主題: 14 Herculis c _Webb Directly Observes a Frigid Exoplanet 作者: peter 於 2025-06-12 12:53:24 https://www.universetoday.com/articles/webb-directly-observes-a-frigid-exoplanet The exoplanet, called 14 Herculis c, orbits a star located 60 light years away from Earth. What makes this discovery somewhat unusual is that the planet is one of the coldest ever directly imaged, with temperatures as low as minus 3 degrees Celsius. This is particularly significant because most of the nearly 6,000 known exoplanets that have been directly imaged are extremely hot, often reaching hundreds or thousands of degrees. |
