A Noteworthy Nearby Spiral Galaxy in Hydra: NGC 2835 | Hubble
This NASA/European Space Agency Hubble Space Telescope picture offers a closeup of a nearby spiral galaxy. The subject is NGC 2835. It lies 35 million light-years away in the constellation Hydra (The Water Snake). Regions of this galaxy are bright in a wavelength of red light called H-alpha emission. It can be seen along NGC 2835’s spiral arms, where dozens of bright pink nebulae appear like flowers in bloom. Astronomers are interested in H-alpha light because it signals the presence of several types of nebulae that arise during stages of a star’s life. Newborn massive stars create nebulae called H II regions that are particularly brilliant sources of H-alpha light, while dying stars can leave behind supernova remnants or planetary nebulae that can also be identified by their H-alpha emission.
By using Hubble’s sensitive instruments to survey 19 nearby galaxies, researchers aim to identify more than 50,000 nebulae. These observations will help to explain how stars affect their birth neighborhoods through intense starlight and winds.
Image Description: A spiral galaxy seen face-on. Its center is a bright glowing yellow. The galaxy’s spiral arms contain sparkling blue stars, pink spots of star formation, and dark threads of dust that follow the arms.
