Bubble eyes a loose spiral galaxy
ScienceDaily (23 November, 2012) - NASA / ESA hubble space telescope spiral galaxy ESO 499 G37, a distant background galaxies are scattered with stars against a nearby want to see here.
Seen from the perspective of a galaxy, the spiral nature of bubble clearly is allowed. Unconscious, loose spiral galaxy arms around the center of the swirling bluish features that can be recognized as. The blue tinge hot, young stars located in the spiral arms emanates. Milky Way spiral arms are large amounts of gas and dust, and often in areas where new stars are constantly making.
Most feature a bright center of galaxy is elongated. bulging central core usually has the highest density of stars in the Galaxy, where usually a large group of relatively cool old stars compact, spheroidal region is packed in contains.
A common feature of many spiral galaxies running across the center of the galaxy is present. The center bars with spiral arms as a mechanism that channels gas to work, thinking, star formation is enhanced.
Recent studies suggest that ESO 499-G37 sits in the center of a small bar with a few hundred tenth year of light about the size of a typical galactic bar.However, the relationship between time and still create the bulge bars in spiral galaxies is not universal feature is not clear.
Galaxy ESO G37 499 Hydra, which is shared with Antlia Star is located in the southern border.
ESO 499 G37 ESO (B) Atlas survey ESO / Uppsala in the late seventies was observed for the first time. This is a joint European Southern Observatory (ESO) and Uppsala Observatory, La Silla Observatory, who, Chile, ESO 1 m Schmidt telescope, used in a large part of the southern sky, looking for stars, galaxies status initiated by Map was planned, clusters, and planetary nebulae.
This photo is visible to infrared survey advanced camera with the wide field channel investment was made. Field of view is about 3.4 arcminutes wide.
