Horizon: Strange Signals from Outer Space!

Horizon investigates unusual space signals including the Lorimer Burst, and has exclusive access to researchers at the Green Bank Telescope searching for signals from Tabby's Star

For decades some have suspected that there might be others out there, intelligent beings capable of communicating with us, even visiting our world. It might sound like science fiction, but today scientists from across the globe are scouring the universe for signals from extraterrestrials.

In 2006, husband and wife team Duncan Lorimer and Maura McLaughlin discovered an enigmatic signal from space, known as a fast radio burst. It was a pulse of radiation so bright, it didn’t appear to … Ler mais

Horizon: Secrets of the Star Disc

"It’s the find of a lifetime. Indeed, the find of several lifetimes." - Professor Miranda Aldhouse-Green, University of Wales

This is the extraordinary story of how a small metal disc is rewriting the epic saga of how civilisation first came to Europe, 3600 years ago.

Horizon: Secrets of the Solar System

A look at how new planets being discovered are forcing scientists to rewrite the history of our own solar system

New planets are now being discovered outside our solar system on a regular basis, and these strange new worlds are forcing scientists to rewrite the history of our own solar system. Far from a simple story of stable orbits, the creation of our solar system is a tale of hellfire, chaos and planetary pinball.

It’s a miracle our Earth is here at all.

Horizon: Science Under Attack

Nobel Prize winner Sir Paul Nurse examines why science appears to be under attack, and why public trust in key scientific theories has been eroded

Nobel Prize winner Sir Paul Nurse examines why science appears to be under attack, and why public trust in key scientific theories has been eroded – from the theory that man-made climate change is warming our planet, to the safety of GM food, or that HIV causes AIDS.

He interviews scientists and campaigners from both sides of the climate change debate, and travels to New York to meet Tony, who has HIV but doesn’t believe that that the … Ler mais

Horizon: The Mystery of Dark Energy

Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up

The effects of dark energy were discovered in 1998, but physicists still don’t know what it is. Worse, its very existence calls into question Albert Einstein‘s general theory of relativity – the cornerstone of modern physics.

The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge – someone who can write a new theory explaining the … Ler mais

Horizon: Is Everything We Know About The Universe Wrong?

Investigating the discovery of what is ominously being called 'dark flow', a phenomenon which could mean scientists might have to find a new way of understanding the universe

There’s something very odd going on in space – something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner.

Sasha Kashlinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery’ he says, ‘because this is not something we planned to find’. The accidental discovery of what is ominously being called ‘dark flow‘ not only … Ler mais
