The galaxies SDSS J115331 and LEDA 2073461 appear to have collided.
REPUBLIKA.CO.ID, GIACARTA – This week’s photo from Hubble Space Telescope shows something of an optical illusion, that is, two galaxy that seem to collide but actually overlap by accident. Located more than a billion light-years away, the pair is made up of two spiral galaxies, one facing up and the other at an angle, which overlap to form a distinctive shape.
The galaxies, named SDSS J115331 and LEDA 2073461, were captured using Hubble’s Advanced Camera for Surveys tool.
“Although they appear to collide in this image, the alignment of the two galaxies is likely random – the two don’t actually interact,” the Hubble scientists wrote.
“Although these two galaxies may only be ships passing by at night, Hubble has captured a number of other galaxies that actually interact.”
Some photos Hubble Previous examples of actually interacting galaxies include galaxies NGC 7469 and IC 5283, which are close enough to be known by their common name, Arp 298. In this pair, a larger barred spiral galaxy is slowly merging with a more companion galaxy. small.
Earlier this year, Hubble captured the merging of other galaxies into a system known as the Angel Wing, where the merging of galaxies created a wing-like shape. Last year’s Hubble images show how extreme conditions in galaxy mergers can bring galaxies into different shapes because the spiral arms can be distorted by the large gravitational forces involved in the interactions. This interaction can result in a stream of matter flowing between two interacting galaxies as they approach each other.
Finally, one of the most impressive images of Hubble’s galactic interactions is the portrait of an object called NCG 1741, in which no fewer than four dwarf galaxies are found within 75,000 light-years of each other. These four galaxies will adapt to the space occupied by the Milky Way and, eventually, the whole group is expected to eventually merge into one galaxy.
