This artist’s concept shows what the young, ‘dead,’ disk galaxy MACS 2129-1 (right) would look like when compared with our Milky Way Galaxy (left). Although three times as massive as the Milky Way, it is only half the size. MACS 2129-1 is also spinning more than twice as fast as the Milky Way. Note that regions of the Milky Way are blue from bursts of star formation, while MACS 2129-1 is yellow, signifying an older star population and no new star birth. Image credit: NASA / ESA / Z. Levy, STScI.
