@wang.social it looks the same zoomed all the way out as it does all the way zoomed in.

we are thermal noise.

For those who may have missed it when it first came out.

This stunning infrared image from #JWST, released 11 July 2022, shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago.

It's the Webb’s First Deep Field...

Dark velvet sky packed with countless far-off galaxies—some look like smeared amber dots, others tiny rust-colored wisps, a few pulled into long glowing ribbons and perfect Einstein rings by the huge mass of SMACS 0723 sitting in the middle. A handful of sharp foreground stars flash their classic six-pointed glitter. All this wonder squeezed into a patch so small it would hide behind a single grain of sand if you raised it to the night sky.

People don't talk enough about how impactful the evolution of tools during the Bronze Age was. Crazy stuff back in those days.

America needs to take open models more seriously. Just this summer the early lead in open model adoption of Llama & co has been overtaken by Chinese models.

With The American Truly Open Models (ATOM) Project we're looking to build support and express the urgency of this issue.

The extreme environment at the heart of our galaxy ought to make forming stars and planets difficult, but new estimates show stars (and their planets) have no problems forming there.

I'll further note about AWS S3-Tables:

They aren't quite ready for prime-time compared to the big data lake players, but the disaggregation of the database continues, and the "data table"'s time is coming.

They could be as big as the idea of S3 as a "building block", especially if price is right.

got AWS S3-Tables working today in a demo with some of our synthetic bordereaux data.

I believe "data tables" (S3-Tables, and similar) and "data models (semantic layer, cube.dev, etc) are the future of the data platform.

I'll also note that S3-Tables are a little wonky to get working right now;

Portrait of a planet: As we mark the 35th year of Hubble in orbit, the space telescope's team has released a head-turning new view of Mars.

Image details: go.nasa.gov/42HRQl5
Other spectacular new vistas from Hubble: go.nasa.gov/3GoxMNi
A full-disc view of the planet Mars observed by the Hubble Space Telescope against a black background of space. The planet's surface has a red-orange tint. White clouds obscure much of the polar regions. Other clouds and haze drift through the atmosphere. Dark patches of exposed rock, craters, plains, and volcanic mountains can be seen.

EVIDENCE FOR CARBON DIOXIDE CYCLE in ancient #Mars found by @marscuriosity.extwitter.link is well aligned with our group findings on the growth stages of #ALH84001 carbonates. Water had an important role in forming secondary minerals into the crust rocks:

The massive star-forming molecular cloud Sagittarius C, located about 200 ly from the SMBH Sagittarius A* at the heart of the Milky Way, despite its abundance of gas and dust, produces fewer stars than expected.

Image source➡️ webbtelescope.org/contents/med...

🔭 🧪 #galactic #cosmology
Images from the MeerKAT and JWST telescopes show the star-forming region Sagittarius C, about 200 light-years from Sagittarius A*, the SMBH at the center of the Milky Way. The images include orientation arrows and scale bars for context. Radio data from MeerKAT reveal large vertical filamentary structures, while Webb captures similar, smaller filaments in a cloud of blue-green hydrogen in the infrared. Colors in the radio data are assigned based on spectral index. For Webb, colors are created by shifting the infrared spectrum to visible light: shorter infrared wavelengths appear blue, longer ones appear redder.

Chryse Planitia Surfaces - From UAHiRISE (NASA) (uahirise.bsky.social) - https://flic.kr/p/2peC3MA
This image shows part of the surface of Chryse Planitia, near the mouth of several of the giant outflow channels carved by massive floods. At this location the channel is much too large to be seen within a HiRISE image, and this shows an area of level plains near the mouth. A long trough with aeolian (wind-blown) ripples runs through part of the image. This feature likely formed by contraction of the surface layer. Image cutout is less than 1 km (under 1 mi) top to bottom and the spacecraft altitude was 284 km (176 mi). North is to the right. For full observation details including images with scale bars, visit the source link. NASA/JPL-Caltech/UArizona www.uahirise.org/PSP_006268_1995

Martian Hexagon

This rock stands out in the bedrock of the canyon where Curiosity is currently roving.

An ochre toned picture of Martian rocks and sand. One rock at center stands out by its texture, size, color and shape. Shape approximates an hexagon, owing to a projection effect from the rover's particular viewpoint.

hubble’s recent images 🌌

can’t believe this telescope is almost 35 years old and still giving us these BEAUTIFUL images of our universe 🥹
A hazy ball of white light fills the image. The ball is brighter toward the center of the image, becoming more diffuse toward the edges of the image. Bands of rusty-brown dust stretch across the core. A spiral galaxy, seen tilted at a slight angle, on a dark background of space. It glows softly from its center and out to its edge. The disk is a broad swirl of dark-reddish dust webs and sparkling blue patches where stars have formed. Atop the center of the galaxy is a foreground star that appears very large and bright with four diffraction spikes emanating from it. The star is relatively close to Earth compared to the galaxy. Wisps of pinkish-grey clouds fill the scene. Patches of dark dust obscure the glow. Bright, blue-white stars shine through the cloud. An area of space filled with stars. Most of the stars are small, distant dots in a range of orange colors; closer stars shine with a bright glow and hold four thin diffraction spikes around them. These closer stars appear both bluish and reddish. Clouds from a nebula cover the left half of the scene, giving it a blue-greenish cast. More clouds also drift over the black background of space on the right side of the image.

This image shows the planetary system HR 8799. The image background is black. At the centre of the image, there is a symbol representing a star labeled HR 8799. This star blocks the light from the host star. There are four exoplanets, which look like fuzzy dots, pictured in the image surrounding the star. Furthest from the star is a fuzzy, faint blue dot, labeled b, at the 10 o’clock position. At the one o’clock position, second furthest from the star is a blueish-white fuzzy dot labeled c. Just below that is an orange dot labeled e. At the four o’clock position, still nearby the star, is another fuzzy white dot labeled d.

why are new movie trailers not shot as VR movies?

seems like you could shoot promos with dual cameras relatively easily, even if its not as big as the main trailer.
