The Galactic Center in Radio from MeerKAT

MeerKAT's radio image reveals the Milky Way's center, including Sgr A with its supermassive black hole. The vast 2-degree view details many celestial features, while JWST's inset probes star formation and magnetic fields. Optical telescopes can't see this due to dust.

🔭✨ Voici une illustration des résultats d'observations du télescope spatial James #Webb qui montre pour la première fois l'engloutissement d'une planète de la taille de Jupiter par son étoile.
L'orbite de la planète s'est lentement dégradée au fil du temps (1->2). La planète a été complètement engloutie par l'étoile et a soufflé du gaz loin des couches extérieures de l'étoile (3).

#Jupiter and Ring in #Infrared from #Webb

Jupiter's rings, discovered by Voyager 1 in 1979, are formed by meteoroid impacts on small moons like Metis, ejecting dust into orbit. The James Webb Space #Telescope's infrared image captures these rings, Jupiter's clouds, the Great Red Spot, #moon Europa, and its shadow. Some features remain a mystery.

Starry Time Podcast

You know we love 1) Neptune (love them nep-toots) & Aurora, so this new image from #JWST is *perfection*

If you too love Neptune, check out our episode on the Nereids, where we explore some of Neptune's moons: starrytimepodcast.podbean.com/

If you love aurora, check out our episode on the science & lore of Earth's aurora: starrytimepodcast.podbean.com/

From source in toot: At the left, an enhanced-color image of Neptune from NASA’s Hubble Space Telescope. At the right, that image is combined with data from NASA’s James Webb Space Telescope. The cyan splotches, which represent auroral activity, and white clouds, are data from Webb’s Near-Infrared Spectrograph (NIRSpec), overlayed on top of the full image of the planet from Hubble’s Wide Field Camera 3.

High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows extraordinary new detail and structure in Lynds 483 (L483). Two actively forming stars are responsible for the shimmering ejections of gas and dust that gleam in orange, blue, and purple in this representative color image.

Over tens of thousands of years, the central protostars have periodically ejected some of the gas and dust, spewing it out as tight, fast jets and slightly slower outflows that “trip” across space. When more recent ejections hit older ones, the material can crumple and twirl based on the densities of what is colliding. Over time, chemical reactions within these ejections and the surrounding cloud have produced a range of molecules, like carbon monoxide, methanol, and several other organic compounds. The two protostars responsible for this scene are at the center of the hourglass shape, in an opaque horizontal disk of cold gas and dust that fits within a single pixel. Much farther out, above and below the flattened disk where dust is thinner, the bright light from the stars shines through the gas and dust, forming large semi-transparent orange cones. It’s equally important to notice where the stars’ light is blocked — look for the exceptionally dark, wide V-shapes offset by 90 degrees from the orange cones. These areas may look like there is no material, but it’s actually where the surrounding dust is the densest, and little starlight penetrates it. If you look carefully at these areas, Webb’s sensitive NIRCam (Near-Infrared Camera) has picked up distant stars as muted orange pinpoints behind this dust. Where the view is free of obscuring dust, stars shine brightly in white and blue.
