Exoplanet discovered in 2020 has the coldest temperatures ever measured, scientists say
An exoplanet discovered in 2020 contains the coldest temperatures ever measured on a planetary body, according to scientists.
The planet, called WD 1856+534 b, is a gas giant exoplanet the size of nearly 14 Jupiters and nearly six times its mass, according to NASA. Recent observations from the James Webb Space Telescope, the most powerful telescope in space, suggest that the exoplanet's average temperature is about -125 degrees Fahrenheit, making it the coldest planet ever detected, according to a paper published last week in arXiv, an open archive server.
Life can grow at temperatures as low as 5 degrees Fahrenheit, scientists say. However, few organisms can complete their life cycle at temperatures below 28.4 degrees Fahrenheit.
To date, emissions from no planets cooler than about 35.33 degrees Fahrenheit -- a temperature comparable to Earth -- have been directly detected, the researchers said.
