US-Chinese Astronomers' Research on Ancient Interplanetary Collision
An international team of scientists have just reported that an ancient planet ten times bigger than the Earth may have crashed hard into Jupiter in the early stages of the solar system.  That cataclysmic collision may be the cause of Jupiter's less dense and more extended core, proportions different than previously thought and just discovered.  The astronomers are working on and analyzing data from the Juno probe that's been circling Jupiter for three years.  It's providing significant new information about our galaxy's largest planet, including the new discovery of the less dense and more extended core of Jupiter.

US-Chinese Astronomers Collaborating
Astronomers from Rice University in Texas and Sun Yat-sen University in China have just released a new theory.  They think that a massive planet collision in the very distant past hit the core of Jupiter and mixed the dense material in the middle of the planet with layers of gas and liquid above it. That would make the core of Jupiter less dense and larger.  That type of planetary collision happened with frequency in the early days of our universe.  The astronomers' extensive computer analyses and 3D modelling suggest this theory is a good probability.
