Superbubbles from shock waves from supernova or stellar winds?

AI Thread Summary
Shock waves from supernovae and stellar winds generate superbubbles by compressing the interstellar medium, which then recoils and produces a shock wave. The energy from these shock waves is converted to thermal energy through compression, leading to the heating of gas in front of the shock front. Supersonic gas from a star creates a radial shock front that moves outward, compressing and heating the surrounding gas. Additionally, magnetic fields play a crucial role in accelerating charged particles during these shocks, further increasing the gas temperature. This process illustrates the dynamic interactions between stellar phenomena and the interstellar medium.

Can someone explain to me how shock waves from supernova or stellar winds can generate a superbubble? Does the energy from the shock get converted to thermal energy through compression?

Superbubbles arise from the interstellar medium being compressed by means such as you have identified. It then recoils producing a shock wave.

Supersonic gas from a star creates a radial shock front moving away from the star. In front of the shock front the gas is compressed and heated. Behind the front is the hot expanding gas from the star.

MHD (magnetic field) is also important in accelerating charged matter in a shock and therefore further heating the gas.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
