In this episode, they investigate whether we should really be giving up bacon and sausages, after new research suggested they're bad for us. The programme explores why eggs, for years demonised as unhealthy, are now firmly back in fashion and apparently now about as healthy as you can get. Could butter or dripping be next? Plus why white bread isn't necessarily as unhealthy as assumed.
The Large and Small Magellanic Clouds, luminous in the night sky of the Southern Hemisphere, are celestial bodies shrouded in mystery, but recent observations have revealed some startling facts about them. They are survivors of galaxies formed in the early stages of the Universe.
In the darkest reaches of the Solar System, the dwarf planet Pluto lies in a previously unknown region of space until an underground group of scientists took on the establishment and sent a spacecraft to the most distant world that's ever been explored.
We begin our story about 13.7 billion years ago, when all the space, matter, and energy of the known Universe was locked up in a volume less than one trillionth of the size of the point of a pen.
Today Phil helps keep you from ticking off an astronomer in your life by making sure you know the difference between a meteor, meteorite, and meteoroid. When the Earth plows through the stream emitted by a comet we get a meteor shower. Meteors burn up about 100 km above the Earth, but some survive to hit the ground. Most of these meteorites are rocky, some are metallic, and a few are a mix of the two. Very big meteorites can be a very big problem, but there are plans in the works to prevent us from going the way of the dinosaurs.
