This image shows the huge galaxy cluster MACS J1149.5+223, whose light has taken over five billion years to reach us.

Highlighted is the position where the star LS1 appeared – its image magnified by a factor 2000 by gravitational microlensing. The galaxy in which the star is located can be seen three times on the sky – multiplied by strong gravitational lensing.
