ZTF Robotic Camera Can Scan Entire Sky with more accuracy
ZTF Robotic Camera Can Scan Entire Sky with more accuracy - When we see sky with our smart phone’s camera we recognize objects in rest. But in reality, all objects are in motion and some materialized phenomena is going on all the time. Suppose if we exchange our smaller camera with a larger one than what will happen? The phenomena or event which take place on space are exploding of stars or comets which seems fairy like heaven. But such phenomenon can be captured with the help of a very large camera which is developed recently by Zwicky Transient Facility (ZTF) at the Palomar Observatory in San Diego.
ZTF is a robotic camera placed on 48-inch (1.2 meter) Samuel Oschin Telescope possessing 576-MP camera which can capture a full 47 degrees of the north side sky in a single click. The robotic camera can capture 3750 square degrees of sky image in one hour. The sky all around the earth is nearly 40000 square degrees. The Samuel telescope is scanning skies since the world war II era. So it will take around 3 nights to capture image of entire night sky.
The ZTF System execute those images 2.5 times faster than older installed cameras. It means the researchers can take more pictures and running events compare to slower cameras. The image captured by ZTF camera possess a resolution of about 24k by 24k pixels. The captured images are so big that they are difficult to view on a single screen. Although we need about 72 computer's monitor to watch one of such large resolution image.
The image above shows ZTF’s first captured image on 1 November 2017 at Palomar Observatory. Each such ZTF picture covers a sky area of about 247 times area covered moon. The future vision declare operation of ZTF from early 2018 to the end of 2020 to witness thousands of transient events like exploding of stars, asteroids and planets.
