    Atmosphere Jupiter
AI Thread Summary
Jupiter's atmosphere contains hydrogen (H2), which is highly explosive under Earth's conditions, but it does not explode due to the lack of oxygen (O2) necessary for combustion. The discussion highlights that the concentration of gases in Jupiter's atmosphere is too low to initiate a fire reaction. It is noted that more than 75% of the universe's mass is hydrogen, while oxygen constitutes only about 1%, making it unlikely for gas giants to have the right mixture for combustion. The possibility of explosive reactions on other planets is considered, but such scenarios are deemed improbable due to the instability of hydrogen and oxygen mixtures. Overall, the conversation concludes that while theoretically possible, significant explosive interactions in planetary atmospheres are unlikely to occur.

I know it's not a bright question, but I'd like to know the answer as well. I've read that the high atmosphere of Jupiter contains molecules of Hydrogen (H_2). It is well known that (under Earth atmosphere at least), this gas is highly explosive. I just wonder why the atmosphere of Jupiter doesn't explode at least partially. I'm guessing that the concentration of gas on the atmosphere is just way too low to start a fire reaction, but it's only a guess. If it appears to be true, I'd like to know the concentration required to start a fire reaction between Hydrogen molecules. (I know it produces water...in case I'm not specific enough of the gas I'm talking about).

No, H2 explosion needs O2 as well
 
Oh you're right... that's why it produces water. Anyway, isn't it possible to find a planet with an atmosphere mixed with hydrogen and oxygen in such quantities that it can interact violently? I don't think it might occur in the Solar System since Jupiter is just heavy enough to retain the hydrogen in its atmosphere... Maybe big explosions occurs in another planets and we might see them then.
 
More than 75% of the mass of the universe is hydrogen, oxygen only 1%, so big gas planets will be unlikely to have the right mix to make combustion possible.

Too bad... It would also be much less brighter than a little star, so there is no hope to observe it.
I believe planets don't fit the global universe statistics of component elements though.
Now I'm thinking about planets that contains liquid (or ice) H_2 and 0_2. If there is a storm or a cataclysm (say, for example a big cliff falling into the liquefied gases), it would be possible to engender a terrible explosion, but yes, very unlikely to happen.
Thank you both for the clarification. I'm done with this question.
 
Well, such a thing wouldn't be stable anyway. A hydrogen/oxygen mixture is explosive, so a giant ball of it would simplly explode and then be gone. There is no equilibrium to be had like in a star.
 
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...
