With a mass several times that of Jupiter, the planet is around the age of the Sun, but slightly cooler. K-type star Epsilon Indi AIt orbits around . The team brought Epsilon Indi Ab to JWST. MIRI on (Mid Infrared Instrument) coronagraph Observed using . Previously, only a few exoplanets had been directly imaged by space- and ground-based observatories.
Its temperature is only 2 degrees
Scientists say this discovery is exciting because the planet pretty much Jupiter looks like, just a little warmer and bigger. Previously imaged exoplanets tend to be young, hot planets that still emit much of the same energy as when they first formed. Because planets get colder and dimmer as they age. This makes them difficult to view.
Epsilon Indi Ab is the twelfth closest exoplanet to Earth known to date and the closest planet larger than Jupiter. However, it is also stated that the planet does not match what was previously predicted. It is stated that the planet is twice as large as expected and travels in a different orbit. The planet’s atmosphere also looks slightly different from model predictions. Scientists do not yet know the reason for these inconsistencies.
Scientists plan to make follow-up observations with JWST. NASA’s upcoming Nancy Grace Roman Space Telescope, on the other hand, will use a coronagraph that can directly image Jupiter-like planets orbiting Sun-like stars. With Nancy Grace Roman, the missing areas of JWST will be filled.
