Scientists have discovered the great-granddaddy of all stars. They believe that the star is almost as old as existence itself—barely younger than the big bang. The star known as HE 1523-0901, is the oldest star ever seen, with quite different attributes than most other stars.

In 1934 Bulgarian born Fritz Zwicky of the California Institute of Technology recogzined that there wasn’t nearly enough visible mass in the universe to hold galaxies together and that there must be some unknown gravitational force –what we now call dark matter (simulation left). It now appears that perhaps as much as 99% of the universe is composed of Fritz Zwicky’s “dark matter.”
In other words, we live in a universe that for the most part we can’t even see. However thanks to Hubble Space Telescope, it looks as though a breakthrough has been made in our understanding of the mystery.

These two NASA videos show the spectacular Rosette Nebula and ancient galactic fossils, globular clusters, that date back to the birth of our galaxy.
The Rosette movie (image above) begins by showing an optical image of the Rosette nebula, a turbulent star-forming region located 5,000 light-years away in the constellation Monoceros. The view then changes to show the same region as viewed by NASA's Spitzer Space Telescope.
