than 5 km, or 3 miles, across. (NASA/JPL-Caltech/University of Arizona)

Animation of X4.0 flare in AR 14274 on 2025-11-14. Nice coronal wave but not as spectacular as the X5.1 event on 2024-11-11. Protons were observed in GOES >100 MeV channel but not >500 MeV channel.

The brightest point in this Hubble image of FS Tau is a binary system, consisting of two stars orbiting each other, that have cleared much of its surrounding dust and gas away.

A nebula that contains stars and protostars. To the right of center, there is a bright white point made up of two orbiting stars with a four-pronged diffraction pattern. At 2 o’clock from this star, there is another, smaller bright light, a protostar, surrounded by a dark, edge-on disk of matter, which appears as a vertical line. In the center of the image is a cavity where the clouds are thinner and background stars shine through. The stars and protostar are on the edges of this cavity and are surrounded by dark clouds that appear like thick smoke in the light. A thin, short blue jet of material extends roughly horizontally, emerging from both sides of the disk. The jet is interrupted by the cavity and then continues to the left, cutting through the center of the frame.

A cool celestial firework (a supernova!) went off in NGC 3621, - a galaxy ~22 million light-years away - in April of this year, and lots of folks from around the world turned their telescopes to catch it.

It was very bright, even through small apertures.

I tracked it for months!

Two tile image features two vertical tiles. The first on the left is a wide angle shot of a spiral galaxy. It is small and resides within a dense star field. On the right is the zoomed in version, looking closer at Galaxy. An annotated arrow points to a white star which is the supernova. Five vertical narrow tiles, each showing a zoomed in section of an astrophotograph of a spiral galaxy’s edge. There is an arrow annotated to one of the bright stars in the galaxy which is the supernova on each of these images.
