Science's Greatest Mysteries: Season 1

In 1959, a Russian space probe took the first ever images of the far side of the Moon. The iconic pictures shocked the science world, revealing it to be completely different to the visible side.

Ferocious explosions on the surface of the Sun can release clouds of electrically charged particles containing energy equivalent to millions of nuclear bombs. And when these particles reach Earth, havoc ensues.

In 1989, the space telescope Hipparcos focused on a single star. It then made an unbelievable discovery. Known as the Methuselah star, this celestial body appeared to be older than the universe itself.

In 1925, explorer Howard Carter miraculously discovered the tomb of Egyptian pharaoh Tutankhamun. Amongst the many treasures that were unearthed were a pair of daggers lodged within the burial wrappings of the teenage king.

In 1996, the scientific community was rocked by the discovery of a meteorite. The object appeared to come from Mars and researchers claimed there were traces of fossils inside. The controversial find suggested there was life on the planet.

Our existence doesn't really make sense. When the universe was created, matter and a substance called antimatter should have obliterated each other. But that didn't happen.
