I would stop, but I have to put in a good word for NASA and how it selects and funds science. I'm starting to think maybe Avi Loeb doesn't know what he's talking about?

Heard the latest news from the LIGO-Virgo-KAGRA collaboration? We detected the collision of the most massive pair of black holes so far: #GW231123 weighing in at ~137 + ~103 times the mass of the Sun!

So to celebrate, here’s a handy chart ✨

Just how chonky are these black holes? 🤔
An infographic titled "How BIG are the BLACK HOLES we find with GRAVITATIONAL WAVES?" by @astronerdika. The graphic displays a range of black hole masses detected via gravitational waves, categorized by their size in solar masses (mass of the Sun) and represented with playful cat-like black hole illustrations. The categories from left to right are: 1. "<5 times the mass of the Sun" - Labeled "smol" - Very small black hole illustration represented by a curled up black cat - Arrow pointing left: "THIS WAY TO NEUTRON STARS" - Example: "Big component of GW230529 (~3.6 times the mass of the Sun)" 2. "~10 times the mass of the Sun" - Labeled "basic" - Slightly larger black hole cat illustration - Caption: "LOTS OF BLACK HOLES" 3. "~35–45 times the mass of the Sun" - Labeled "hefty" - Bigger black hole cat illustration - Continues the idea of a populated range 4. ">60 times the mass of the Sun" - Labeled "chonky" - Large black hole cat illustration - Caption: "FORBIDDEN TERRITORY? (can these even be made from the collapse of star cores?!)" - Example: "Components of GW190521 (~85 + ~66 times the mass of the Sun)" 5. ">100 times the mass of the Sun" - Labeled "oh lawd" - Very large, curled-up black hole cat illustration - Arrow pointing right: "THIS WAY TO INTERMEDIATE MASS BLACK HOLES" - Example: "Components of GW231123 (~137 + ~103 times the mass of the Sun)" Below the categories is a stylized black curve representing the inferred population of black holes detected by LIGO-Virgo-KAGRA. It rises sharply in the "basic" range and falls off toward the "hefty" and "chonky" ranges, with a note reading: "this curve is an artistic representation of the black hole population inferred by LIGO-Virgo-KAGRA." This infographic draws from the “Chonky Cat” meme.

I don't like to speak badly of people. I have grown up thinking and being told that if you cannot say something nice about someone, you should not say anything at all. But I must break that rule in this case because I hate Hulk Hogan very much. He is a big ugly goon and I want to squash his face. -Andre the Giant

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions. All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black. A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars. A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry.

I think the budget request for NASA just went up, cutting NASA astrophysics to 34% (and NASA science to 53%) of FY2024 levels and zeroing STEM engagement. 🔭 www.nasa.gov/fy-2026-budg...

These are research grants awarded through evaluation of their merits by scientific peers, in which the investigators are carrying out important, ground-breaking work. They're being targeted because, as required by NSF guidelines, they include some investment in benefits for the broader community.

Ted Cruz released a spreadsheet of NSF grants found to be "questionable projects that promoted Diversity, Equity, and Inclusion (DEI) or advanced neo-Marxist class warfare propaganda."

There are more planetary sci grants here then I expected. Are you here?

Seyfert's Sextet - From Judy Schmidt (geckzilla.bsky.social) - https://flic.kr/p/Jva2fX
I had processed this previously, but lately I looked at it and felt that I completely messed up the color balance, leaning too far blue. I decided I also didn't like the blur that I had used to smooth out the noise. I wish all the tidal tails were easier to see, but the imaging really isn't that deep. Regardless, it's still a beautiful dataset, and I am quite fond of this compact group of galaxies. In the lower left is that typical WFPC2 missing L-shaped chunk of data. I filled it in with some noise and matched it in brightness to make it less distracting. Just know that empty space is not actually empty; it's missing data. I also took the opportunity to check if there was any Chandra data available, and there was. The combined Chandra+Hubble version is here: flic.kr/p/JvapTn Red: WFPC2 F814W Green: WFPC2 F555W Blue: WFPC2 F439W+F336W North is NOT up. It is 10.15° counter-clockwise from up.
