Recently, astronomers using the 340-megapixel MegaCam on the Canada-France-Hawaii Telescope (CFHT) observed the star-forming region of the famous Orion nebula — located only 1,500 light-years away — and determined that two massive groupings of stars are actually in front of the nebula cluster, separate structures located between it and Earth that may ultimately force astronomers to rethink how the benchmark stars there had formed.
