An ASKAP 888 MHz radio continuum image from the RACS survey showing the supernova remnant G336.7+0.5 with the putative pulsar wind nebula enclosed in the black rectangle. (Ahmad et al.)

Discovery of a young pulsar in the supernova remnant G336.7+0.5

January 13, 2025

The detection of pulsars associated with supernova remnants (SNRs) and/or pulsar wind nebulae (PWNe) is crucial for unraveling their formation history, yet associations with radio pulsars are observed in only […]

Radio (top) and gamma-ray (bottom) light-curves showing time-variability of the narrow-line Seyfert 1 galaxy PMN J0948+0022. (Shao et al.)

The variability of narrow-line Seyfert 1 galaxies with the ATCA

January 10, 2025

Shao et al. present multifrequency radio data for a sample of Narrow-Line type 1 Seyfert (NLS1) galaxies, studying the long-term radio variability of five sources and comparing it to their […]

Pptical/NIR images of the three high-redshift sources discovered in RACS. The solid orange circle indicates the optical position, while the dashed red circle is the uncertainty of the RACS radio position. (Ighina et al. 2025)

Three new high-redshift galaxies discovered in RACS

January 9, 2025

The Rapid ASKAP Continnum Survey (RACS) has produced detailed images and catalogues of the radio sky, which have been widely used by the international astronomy community. Ighina et al. present […]

Three new high-redshift galaxies discovered in RACS

January 8, 2025

The Rapid ASKAP Continnum Survey (RACS) has produced detailed images and catalogues of the radio sky, which have been widely used by astronomers worldwide. Ighina et al. present a multi-wavelength […]

Column density images of three clouds in the halo of the Small Magellanic Cloud, produced by integrating the neutral hydrogen emission over the velocity range indicated in each panel. The blue arrows indicate the direction of the dynamical centre of the SMC. (Buckland-Willis et al.)

HI clouds in the SMC halo

January 7, 2025

The Galactic ASKAP (GASKAP) survey science team is undertaking a neutral hydrogen (HI) emission survey of the 21cm line to map the Magellanic Clouds and the Galactic plane with ASKAP.  […]

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.).

The Diprotodon in the sky

January 6, 2025

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.
