Astronomers have pushed NASA’s Hubble Space Telescope to its limits by finding what is likely to be the most distant object ever seen in the universe. The object’s light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years.


The farthest and one …
