Galaxy warps light of distant exploding star, greatly increasing its brightness
OXON HILL, Md. — An immense cosmic magnifying glass has given astronomers an unprecedented view of a distant exploding star. The discovery demonstrates that astronomers can spot supernovas that are seemingly too far away to be detected.
The supernova PS1-10afx, located more than 9 billion light-years away, first appeared in 2010 images from the Pan-STARRS1 sky survey. It shined about 30 times as brightly as a typical supernova at that distance. Last April, a team including astronomer Robert Kirshner from the Harvard-Smithsonian Center for Astrophysics published a study that classified PS1-10afx as a new type of ultrabright supernova.
