We have measured the original shape and mass of the dwarf galaxy that was ripped apart to make the Orphan-Chenab Stream! The paper is out today: https://iopscience.iop.org/article/10.3847/1538-4357/ac498a Eric Mendelsohn was the lead author on this study.

Professor Heidi has made a ~14 min video explaining the topic here: https://www.youtube.com/watch?v=ma44b8-SLcA, and a longer ~24 min video with more information here: https://www.youtube.com/watch?v=eATUWTwdOgc

Thank you to all our volunteers for helping make this possible! We seriously appreciate the contributions that you all make to this project. Without you, we wouldn't have been able to locate dark matter in the Milky Way!
