A new study has found that the exoplanet WASP-76b, which scientists initially thought had a surface temperature of 4,400 degrees Fahrenheit, is actually warmer than previously thought.
A team of researchers led by Cornell University also observed the discovery of ionized calcium in the planet’s atmosphere, which indicates higher temperatures than expected.
The researchers did not speculate on the exact temperature of the planet, but note that their findings came from looking at the planet with a high-resolution spectrum from the Gemini North telescope near Mount Mauna Kea in Hawaii.
Emily Debert, lead author of the study, said in a statement: Report: “We see a lot of calcium. This is a very powerful feature. This spectral signature of ionized calcium may indicate that there is a very strong wind in the upper atmosphere of an atmosphere. Or the temperature of the atmosphere on an extraterrestrial is much higher than we thought.”
During the day, the WASP-76b (discovered in 2016) is warmer than previously thought, at 4,400 degrees Fahrenheit, but the night side is considerably cooler.
The parent star, WASP-76, is about one and a half times the size of the Sun and has a surface temperature of about 10,000 degrees Fahrenheit.
Evaporated iron moves with more wind from day to night, some of which were seen above 11,184 miles per hour.
At night, the iron particles cool and the iron droplets fall like “rain” on this part of the planet.
About 640 light-years from Earth, the planet is considered to be a gas giant orbiting its host star, WASP-76.
When it was first discovered, researchers found that it rained iron and that wind speeds were approaching 11,000 miles per hour.
Although researchers have not provided an updated temperature, the Milky Way is a unique place that belongs to all kinds of planets.
The study was published in the journal. Letters in Astronomical Physics.
