A resident scientist, discovered 34 ultra-cold double dwarf star systems from a review of NOIRLab’s catalog data through the citizen science program.
The 34 double-dwarf star systems are in the Sun’s neighborhood. That means, we know that a system like this turns out to be twice as much as before!

Located in the United States, NOIRLab (National Optical-Infrared Astronomy Research Laboratory) has a catalog of four billion objects in the Universe. This data set is named the DR2 Source Catalog and is used in the citizen science program “Dunia Pekarangan: Planet 9”. What you’re looking for is a pair of brown dwarfs.
The “Dunia Pekarangan: Planet 9” program involved 100,000 citizen scientists who investigated the DR2 Source Catalog data. These citizen scientists consist of amateur astronomers and astronomers. What they did was study the photos taken by the telescope to look for the movement of the brown dwarf against the background star. Even though there are sophisticated supercomputers, they still can’t beat the human eye when looking for moving objects.
What you’re looking for is a pair of brown dwarfs. Brown dwarfs are usually dubbed failed stars because these objects fail to ignite hydrogen burning at the center. As a result, this star is colder than the average star. From the characteristics in terms of mass and size, brown dwarfs are on the boundary between the giant planets and the smallest stars.
One of the citizen scientists involved in the program is amateur astronomer Frank Kiwy who is looking for paired brown dwarfs. The results of his DR2 data investigation resulted in the discovery of 2,500 ultra-cold double dwarf candidates. To be sure, of course further observations are made. As a result, 34 ultra-cold double dwarf star systems were found. Among them are ultracool brown dwarfs that pair with white dwarfs.
This discovery was undoubtedly a major success for the citizen science program. Not only that. Programs could help astronomers understand brown dwarfs. Is this brown dwarf closer to a giant planet or a very small star. In addition, astronomers can understand the evolution of star systems over time.
