Detecting exoplanets at all is difficult—they typically emit much less than 1% of a host star's brightness. Eclipse mapping requires measuring small fractions of that total as a planet circles behind ...

What can a 3D map of an exoplanet’s atmosphere teach astronomers about the planet’s formation, evolution, and composition? This is what a recent study published in Nature Astronomy hopes to address as ...

"Our approach gives astronomers an idea of how many spots a star might have, where they are located, and how bright or dark they are." When you purchase through links on our site, we may earn an ...

For the first time, scientists have developed a 3D map of an atmosphere belonging to a planet outside our solar system. Attached to a particularly mysterious alien world, the newly charted atmosphere ...

Exoplanets are planets outside Earth's solar system that most often orbit a star. Astronomers have managed to bring an exoplanet into unprecedented focus by using a technique the researchers call 3D ...

Astronomers have generated the first three-dimensional map of a planet orbiting another star, revealing an atmosphere with distinct temperature zones—one so scorching that it breaks down water vapor, ...

ITHACA, N.Y. – Astronomers have generated the first three-dimensional map of a planet orbiting another star, revealing an atmosphere with distinct temperature zones – one so scorching that it breaks ...
