The Huge Image: Galactic collision offers superb X-ray mild present
‘Tis the season for vacation mild exhibits, and two galaxies about one hundred thirty million mild years from Earth received collectively to placed on a show of their very own. NGC 2207 and IC 2163, each a part of the constellation Canis Main (the Nice Canine), obtained cozy and the “ultraluminous X-ray sources” (ULXs) have been on full show for NASA’s Chandra X-ray Observatory to seize. Mild is created when matter is pulled from stars to a neutron star or black entire, producing X-rays through the heating course of. What’s pictured here’s a composite picture of the encounter with Chandra knowledge in pink, particulars from the Spitzer Area Telescope in purple and information from the Hubble Area telescope in purple, inexperienced and blue (seen as blue, white, orange and brown). The interplay between galaxies additionally options “intense star formation” because of shock waves that spawn in the course of the collision.
