Astronomers have detected over 5,800 confirmed exoplanets<\/a>. One extreme class is ultra-hot Jupiters<\/a>, of particular interest because they can provide a unique window into planetary atmospheric dynamics. According to a new paper<\/a> published in the journal Nature, astronomers have mapped the 3D structure of the layered atmosphere of one such ultra-hot Jupiter-size exoplanet, revealing powerful winds that create intricate weather patterns across that atmosphere. A companion paper<\/a> published in the journal Astronomy and Astrophysics reported on the unexpected identification of titanium in the exoplanet’s atmosphere as well.<\/p>\n

As previously reported<\/a>, thanks to the massive trove of exoplanets discovered by the Kepler mission, we now have a good idea of what kinds of planets are out there, where they orbit, and how common the different types are. What we lack is a good sense of what that implies in terms of the conditions on the planets themselves. Kepler can tell us how big a planet is, but it doesn’t know what the planet is made of. And planets in the “habitable zone” around stars could be consistent with anything from a blazing hell to a frozen rock.<\/p>\n

Like the Transiting Exoplanet Survey Satellite<\/a> (TESS), Kepler identifies planets using the transit method. This works for systems in which the planets orbit in a plane that takes them between their host star and Earth. As this occurs, the planet blocks a small fraction of the starlight that we see from Earth (or nearby orbits). If these dips in light occur with regularity, they’re diagnostic of something orbiting the star.<\/p>\n
