Winners of the Third IAU OAE Astrophotography Contest Announced
Published: 15th December 2023 10:00 (UTC)
From the phases of Venus to the path of the Sun over the course of a year, the IAU Office of Astronomy for Education (OAE) third astrophotography contest has showcased a wide variety of awe-inspiring astronomical phenomena. After receiving nearly 430 remarkable entries from 40 different countries and territories worldwide, a panel of international astrophotographers and astronomy educators has now selected the winners, among which are many images taken with ordinary smartphones.
Astronomy is often considered a ‘gateway to science’ and beautiful celestial images are a valuable educational tool. When shared as open resources, they can have a lasting impact on teachers and learners globally. The OAE, building on the success of its previous contests, continues to expand its collection of high-quality educational resources, all of which are available under free licences, while recognising the dedication of those who contribute to it.
This year’s contest welcomed astrophotography enthusiasts at all skill levels. Participants submitted captivating images in various categories, including phases of Venus, day arcs of the Sun and solargraphs, sunrise and sunset locations throughout the year, and images captured exclusively with smartphones and mobile devices. Time-lapse videos highlighting the rotation of the Big Dipper or the Southern Cross were also invited.
The entries were judged not only on their aesthetic and technical merits, but also on their educational value in the context of primary- and secondary-school teaching. The winners of this year’s contest will receive well-deserved cash prizes. In the category of still images with smartphones, six winners have been awarded €100 each. In each of the other categories, three winners have been awarded €750, €500, and €250 for first, second, and third place, respectively. Additional images and videos have been recognised with honourable mentions.
“Astrophotography is an extraordinary educational tool as it enriches learning with a visually engaging experience,” says Marcella Giulia Pace, one of the winners. “Through stunning images that capture the slow flow of time in space, students gain a unique visual perspective on the Universe's complexity and beauty. This dynamic and experiential approach not only makes the subject more accessible but also sparks scientific curiosity, providing educators with an effective tool to inspire a passion for cosmic studies. This method transcends mere visual revelation, opening minds, broadening horizons, and igniting interest in the vast, mysterious Universe.”
All winning entries will be featured prominently in the OAE’s collection of astronomy education resources and the IAU Image Arquive. They will be accessible under a Creative Commons Attribution (CC BY) 4.0 International License, while ensuring that the talented photographers retain copyright to their images.
The OAE is again partnering with the OAE Center Italy as a co-sponsor of the contest. Livia Giacomini, panel member and editor-in-chief of the OAE’s astroEDU platform, says: “I was really impressed to see how many different topics can be explained with a simple image, going from very distant astrophysical objects to explanations of everyday phenomena that take place on Earth, the planet we are just starting to protect. I was aware that a picture says more than a thousand words, but with this contest it is also very clear that a picture can also teach more than a thousand words.”
This year the OAE is also delighted to collaborate with its sister office, the IAU Office for Astronomy Outreach (OAO), another co-sponsor. As part of the OAO’s mission of “astronomy for everyone”, it will host an e-exhibit and gala to honour the winners and entrants who receive honourable mentions in the smartphone astrophotography category. The date of this event will be announced soon.
Kelly Blumenthal, OAO Director, says: “Astrophotography is often seen as only available to those with significant resources and experience. In May 2023 we held a series of workshops on smartphone astrophotography, demonstrating that anyone can be an astrophotographer. We are proud to co-sponsor this contest and are excited to see the creative ways these images are used in astronomy education and outreach.”
The IAU congratulates all the talented participants in and winners of the third OAE Astrophotography Contest, whose contributions to astronomy education will inspire and educate generations to come.
