Individual atoms of oxygen had been confirmed in deep space for some time, but now a team lead by Paul Goldsmith of the Jet Propulsion Laboratory (and using the Herschel Space Observatory) has detected molecular oxygen for the first time--in the Orion Nebula. The team is theorizing the new stars' heat and light release and melt water ice attached to dust grains in the nebula, setting free the oxygen.

In 2007, Sweden's Odin telescope had a "sighting" of the oxygen molecule, but a follow-up confirmation never happened.

Oxygen is the third-most abundant element in the Universe and represents 21% of the Earth's atmosphere. It can be acquired artificially through electrolysis of water.

As we set out (some of us permanently) to the Moon and the planets and dwarf planets and asteroids and ???, we will certainly attempt to acquire any and all raw materials we encounter. The third in a series of three new Science Academy sessions will take place on 26 May at HRPO. It is called "Colonizing 'Beyond'" and it is for eight- to twelve-year-olds.
