A surprising shortage of hot gas in spiral galaxy M77

Must mean we found a galaxy with very few politicians.

UGA astronomers discover surprising shortage of hot gas in famed spiral galaxy NGC 1068
Finding could offer clues to origins of Milky Way

Athens, Ga. – Spiral galaxies are the glitter of the universe. These systems of stars, dust, gas and plasma are held together by gravity but seem to pinwheel across the darkness of space. They have fascinated nighthawks for hundreds of years and dazzled scientists who use increasingly sophisticated tools to study them.

Now, for the first time, astronomers from the University of Georgia have discovered a startling absence of hot gas being given off by the "disk" of a spiral galaxy first cataloged more than 225 years ago. The galaxy, now called NGC 1068, is younger than the Milky Way and could thus offer insights into the formation of our own spiral galaxy.

"In many ways, NGC 1068 is a window on our past," said Robin Shelton, who led the research. "What we've found is that the process of heating gas in this galaxy is more complex that we had expected."
