WOMEN AND GIRLS IN ASTRONOMY #WomeninSTEM #WomeninAstronomy Discover an Astronomer Poster Contest 2023The Women and Girls in Astronomy project aims to recognise the role of all women in advanc- ing science and encourage everyone on and off the gender spectrum to consider careers in astronomy. As part of the Women and Girls in Astronomy project, IAU Executive Committee Working Group Women in Astronomy and the Office for Astronomy Outreach (OAO) invite youth from 12 to 18 years old to participate in the Discover an Astronomer Poster Contest for a chance to win a telescope and share their creativity with the world! Create a poster or short video (max 3 minutes) featuring an inspiring astronomer.The subject of the poster must be an astronomer who identifies as a gender minority (including women) in STEM. We hope that the submitted posters will represent a wide cross-section of the global population, including subjects with any differing ability, from any economic background, eth- nicity, or sexual orientation.
