Young Jupiter hit by a new born planet

The launch of, Friday (08/16/2019), a colossal clash between young Jupiter and a planet still formed in the solar system about 4.5 billion years ago, could explain the shocking reading from NASA's Juno spacecraft.

Astronomers at Rice University and Sun Yatsen University of China explain that previously confusing Juno gravity readings showed that Jupiter's nucleus was less dense and wider than expected.

"That shows that
something that happened moved Jupiter's core and that's where the impact is
giants play a role, "said Andrea Isela, one of the astronomers at Rice University.

The crash of young Jupiter

Member of China Sun Faculty
Yatsen University, Shang-Fei Liu said the calculations include estimates
the likelihood of a collision is in a different scenario and distribution
impact angle.

In all cases, Liu and
his colleagues found that there was a 40% probability of Jupiter
the young will swallow the planetary embryos in their first few million years.

In addition, the planet produces
"Strong gravity focus", which occurs massively, leading to a collision
this happens more often.

Isela said, scenario
the collision became more interesting after Liu released a 3D computer model
shows how the collision will affect the core of Jupiter.

"Because he's solid, he's coming
with a lot of energy. The blow was like a bullet through the atmosphere and
for the core directly, ”Isela said.

Research on young Jupiter

Isela said theories
the leading formation of the planet shows that the young Jupiter
begins as a dense, rocky or icy planet, which then collects the atmosphere

He also added that the calculation
for this influence 4.5 billion years ago.

The Juno mission is intended for
helping scientists better understand the origin and evolution of Jupiter.
The spacecraft, launched in 2011, has brought about tools
maps Jupiter's gravitational and magnetic fields and examines internal structures
