The image shows the entire circular structure of the “universe” and can only be regarded as a radio signal
The vast field of detection by radio astronomers is the invisible area of the naked eye and even most telescopes.
Now, thanks to the latest advances in radio observers, scientists are uncovering the entire “low surface brightness universe”, accompanied by circular curiosity, including a team of researchers in Australia – including a completely new class of cosmic objects.
Miroslav Filipovic, an astronomer at Western Sydney University, wrote: “It consists of a radio source that has never been seen before. paper dialogue. “When we studied the sky with telescopes that record radio signals instead of light, we ended up seeing a lot of circles.”
Astronomers are allowed to delve into this unknown field, including the Australian Square Kilometer Array Pathfinder (ASKAP) composed of 36 powerful antennas and the South African Meerkat radio telescope composed of 64 antennas. Both are constantly involved in conducting surveys of the night sky, but ASKAP in particular led a launch in 2022 called “Evolution Map of the Universe” (EMU), which aims to consider every wireless power imaginable in the southern sky.
In their articles His colleagues documented some of the most interesting objects found so far by this new generation of radio telescopes. Two of them are the stellar weird wolf ray stars. These are called Kýklos and WR16, and they are huge celestial bodies that may be 25 times the sun whose relatively short life span ends. During this dying phase, wolf rays quickly emit mass, forming extremely luminous shells, at which they come, defeating our sun millions in millions. However, when we arrived at our planet, the light was very dizzy, and since they lasted only a few million years, we discovered They are rare.
“In these objects, previous materials flow out of space around the stars, allowing the current burst to expand symmetrically in all directions,” astronomers wrote. “This field of star debris manifests itself as a circle.”
Radio images also reveal many supernova residues, or spheres and other materials of gas and other materials remain after a giant star burns through its fuel, collapses under its own gravity and explodes sharply.
“Over time, supernova residues will be deformed by the environment. If the explosion side slams into the interstellar clouds, we will see the fireplace-like shape,” Filipovitch and the company explained. “So, a near-perfect circle in a messy universe is a special discovery.”
LO, look, Askap manages to find one: a remnant named Teleios. Astronomers say it is so perfect that it doesn’t look like it. “This gives us the opportunity to infer the initial supernova explosion, thus providing rare insights into one of the most dynamic events in the universe,” the scientists wrote.
The most mysterious thing is the latest example of a new cosmic object (see here), called the odd radio circle (orcs), which, as the name suggests, is a phenomenon of wavelength visible. Orcs are big – big enough that they often imprison the entire galaxy in the center, some of which are Ten times the width of the Milky Way.
This is just the beginning of our exploration of the “low surface brightness universe” because Askap and Meerkat are just preludes to all telescope mothers: a square kilometer array (once completed) will be the largest observations in history.
