Experts from the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia’s national scientific agency, have created a new atlas of the universe.

Agency experts have mapped three million galaxies in more detail and in a record time of 300 hours, compared to previous mappings that have taken years.

The report claims that agency scientists were able to create a new atlas of the universe with nearly three million galaxies in the form of images that reveal twice as much detail as previous images. The data surrounding this new discovery is publicly available and may help other scientists study “everything from star formation to how galaxies and their supermassive black hole evolve and interact,” said lead author Dr. David. McConnell.

“We hope to find tens of millions of new galaxies in future studies,” he added.

This has been made possible by the Australian Square Kilometer Array Pathfinder (Askap), which is a collection of 36 satellite dishes that work in coordination to capture panoramic views of the sky.

Spread over a 6 km (3.7 mile) area at CSIRO’s Murchison Observatory about 700 km north of Perth, Australia, this telescope combines signals from the smallest plates and then creates high-resolution images for the scientists study them. However, the entire process costs a fraction of what a large plate typically costs, CSIRO said.

For the first time, Askap conducted a survey of the entire sky and covered 83 percent of the sky. With the technology, the scientists were able to combine 903 detailed, high-resolution images. Scientists hope to find answers to the structuring and evolution of the Earth.
