Death Dive to Saturn

   2019    Science
Almost everything we know today about the beautiful giant ringed planet comes from Cassini, the NASA mission that launched in 1997 and arrived at Saturn in 2004. Since then, the space probe has been beaming home miraculous images and scientific data, revealing countless wonders about the planet, its rings and 62 moons - including some that could harbor life. When the mission approached its final days, it attempted one last set of daring maneuvers - diving between the innermost ring and the top of Saturn's atmosphere.
Aiming to skim less than 2000 miles above the cloud tops, no spacecraft has ever gone so close to Saturn, and hopes were high for incredible observations that could solve major mysteries about the planet's core. But such a daring maneuver comes with many risks and is no slam dunk. In fact, slamming into rocks in the rings is a real possibility. Join NASA engineers for the tense and triumphant moments as they find out if their bold re-programming has worked, and discover the wonders that Cassini has revealed over the years.

The Invisible Universe

   2018    Science
It is one of the most unnerving discoveries in space science - that most of the universe is missing. We live in a material world, so instinctively we know what normal matter is - the world around us, the planets, stars and interstellar dust. But scientists currently estimate that 95 per cent of everything in the universe is actually - one way or another - invisible.
Some of this is ordinary matter that we just can't easily see. But there's also stuff that's much more weird. For instance, there's a new kind of matter we think is out there, but whose very existence is still largely hypothetical - dark matter. And most mysteriously of all, scientists think there is an unknown form of energy pervading the universe that we know so little about, all it has so far is a name - dark energy. Embark on a tour of this invisible universe, and shows how its existence - or lack of it - will define the fate of the entire universe.

The Quasar Enigma

   2018    Science    HD
Mysterious lights shine out from the edge of space, brighter than a trillion suns. They had to be the brightest objects we've ever seen in the universe, putting out amounts of energy that we couldn't possibly explain. So powerful, they can incinerate planets and rip stars to pieces. These are among the most mysterious and most energetic phenomenon in the universe. They can destroy galaxies, but may also be the key to their survival. These objects are a hotbed of all kinds of crazy physics. These celestial powerhouses are called quasars, and we may owe them our very existence.
