Comet of the Century

   2013    Science
Comet ISON can well be the brightest and most spectacular comet for a generation. It appeared above the eastern horizon from December 2013 as a glorious streak across the sky. ISON has been travelling towards the sun for ten thousand years and will make only one orbit through its corona before disappearing off into the outer solar system.
But as well as providing a great spectacle, ISON's tail of vaporised gas and water, hundreds of millions of kilometres long, will give insights into some of the greatest mysteries of science; it will help explain the origins of the solar system, whether earth's water was delivered on comets and even whether we are alone in the universe.

Comets: Frozen Wanderers

   2012    Science
We think of comets as beautiful glowing balls of light streaking across our skies with their long sweeping tails, yet comets are so much more than just a cosmic firework display. Comets have a uniquely important place in modern science. As time machines from the early universe, they could hold the key to unlock the secrets of the cosmos. Comets could even be the origin of life itself. We follow the incredible odyssey of a comet as it sails through the solar system, watching it's every move as it evolves from a dormant chunk of ice and rock into a tumbling, violently active nucleus engulfed in a gaseous haze. What we learn is a revelation; comets are even more mysterious and fascinating than we had ever imagined.

   2018    Technology    HD
Minerva B is a small rocky planet just like earth, where spacecraft Artemis has found water, organic molecules, and complex creatures. Is there something more to find?
'I am the mind of the spaceship, alone among the stars. 50 years ago, from a planet far away, the planet you call home, I launched. A journey of 28 trillion miles across the yawning time of space to the exoplanet, Minerva B: a small, rocky planet, much like Earth, but orbiting another sun. Here, I have found water, organic molecules, and microorganisms. When the news of my discovery reaches Earth years from now, some of you will be amazed. But others will remain unsatisfied, and you will ask, have I not found animals or birds? Have I not met intelligent life like us? And so, my search continues. I will find life of marvellous complexity, and the traces of a devastating loss.'
