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: https://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/

#Communiqué 🗞️ Un programme d’observation de très jeunes étoiles livre ses premiers résultats. Grâce au réseau de radiotélescopes ALMA au Chili, l’équipe scientifique a détecté des molécules et leurs traces là où elles étaient supposées rares, voire inexistantes. 🔭

Cette semaine, c'est la Fête de la Science !

Profitez-en pour visiter des lieux inédits et passionnants, là où la science est en train de se faire.
L'un de ceux-là est l'Institut d'Astrophysique de Paris @iap.fr , qui vous ouvre ses portes dimanche 11 octobre.

Une occasion à ne pas manquer !

Today we have published four related papers produced by the MEGATRON Project, led by Harley Katz (U. Chicago) and Martin Rey (U. Bath, UK), Corentin Cadiou (IAP Paris, France) These articles are announced in the following thread:

La matière noire est impalpable. Elle n'émet aucune lumière et interagit très peu voire pas du tout avec son environnement. Une nouvelle pré-publication scientifique aurait détecté une fameuse particule de cette insaisissable matière. En est-on réellement certains? C’est notre obscur sujet du jour 🕳️

After a long wait, we finally have our four inaugural papers of the Megatron suite of simulations published! These simulations are the first to combine gas dynamics, gravity, radiation transfer (propagation of light) ,and* non-equilibrium chemistry.

Pour la 1ère fois, des astronomes ont détecté des ondes radio provenant d'une planète extérieure au Système solaire, en l'occurrence ici l'exoplanète Beta Pictoris b.

Le signal provient d’émissions radio aurorales, semblables à celles associées aux aurores polaires sur Terre.

Inspector Smile is ready for science! 🫡 This is Smile’s first ultraviolet view showing an auroral substorm. With the ultraviolet camera now operational, Smile becomes the first spacecraft since 2008 to capture the full ring of northern lights around the north pole in ultraviolet light. 🔭 🧪 ☀️

A galactic house of mirrors 🌌🪞

Webb has captured this spectacular view of the galaxy cluster MACS J0454.1-0300.

Its gravity is warping & multiplying the images of background galaxies, which appear like they have stepped into a house of mirrors!

A massive galaxy cluster, made of many golden elliptical galaxies with the largest, brightest one in the centre. Heavily distorted orange galaxies appear all around the cluster, the largest concentrated in a large arc around the cluster's centre; these are images of very distant galaxies, created by gravitational lensing. A few galaxies are large and bluish-white in colour; bright, nearby stars are the same colour. Credit: ESA/Webb, NASA & CSA, L. Furtak, S. Fujimoto
