The SKAO Appoints Construction Directors for South Africa and Australia
Press Release from SKAO
Tracy Cheetham and Antony Schinckel have between them nearly 50 years’ experience delivering telescopes and associated infrastructure.
Two respected science infrastructure experts have been appointed to lead construction activities at the telescope sites of the SKAO, respectively, located in the Karoo in South Africa and Western Australia.
Tracy Cheetham, who is currently the head of construction planning for the South African Radio Astronomy Observatory (SARAO), will be the site construction director of the SKAO’s mid-frequency telescope in South Africa.
Antony Schinckel, who is currently the SKA’s head of construction planning for Australia and leads the SKA programme at Australia’s national science agency CSIRO, will be the site construction director of the SKAO’s low-frequency telescope in Australia.
ASKAP
A mysterious circle of radio waves has been detected, the fifth odd radio circle (ORC) ever spotted, but its cause is still unclear. It could simply be the side view of a galaxy with an active black hole at its centre, although it might be the result of a supermassive black hole merger.
In 2020, Ray Norris at Western Sydney University, Australia, and his colleagues found four strange circles made from radio waves in space. No one had seen such objects before and the team had … Continue reading Subscribe now for unlimited access

Astronomers Detect Another Mysterious Ghostly Circle in Extragalactic Space
29 APRIL 2021
The discovery of a giant, ghostly circle in extragalactic space is bringing us closer to understanding what these mysterious structures actually are.
The so-called odd radio circle, named ORC J0102-2450, joins just a handful of previously discovered space blobs. Given the low sample size, the new discovery adds important statistical data that suggest these objects could somehow be related to galaxies. The paper has been accepted into
MNRAS Letters, and is available on preprint server arXiv.
Humanity has been staring up and wondering about the sky for tens of thousands of years, but even so, space retains many secrets. Odd radio circles - ORCs - were only discovered last year, in 2019 observations collected by the Australian Square Kilometre Array Pathfinder (ASKAP), one of the world s most sensitive radio telescopes.
