Via its Research Blog, Google has announced the donation of the Sky Map project to the open source community. Originally developed by Googlers during their "20% time," the stellar application was launched in 2009 to showcase the sensors in first generation Android handsets.

taking the reins on further development through "a series of student projects." Hit the source link for the official announcement and a bit of nostalgia from Google.
