Telescope maps deep area at file velocity, reveals new galaxies

MELBOURNE: A strong new telescope in outback Australia has mapped huge areas of the universe in record-breaking time, revealing 1,000,000 new galaxies and opening the way in which to new discoveries, the nation’s nationwide science company stated on Tuesday.

The A$188 million ($138 million) radio telescope, dubbed the Australian Sq. Kilometre Array Pathfinder (ASKAP), was in a position to map about three million galaxies in simply 300 hours. Comparable surveys of the sky have taken so long as 10 years.

“It’s actually a sport changer,” stated astronomer David McConnell, who led the Commonwealth Scientific and Industrial Analysis Organisation (CSIRO) examine of the southern sky on the Murchison Radioastronomy Observatory in Western Australia.

What makes this telescope distinctive is its extensive subject of view, utilizing receivers designed by CSIRO, which permit it to take panoramic photos of the sky in sharper element than earlier than.

The telescope solely wanted to mix 903 photos to map the sky, in contrast with different all-sky radio surveys that require tens of hundreds of photos.

It’s extra delicate than earlier surveys which have lined the entire sky like this, so we do see extra objects than have been seen up to now,” McConnell instructed Reuters.

Having a telescope that may survey the sky in just a few weeks or months means the method may be repeated many times in a comparatively brief area of time, permitting astronomers to systematically spot and monitor adjustments.

“Even with this primary go we’ve received proper now, in contrast with earlier photos, we’ve already discovered some uncommon objects,” McConnell stated, together with some uncommon stars that endure violent outbursts.

He stated information gathered on this survey would permit astronomers to search out out extra about star formation and the way galaxies and black holes evolve by means of statistical analyses.

The preliminary outcomes have been revealed on Tuesday within the Publications of the Astronomical Society of Australia.
