The fate of the Mars InSight lander will all come down to a fiery seven-minute freefall into the Red Planet. Will it survive and reveal new insight into our planetary neighbour, or will the atmosphere of Mars prove to be too much for our new planetary explorer?
The Earth, the sun, the stars, and everything we can see, only comprise five percent of the universe. But what about the other 95 percent? Scientists are puzzling over dark matter and dark energy, the mysterious components that make up the rest.

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.
