Researchers have managed to map about three million previously unknown galaxies
Australian astronomers have managed to map 83% of the sky in just ten days using a new radio telescope, the Australian Square Kilometre Array Pathfinder (ASKAP). In total, about three million previously unknown galaxies were spotted in just 300 hours as part of the Rapid ASKAP Continuum Survey program. This is a record both in terms of the number of galaxies identified and the time it took researchers to achieve this.
The radio telescope has created "a map of the Universe more detailed than ever and at record speed," collecting no less than 13.5 exabytes of raw data. Thanks to the Galaxy supercomputer at the Pawsey Supercomputing Center, it was possible to convert this data into 2D images containing no less than 70 billion pixels.
Unravelling the secrets of the universe
The Universe's Google Maps consists of 903 images combined into one to form a map of the sky and provide valuable assistance to scientists in unlocking the deepest secrets of the universe. "All of this is made possible by innovative receivers developed by CSIRO that incorporate progressive-scan power technology that sees ASKAP generate more raw data at a faster rate than all of Australia's Internet traffic," said CSIRO, Australia's national science agency's director general, Dr. Larry Marshall.
The radio telescope benefits from a "broad field of view, generated by the new receivers designed by CSIRO, which allow ASKAP to take panoramic photos of the sky in amazing detail." The astronomy tool is based on the electromagnetic spectrum emitted by most objects in the universe to detect them, but also to study them. Its technology has made it possible to map the sky faster than before, from several years to just a few weeks, paving the way for new potential scientific discoveries.
"This census of the Universe will be used by astronomers around the world to explore the unknown and study everything from star formation to how galaxies and their super-massive black holes evolve and interact," said Dr. David McConnell, lead author and astronomer at CSIRO.
