‘Dancing ghosts’: a new, deeper scan of the sky throws up surprises for astronomers
The Conversation, Other, 04/08/2021, Ray Norris

[…] We are getting used to surprises as we scan the skies in the Evolutionary Map of the Universe (EMU) project, using CSIRO’s new Australian Square Kilometre Array Pathfinder ( ASKAP ), a radio telescope that probes deeper into the Universe than any other.
