Hubble detects two amazingly interacting galaxies more than 200 million light-years away from us…

A new image taken by the NASA and European Space Agency’s Hubble Space Telescope shows Arp 298, which consists of two spectacularly active galaxies.

Arp 298, which includes spiral galaxies NGC 7469 and its smaller companion spiral IC 5283, is located approximately 206 million light-years from Earth in the constellation Pegasus.

The two largest galaxies in the image, NGC 7469, the spiral galaxy with arms (which has the same shape as the Milky Way and may be useful for comparative studies), is host to an active supermassive black hole and a bright ring of star clusters.

The Hubble astronomers explained: “The name Arp in this pair of galaxies indicates that they are both included in the Atlas of Exotic Galaxies compiled by astronomer Halton Arp. His atlas is a gallery of strange and fascinating galaxies containing strange structures, featuring galaxies displaying everything from spiral arms. segmented into concentric rings”.

This pair of interacting galaxies is a familiar sight for Hubble, as an image of merging galaxies was published in Arp 298 in 2008.

This image of Arp 298, which also includes many background galaxies, contains data from three separate Hubble observations.

By combining observations, the Arp 298 was captured in great detail in seven different filters from two of Hubble’s instruments – the Wide Field Camera 3 (WFC3) and the Advanced Camera for Surveys (ACS).

This system will be among the first galaxies to be observed using the James Webb Space Telescope of NASA, the European Space Agency and the Canadian Space Agency as part of science programs in the summer of 2022.

It is noteworthy that the English astronomer John Herschel discovered on November 12, 1784, the galaxy NGC 7469, which was classified as the Seyfert galaxy, a classification of types of galaxies that emit radiation arising from highly ionized gas, and this radiation appears to us in the form of distinct lines in the spectrum. This classification is part of the classification of an active galactic nuclei, which is believed to contain a supermassive black hole.

IC 5283 was discovered by French astronomer Guillaume Begurdin on September 4, 1891.
