Chhetri et al. used ASKAP to make measurements of Inter-Planetary Scintillation (IPS) with 2.5 min observations around the Sun made at a solar elongation of 10 degrees. The 16 observations around the Sun (which is marked with yellow circle) are shown, with the Chhetri et al. paper based on the single observation highlighted by the red square in the plot.

A 2.6 GHz MeerKAT image in 2023 of Cir X-1 and its natal SNR, the Africa nebula. Cir X-1 and its precessing jets on parsec scales are seen as radio sources in the centre of the nebula. To the north-west and south-east asymmetric jet inflated bubbles are visible at the edge of the SNR. Image from https://arxiv.org/abs/2601.15400

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.
