NASA’s Webb Measures the Temperature of a Rocky Exoplanet
2023年3月27日 · An international team of researchers has used NASA’s James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet’s thermal emission: heat energy given off in the form of infrared light detected by Webb’s Mid-Infrared Instrument (MIRI).

NASA’s Webb Maps Weather on Planet 280 Light-Years Away
2024年4月30日 · This set of maps shows the temperature of the visible side of the hot gas-giant exoplanet WASP-43 b, as it orbits its star. The dayside of the planet is visible just before and after it passes behind the star.
For Hottest Planet, a Major Meltdown, Study Shows
2020年1月24日 · With a surface temperature of 7,800 degrees Fahrenheit (4,300 degrees Celsius) — hotter than some stars — this planet is the hottest found so far. Now, a team of astronomers using NASA’s Spitzer space telescope has found evidence that the heat is too much even for molecules to remain intact.
How Did The JWST Determine The Temperature Of An Exoplanet?
2023年11月1日 · To obtain the planet’s temperature, astronomers first measure this decrease in brightness, also called the eclipse depth, using the exoplanet’s light curve. They find the planet’s flux during the daytime using this depth value. Astronomers then used Planck’s radiation law to determine the temperature.
NASA Hubble Maps the Temperature and Water Vapor on an Extreme Exoplanet
2014年10月8日 · A team of scientists using NASA’s Hubble Space Telescope has made the most detailed global map yet of the glow from a turbulent planet outside our solar system, revealing its secrets of air temperatures and water vapor. Hubble observations show the exoplanet, called WASP-43b, is no place to call home.
Webb Rules Out Thick Carbon Dioxide Atmosphere for Rocky Exoplanet
2023年6月19日 · With a dayside temperature of roughly 380 kelvins (about 225 degrees Fahrenheit), TRAPPIST-1 c is now the coolest rocky exoplanet ever characterized based on thermal emission. The precision necessary for these measurements further demonstrates Webb’s utility in characterizing rocky exoplanets similar in size and temperature to those in our ...
NASA Gets a Rare Look at a Rocky Exoplanet’s Surface
2019年8月19日 · A new study using data from NASA’s Spitzer Space Telescope provides a rare glimpse of conditions on the surface of a rocky planet orbiting a star beyond the Explore Search
Temperature of a rocky exoplanet measured - ScienceDaily
2023年3月27日 · The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere. An international team of...
Unfortunately, surface temperature is not currently measurable for any known exoplanet. Theoretical at-tempts to explore these temperatures use simple energy balance models to computational demanding General Circulation Models (GCMs).
