Shining like a bright beacon in the middle of the sea galaxies, Arp 220 lights up the night sky in this image from NASA’s James Webb Space Telescope.
actually two spiral galaxies in the process of merging Arp 220 it glows most brightly in infrared light, making it an ideal target for a telescope. It is an ultra-luminous infrared galaxy (ULIRG) with a luminosity of over a trillion suns.
By comparison, according to NASA, our Milky Way galaxy has a much more modest luminosity of about ten billion suns.
What do we know about the phenomenon
It is located 250 million light-years away in the constellation Serpens. Arp 220 it is object number 220 in Halton Arp’s Atlas of Odd Galaxies. It is the closest ULIRG and the brightest of the three galaxy mergers closest to Earth.
Clash of two spiral galaxies It started about 700 million years ago. This caused a huge burst of star formation. About 200 huge star clusters lie in a dusty, compact region about 5,000 light-years across (about 5% of the Milky Way’s diameter). The amount of gas in this tiny region is equal to all the gas in the entire Milky Way.
Previous radio telescope observations have revealed about 100 supernova remnants spanning less than 500 light-years. NASA’s Hubble Space Telescope has discovered the nuclei of host galaxies 1,200 light-years apart. Each of the nuclei has a spinning ring of star formation that emits the dazzling infrared light seen in this image. James Webb. This blinding light creates diffractive bursts, a feature of star formation that dominates this image.
On the fringes of this confluence, Webb discovers faint tidal tails or material extracted from galaxies gravity, represented in blue, is indicative of a galactic dance in progress. Organic material, represented by a reddish-orange color, appears in streams and filaments along Arp 220.
James Webb saw Arp 220 with a near infrared camera (NIRCam) and a mid infrared (MIRI) instrument. (Europe Press)
