Ancient Galaxies Have Very Little Dark Matter

Ancient Galaxies Have Very Little Dark Matter younger spiral Ancient Galaxies Ancient Galaxies  New observations by an international team of astronomers’ show that huge galaxies created some 10 billion years ago, during a peak in galaxy formation, were comprised of mostly baryonic or normal matter and very little of the mysterious dark matter that tends to dominate much younger galaxies and cool galaxies The astronomers led by Germany’s Max Planck Institute for Extraterrestrial Physics made their findings after measuring the rotation of six massive and distant star-forming Ancient Galaxies. younger spiral Ancient Galaxies Using the European Southern Observatory’s (ESO) Very Large

 From our vantage point in the Milky Way Galaxy, we see NGC 6946 face-on. The big beautiful spiral galaxy is located just 10 million light-years away, behind a veil of foreground dust and stars in the high and far-off constellation of Cepheus. From the core outward, the galaxy’s colors change from the yellowish light of old stars in the center to young blue star clusters and reddish star forming regions along the loose, fragmented spiral arms. NGC 6946 is also bright in infrared light and rich in gas and dust, exhibiting a high star birth and death rate. In fact, since the early 20th century at least

Tightly Wound Lenticular galaxy

Tightly Wound Lenticular galaxy Tightly wound, almost concentric, arms of dark dust encircle the bright nucleus of the otherwise nondescript galaxy, NGC 2787, in this image created by the Hubble Heritage team. Astronomer Marcella Carollo (Swiss Federal Institute of Technology, Zurich) and collaborators used Hubble’s Wide Field Planetary Camera 2 to collect the data in January 1999.
