Aspire Cosmic Filament (imagen de Nircam)

Este campo de galaxia profunda del Nircam de Webb (cámara de infrarrojo cercano) muestra una disposición de 10 galaxias distantes marcadas por ocho círculos blancos en una línea diagonal de rosca. (Dos de los círculos contienen más de una galaxia). Este filamento de 3 millones de años luz está anclado por un cuásar muy distante y luminoso, una galaxia con un agujero negro activo y supermasivo en su núcleo. El cuásar, llamado J0305-3150, aparece en el medio del grupo de tres círculos en el lado derecho de la imagen. Su brillo eclipsa su galaxia anfitriona. Las 10 galaxias marcadas existieron solo 830 millones de años después del Big Bang. El equipo cree que el filamento eventualmente se convertirá en un grupo masivo de galaxias.

About The Data
Data Description This image was created with Webb data from proposal: (F. Wang)
Instrument NIRCam
Exposure Dates August 2022
Filters F115W, F200W, F356W
About The Image
Color Info These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several 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:   Blue: F115W Green: F200W Red: F356W
Compass Image Image shows a black field speckled with a variety of galaxies of numerous shapes and sizes. The galaxies are white, yellow, blue and red. Red is the predominant galaxy color in the field, indicating very distant galaxies. Eight white circles mark the position of 10 galaxies (two circles contain more than one galaxy). The 10 galaxies are arranged in a diagonal, thread-like line from the bottom left to the top right. This 3-million-light-year-long filament is anchored by a very distant and luminous quasar – a galaxy with an active, supermassive black hole at its core. The quasar, called J0305-3150, appears in the middle of the cluster of three circles on the right side of the image. Its brightness outshines its host galaxy.
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.
