A virtual tour of the ASKAP site

January 9, 2026

Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory is one of the best locations in the world to operate radio telescopes due to it radio-quietness. The observatory is currently home […]

ATCA observations of a luminous fast blue optical transient

January 8, 2026

The composite image above features X-ray and optical data of a so-called luminous fast blue optical transient (LFBOT) named AT 2024wpp. LFBOTs are a class of object involving bright flashes […]

A Hammer-Aitoff sky projection in Galactic coordinates of observations published in the DAP from the main pulsar surveys conducted with Murriyang over the last 30 years (from Toomey et al. 2025).

The Parkes observatory pulsar data archive

January 7, 2026

Data from observations of pulsars made by Murriyang, the CSIRO Parkes 64-metre radio-telescope are more accessible than ever before, largely due to their storage in long-term archives. Containing nearly 2 […]

Murriyang pulsar data published in CSIRO’s Data Access Portal, by observing semester (from Toomey et al. 2025).

The Parkes observatory pulsar data archive

January 6, 2026

Data from observations of pulsars made by Murriyang, the CSIRO Parkes 64-metre radio-telescope over the last three decades are more accessible than ever before, largely due to their storage in […]

The SNR for the pixel centred on PSR J0901−4046 for each 10 s integration an a 1-hour long ASKAP observation. Pink vertical lines indicate pulses above a 3.4σ significance (shown by the dashed red line), and grey vertical lines indicate expected pulse arrival times. Sub-second pulses from this ultra-long period pulsar are bright enough they can be detectable in a 10-second correlator integration time.

ASKAP Detection of the Ultra-Long Period Pulsar PSR J0901-4046

January 5, 2026

A radio source with a period of 75.88 s, suspected of being an ultra-long period pulsar, was discovered in 2020 with the MeerKAT radio telescope. Lenc et al. report the […]

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.
