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.

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

Young Stars and Dusty Nebulae in Taurus | NASA

Explanation: Young Stars and Dusty Nebulae in Taurus. Young Stars and Dusty Nebulae in Taurus This complex of dusty nebulae lingers along the edge of the Taurus molecular cloud, a mere 450 light-years distant. Stars are forming on the cosmic scene. Composed of almost 40 hours of image data, the 2 degree wide telescopic field of view includes some youthful T-Tauri class stars embedded in the remnants of their natal clouds at the right. Millions of years old and still going through stellar adolescence, the stars are variable in brightness and in the late phases of their gravitational collapse. Their
