30 Doradus (the Tarantula nebula) as seen by #Hubble and #JWST.
30 Dor is a star-forming region about 50 kpc (170,000 light-years) away in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It is home to some of the hottest, most massive stars we know. (1/)
Image is 7.24 arcmin across - about 110 pc or 360 light-years.

30 Doradus is the largest and brightest star-forming region in the Local Group, the galaxies nearest to our Milky Way.
It is a "Rosetta Stone" for understanding regions of intense star formation. It's close enough to study its stars and nebular structures in detail, which can help us understand star formation in more distant galaxies.
As we go to longer wavelengths of light, we can see through more of the obscuring dust, revealing the young star cluster NGC 2070. (2/)
Hubble’s view is a mosaic captured by the ACS/WFC and WFC3 instruments.
It reveals visible and near-infrared light from the young stars, star clusters, and surrounding gas and dust.
Hubble resolves individual stars, many red protostars, as well as aging red giants and supergiants, giving astronomers insights into the stars' birth and evolution. (3/)
Here is a comparison between Hubble’s visible light and near-infrared views.
The visible light image (left) reveals glowing clouds of hydrogen and dark filamentary structures of dust.
When viewed with Hubble’s limited near-infrared vision (right), many more stars and protostars can be seen behind the dusty veil. Newly formed stars are often embedded in clouds of dust, and near-infrared light can pass through these clouds. (4/)
This JWST view is a mosaic captured by the NIRCam instrument in near-infrared light. It reveals thousands of previously unseen young stars and protostars, otherwise obscured within and behind dense areas of dust and gas.
Farther from the core region of hot young stars, cooler gas takes on a rust color, showing the signatures of dust that is made out of complex hydrocarbons. This dense gas is the material that will form future stars. (5/)
@kellylepo Imagery of stars, galaxies and nebulae always remind of a late-stage snapshot of a peculiar version of Conway's game of life that has been running for eons.
Thanks for sharing and commenting on these beautiful JWST images!
