Scientists using the James Webb Space Telescope (JWST) have directly imaged one of the oldest and coldest-known exoplanets, Epsilon Indi Ab.
Discovery:
This is the first time JWST has imaged an exoplanet that was not previously imaged using ground-based telescopes.
Imaging Achievement:
Epsilon Indi Ab is classified as a super Jupiter with a mass more than six times that of Jupiter. It is located approximately 12 light-years from the solar system.
Exoplanet Characteristics:
The exoplanet has a surface temperature around 32 degrees Fahrenheit (0 degrees Celsius), making it much colder than other known gas giants.
Temperature:
Epsilon Indi Ab orbits about 15 times further from its star than Earth does from the Sun. Its orbital period is thought to span several decades, similar to Neptune in our solar
Orbital Distance:
JWST used its MIRI (Mid-Infrared Instrument) to capture the images. MIRI is sensitive to infrared light and equipped with a coronagraph to block out the star s light
Imaging Technology:
Although Epsilon Indi Ab is rare, it is not the closest known super Jupiter to the solar system. The closest one is Epsilon Eridani b, located 10.5 light-years away.
Astronomical Context:
The researchers aim to measure the light reflected off Epsilon Indi Ab to analyze its atmospheric composition and climate. They also plan to survey other nearby planetary systems
