Astronomers Discover Alien World Hotter Than Most Stars (vanderbilt.edu)
Science_afficionado writes: An international team of astronomers has discovered a planet like Jupiter zipping around its host star every day and a half, boiling at temperatures hotter than most stars and sporting a giant, glowing gas tail like a comet. From a report via Vanderbilt University: "With a day-side temperature peaking at 4,600 Kelvin (more than 7,800 degrees Fahrenheit), the newly discovered exoplanet, designated KELT-9b, is hotter than most stars and only 1,200 Kelvin (about 2,000 degrees Fahrenheit) cooler than our own sun. In fact, the ultraviolet radiation from the star it orbits is so brutal that the planet may be literally evaporating away under the intense glare, producing a glowing gas tail. The super-heated planet has other unusual features as well. For instance, it's a gas giant 2.8 times more massive than Jupiter but only half as dense, because the extreme radiation from its host star has caused its atmosphere to puff up like a balloon. Because it is tidally locked to its star -- as the moon is to Earth -- the day side of the planet is perpetually bombarded by stellar radiation and, as a result, it is so hot that molecules such as water, carbon dioxide and methane can't form there." The findings have been published in the journal Nature.
Simple enough : we get massive amount of data from scoped research as a side dish, and a trove of nameless PhD who've been told to publish or perish. I say : publish anything remotely interesting.
But c'mon man, can't you find it a least puzzling and a new onlook on space the fact that the frontier between a star, a comet, and a planet becomes that much more hazy ?
Can't you marvel at the idea of giant ball of proto plasma weezing around a sun with a trail behind ?
And that all these findings are due to serendipity ?
I diagnose you, sir, with a broken dream organ.
If everyone thought like you did, we'd still be in the dark ages.
You never know what research will find, but because of all that research of no known future application was done, we have a world of computers, medicine, worldwide communication, and a multitude of other wonders.
The ad hominem attacks will prove that I'm right and that this finding is utterly useless.
Wait, so every time someone calls you names, that means your arguments become correct? I call your ad hominem and raise you a non sequitur.
Every end has half a stick.
With a day-side temperature peaking at 4,600 Kelvin (more than 7,800 degrees Fahrenheit)
I think they finally found the homeworld of AMD processors. ;)
Anons need not reply. Questions end with a question mark.
If those numbers are correct and "density" refers to the mean density over the entire planet, then that would make this the largest planet ever discovered at 7.6 times the radius of Jupiter. As far as I can tell the record was HD 100546 b at 6.9 times the size of Jupiter. Odd that the neither the article nor the summary mentions breaking that record. In light of that, I have a suspicion that someone reported the numbers incorrectly and that it's only 1.8 times the mass of Jupiter. Maybe I missed it but I can't spot the actual mass or size in the article anywhere.
Seriously. Look at the icons near the title.
Your first issue is that you have conflated science and engineering. Your second issue is that you know little of either. Your ultimate issue is that you think like you write, and your writing is incoherent.
You're also wrong about almost everything you say, but I'm not interested in pig-wrestling today.
Those who advocate genocide deserve every protection afforded by law, and none afforded by common human decency.
