There is no shortage of round heavenly things in our world. Planets, satellites and stars all show beautiful spherical shapes. But astronomers have recently discovered a mysterious circular gram in the depths of the Milky Way – which is certainly not from these things.
This heavenly bubble, which was discovered by astronomical physicist Miroslav Flipovic from the West Sydney University, Supernova SNR residue, dazzling dandruff and dust dust formed by shock waves from a wonderful explosion. SNRS is not uncommon, but this particular example displays many abnormal cases, including its amazing round shape. For this form, Filipović and his team SNR Teleios, the Greek word for “Perfect”.
Discover Fileipović Teleios – officially appointed G305.4-2.2 – by chance, and scanning new photos taken by Termante Array Array Array Array Array (Askap). ASKAP currently wipes the entire southern heaven. “I was looking at these pictures because they became available, searching for anything interesting, unprecedented, and encountered via Teleios,” Filipović told Space.com. “Its circular shape was completely unusual, so I investigated more.”
Using data from ASKAP and Murchison Widefield Array, Filipović and his team estimated that Teleios extends either about 46 light years old at a distance of about 7175 light years of Earth, or about 157 light years across a distance of about 25,114 light years from Earth. (Judging such vast distances in space is difficult. Its shape was measured with 95.4 % generalization, which places it between the most accurate SNRS.
While the ideal models indicate that SNRS residue should be circular, the reality often draws a more chaotic image. Filipović says: “SNR forms of” typical “” typical “vary, either from the inconsistency of the initial explosion, or the disturbance of expansion to an ideal environment, or a number of other overlapping factors. “What makes the TELEIOS very cool shape is that it does not display any of this inconsistency; it actually looks like an explosion that occurred with almost perfect primary parameters and almost no disabled during expansion.”
So, what can explain such development without hindrance? According to Philipovic, it is likely to return to the site. Teleios is located 2.2 degrees below the galaxy level, where gas between stars and dust is significantly more superior. This environment may have allowed the remains to expand with survival without great inconvenience for thousands of years.
Teleios shape is only one of the unusual characteristics of this SNR. In addition to ambiguity, it is only emitted in the lengths of the radio wave, with a hint of alpha hydrogen emissions. “Most SNRS are visible at another frequency,” says Philipovic. “The fact that we do not see that here is very confusing. The temperatures may not be high enough to produce this emission, or that Teleios is old enough because visual emissions have faded, but radio emissions still exist.”
This shortage of emissions constitutes challenges to determine the Supernova type that has produced remotely. The most likely scenario is the Ia Supernova type, which occurs in binary The systems in which a white dwarf consumes enough of its star accompanying the explosion violently. Instead, IAX Supernova Type, which is similar to the type of Supernova of the type Ia but leaves behind the “Zombie” star. But TELEIOS data that can be noted is not perfectly suitable for the model.
Since it fits with the newly discovered things in the universe, researchers have a lot to study to reveal all the secrets of Teleios. Fortunately, there is no better time to study SNRS. “These are” golden days “for radio astronomy because new tools, such as ASKAP and Meerkat, open windows for new discoveries,” says Philipovic.
A paper on the results was presented to the publications of the Astronomical Society in Australia, and it is currently available on the Preprint server Arxiv.
