The Australian telescope displays a new atlas of the universe at record speeds Astronomy



A new powerful telescope, developed by Australian scientists, has launched three million galaxies at a record speed, revealing the deepest secrets of the universe.

Australia’s square kilometer massif “Pathfinder” (Askap) broke records by conducting its first survey of the entire southern sky, mapping about three million galaxies in 300 hours.

Scientists used a telescope at an observatory in the hinterland of Western Australia to observe 83% of the sky.

The result is a new atlas of the universe, according to the developer and operator of the telescope, the Australian scientific agency CSIRO.

The poll – A quick survey of the Ascapa continuum – was millions of star-shaped dots; most are distant galaxies, according to CSIRO. About a million of these distant galaxies have never been seen before.

CSIRO CEO Larry Marshall said the survey revealed the deepest secrets of the universe.

“Ascap applies the latest advances in science and technology to age-old questions about the mysteries of the universe and equips astronomers around the world with new advances to solve their problems,” Marshall said in a statement.

Scientists expect to find tens of millions of new galaxies in future surveys, said CSIRO lead author and astronomer David McConnell.

The telescope depicted the sky with unprecedented speed and detail. CSIRO claims that the result proves that a survey of the entire sky can be done in weeks, not years.

The tool has a particularly wide field of view, which allows it to take panoramic pictures of the sky in high detail. The quality of the telescope’s receivers meant that the team only needed to combine 903 images to form a complete map of the sky.

Other large telescopes around the world need tens of thousands of images to make an overview of the entire sky.

CSIRO’s special hardware and software then processed 13.5 exabytes (13.5 billion gigabytes) of raw data generated by the telescope.

This raw data was generated faster than all of Australia’s Internet traffic, Marshall said.

Astronomers will be able to statistically analyze large populations of galaxies just as sociologists use national census information.

Federal Minister of Science and Technology Karen Andrews said that Ascap is an example of the world’s leading opportunities for radio astronomy in Australia.

“This new survey proves that we are ready to make a huge leap in the field of radio astronomy,” she said.

The initial results were published Tuesday in the journal Publications of the Astronomical Society of Australia.

Australians can take their own virtual tour of the map on the CSIRO website.
