An Improved Theory for Galaxy Rotation

May 29th, 2008 | By CentroN | Category: Astronomy


Galaxy Spiral Arm Stability and Dynamics
Simple Newtonian gravitation is sufficient to explain the entire behavior of Galaxy Spiral Arms. The well-known Keplerian effect certainly dominates, but a Spiral Arm also has internal mutual gravitation, which has surprisingly strong effects!
The stability of galaxy spiral arms has long troubled the Astrophysics community. It has been assumed that [...]

Just After Christmas - 8P/Tuttle - a second bright comet in the sky

Nov 23rd, 2007 | By CentroN | Category: Astronomy

After Comet 17P/Holmes shocked astronomers on Oct. 24, 2007, with a spectacular eruption, a second naked-eye comet, 8P/Tuttle may become visible on January 2nd just after the 2008 New Year celebrations. Given that the naked-eye comets are unusual enough, I’d encourage everyone to go out and look. The comet has an orbital period of 13.6 [...]
