This animation shows in blue the Hubble Space Telescopes Observations in the same area of the Sky as ALMA observations (in red and yellow) of W2246-0526. The big blue galaxy observed by Hubble is located much clores to Earth than the studied system, hence it is not part of this study. The animation clearly shows how ALMA can observe and reveal these stream-structures where the optics telescopes can’t. Credit: T. Diaz-Santos et al; / Hubble Space Telescope / N.
