NASA - National Aeronautics and Space AdministrationPasadena, CA – A new understanding of our galaxy’s structure began in an unlikely way: on Twitter. A research effort sparked by tweets led scientists to confirm that the Milky Way’s central bulge of stars forms an “X” shape. The newly published study uses data from NASA’s Wide-field Infrared Survey Explorer (WISE) mission.

The unconventional collaboration started in May 2015 when Dustin Lang, an astronomer at the Dunlap Institute of the University of Toronto, posted galaxy maps to Twitter, using data from WISE’s two infrared surveys of the entire sky in 2010.
