Iron drops rain down over gas giant

-

Drops of molten iron rain heavily down though the atmosphere of the Jupiter-like OGLE-TR-56b exoplanet, according to astronomer­s. The gas giant's atmosphere contains iron atoms. As the atmospheri­c temperatur­es reach approximat­ely 1,700°C, the iron can form clouds, which could in principle result in precipitat­ion in the shape of iron drops. The planet was discovered in 2002 and confirmed in 2003. Measuremen­ts showed that OGLETR-56b only takes 29 hours to

orbit its star, so one year correspond­s to only 29 hours, which is very brief.
