Gas Planets Satellites Solid

AI Thread Summary

Gas planets like Saturn form with solid nuclei that allow them to accumulate gases when positioned far enough from their star. The presence of solid rings and satellites around these gaseous planets is linked to their gravitational influence, which is insufficient for smaller bodies to retain volatiles. The discussion highlights the simultaneous formation of planets and their satellites, emphasizing the unique characteristics of gas giants. Understanding the solid components of gas planets provides insight into their structure and formation processes. This knowledge enhances comprehension of planetary systems in our universe.

I assume that planets and their satellites are created more or less at the same time. Why gaseous planets like Saturn have solid rings and satellites?

Small bodies have too little gravity to hold on to volatiles. Once you have a large enough solid nucleus, and far enough from the star, it can start to accumulate the gasses.

Thank you. I did not know that the gaseous planets have solid nucleus.

Thread 'Illuminating Black Hole Shadows with Dark Matter Annihilation'

Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...

Thread 'Are primordial fluctuations the source of all structure?'

Hello friends . I was asking whether quantum fluctuations created not only large scale cosmological structure but also our human-scale structure. There is no mention and analysis of this aspect of the theory . Please can anyone analyze it for me . How these quantum fluctuations create our human scale density variations and also atomic scale.

Thread 'What happens to information inside a blackhole'

I am 9th-grade student who's curious about blackholes and the idea that they might be connected to white holes. I read about energy conservation and wondered: if black holes don't destroy matter, could the process be linked to a white hole somehow ? I'm not claiming a theory- I just want to understand what current science says about this
