Let me just say this: When scientists say that something exists where it should not have, that means they got 'it' wrong to start with. The discovery of the extraordinary exoplanet LTT 9779b was first announced a month ago. Just 260 light-years away, the planet was immediately pegged as an excellent candidate for follow-up study of its curious atmosphere. But it turns out we didn't even have to wait too long to learn more. LTT 9779b is a little bigger than Neptune, orbiting a sun-like star; fairly normal so far. But two things are peculiar. It's so close to its star, the planet orbits once every 19 hours; and, in spite of the scorching heat it must be subjected to at that proximity, LTT 9779b still has a substantial atmosphere. Infrared observations collected by the now-retired Spitzer Space Telescope included the planet's host star, and astronomers have now analyzed those data, publishing their results in a couple of studies. https://www.livescience.com/astronomers-peer-into-the-atmosphere-of-a-rare-exoplanet-that-shouldn-t-exist.html ................................................................................ #space #science #nature #education #news
