The NASA/ESA Hubble Space Telescope has captured the spiral galaxy NGC 2835 before, but this image incorporates additional H-alpha emission data. The regions bright in H-alpha emission can be seen blooming in pink along NGC 2835’s spiral arms! 🌸 Astronomers are interested in H-alpha light because it signals the presence of several different types of nebulae that arise during different stages of a star’s life: from newborn stars to supernova remnants.

The spiral arms of NGC 4571 are dotted with pink nebula, heated by searing ultraviolet light from the young stars at their cores ⭐ However, stars are born in very different environments – giant molecular clouds in which the temperature hovers just a few tens of degrees above absolute zero. The transformation from freezing gas cloud to fiery young star happens thanks to gravity, which causes these clouds to collapse and heat up 🌡️ until they are hot enough to spark nuclear fusion and start to sh
