Australian telescope maps 3 million galaxies, hoping to reveal the cosmic mystery

Australian scientists use a telescope in remote Australia to map 3 million galaxies in space in just 300 hours, hoping to reveal the mysteries of the universe.

The ASKAP radio telescope located at the Murchison Observatory in western Australia observed about 83% of the sky, mapping about 3 million galaxies in a record short time: 300 hours.

According to the Australian Science Agency (CSIRO) – the unit that develops and operates ASKAP – about 1 million of these galaxies have never been seen before.

“ASKAP is applying the latest in science and technology to answer long-standing questions about the mysteries of the universe, while helping astronomers around the world achieve a breakthrough to solve. their challenge, “said CSIRO chief executive Larry Marshall.

ASKAP glasses map the universe with unprecedented speed and detail. The CSIRO says these results demonstrate that the sky survey can be done in weeks, not years.

CSIRO astronomer David McConnell expects to find tens of millions of other galaxies in the future.

To do this, ASKAP has an exceptionally wide field of view that enables panoramic images of the sky with an extremely high level of detail. The astronomical team only needs to combine 903 images to form a full map of the sky.

This is also the difference between ASKAP and other large telescopes in the world, according to Guardian newspaper. Accordingly, conventional telescopes need to combine tens of thousands of images to produce sky images similar to ASKAP.

Thereafter, the device customized by the CSIRO processes approximately 13.5 billion gigabytes of raw data captured by ASKAP. Marshall says raw data is processed at a faster rate than all of Australia’s Internet traffic.

Astronomers can now statistic and analyze large populations of galaxies in the same way that social scientists use information from the national census.

Initial results were published December 1 in the academic journal Publications of the Astronomical Society of Australia. Residents can also visit the virtual map on the CSIRO website.
