"Astroquizbr" is a daily poll on Twitter to test the knowledge of those who follow us and our science outreach work.
Idealized by me, the hashtag #astroquizbr is also used by other astronomers, always respecting and disseminating each other's work.
With four possible options and 24 hours to submit them, the answers are anonymous, always surprising the readers with doses of Astronomy. When the 24 hours are over, the final answer is shared, along with an explanation, images and gifs, to make everything more fun.
Astroquizbr is also available in my website (in Portuguese only), categorized by areas: universe, galaxies, Solar System, stars, exoplanets and miscellaneous. At the end of the quiz there is a brief explanation. For more information, images and videos, please visit each question individually on Twitter, available here.
