The red dots observed in the Whirlpool Galaxy are not individual red supergiants but rather H-II regions. These regions consist of large clouds of ionized hydrogen gas, energized by hot young stars within them. H-II regions are significantly larger than individual stars and are commonly found in various galaxies, including the Milky Way. This distinction is crucial for understanding the structure and composition of galaxies.
PREREQUISITESAstronomy enthusiasts, astrophysicists, and students studying stellar formation and galaxy structure will benefit from this discussion.
Yes, exactly ... those types of red patches can be seen in many galaxies, including our own onephyzguy said:No. The red dots are H-II regions, which are large clouds of hydrogen gas which have been ionized by hot young stars embedded in them. They are much larger than individual stars.
