NASA’s James Webb Space Telescope captures spectacular image of ultra-bright merging galaxies
NASA’s James Webb Space Telescope has taken a picture of two merging galaxies known as Arp 220, located 250 million light-years away from Earth. The smash-up of two galaxies is an ultra-luminous infrared galaxy with a luminosity of over a trillion suns. The two galaxies began colliding about 700 million years ago, leading to an enormous burst of star formation, creating 200 star clusters in a 5,000 light-year across region. The amount of gas in this region is equal to all the gas present in the Milky Way. The telescope viewed the galaxy with the Near-Infrared Camera and Mid-Infrared Instrument. The latest picture of Arp 220 has more detail than the 2008 photograph captured by the telescope. Previously, the Webb telescope captured an image of Uranus, showing its bright features in its atmosphere and 11 of its 13 known rings.
