This Hubble image shows the galaxy cluster MACS J1149.5+223, whose light has taken over 5 billion years to reach us. Highlighted is the position where the Icarus star appeared -- its image magnified by a factor 2,000 by gravitational microlensing. The spiral galaxy in which the star is located can be seen three times on the sky -- multiplied by strong gravitational lensing. Image credit: NASA / ESA / S.
