  4. Webb Telescope Observes Extreme Heat on Exoplanet HD 80606 b

    NASA's James Webb Space Telescope captured the first mid-infrared spectroscopic observations of the gas giant HD 80606 b. The planet follows an extremely elliptical orbit around a Sun-like star, causing massive temperature fluctuations. Researchers are using these conditions to test theories on atmospheric chemistry, dynamics, and radiation.

    What's confirmed:

    • Exoplanet HD 80606 b is a gas giant approximately four times the mass of Jupiter.
    • The planet has an extremely elliptical orbit around a Sun-like star.
    • HD 80606 b experiences temperature swings of 1,100 degrees Fahrenheit (600 degrees Celsius) during its 111-day orbit.
    • The James Webb Space Telescope captured the first mid-infrared spectroscopic observations of the planet before, during, and after its closest approach to the star.
    • Research findings are being presented at the 248th meeting of the American Astronomical Society in Pasadena, California.

    Still unconfirmed:

    • The planet heats up by 610°C when approaching its star.
    confidence 100%
