This video takes a journey through space 👨‍🚀 to a starry view of the star-forming region IC 348. It was captured by Webb amid a search for a curious kind of object: brown dwarfs. #WebbSeesFarther 📷 @esa / @ESA_Webb , @NASA & @csa_asc , JPL-Caltech, DSS2, K. Luhman, C. Alves De Oliveira, N.

🆕 Webb has revealed a panorama of star formation in one of its largest images released to the public so far. This is the nearby star-forming region IC 348. Here, cold clouds of molecular hydrogen gas collapse to form new stars 🌟 – from massive stars that burn out after only a few million years to the smallest stars weighing just 8% of the Sun’s mass. 1/3
A star-forming region. It is blanketed in thick clouds of gas and dust, millions of kilometres across, that form swirling patterns. Bright stars are scattered throughout the clouds, with the densest cluster situated in the centre of the scene. Each is crowned with six long points created by the optics of the telescope’s mirrors. In the upper right, a couple of hidden stars blast out long, glowing jets of material.

Smaller still is a class of strange objects known as brown dwarfs. Brown dwarfs form like stars, but their cores never become hot enough to fuse hydrogen into helium. This image of IC 348 was snapped in the hunt for the smallest brown dwarfs 🔬🟤 2/3

Astronomers using Webb’s #NIRCam and #NIRSpec found brown dwarfs with masses as low as just twice the mass of Jupiter – the smallest brown dwarfs yet discovered! Read more: esawebb.org/news/weic2619/ 📷 @ESA / @esa_webb , @NASA & @csa_asc , K. Luhman, C. Alves De Oliveira, M. Zamani (ESA/Webb) 3/3
A collage, with three large panels along the top and four smaller ones on the bottom. The middle panel on top shows star-forming region IC 348. Six boxes are drawn around features in the region, numbered 1–6. The other six panels are numbered and show these features enlarged. They include bright stars throughout the nebula, protostars shooting jets of gas, a distant spiral galaxy, and a gravitational lens.
