Notes: Lecture of Scott Bolton, Astro Night, Intrepid Museum, 7/15
In cosmology anything past hydrogen and helium legit is considered very heavy elements. Very small fraction of the universe contains other elements post H and He.
We’re looking at Jupiter because it was the first planet to form.
Jupiter has a lot of heavy elements more than sun, like hydrogen. Looking into this planet can help us understand what happened in early history.
Figuring out ingredient list of planet.
By measuring the trajectory that the planet sets Juno on (aka measurement the path in which Juno travels after Jupiter pass-by) we can figure out how flat the surface is.
By figuring out how flat planet it will lead us to theories of material planet surface is made of. We can tell if it has possible a metallic or rocky core (beyond its gaseous atmosphere).
We can tell where (in retrospect to the sun) and when (how soon after sun formed) that it was created.
Water abundance how much water is inside Jupiter. This obviously means oxygen must be present (in addition to hydrogen & helium already known to be in existence.)
Water ice is efficient for trapping heavier elements. So if we find it then that can make sense for why the gas legit has so many heavy elements!!
Possibility of planet migration?! Aka after Jupiter formed, maybe it was much closer to the sun than where it is today!
Measuring gravitational field can lead to knowing what’s inside core.
By using a gravitational wave detector. Possibly detecting Gravitons?!?-a hypothetical particle.
How deep the great red spot is, which has been around for ~300 years.
