AI Thread Summary
Most star systems are not solely composed of light elements, as heavy elements originate from various processes, including supernovae and neutron star collisions. While supernovae distribute heavy elements throughout the galaxy, they are not the only source; ancient stars also contribute to the elemental makeup. The formation of our solar system involved the incorporation of these heavy elements, which may have come from multiple generations of supernovae. Additionally, the concept of metallicity highlights the varying abundance of elements in different stars. Overall, the composition of star systems is complex and influenced by multiple astronomical events.

TL;DR Summary
Looking for a root question of life on other planets.
If we were made from a Supernova (all our heavy elements) does that mean most star systems are made up of just a few of the first elements encluding planets?
Thanks for your time.

There's a very germane article on Wikipedia. Short answer, supernovas are not the only source.

Supernovas blasted heavy elements all over the galaxy. They were incorporated into the Sun (and planets) at the time of their formation.

Our elements may have been through several "generations" of supernovas.
There are some ancient early generation stars (not big enough to supernova) that are low in heavy elements.
 
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.
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...
