NASA’s Swift satellite first observed a star explosion in April 2009. It turns out that this gamma-ray burst came from a star that exploded about 13 billion years ago, the furthest that astronomers have looked back at the early beginnings of our universe.

Theory wrong: Star-mass ratio isn't same in all galaxies

A theory was found to be wrong by a group of astronomers after their research shows that there isn’t a particular ratio of high-mass newborn stars to low-mass newborn stars in all types of galaxies. Instead, stars come in a random mix of masses.

An international team of astronomers has observed for the first time a star being turned into a very fast rotating neutron star, what is called a millisecond pulsar. This discovery helps to find answers to how such massive stars evolve later in their lives.

NASA reported on February 19, 2009 that its Fermi Gamma-ray Space Telescope saw the first gamma-ray burst ever seen in high resolution. But, the big news is that the GRB is the largest ever recorded, having the "greatest total energy, the fastest motions and the highest energy initial emissions ever seen."

According to Australian astronomer David Reneke, the bright Christmas Star (or, the Star of Bethlehem), which has been written about as appearing over the little manger in the town of Bethlehem some 2,000 years ago, did not occur in December but in June. Maybe Bing Crosby should be singing about a "Green Christmas," not a White one?
