I’m curious about the rows of galaxies… interacting galaxies in the southern sky imaged by the Hubble Space Telescope | sorae universe portal website

This is the interacting galaxy Arp-Madore 2105-332 (AM 2105-332), which is about 200 million light-years away in the direction of the microscope constellation. Interacting galaxies is a term used to refer to multiple galaxies that exert a gravitational influence on each other by passing each other or colliding with each other. Some interacting galaxies have shapes greatly distorted by tidal forces, or have spiral arms that extend like long tails.

The most striking feature in this image is the chain of galaxies lined up on the left side of the image. However, according to the European Space Agency (ESA), Arp-Madore 2105-332 actually consists of the large galaxy ESO 402-10 located at the beginning of the column, and the galaxy on the right side of the image. Far from the column ESO 402-9.” The galaxies shown below ESO 402-10 happen to be visible in a straight line from Earth.

This image was created using data acquired by the Hubble Space Telescope’s (HST) Advanced Camera for Sky Surveys (ACS). The Hubble Space Telescope’s observations of Arp-Madore 2105-332 are part of efforts to search for galaxies that could be the subject of future detailed observations by the James Webb Space Telescope (JWST) and the Hubble Space Telescope itself. In July 2018 as part of this initiative.

In addition to the Hubble Space Telescope’s ACS, optical observation data from the Dark Energy Camera (DECam) mounted on the 4-meter Blanco Telescope at the Cerro Tololo Inter-American Observatory were used to create the images. As the name suggests, DECam is an observing device developed for the main purpose of searching for dark energy, and observations for the original purpose of dark energy research were made from 2013 to 2019. Ta.

The European Space Agency published the first image as the “Hubble Space Telescope Image of the Week” on December 11, 2023.
