The Hubble Space Observatory in the process of creating another ultra-deep field image of a new section of the sky got a picture one of the unusual galaxies Atlas of peculiar galaxies Halton Arp. The atlas includes 338 galaxies with unique individual features, which excludes them from the usual classification. The Hubble image poses in stunning detail the galaxy ESO 415-19 with two exceptionally long streams of stars.
The center of the galaxy ESO 415-19, which is located at a distance of 450 million light years from us, looks like an ordinary spiral galaxy. However, both of its sleeves continue with streams of stars, like long, widely spread arms of stars. These currents, long ago in the history of this galaxy, were shaped by its tidal forces. In the distant past, ESO 415-19 collided with smaller galaxies or ripped apart its neighbors in the universe. Captured by the galaxy’s gravity, the stars have stretched out into long streams over billions of years, giving it a unique look.
Hubble does not specifically study ESO 415-19 type galaxies from the Arp Atlas of Peculiar Galaxies. However, these objects are scattered throughout the sky and during other observations or between changes in the orientation of the space observatory, they fall into the field of view of this instrument and scientists. Over 10,000 galaxies of various ages, sizes, shapes and colors have been captured in an ultra-deep field image in the region of the constellation Furnace (Fornax), where the galaxy ESO 415-19 fell. But such as ESO 415-19 – there is one.
