CSIRO radio telescope maps of the southern sky

CSIRO radio telescope maps three million galaxies in a Southern Sky Survey record. An Australian radio telescope has conducted an unprecedented survey of the southern sky, mapping three million galaxies, including nearly a million never before seen, in just two weeks. ASKAP, consisting of 36 satellite dishes, is a radio telescope designed for rapid surveys of large parts of the sky (Csiro radio telescope maps).

The test, an ASKAP rapid continuous survey, was a “census” of the universe that astronomers would use to explore the unknown. Millions of star-shaped points on the resulting map are distant galaxies, some of which have never been seen before Csiro radio telescope maps.

This is the first time that CSIRO’s Australian Square Kilometer Array Pathfinder (ASKAP), a radio telescope located about 370 kilometers northeast of Geraldton in Western Australia, has been thoroughly tested, and the results have been considered a game changer for astronomers (Csiro radio telescope maps).

The Rapid ASKAP Continuum Survey (RACS csiro radio telescope maps) has created a “Google Map” of the universe from 903 radio images in 300 hours. In the past, similar surveys have taken years to complete. CSIRO astronomer and lead author David McConnell said this is an important milestone for the radio telescope and the scientific community.


The fact that this was done quickly is quite significant. It’s a game changer, he said. This means that we can go back and do it again without much effort, Csiro radio telescope maps and it gives astronomers a chance to see things that have changed. Most things are the same from year to year, but some things change dramatically.

They often turn out to be quite fascinating: black hole mergers or periodic explosions of stars. The survey was designed to test the telescope system and ensure that it can meet the high-throughput processing requirements for the square kilometer array of the future (Csiro radio telescope maps).

Star census

Housed within the quiet radio Murchison Radio Astronomy Observatory (MRO), ASKAP’s wide field of view, generated by 36 satellite dishes and a CSIRO-designed receiver, allows you to take extremely detailed panoramic photos of the sky and detect dim light from afar . .It allows. outside.

Astronomers will use the data to discover how galaxies form stars and interact with each other and with supermassive black holes. (Supply: CSIRO). While in the survey, each part of the sky was observed in just 15 minutes.

The final images reveal twice the level of detail compared to previous survey results. Each of the 903 images contained between 2,000 and 4,000 objects, and the study covered 83 percent of the sky. Dr. McConnell described the final image as a “census” of the universe, which includes the remains of exploded stars, pulsars, and nearby planets.

Terrestrial radio communications

He said the data would be used by astronomers around the world to uncover the mysteries of the universe. They are already looking at images, particularly of stars in our own galaxy that may be active, he said. The Sun, our own star, periodically emits bursts of radio emissions that can interfere with our own terrestrial radio communications.

They have found dozens of bright exotic stars with enormous bursts of energy, and observing them helps us understand the physics of these types of stars. ASKAP surveyed the entire visible sky from the Murchison Radio Astronomy Observatory in the Western Australia region. (Supply: Csiro radio telescope maps).

The 13.5 exabytes of raw data generated by the telescope were processed and reconstructed using (CSIRO radio telescope maps) CSIRO’s custom ASKAPsoft software at the Pawsey Supercomputing Center in Kensington, Western Australia. Dr McConnell said looking at the images was “fascinating” for the time.

Usually you have to wait a long time to see another image of the sky, but they come out one after another, he said. It is spectacular to see all these sources with their strange shapes, mind-boggling even for an astronomer who is used to wondering how big the universe is Csiro radio telescope maps.

No signs of intelligent life

While no extraterrestrial life was detected during the survey, occasional stars with unusual radio emission activity were detected. Dr. McConnell said the team does not expect any evidence of aliens with binoculars, but nothing has been ruled out. I would be very surprised, he said.

When we see an object that changes its radio power, there is a small chance that it is not naturally occurring radiation, which may be an outlet for some form of intelligent life. I won’t rule anything out, but I have to keep it most likely.
