This Galaxy Is Belching Gas At 2 Million Miles An Hour

Talk about a big blowout!

For the first time ever, a galaxy has been observed blasting out cold, dense gas in vast quantities and at mind-boggling speed. This "galactic molecular outflow" from Galaxy SDSS J0905+57 has been clocked at speeds of up to 2 million miles per hour and shown to extend outward for tens of thousands of light-years.

Ice that formed in the interstellar cloud that gave birth to the sun survived that process to fill our oceans.

Good news for hunters of extraterrestrial life: Water may be more widespread in planetary systems than previously thought.

If water can form in abundance in such clouds, then it may be found everywhere.
