The vast world that radio astronomers are searching for one is invisible to the naked eye, and even most types of telescopes.
Now, thanks to the latest developments in radio monitoring, scientists reveal the “low -surface brightness world” completely with circular curiosity, according to a team of researchers from Australia – including a completely new category of cosmic things.
“It consists of radio sources that they have never seen before, and each has its unique physical characteristics,” Miroslav Philipovic, an astronomer at Western Sydney University, and his colleagues, writes in the University of Western, and his colleagues in Article for Conversation. “While we study the sky with telescopes that record radio signals instead of light, we end up seeing many circles.”
Allowing astronomers to exposure in this non -square field, includes the Australian square, ASKAP, which consists of 36 strong antenna, and the South Africa Radio Telescope, which includes 64 antenna. Both are constantly involved in conducting surveys in the sky of the night, but Askap in particular leads one called the evolutionary map of the universe (EMU) launched in 2022, which seeks to calculate each radio source that can be imagined in the southern sky.
In their article, filopovic His colleagues are documenting some of the most interesting things that the new generation of radio telescope has found so far. Two of them from the astral anomaly known as the wolf star. These are huge heavenly bodies, perhaps 25 times heavier 25 times from the sun, near the end of their relatively short life. At this beloved stage, Wolf-Rayets quickly threw the bloc, forming very luminous shells, in its source, our sun excels millions of times. This light is very faded at the time when it reaches our planet, and since it wanders only for a few millions, the earning They are rare.
Astronomers wrote: “In these creatures, a previous flow of materials has cleared the area surrounding the star, allowing the current explosions to expand in a similar way in all directions.” “This field of stellar waste shows itself as a circle.”
Radical photos also revealed the presence of a number of leftovers, or the field of gases and other materials that left behind after burning a huge star through its fuel, collapsing under its own attractiveness, and exploding significantly.
“Supernova residue will be distorted through its environment over time. If a side of the explosion has passed to a cloud between the stars, we will see in the form of a mastery,” Filipovic explained. “So, the almost perfect circle in a chaotic world is a special discovery.”
And here, ASKAP managed to locate a single location: the remains of the name Teleios. It is very ideal that he was unprecedented, according to astronomers. “This offers us an opportunity to conduct conclusions about the first Supernova explosion, which provides a rare view of one of the most active events in the universe,” the scientists wrote.
The most mysterious ever is the most recent (it can be displayed here, on the right) for a new category of cosmic organisms called individual radio circles (spites), which, as the name suggests, is an exclusive visible phenomenon for wavelength. Sprites are large in an unacceptable way – large enough so that they are often imprisoned entire galaxies in their centers, with some Ten times by displaying the Milky Way.
Anxiously, this is just the beginning of our exploration of the “low -surface brightness world”, according to Philopovic, because ASKAP and Meerkat are just an introduction to the mother of all telescopes: a square kilometer, which, which is completed once completed, will be the largest observatory in history.
