Rare Cosmic Alignment Reveals Most Distant Star Ever Seen

The Hubble Space Telescope has broken yet another observing record: The famed observatory has found the most distant “ordinary” star ever observed, at an astounding 9 billion light-years from Earth — which means the light scientists see started traveling at least 9 billion years ago. By comparison, the age of the universe is roughly 13.8 billion years.

Normally, stars that far away are too difficult to make out individually; a galaxy or a supernova (star explosion) is much easier to see. But this particular star — classified as an ordinary star, meaning a star on the main sequence of evolution that is fusing hydrogen into helium — came to light thanks to a rare alignment, researchers reported in a new study.
