Disco de escombros polvoriento de Fomalhaut (imagen de Miri)

Esta imagen del polvoriento degris disco que rodea el joven fomalhauts de Webbuts de Webbuts de WebButs de Webbuts de WebButs de WebButs. Instrumento (Miri). Revela tres cinturones anidados que se extienden a 14 mil millones de millas (23 mil millones de kilómetros) de la estrella. Webb reveló los cinturones internos, que nunca antes se habían visto, por primera vez.

El telescopio espacial Hubble y el Observatorio Espacial Herschel, así como la matriz de milímetro/submilímetro de Atacama. Sin embargo, ninguno de ellos encontró ninguna estructura interior.

Estos cinturones probablemente son tallados por las fuerzas gravitacionales producidas por los planetas no vistos.

About The Image
Color Info The image is a single exposure acquired by the MIRI instrument on the James Webb Space Telescope. The color results from assigning an warm color map to a monochromatic (grayscale) image.  Orange color map: F2250W
Compass Image An orange oval extends from the 7 o’clock to 1 o’clock positions. It features a prominent outer ring, a darker gap, an intermediate ring, a narrower dark gap, and a bright inner disk. At the center is a ragged black spot where the detector is saturated.
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.
