NASA's Hubble confirms that galaxies are the ultimate recyclers

NASA's Hubble confirms that galaxies are the ultimate recyclers | MN News Hound | Scoop.it

New observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy elements. This process allows galaxies to build successive generations of stars stretching over billions of years.

This ongoing recycling keeps some galaxies from emptying their "fuel tanks" and stretches their star-forming epoch to over 10 billion years.
