| Astronomers pioneer a 'Google street view' of galaxies Posted: 23 Jul 2014 08:09 AM PDT A new instrument based on bundles of optical fibers is giving astronomers the first 'Google street view' of the cosmos -- incredibly detailed views of huge numbers of galaxies. The optical-fiber bundles can sample the light from up to 60 parts of a galaxy, for a dozen galaxies at a time. |
