How the Solar System Was Born — and Why Mars Blames Jupiter | Part 1

4.6 billion years ago there was no Sun — just a cold, sleepy cloud of gas and dust. Then everything began to fall... In Part 1 of Solar System Origins, Timbre plays the oldest record he has: how a cloud became the Sun and a spinning disk, why ice past the frost line let giant planets grow, how a very hungry young Jupiter carved a gap in the disk — and how one leading idea, the Grand Tack, could explain why Mars is so small.
