- Is Jupiter made entirely from gas? | Science Questions
The gas is molecular for about 1,000 kilometres in but after that it has to carry the weight of all the overlying layers of gas and it starts to get high temperature, high pressure and becomes as incompressible as a liquid
- Whats at the centre of a gas giant? | Science Questions
Matt - A gas giant is a big gassy planet If you think of something like Jupiter or Saturn, so instead of what we call the terrestrial or rocky planets like Earth, they’re much bigger and they're not rocky, they’re gassy The centre of them - they’re not 100% gas They do have various weird and wonderful things in their centre
- Could I land on a gassy planet like Jupiter? | Science Questions
Marc - In contrast to our planet, gas planets are composed mostly of gas They're also gigantic and the weight of all that gas is tremendous For example, Jupiter is mostly hydrogen and it is enormous, 11 times the diameter of Earth and over 300 times the mass It may have a rocky core that's more than 10 times the mass of Earth
- Could a gas giant turn into a star? | Naked Science Forum
Could a gas giant turn into a star? « Reply #3 on: 18 09 2008 13:30:42 » Neil, just from my memory of 2010, I think the monoliths were "Von Neumann machines" that did some sort of job and were capable of self replication
- What would happen if one of the gas giant planets exploded?
What would happen if one of the "gas giant" planets exploded? « Reply #4 on: 02 04 2010 10:38:19 » Stars do it all the time by fusion, although I wouldn't worry about jupiter as it has no where near the sufficient mass to collapse into a protostar and hence ingnite and explode via fusion
- Can I land on gassy planets like Jupiter? - Naked Scientists
This week we tackle Allana's question: If we were to travel to gas giant Jupiter, would we sink to the core? Or float straight on throu
- Is the gas in gas giants highly compressed? | Science Questions
That gas is very heavily compressed and that's how Jupiter manages to be so very massive Actually it is in a state called metallic hydrogen, where these molecules are so compressed together that they form a lattice and the electrons, rather than orbiting around individual hydrogen nuclei, actually can flow freely through that metallic hydrogen
- Sara Russell: Revelations from the Bennu asteroid
Chris - This is Jupiter, Saturn, Neptune, those sort of gas giant planets, not little rocky planets like us Sara - No, just thinking about the giant planets that make up most of the mass of the planets of our solar system, but yet these are these outer planets
- Titans of Science: Sara Russell | Podcasts - The Naked Scientists
It's probably true that when the giant planets formed, they probably didn't form where we see them now, they may have moved around So they may have moved into the innermost part of the solar system and then moved outwards again Chris - This is Jupiter, Saturn, Neptune, those sort of gas giant planets, not little rocky planets like us
- How long do galaxies take to form? | Science Questions
Maybe the galaxy formation process is only finished when the initial reservoir of gas is converted into stars For galaxies like our Milky Way, that's going to be billions of years in the future James - So Dave, your question has potentially lots of answers: maybe a billion years to create a galaxy, maybe the whole age of the universe, and
