An image of the ASKAP radio-continuum intensity image of the Diprotodon supernova remnant at 943 MHz. The green-dashed circle indicates the previously measured extent, while the yellow dashed ellipse indicates the new boundaries of Diprotodon’s radio emission. In the top right corner, we show the scaled size of the Moon (0.5 degrees), while in the top left corner, we show the animal Diprotodon (from Filipovic et al.).

Filipović et al. present a re-discovery of G278.94+1.35 as possibly one of the largest known Galactic supernova remnants (SNRs) – that they name Diprotodon. While previously established as a Galactic […]

Welcome to the ATNF Daily Astronomy Picture (ADAP), brought to you by staff and users of the Australia Telescope National Facility (ATNF). Our aim is to present science and engineering results, research highlights from recent publications, technical updates, telescope pictures, conference summaries, etc.

Our site was inspired by the fabulous Astronomy Picture of the Day – @APOD and the ASTRON/Jive Daily Image – @dailyimage.

We welcome all ATNF users to submit an image related to our facilities (Parkes, ATCA, Mopra, ASKAP and LBA), together with a brief description and credits. Submissions can be emailed to the ADAP curator, (phil.edwards [at] csiro.au).

The ADAP was created in December 2014 by Baerbel Koribalski and Simon Johnston. Over 2500 ADAPs have now been published. Vince McIntyre, Nathan Pope, and Andrew O’Brien are acknowledged for their dedicated technical support. The ADAP is currently curated by Phil Edwards.
