Black holes are one of the most fascinating objects in the universe, and children are often curious about them.

In this edition of the Black Hole Week, scientists from the Athena community and the AHEAD 2020 and XMM2Athena projects funded by the European Commission in the framework of Horizon2020, answer questions from children in 4 languages.

All the videos are open-access in this dedicated playlist on the ACO YouTube channel.
