An AAP article in today's Sydney Morning Herald reports on the detection
of a five-billion-year-old hydrogen emission from galaxy B1740-517 in Ara
by six of the "ASKAP" Australian Square Kilometre Array Pathfinder telescopes.

Elaine Sadler, Professor of Astrophysics at the University of Sydney and a member of the research team, plans a large ASKAP survey aimed at detecting several hundred galaxies.
"ASKAP looks at a relatively unexplored part of the radio spectrum, 700 to 1800 megahertz," Professor Sadler said.
"This means we'll be able to detect hydrogen gas deeper in space and, thanks to ASKAP's wide field of view, also over a much larger volume than we could before.
"We'll be hunting for galaxies that are five to eight billion years old, a timespan that represents a fifth of the universe's history."
