Area photograph of the week: Warped ‘hummingbird galaxy’ guards a cosmic egg

What it’s: Arp 142, a pair of interacting galaxies

When it was taken: June 20, 2013

The place it’s: 326 million light-years from Earth, within the constellation Hydra.

Why it is so particular: Showcased not too long ago by the European Area Company, this gorgeous picture of a few interacting galaxies creates the phantasm of a birdlike determine guarding an egg.

Is it a hummingbird, a penguin, or a sneaky porpoise creeping up onto the seaside? Arp 142 is a superb instance of pareidolia, the human tendency to see acquainted objects or patterns in unrelated objects. Nevertheless, its two galaxies are very a lot associated in that they are gravitationally interacting with one another.

This picture reveals a typical spiral galaxy referred to as NGC 2936 and a small elliptical galaxy referred to as NGC 2937. When two galaxies get too shut to one another, their gravity begins to warp one another. Generally, the galaxies merge, however different instances, they rip one another aside.

When you research the twisted stays of the bigger spiral galaxy, you possibly can see the leftovers of its vibrant core because the “eye'” of the chicken — however its once-spiraling arms of stars are actually warped streaks of blue and pink within the chicken’s physique.

Though the picture was created in 2013, it is resurfaced not too long ago as scientists use the Hubble Area Telescope to complete cataloging so-called peculiar galaxies. In September, Hubble added Arp 107 because the house telescope used its Superior Digital camera for Surveys to watch members of the Atlas of Peculiar Galaxies, all of that are interacting and merging. That catalog was initially revealed in 1966 by American astronomer Halton Arp (this peculiar galaxy’s namesake).

The picture of Arp 142 — a mixture of seen and infrared gentle — was taken by Hubble’s Broad Subject Digital camera 3, which was put in in 2009 by astronauts on Area Shuttle Atlantis, in response to NASA. It was the ultimate servicing mission, and the house telescope hasn’t been visited since.
