🔭 Acesso a Dados Reais do James Webb e Exoplanetas

Recentemente, apareceram-me algumas imagens erradamente atribuídas ao telescópio James Webb. Eram nitidamente imagens artísticas. Recorrendo ao ChatGPT percebi que as imagens poderiam ter sido geradas ( artisticamente ) recorrendo a dados reais do James Webb.
E ele disse-me como. Vou deixar isto aqui, porque, merece a minha atenção.
Atenção, ainda não estive a visitar todos os sites. É que isto de facto, é muita coisa.

📁 Dados públicos do James Webb:

1. Mikulski Archive for Space Telescopes (MAST – da NASA)

Página principal: https://mast.stsci.edu/

Pesquisa direta de observações do JWST: https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html

2. JWST Science Archive (por instrumento e data)

Interface por filtros de tempo, alvo, instrumento (NIRCam, NIRSpec, MIRI, etc.):

https://archive.stsci.edu/jwst/search

3. Tutorial da NASA para baixar e interpretar dados do JWST

https://jwst-docs.stsci.edu/

🪐 Dados sobre Exoplanetas:

1. NASA Exoplanet Archive

https://exoplanetarchive.ipac.caltech.edu/

2. Exo.MAST – Dados observacionais do Webb focados em exoplanetas

https://exo.mast.stsci.edu/

🎓 Para Visualização e Estudo:

JWST Data Visualization Tools (Python e WebApps):

GitHub oficial com ferramentas e scripts:

https://github.com/spacetelescope

SAOImage DS9 (para ver imagens FITS):
