Hubble looks to the Final Frontier on 50th anniversary of “Star Trek”

The TV series “Star Trek” captured the public’s imagination with the signature phrase, “To boldly go where no one has gone before.” The NASA/ESA Hubble Space Telescope doesn’t “boldly go” deep into space, but it is “boldly peering” deeper into the universe than ever before to explore the warping of space and time and uncover some of the farthest objects ever seen.


A fresh perspective on the extraordinary Phoenix galaxy cluster

Galaxy clusters are often described by superlatives. After all, they are huge conglomerations of galaxies, hot gas, and dark matter, representing the largest structures in the universe held together by gravity. New observations of the galaxy cluster SPT-CLJ2344-4243 (or Phoenix Cluster) at X-ray, ultraviolet, and optical wavelengths are helping astronomers better understand this extraordinary system.
