â¦the mass that distorts the faraway galactic light is found surrounding the two giant 'eye' galaxies and a 'nose' galaxy. The multiple arcs of the circular 'face' arise from gravitational lensing of four different background galaxies well behind the 'eye' galaxies.
Chandra also said that that its x-ray observations show that that the two eyes of the cat - and the smaller galaxies associated with them - are slamming into one another in a colossal collision between galaxies: Each 'eye' galaxy is the brightest member of its own group of galaxies and these two groups are racing toward one another at over 300,000 miles [nearly 500,000 km] per hour. Data from NASA's Chandra X-ray Observatory (purple) show hot gas that has been heated to millions of degrees, which is evidence that the galaxy groups are slamming into one another. Chandra's X-ray data also reveal that the left 'eye' of the Cheshire Cat group contains an actively feeding supermassive black hole at the center of the galaxy.

Thank you for the ping, Mr. Civilizations.
That is an interesting looking Cheshire Cat, but I don’t
think a tree limb could hold up even its smile after the
rest of it disappeared into the other eye.

Amazing! Best gravitational lens I’ve ever seen. I wish they gave an estimate of the mass required to make that lens. I imagine redshift is also affected by the gravitation.
