Hubble captures a Long-Armed Galaxy

The Hubble mission support team has published a new image taken by the space telescope. It captures the spiral galaxy ESO 415-19.

ESO 415-19 is located at a distance of 450 million light-years from Earth in the direction of the constellation Fornax. At first glance, it resembles a typical galaxy. But if you look closely at the Hubble image, you can see its distinctive feature — long streams emanating from it, which look like spiral arms. These streams are tidal tails. They consist of stars and gas that are torn out of ESO 415-19 during its gravitational interaction with one of its galactic neighbors.

In the upper right corner of the Hubble photo, you can see a smaller orange elliptical galaxy. Most of the objects in the background are also galaxies that are even further away from Earth than ESO 415-19.

The ESO 415-19 image was taken as part of a campaign aimed at capturing remarkable galaxies. They are held during short breaks when engineers deploy Hubble to aim it at another object.
