Astronomers from the project Pan-STARRS has released the second catalog of data collected over four years. Its size is 1.6 petabytes and it makes the directory largest database of astronomical data ever published.
The first telescope Pan-STARRS 1 began systematic observations in may 2010 in the optical and near-infrared range of the electromagnetic spectrum. For four years the telescope had to watch 12 times the entire available area on the celestial sphere using 5 different filters, according to the website of the Institute of space research with the space telescope.
The first catalogue of astronomical data. In December 2016 was released, the primary data directory, now the Institute of space research with the space telescope, together with the astronomical Institute of Hawaii released the second catalog of data Pan-STARRS DR2, containing pictures, which were about three billion individual sources, such as stars, galaxies, and other objects.

Second catalogue of the astronomical data. The total size of the new directory is 1.6 petabytes making it the largest ever released of astronomical data base and in 30 thousand times more than the total size of all texts of Wikipedia.
Catalog available to astronomers and observers from around the world online, the data itself is stored in the Archive for space telescopes named Barbara Mikulski. The image with the Pan-STARRS DR2 allow anyone to open a previously unknown near-earth asteroid or comet, to identify the supernova, or observing the change in brightness of a variable star or a distant quasar.
What is known about Pan-STARRS?System Pan-STARRS (Panoramic Survey Telescope and Rapid Response System) will consist of four telescopes Ritchey-chrétien mirrors with a diameter of 1.8 meters each and a 1.4-gigapixel cameras located on top of the volcano Mauna Kea on Hawaii island. At the moment put into operation two telescopes (PS1 and PS2), two more are in the process of creation.
The goal of the program is the observation of aperiodic variable objects, such as supernova, gamma-ray bursts, meteorites, space debris, brown dwarfs, comets and potentially hazardous to Earth asteroids to 24.5 magnitude.
