Margaret Hamilton, trailblazer whose software powered Apollo 11 moon landing, dies at 90
MIT computer scientist led development of software for moon mission and earned Presidential Medal of Freedom Margaret Hamilton, the computer pioneer whose software powered the first moon landing, has died, the Massachusetts Institute of Technology (MIT) announced on Wednesday. She was 90. In an era before titles such as software engineer and computer scientist became mainstream, Hamilton, who died on 30 September, learned to program under the tutelage of a renowned MIT meteorologist.

Like many scientists, I’ve been mulling over the impact of LLMs on our fields. I’ve not yet seen it articulated, but I think there is a largely unspoken “invisible labor underclass” framework at play.

NEW: The contrasting colors in NGC 7129 show differences in temperatures detected by #NASAWebb. The gold cavity at the left is hottest due to the central star and other embedded stars. The clumpy, red matter is colder and represents jets from less mature protostars: news.stsci.edu/3U8T7Bz 🔭
A young star cluster filled with many stars that display the Webb Telescope’s unique eight-pronged diffraction pattern. At its center is a yellow star, which sports the largest diffraction pattern. To the left of the star, there is a region filled with yellow dust and gas that extends from the star to the left border. This yellow region extends from the bottom, covering about two-thirds of the image. The yellow region has several blue stars of different sizes embedded within. The top third, which lies outside of the yellow region, holds a few bright protostars, within dense gray gas. Those stars illuminate the gas, making it appear blue. A few red outflows from other protostars are visible above this grayish-blue region. To the right of the central star, there is a clumpy, flame-like plume of red dust and gas with protostars that emit a soft white light within. The plume is surrounded by more dense gray gas and dust. There are several background galaxies strewn throughout the image/

On point B, the NASA Exoplanet Archive typically serves ~10-20TB of data per month. In July it jumped to 70TB. In August it jumped to 600TB. So either our user base organically grew *30x* in two months (... unlikely), OR the bots have taken over already.

A large, long portion of one of the spiral arms in spiral galaxy Messier 51. Red-orange, clumpy filaments of gas and dust stretch in a chain from left to right to comprise the arm. Shining cyan bubbles light up parts of the gas clouds from within, and gaps expose bright star clusters in these bubbles as glowing white dots. The whole image is dotted with small, point-like stars. A faint blue glow around the arm illuminates the otherwise dark background.

In 2022, we saw these three versions of the Pillars of Creation from #NASAWebb. Watch this explanation of how near- and mid-infrared data changes what we see: www.youtube.com/watch?v=Cd4C9QzapDY Which is your favorite Pillars image? Tell us below! 👇
A rectangular image with three vertical panels. Each panel shows a different version of the Pillars of Creation. The left panel is labeled “Composite Image (NIRCam and MIRI)” and shows three well-defined finger-like dense clouds reaching toward the top right from a larger cloud on the bottom left. They are grey with streaks of brown, and occasional bright red spots. The background is orange toward the top left and has more purple and blue in the lower half. Stars are scattered through the panel.

The center panel, labeled “Near-Infrared Camera (NIRCam),” shows the same cloudy figure, but the dense clouds are orange with dark orange streaks. The background is several shades of blue, from navy to bright royal blue. More and brighter stars are scattered through the background than in the composite image. 

The right panel is labeled “Mid-Infrared Instrument (MIRI)” and also displays the same finger-like clouds. The dense clouds have a murky bluish gray in this image, giving it more of a darker look. The background is several shades of dark orange with very few stars.

NEWS: #NASAWebb gives us a new view of nearby, active galaxy Centaurus A. In infrared, a rich landscape of previously hidden features and stars—all shaped by a past galactic interaction—is revealed: news.stsci.edu/4xRetmd 🔭
A horizontal image of galaxy Centaurus A stretches across a black background filled with thousands of tiny purple, pink, and white points of light. The galaxy is brightest at its center, where a brilliant white and pale pink glow radiates outward. Delicate loops and wispy ribbons of pink and lavender arc above and below the center of the image in the shape of an ‘S’. A band of gray and white dust in the shape of a parallelogram cuts across the middle of the galaxy. Mottled patches and bright knots are scattered throughout the dusty band. The galaxy’s outer edges fade into soft, cloud-like plumes with feathery textures that stretch toward the left and right sides of the image. Against the surrounding darkness, a few bright foreground stars shine, while countless fainter stars create a speckled backdrop.

There's the classic US "laboratories of democracy" notion that lots of regions trying slightly different things are more likely have one to hit on a good solution, that others can copy. In practice, they don't always learn from each other, and inefficiencies of fragmentation are non-negligible.
