first ⁤3D Map of‍ an Exoplanet reveals⁣ Scorching Temperatures

Researchers have​ generated the first 3D map of ​a planet orbiting another star.

The‌ map reveals an atmosphere with distinct temperature zones-one so‌ scorching that it breaks down water vapor.

“Partially, this result‌ is realy cool because⁢ it’s a presentation of ⁤a new technique,” says Rauscher, ‌University of Michigan associate professor of ⁤astronomy.

“Scientifically, this result is⁢ also really cool as, for this ​particular‌ planet, it gets‌ incredibly hot.”

The team,co-led by ryan Challener⁣ of Cornell University and Megan Weiner Mansfield ⁢of the University of⁢ Maryland,published its findings in the journal Nature Astronomy.

The⁣ team’s temperature map is of ⁣a planet ⁢known as WASP-18b, which is a gas⁢ giant, like Jupiter in⁣ our‌ solar system, but it’s located 400⁣ light ⁢years from‍ Earth. It is indeed so close to its‌ star and so hot that ⁣scientists refer ‌to it as an “ultra‌ hot Jupiter.”

The⁢ team’s effort demonstrates a technique called ​3D eclipse⁣ mapping, or spectroscopic eclipse mapping. The effort ‌builds on a 2D model that ​members of the same team published in 2023, which demonstrated eclipse mapping’s potential to leverage​ highly sensitive observations by‌ the JWST,⁤ Earth’s most powerful space telescope. Operated ‍by NASA, the JWST is also supported by the European Space Agency and the Canadian space agency.

“Eclipse mapping allows ​us to image exoplanets⁢ that we can’t see directly, ⁣because ⁢their host stars are too radiant,” says Challener, a‌ postdoctoral associate at Cornell. “With ⁣this telescope and this new technique, we can start‍ to understand exoplanets ⁣along ‍the same lines as ‍our solar system neighbors.”

similar⁣ to how Earth-based telescopes enabled astronomers to start characterizing Jupiter’s Great Red Spot ⁤long ago, JWST will ​now enable​ scientists to start characterizing more exoplanet atmospheres ⁢with this
