DShomshak Posted December 18, 2018 Report Share Posted December 18, 2018 Last week the BBC aired a short interview with a NASA representative about the Juno spacecraft's discoveries at Jupiter. Interesting but frustrating, as the NASA rep didn't have a lot of time and wasn't very good at explaining, and the BBC presenter didn't know enough to ask clarifying questions. If I understood correctly, though, one unexpected discovery is that Jupiter's magnetic field is asymmetrical in ways that cannot yet be explained. But it may have something to do with evidence that there's something very strange about Jupiter's core. If the planet even has a core (which they aren't sure about), it might be, in the NASA rep's words, lumpy. I'd like to look for an article with better information, but my internet connection is very slow and generally sucks. I hope someone else can post a link to something good.

Yeah, it wasn't a choice between "8 planets or 9 planets" it was a choice between "8 planets or 900 planets."

Cancer Posted December 19, 2018 Report Share Posted December 19, 2018 At this point I don't trust mass estimates for the trans-neptunian stuff (by that I mean: total mass in that population). I think our knowledge is way too incomplete at this point. The main asteroid belt we know a lot better, and it has one dwarf planet (Ceres). The main belt total mass is about 4% of the Moon, and the Moon's mass is about 1/80 that of the Earth; the biggest four objects account for about half the mass. Mars is about 1/10 of Earth's mass, so a few hundred trans-neptunian dwarf planets combined probably gets up to about a Mars mass. I should probably go back and check that estimate with the handful of TNO masses we have. tkdguy and DShomshak 1 1 Quote Link to comment Share on other sites More sharing options...

I personally would have grandfathered Pluto in the planet category, but in the long run, nothing has really changed apart from the new classification.

DShomshak Posted December 19, 2018 Report Share Posted December 19, 2018 Thanks be to my local library. This looks like a good one-stop shop for Juno news: Latest News About the Juno Mission to Jupiter | NASA Solar System ... https://www.space.com/topics/nasa-juno-jupiter-mission-news Cached NASA's Jupiter-bound Juno probe will study the gas giant's atmosphere, magnetosphere and gravitational field. Juno will orbit Jupiter for about a year. tkdguy 1 Quote Link to comment Share on other sites More sharing options...
Lord Liaden Posted December 20, 2018 Report Share Posted December 20, 2018 Jupiter could be surveyed for a hundred years, and the job would still be barely begun. Once human beings get physically out into the solar system, I expect Jupiter and its moons to be a major focus of our attention and projects to exploit.

Cancer Posted December 20, 2018 Report Share Posted December 20, 2018 The radiation environment around Jupiter is nasty enough you have to do that exploration from distance ... or with sacrificial probes. Exactly how long Juno lasts will be information by itself. Quote Link to comment Share on other sites More sharing options...

Christopher Posted December 26, 2018 Report Share Posted December 26, 2018 Ultima Thule - an object New Horizon will pass by around New Year - is giving us it's first mystery. We have already determined that it is not a sphere. So we have been looking at it to figure out what light-curve it emits, to have more ideas in wich way it was not a sphere. But there is no light curve. The light reflection is constants, as if it was a sphere. http://pluto.jhuapl.edu/News-Center/News-Article.php?page=20181220 pinecone 1 Quote Link to comment Share on other sites More sharing options...
