That ordinary smartphone in your pocket could be a powerful tool for investigating outer space. In a new study, researchers at Google and CU Boulder have transformed millions of Android phones across the globe into a fleet of nimble scientific instruments—generating one of the most detailed maps to date of the uppermost layer of Earth’s atmosphere.

The group’s findings, published Nov. 13 in the journal Nature, might help to improve the accuracy of GPS technology worldwide several-fold. The research was led by Brian Williams of Google Research and included Jade Morton, professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at CU Boulder.

“These phones can literally fit in your palm,” Morton said. “But through crowdsourcing, we can use them to change the way we understand the space environment.”
