In the aftermath of a supernova, a star's incredibly hot remains are blown into the cosmos, forming what's called a supernova remnant.
Researchers at Australia's national science agency CSIRO collected data from the extremely sensitive Australian Square Kilometer Array Pathfinder radio telescope observing an SNR in order to visualize one of these stellar oddities. They then used Setonix, a brand new supercomputer, to visualize the data.
The image Setonix synthesized, published in The Conversation, is breathtaking, demonstrating the power of supercomputers.
Researchers believe the depicted SNR, designated G261.9+5.5, dates back over a million years, having been identified back in 1967. The galaxy is at least 10,000 to 15,000 light years away.
Even though it's unclear which type of SNR we're looking at, we can at least appreciate how awesome it is.
In the interstellar medium, an SNR sweeps up, compresses, and then heats drifting material. As a result of the shockwaves, interstellar magnetic fields are compressed and energetic electrons are trapped, whose emissions can be captured by radio telescopes like ASKAP.
SNR-imaging proved to be a great way to test the Setonix supercomputer's capabilities, according to the researchers.
In order to map out something as complex as an SNR in high detail, it takes a lot of data from ASKAP to process.
It took less than 24 hours for Setonix to render G261.9+5.5 when the team tasked it with the task.
That means that scientists will be able to explore the interstellar medium and beyond more closely in the future thanks to Setonix's processing of more ambitious observations made by ASKAP.
