Discussion Overview

The discussion revolves around the impact of Comet Shoemaker-Levy 9 with Jupiter, exploring the nature of the collision, the characteristics of Jupiter's atmosphere, and the frequency of impacts on the planet. Participants also touch on related recent events involving collisions with Jupiter.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants question how the impact occurred given Jupiter's gaseous nature, wondering if pressure slowed the comet down or caused it to explode.
  • There is a suggestion that the size of the impacts observed from telescopes could be attributed to Jupiter's immense gravity and atmospheric conditions.
  • One participant asserts that Jupiter does have a small rocky core, countering an earlier claim that it does not.
  • Another participant clarifies that the comet fragments did not reach Jupiter's core but instead imparted their kinetic energy to the planet's dense atmosphere.
  • There is mention of a recent collision with Jupiter and links to news articles about multiple impacts, suggesting that Jupiter may be experiencing more frequent collisions than previously thought.
  • Participants note the advancements in amateur astrophotography that allow for more frequent detection of impacts on Jupiter.

Areas of Agreement / Disagreement

Participants express differing views on the nature of Jupiter's core and the mechanics of the comet's impact. There is no consensus on the specifics of how the impact occurred or the implications of Jupiter's atmospheric properties.

Contextual Notes

Some statements rely on interpretations from documentaries and may not reflect established scientific consensus. The discussion includes varying assumptions about Jupiter's core and the dynamics of impacts.

Just curious how this impact would have happened ? Since Jupiter has no core & is all dense gas.

Would the pressure have slowed it down until it just exploded? How did the impacts seen from telescope get so big? Was it the extreme winds blowing everything around? Or was it due to a lot more energy with the collision from Jupiter's huge gravity?

thanks

Was this the comet that hit last Thursday?
 
Jupiter does actually have a core, its very small rocky one
 
Dav333 is talking about Shoemaker-Levy 9, which collided with Jupiter in July 1994. It hit Jupiter's atmosphere. Look at it this way, Dav333: Most meteoroids which collide with the Earth don't hit the Earth's surface. They burn up long before they reach the surface. Jupiter's atmosphere is much denser and much, much, much deeper than is the Earth's. Those comet fragments had no chance of reaching Jupiter's core. They imparted all of their kinetic energy to Jupiter's atmosphere.
 
thanks for replies.

I only say Jupiter has no solid rocky core as I watched a recent documentary extreme planets I think it was & it says its core is some strange liquid metallic hydrogen conducting electrical currents.
 
More collisions with Jupiter

When the OP first posted, a new collision with Jupiter had occurred

and there had been a collision last year

Recently on Aug 20, another collision was caught by an amateur astronomer.

Jupiter may be collecting objects more oftent than previously thought

It's cool that so many are being detected: Amateur astrophotography has gotten so good and so pervasive, that there is almost always a telescope with a camera pointed at Jupiter these days, ready to capture such events.
