The space industry, as well as professional and amateur astronomers, are devastated by space explorations by the collapse of the Arecibo Observatory’s giant radio telescope, which was vital to many. Even so, Australian astronomers have reason to be excited about the discovery of two strange space phenomena with the help of the Commonwealth Scientific and Industrial Research Organization (CSIRO )’s revolutionary ASKAP (Australian Square Kilometer Array Pathfinder) telescope.
According to a report by Newshub, the images were first found in September 2019 by Anna Kapinska and Emil Lenc, researchers at Western Sydney University.
Ray Norris, professor at Western Sydney University School of Science and creator of ASKAP, wrote an article for The Conversation, saying that Kapinska’s first image was strange shapes that astronomers cannot attribute to any category of known cosmos, specifically a « ghostly circle of radio emission » that just hung around the room.

These ORCs would not be possible without the help of the ASKAP telescope that astronomers are using for the Evolutionary Map of the Universe (EMU) project.
EMU plans to « courageously examine parts of the universe where a telescope has not yet existed, » and astronomers can do all of this with the help of the ASKAP telescope, which is particularly sensitive to faint and diffuse objects like the ORCs is that they discovered earlier.
The ASKAP telescope is very powerful, as it can survey large parts of space much faster and can be reached more deeply than before by other space telescopes.
The telescope itself is made up of 36 12-meter wide antennas – all similar and currently in use – that work together to capture areas in space.
ASKAP is also connected to more than 30 antennas equipped with special phased array feeds that were originally installed in 2017 and 5 may migrate. 2 terabytes of data per second or about 15% of the current speed of normal Internet data.
In addition, the CSIRO telescope could see a massive piece of sky with a field of view of 30 square degrees.
As of now, astronomers are not sure where the ORCs they discovered with the ASKAP telescope came from, or exactly what these strange circles are, which means scientists would need to spend more time around the real story behind the radio circles to be determined.
Even so, these Australian scientists know what these ORCs are not: they are not supernova remnants or rings of radio emission seen on galaxies forming new stars, or they are radio emissions in radio galaxies or even Einstein rings based on theirs investigation.
The group of astronomers has published their work in the publications of the Astronomical Society of Australia, in which they explain the possibilities of the discoveries.
