PicturavisThis is my attempt at processing James Webb Space Telescope (JWST) data of Sh 2-305. It is an emission nebula usually visible in red (H II emission), but it is displayed here in false-color infrared. Blue areas emit higher-energy photons than red regions. This area is a stellar nursery where gas and dust remnants from supernovae or collisions form new stars. The three versions show the nebula only, with galaxies only, and with everything else.
A great deal of work went into creating a clean nebula image with as few artifacts as possible. After data extraction and initial stretching with #Siril, the single monochrome filter images were combined, processed, and cropped in #GIMP. The combined image was then run through #StarNet++ to remove most of the stars. Since StarNet++ does not work well with JWST data, it leaves artifacts for every star, especially the brighter ones, whose long spikes typical of JWST overlay large parts of the image. I therefore had to remove each star artifact manually using the clone and healing tools in GIMP. This took tens of hours to complete. #GMIC additionally helped reduce banding. As such, this is an artistic interpretation by me and is not scientifically accurate. The full resolution versions can be downloaded from https://www.picturavis.com/index?/tags/1204-jwst (these JWST images are crazily detailed).
The person responsible for this JWST proposal is Mark McCaughrean of the Max-Planck-Institut für Astronomie in Heidelberg. He also shared an initial version of the uncropped processed image: https://www.flickr.com/photos/markmccaughrean/55209728128/

Scienza et MagiaAggiornata la mappa della ragnatela cosmica. Cosmos Webb disegna lo scheletro dell’universo, l'intera survey, compresi i modoelli e le pipeline è stata resa pubblica. Grazie ai dati della survey Cosmos-Web, condotta con Jwst, è stata realizzata la mappa a oggi più dettagliata della ragnatela cosmica.

La Nasa a terminé son nouveau télescope spatial : son histoire est plus folle qu’il n’y paraît
Le lancement du prochain télescope révolutionnaire de la Nasa, le Nancy-Grace-Roman, aura lieu dès septembre prochain, en avance sur le planning. Un défi très attendu pour cet engin qui ne succède pas vraiment au James-Webb, mais plutôt à Hubble.
