Australia’s Powerful new Telescope mapped vast areas of the universe in record-breaking time, revealing one million new galaxies opening the way for new discoveries, the Australian National Science agency reported this week.
Australian Square kilometer Array Pathfinder ASKAP mapped about three million galaxies in 300 hours, according to Reuters, the comparable surveys of the sky have taken over 10 years.
Astronomer David McConnel said, “it’s really a game-changer”, David led the Commonwealth Scientific and Industrial Research Organization in a study of the southern sky at Murchison Radioastronomy Observatory in Western Australia.
“If we can look at the statistics of them, where they are on the sky, and how they interact with each other, then we learn about how galaxies like our own can form and how we came to be here on this Earth,” said Douglas Bock, CSIRO’s director of astronomy and space science.
“And if we look at a galaxy that is far away, perhaps 12 billion light-years away, we are looking back in time. So, we are looking at the light from that galaxy that was emitted when it was only a few billion years after the beginning of our universe.”
What makes this telescope is its wide field of view, using receivers innovated by CSIRO, which allows capturing panoramic pictures of the sky in sharper detail, Reuters reported.
Galaxies are the building blocks of the universe, the telescope has turned radio signals in space into sharper images, that has examined the entire southern sky, the scope needed 903 images to map the sky.
It is a sensitive survey that has covered the whole sky like this, and the science community sees more objects than in the past, such a telescope that surveys the sky in weeks and months will allow astronomers to systematically spot and track new changes.
Scientists with this new analysis found new and unusual objects in the new galaxies discovered, data gathered in the survey, allows astronomers to find more about star formation and how galaxies and black holes evolved.
“Even with this first pass we’ve got right now, compared with previous images, we’ve already found some unusual objects,” McConnell said, including some unusual stars that undergo violent outbursts.
He said data gathered in this survey would allow astronomers to find out more about star formation and how galaxies and black holes evolve through statistical analyses.
The CSIRO estimates the universe could contain as many as 1 trillion galaxies.
