Star Distribution - Types, Galaxies & Time

    Distribution Stars
AI Thread Summary
The discussion focuses on the percentage distribution of star types (O, B, M, etc.) within our galaxy and various galaxy types, such as globular clusters, and how these distributions evolve over time. Participants express interest in understanding the specific structures of galaxies and their evolutionary relationships. The HR diagram is mentioned as a tool for visualizing star distribution, but it does not provide percentage data. There is a call for resources or insights that can clarify these distributions and their changes over time. Overall, the conversation seeks to deepen knowledge about stellar classification and galactic evolution.

I'm quite interested in finding out the % distribution of stars (by type, viz. O,B,..,M), a) within our galaxy and b) within other galaxy types (ex. globular, etc) - and how these distributions change with time.

Can anyone sate my curiosity (or point me in the right direction) ?

Thanks mgb_phys for you input, but that's not exactly what I was looking for.

I would like to know the particular structures of galaxies, how they evolve and how they relate to other types during their period of evolution.
 

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.
