On 7/15/21, the Chandra program released to the public a new image release entitled “Abell 1775: Chandra Catches Slingshot During Collision”. Abell 1775 is a system where a smaller galaxy cluster has plowed into a larger one. Using X-rays from Chandra and data from other telescopes astronomers are piecing together details of this collision. Features in the data, including a curving tail of hot gas and a "cold front", are clues. Scientists will likely need more observations and modeling to get the full picture of Abell 1775.
