What it is : Arp 142 , a pair of interact galaxy
When it was take : June 20 , 2013
The birdlike galaxy NGC 2936 is being ripped apart by the smaller galaxy NGC 2937.
Where it is : 326 million light - years from Earth , in the configuration Hydra .
Why it ’s so peculiar : Showcased recentlyby theEuropean Space Agency , this sensational image of a couple of interacting galaxies creates the illusion of a birdlike shape guarding an ball .
Is it a hummingbird , a penguin , or a sneaky porpoise creeping up onto the beach ? Arp 142 is a mythic example ofpareidolia , the human disposition to see intimate object or design in unrelated objects . However , its two galaxies are very much related in that they ’re gravitationally interact with each other .

This image depict a standard spiral galaxy called NGC 2936 and a small elliptical extragalactic nebula called NGC 2937 . When two extragalactic nebula get too close to each other , their gravity get down to warp each other . Sometimes , the galaxies merge , but other time , they rip each other apart .
If you study the sprain remains of the larger turbinate galaxy , you’re able to see the leftover of its bright magnetic core as the " eye ' " of the bird — but its once - spiraling arms of whiz are now warped run of sorry and crimson in the bird ’s body .

Although the picture was create in 2013 , it ’s resurfaced lately as scientist use theHubble Space Telescopeto finish catalog so - called singular galaxies . In September , Hubble append Arp 107 as the space telescope used its Advanced Camera for Surveys to observe appendage of theAtlas of Peculiar Galaxies , all of which are interact and merging . That catalogue was ab initio bring out in 1966 by American stargazer Halton Arp ( this peculiar wandflower ’s namesake ) .
The image of Arp 142 — a compounding of seeable and infrared light — was taken by Hubble ’s Wide Field Camera 3 , which was installed in 2009 by astronauts on Space Shuttle Atlantis , according toNASA . It was the final servicing mission , and the space scope has n’t been visited since .
