Pan-STARRS astronomers published a second set of data collected over four years of work. Its size is 1.6 petabytes and makes this catalog the largest database of astronomical data ever published.
The first telescope of the Pan-STARRS 1 system began systematic observation in May 2010 in the electromagnetic and near-infrared spectrums. Depending on the site, the telescope was able to observe 12 times the total area available in the celestial field using 5 different light filters.

The first catalog of astronomical data. In December 2016, the original data catalog was published, but the Space Telescope Institute, in collaboration with the Astronomical Institute of Hawaii, published the second Pan-STARRS DR2 data repository containing images of about three billion individual sources such as stars, galaxies and other objects.

Second catalog of astronomical data. The total size of the new catalog is 1.6 petabytes, making it the largest astronomical database ever published and 30,000 times the total size of all texts on Wikipedia.
The catalog is available online for astronomers and observers around the world. The data itself is stored in the archives of the Barbary Mikulskaya Space Telescope. Pan-STARRS DR2 images allow anyone to open an asteroid or previously unknown comet, detect a supernova flash, or follow the brightness of a distant star or quasar.
What do we know about Pan-STARRS? Automated Pan-RAS (Panoramic Observation Telescope and Rapid Reaction System) will consist of four Ricci-Chrétien telescopes with 1.8 meter diameter mirrors and 1.4 cameras gigapixel located at the top of the Mauna. Kea on the island of Hawaii. By the time two telescopes (PS1 and PS2) have been commissioned, two more are being created.
The purpose of the program is to observe non-periodically changing objects, such as supernova explosions, gamma-ray bursts, meteorites, space debris, brown dwarfs, comets and potentially asteroids. dangerous for the Earth of a maximum magnitude of 24.5.
