It’s always nice to have someone in your corner, or in this case, space!

Scientists combined Hubble and data to build a fuller picture of galaxy pair VV 191, which is composed of an elliptical galaxy at left and spiral at right: https://bit.ly/4esprnX

@spacetelescope definitely worth clicking through: the image holds a second discovery that’s easier to overlook. Examine the white elliptical galaxy at left. A faint red arc appears in the inset at 10 o’clock. This is a very distant galaxy whose light is bent by the gravity of the elliptical foreground galaxy – and its appearance is duplicated. The stretched red arc is warped where it reappears – as a dot – at 4 o’clock. These images of the lensed galaxy are so faint and so red that they went unrecognized in Hubble data, but are unmistakable in Webb’s near-infrared image.
