    Zwicky Transient Facility sees ‘First light’

    November 15, 2017, Categories  Astronomy/Space

    ZTF took this 'first-light' image on Nov. 1, 2017, after being installed at the 48-inch Samuel Oschin Telescope at Palomar Observatory. The full-resolution version is more than 24,000 pixels by 24,000 pixels. Each ZTF image covers a sky area equal to 247 full moons. The Orion nebula is at lower right. Computers searching these images for transient, or variable, events are trained to automatically recognize and ignore non-astronomical sources, such as the vertical 'blooming' lines seen here.

    A new robotic camera with the ability to capture hundreds of thousands of stars and galaxies in a single shot has taken its first image of the sky – an event astronomers refer to as “first light...
