WALLABY uncovers the first known ultra-diffuse galaxy pair
November 6, 2025
Optically low surface brightness galaxies have been predicted to represent a significant galaxy population. They may make up 85% of the number density for galaxies with stellar masses > 107 […]

Head-tail molecular clouds falling into the Milky Way disk
November 4, 2025
Kohno et al. report the discovery of two CO (carbon monoxide) clouds which appear to be falling into the Galactic plane at more than 35 km/s. Data from the Mopra […]
Large-Scale Radio Jets in Narrow-Line Seyfert 1 Galaxies
November 3, 2025
Powerful, large-scale relativistic jets are usually associated with massive, old elliptical galaxies. This paradigm has recently been challenged by the identification of narrow-line Seyfert 1 (NLSy1) galaxies, thought to be […]
Dark Matter Day
October 31, 2025
October 31st is celebrated as Dark Matter Day (amongst other things). Dark matter, as its name suggests, cannot be seen and its presence can only be inferred from the gravitational […]

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.
