Spiral galaxies represent one of the most spectacular features in our universe. spiral galaxies in the distant universe contain significant information about their origin and evolution.
Now, NASA's James Webb Space Telescope (JWST) has taken things to the next level.
Recently, JWST has discovered red spiral galaxies. The detection of these galaxies reveal by the captured unprecedented resolution infrared images.
Captured in these unprecedented-resolution infrared images, the morphology of these galaxies is revealed in great detail.
Among the several red spiral galaxies detected, the researchers focused on the two most extremely red galaxies, RS13 and RS14.
Using spectral energy distribution (SED) analysis, the researchers measured the distribution of energy over wide wavelength range for these galaxies.
The SED analysis revealed that these red spiral galaxies belong to the early universe known as the "cosmic noon" (8-10 billion years ago), which followed the Big Bang and the "cosmic dawn."
Rare, red spiral galaxies account for only 2% of the galaxies in the local universe. One of the discovered red spiral galaxies, RS14, is a "passive" (not forming stars) spiral galaxy.
The study suggests that such passive spiral galaxies could also exist in large numbers in the early universe.
Overall, the findings of this study significantly enhances our knowledge about red spiral galaxies, and the universe as a whole.
