Summary
[edit]DescriptionExoplanet Epsilon Indi Ab (MIRI image) (weic2421a).jpg |
English: This image of the gas-giant exoplanet Epsilon Indi Ab was taken with the coronagraph on the NASA/ESA/CSA James Webb Space Telescope’s MIRI (Mid-Infrared Instrument). A star symbol marks the location of the host star Epsilon Indi A, whose light has been blocked by the coronagraph, resulting in the dark circle marked with a dashed white line. Epsilon Indi Ab is one of the coldest exoplanets ever directly imaged. Light at 10.6 microns was assigned the color blue, while light at 15.5 microns was assigned the color orange. MIRI did not resolve the planet, which is a point source.[Image description: This image shows the exoplanet Epsilon Indi Ab. Blue scale-like features are visible in the background, with the host star’s light being blocked by a black circle in the centre of the image (indicated by a dashed-line and white star visual overlaid on the image). The exoplanet is visible on the left as a bright orange circle.] |

JPEG file comment | An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered a new exoplanet roughly 11 light-years from Earth. This is the first high-contrast imaging of an exoplanet to be confirmed with Webb and one of the coldest objects observed to date. The team has successfully directly imaged a new exoplanet around the star Epsilon Indi A (Eps Ind A, also known as HD209100 or HIP108870), which resides roughly 11 light-years from Earth and is around the same age as our Sun. The planet, referred to as Epsilon Indi Ab, is one of the coldest objects to be directly detected — colder than any other imaged planet and colder than all but one free-floating brown dwarf. In fact, the planet appears to be around room temperature. This provides a rare opportunity for astronomers to study the atmospheric composition of true Solar System analogues. Webb directly observed the exoplanet Epsilon Indi Ac using the Mid-InfraRed Instrument (MIRI) coronagraphic mode. This coronagraph is equipped to block the light from a distant star, while allowing the faint planet light through to reach its sensors. In this image, the star’s light is blocked by the dark circle at the centre, with the exoplanet visible as the bright object to the left.
