The map, which collected data of four-year observations, shows more than 800 million stars, galaxies and near-earth asteroids.

White (STScI) and Brooks Bays (UH) The Institute of Astronomy at the University of Hawaii in Manoa, together with the Institute for Space Research with the help of the Space Telescope in Baltimore, published the second catalog of data collected over the four years of the Pan-STARRS system. The catalog contains images that hit about three billion individual objects, such as stars, galaxies, near-earth asteroids and others. The total size of the catalog was 1.6 petabytes, which makes it the largest astronomical information base ever released. Data is available to astronomers and observers from around the world.

Together with the data, the researchers presented an image of the Milky Way, which is a mosaic of photos of the starry sky. In total, Pan-STARRS has cataloged over 800 million objects in this image, including stars, galaxies and objects of the Milky Way. Also, Pan-STARRS data was used to create a map of the Milky Way galactic dust by analyzing the color and brightness of the stars represented in the image.

Pan-STARRS (“system of panoramic vision and rapid response telescopes”) – a system currently being implemented of four telescopes located on top of the Mauna Kea volcano in Hawaii, with mirrors of 1.8 meters in diameter each and 1.4-gigapixel CCD -cams. At the moment, there are two telescopes (PS1 and PS2), the other two are in the process of being created.

According to Ken Chambers, director of the Pan-STARRS observatories, observations of telescopes over the past few years have already helped the astronomical community to study cosmic phenomena in the galaxy (including thanks to the firstdata catalog released in 2016).

During the search for near-Earth objects, Pan-STARRS made many discoveries – from ʻOumuamua , passing through our solar system, to single planets between stars.

We hope that people will find all the things we missed in this incredibly large and rich data directory.
