Bizarre alien planet has layered atmosphere of vaporized metals
Scientists have spotted the first evidence of an alien world with an atmosphere that's layered like Earth's — although perhaps a little too toasty for human tastes.
The planet, dubbed WASP-189b, isn't a new discovery. Scientists already knew that the world, which lies about 322 light-years from Earth, is a gas giant that orbits its star 20 times closer than Earth does the sun, making it a sweltering world. And in a new study of the exoplanet, scientists found the first hint that such a body sports a complex atmosphere like our own.
"In the past, astronomers often assumed that the atmospheres of exoplanets exist as a uniform layer," Jens Hoeijmakers, an astrophysicist at Lund Observatory in Sweden and a co-author on the new research, said in a statement released by the University of Bern in Switzerland, where some of the scientists are based. "But our results demonstrate that even the atmospheres of intensely irradiated giant gas planets have complex three-dimensional structures."
