Professor Lawrence Krauss and Professor Michio Kaku explain the physics behind the events in the first second of The Big Bang, events which range from the first fractions of a second after creation: The Plank Era.
The inner planets, Mercury and Venus, orbit closest to the Sun, making them literally an Inferno of heat. NASA and other space agencies have attempted to learn more about these rocky planets. Follow the plucky probes that attempted to decipher the secrets of the Solar System's inner circles of hell.
Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge swarm of neutrinos, blast through the star’s outer layers, causing it to explode. The resulting supernova creates even more heavy elements, scattering them through space. Also, happily, we’re in no danger from a nearby supernova.
