The initial results from the Rapid ASKAP Continuum Survey
were published this week in the Publications of the Astronomical Society of Australia.
A RACS Sky Virtual Tour, highlighting a number of notable sources, is available
from the RACS webpages.
The image above shows one such source -- the Tornado nebula.
The nature of this source has been a mystery for some decades, with
suggestion ranging from a supernova remnant in our Galaxy, to the object
being a much more distant galaxy itself. It now appears likely the object
is near the centre of our Galaxy, with the nebula powered by jets
emitted by a central, and now possibly quiescent, compact object.
