Science’s Greatest Mysteries on BBC Select

Episode 1 – The Far Side of the Moon

Why is the far side of the Moon so completely different from the surface we see?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.
This documentary explores the mystery of the far side of the Moon and follows three different theories attempting to make sense of it. New science, and old lunar samples, could unlock the mystery.

Episode 2 – Solar Superstorms

What damage could ferocious solar explosions wreak on our vulnerable planet? 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. These solar superstorms have the potential to cause blackouts, satellite malfunctions and more. Understanding the mystery of these superstorms is required to ensure our survival.

Episode 3 – The Age of the Universe

How can there be a star that appears to be much older than the universe itself? 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. It led to some soul searching in the astronomical community as scientists realized that their estimations of the universe’s
age were potentially flawed. But could this mystery ever be solved?

Episode 4 – Tutankhamun’s Space Dagger

Why was a dagger made with iron from space found with the mummy of Tutankhamun? In 1925, explorer Howard Carter miraculously discovered the tomb of Egyptian pharaoh Tutankhamun. Amongst the many treasures that were unearthed were a 12 pair of daggers lodged within the burial wrappings of the teenage king. Researchers
were shocked to find that the daggers appeared to be made from iron that came from space. But how did these ancient people achieve this?

Episode 5 – Is There Life on Mars?

Could the proof of life on the Red Planet help us to better understand life on ours? 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 that there was life on the planet, but others were far more skeptical. As Martian exploration has intensified, proof of life there could help us understand how life on Earth was established.

Episode 6 – Why Do We Exist?

The discovery of one particular substance could unravel the whole mystery of existence. 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. If scientists can unravel the mysteries of antimatter, it could help us understand why there is life on this planet and possibly on planets elsewhere. But trying to study antimatter is a fiendishly difficult task.
