In 1996, scientists discovered what may be the strangest stone ever found, in an equally strange section of the Sahara desert that’s littered with unique yellow glass. Nicknamed the Hypatia stone, the relic was later found to be extraterrestrial in origin, but was unlike any known kind of meteorite or comet. A new study has deepened the mystery even further, finding that Hypatia could predate the formation of the Solar System, or have interstellar origins.
Though the couple billion-dollar Curiosity rover seems to get all the attention on the red planet these days, it’s one of the veteran rovers on Mars that captured an event that is stunning scientists and space fans alike.
The crux of the issue surrounds these photos snapped by the rover Opportunity on two different missions.
