James Webb Space Telescope Captures Stunning Image of Arp 220

In a new image released on April 17, 2023, NASA's James Webb Space Telescope has captured a stunning image of Arp 220, two spiral galaxies in the process of merging. Arp 220 shines like a beacon in the night sky and is the nearest ultra-luminous infrared galaxy (ULIRG) to Earth. It is located 250 million light-years away in the constellation of Serpens.

Interacting Galaxies Arp 220

Arp 220 is the result of a collision between two spiral galaxies that began 700 millions years ago. Located about 250 million light-years from Earth, it is one of the nearest galaxy mergers to our planet.

Observada la instantánea de un enorme choque entre dos galaxias espirales

Una impresionante colisión de dos galaxias espirales brilla en el infrarrojo con la luz de más de un billón de estrellas. Llamadas Arp 220, las galaxias en colisión provocaron un tremendo estallido de nacimiento de estrellas. Cada uno de los núcleos galácticos combinados está rodeado por un anillo giratorio de formación de estrellas que emite una luz deslumbrante que el telescopio espacial James…

A star? Actually, this is the cores of two colliding galaxies filled with millions of stars! Collectively called Arp 220, the galactic smashup ignited a tremendous burst of star birth. The combining galactic cores are each encircled by a rotating, star-forming ring that blasts out brilliant light. The James Webb Space Telescope captured the light of Arp 220, which shines in infrared with the brightness of more than a trillion suns. The light is so glaring that it creates diffraction spikes in Webb’s image—the starburst feature that dominates our view.

ALT TEXT: A black, deep-space background is punctuated with more than a hundred randomly spaced red, white and orange galaxies in this astronomical image. These galaxies are various shapes and apparent sizes. Dominating the foreground is an object that at first appears to be a brilliant, 6-pointed, orange star surrounded by wisps of orange gas and bluish purple nebulosity. In reality, what seems to be a star is actually two colliding galaxies with merging cores. The brilliant light from the star-formation surrounding these cores creates diffraction spikes — the prominent starburst feature. Several tiny, whitish yellow regions appear almost dead center on this feature. On the outskirts of the merger are faint, grainy, nearly transparent areas that look like bluish purple clouds. Reddish orange streams and filaments appear across the foreground object.
