AUSTRALIAN TELESCOPE MAPS DEEP SPACE IN JUST 300 HOURS

A powerful new telescope in the Australian outback has mapped vast areas of the universe in record-breaking time, revealing a million new galaxies and opening the way to new discoveries, the country’s national science agency said, Sonali Paul reported for Reuters.

The radio telescope, dubbed the Australian Square Kilometer Array Pathfinder (ASKAP), was able to map about three million galaxies in just 300 hours. Comparable surveys of the sky have taken as long as 10 years. Having a telescope that can survey the sky in a few weeks or months means the process can be repeated again and again in a relatively short space of time, allowing astronomers to systematically spot and track changes.


“It’s really a game changer,” said astronomer David McConnell, who led the Commonwealth Scientific and Industrial Research Organisation (CSIRO) study of the southern sky at the Murchison Radioastronomy Observatory in Western Australia.


What makes this telescope unique is its wide field of view, using receivers designed by CSIRO, which allow it to take panoramic pictures of the sky in sharper detail than before. The telescope only needed to combine 903 images to map the sky, compared with other all-sky radio surveys that require tens of thousands of images. “It is more sensitive than previous surveys that have covered the whole sky like this, so we do see more objects than have been seen in the past,” McConnell told Reuters.
