Barium discovered in the atmosphere of an exoplanet

[frogwoman]

Been reading/watching a lot of stuff about space recently and especially exoplanets. I think this sort of thing is pretty cool. Anyway they just found Barium in the upper reaches of atmosphere of a planet, which is quite interesting as it is heavier than iron so shouldn't really be up there. Its thought the planet is tidally locked like the moon is to earth, and hot enough for iron droplets to fall as rain.

Astronomers discover heaviest exoplanet element yet on alien world so hot it rains iron

Astronomers have detected barium around the ultra-hot gas giants WASP-76 b and WASP-121 b.

Reminds me of the early days when they first started observing exoplanets. There was a definite bias towards large, hot planets which orbited very close to their stellar primary.

I'm hoping that the JWST will be able to further push the envelope on these kinds of observations, and start recording the atmospheric composition of planets in colder orbital conditions.

Not sure factor 50 would be sufficient.

Yeah, lava cake would take on a new meaning here

You'd cool down on a hot day with a nice barium and iron ice cream and when it got too chilly you'd have a cup of molten lava to warm up

Makes me wonder what life would be like on the earth if we had one in the solar system NoXion

Last I heard the working hypothesis was that these "hot Jupiters" formed by coalescing at the edges of the star system before moving inwards (the migration hypothesis), which would probably involve the more inward planets being disturbed as the gas giant moves into position. But the story behind the formation of these kinds of worlds may be more complicated than that. So there might be a star system out there with hot Jupiter and an Earthlike planet that did not get shot into a cosmic pocket during a game of planetary pool. Such a gas giant might occasionally be visible from the Earthlike world during sunset and sunrise.

I don't know if a typical hot Jupiter orbits at a distance where it would prevent planets like Mercury from hanging around. Mythologies on such a world would be different. This new light would be closer than the messenger, perhaps a personal attendant to the solar deity.

Handy if you need an enema..

If we think gas bills are high here the bill for running air con there would be astronomical.

Someone needs to write this sci fi lol

I like a hot Jupiter, glad I'm not anywhere near one though

 

[frogwoman]

I'm writing a sci fi story and decided to include this planet
