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.

You just found the Lost Galaxy! Also known as NGC 4535, this galaxy got its nickname because it looks hazy and ghostly when viewed with a smaller telescope. With Hubble, that’s not a problem. Even from 50 million light-years away, NGC 4535’s majestic spiral arms are in full focus. The bright blue seen within these spiral arms indicates the presence of a greater number of younger and hotter stars. The yellower tones of this galaxy’s central area suggest that it’s home to stars which are older and

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
