c. DOO J1142+1527
d. KOO J1142+1527

ANSWER: MOO J1142+1527
Astronomers discovered a giant galaxy in the remote parts of the universe said to be the most massive structure found 8.5 billion light years away. This cluster was spotted using NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE). These clusters are galaxies bound together by gravity. As they acquire new members, clusters increase in size over time. The galaxy cluster called Massive Overdense Object (MOO) J1142+1527 was present 8.5 billion years ago, long before Earth was formed.
