[astrogeology] measuring atmospheric density

AI Thread Summary
The discussion centers on understanding the equation g/cm^3, which represents density as mass per unit volume. Participants clarify that this equation is used to measure atmospheric density on planets, including Saturn's moon Enceladus. There is confusion about whether the inquiry pertains to the derivation of atmospheric density or the origins of the density equation itself. The equation's application in the article is questioned, as it does not seem to be explicitly referenced. Overall, the conversation highlights the importance of density in astrogeology and its relevance to planetary atmospheres.

Can someone explain the equation g/cm^3 in layman's term? I was reading up on this article on Saturn's moon Enceladus, having heat, and the first thing i though was the gravitational tuggin from Saturn and it's other moons. And i came across this equation and seem like it's used to base density levels of atmospheres on planets. Also how did they come up with this equation?

noone, eh?
 
\rm{g}\over\rm{cm}^3 is the units for density, which is the mass per unit volume.

Not sure what you are asking here. Are you asking how they derive the atmoshperic density of the planets, or how they came up with the equation for density? I can't see where they have used it in the article either.
 

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?'

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...
