00:00Hold on to your telescopes, Jupiter used to be gigantic!
00:03Around 3.8 million years after our solar system began, Jupiter was a true Titan.
00:08This gas giant was twice its current size, with a volume that could fit over 2,000 Earths.
00:13And get this, its magnetic field was about 50 times stronger than it is now.
00:18Scientists Constantine Batygin and Fred C. Adams figured this out
00:21by studying the orbits of Jupiter's inner moons, Amalthea and Thebe.
00:25As the Sun's protoplanetary nebula dissipated, Jupiter began to contract,
00:30shrinking to its present size and spinning faster.
00:34Jupiter's massive early self and powerful magnetic field played a huge role in shaping our solar system.
00:39It influenced the formation and orbital paths of other celestial bodies acting as a cosmic architect.
00:45Even now, Jupiter continues to slowly shrink as it cools.
00:49These insights help us understand not just Jupiter but the formation of gas giants
00:53and the dynamic history of our solar system. Pretty cool, right?
00:56Who knew our favorite giant planet had such a colossal past?
