Epsilon Indi Ab Exoplanet (MIRI Image)

Epsilon Indi Ab Exoplanet (MIRI Image)

This image of the gas-giant exoplanet Epsilon Indi Ab was taken with the coronagraph on NASA’s 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.

About The Data
Data Description This image was created with Webb data from proposal: (E. Matthews)
Instrument MIRI
Exposure Dates 03 July 2023
Filters F1065C; F1550C
About The Image
Color Info These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument with a coronagraph. Two filters were used to sample wide wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:  Cyan: F1065C Orange: F1550C
About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
