An international team of researchers has successfully used NASA’s James Webb Space Telescope to map the weather on the hot gas-giant exoplanet WASP-43 b. Precise brightness measurements over a broad spectrum of mid-infrared light, combined with 3D climate models and previous observations from other telescopes, suggest the presence of thick, high clouds covering the nightside, […]
A cutting-edge tool to view planets outside our solar system has passed two key tests ahead of its launch as part of the agency’s Roman Space Telescope by 2027.
Astronomers using NASA’s Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. “This would be the first time that we can directly show through […]
Roman’s long-term sky monitoring, which will enable these results, represents a boon to what scientists call time-domain astronomy, which studies how the
Researchers using NASA’s James Webb Space Telescope have detected evidence for quartz nanocrystals in the high-altitude clouds of WASP-17 b, a hot Jupiter
