This bubble of ionized gas and warm dust, called RCW 79, lies in the southern Milky Way, 17,200 light years from Earth in the constellation Centaurus, and probably took about one million years to form from the radiation and winds of hot young stars. The infrared eyes of NASA's Spitzer Space Telescope have found at least three generations of stars forming in this expanding envelope. The gas and dust balloon is an example of stimulated star formation. Such stars are born when the hot bubble expands into the interstellar gas and dust around it. RCW 79 has spawned at least two groups of new stars along the edge of the large bubble. Some are visible inside the small bubble in the lower left corner. Another group of baby stars appears near the opening at the top.

Quote of the Day
Formerly, when religion was strong and science weak, men mistook magic for medicine; now, when science is strong and religion weak, men mistake medicine for magic. - Thomas Szasz, M.D.
Fact of the Day
Since being launched from Earth on October 18, 1989, Galileo has traveled 2.4 billion miles in just over 6 years to reach Jupiter. That's an average speed of 44,000 miles per hour. At that speed, one could drive around the Earth at the equator (assuming there were bridges across all the oceans) in just over half an hour, or to the Moon and back in only 11 hours!Word of the Day
