NGC 1433 (imagen de Miri)

Esta imagen tomada por el telescopio espacial James Webb de la NASA muestra una de un total de 19 galaxias dirigidas a estudiar la física a alta resolución angular en la colaboración de galaxias cercanas (PHANGS). El cercano Galaxy Spiral Galaxy NGC 1433 adquiere un aspecto completamente nuevo cuando se observa por el instrumento de infrarrojo medio (MIRI) de Webb. 

Los brazos espirales de NGC 1433 están llenos de evidencia de estrellas extremadamente jóvenes que liberan energía y, en algunos casos, soplan el gas y el polvo del medio interestelar. Las áreas que parecen oscuras y tenue en las imágenes ópticas se iluminan bajo el ojo infrarrojo de Webb. Esto se debe a grupos de polvo y gas en el medio interestelar que absorbe la luz de la formación de estrellas y la emitirá de nuevo en el infrarrojo.

La imagen de Webb de NGC 1433 es una fuerte visualización de cómo los procesos dinámicos asociados con las estrellas de la forma más grande de una galaxia completa. con la resolución extrema de Webb. En este caso, ese "anillo doble" es en realidad los brazos espirales muy envueltos que se enrolan en una forma ovalada a lo largo de la barra de la galaxia.

ngc 1433 es una galaxia Seyfert, que generalmente está relativamente cerca de la Tierra y tiene un agujero negro supermasivo a un material de alimentación central a una velocidad alta. El brillo y la falta de polvo en la imagen de Miri de NGC 1433 podrían insinuar una colisión reciente con otra galaxia.

NGC 1433 se encuentra a más de 46 millones de años luz de la Tierra en la Tierra en el horológico de la constelación. Consorcio) y el Laboratorio de Propulsión de Jet de la NASA, en asociación con la Universidad de Arizona.

About The Data
Data Description This image was created with Webb data from proposal: (J. Lee).
Instrument MIRI
Exposure Dates 19 Jan 2023
Filters F770W, F1000W, F1130, F2100W
About The Image
Color Info These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI 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: F770W, Green: F1000W+F1130W, Red: F2100W
Compass Image A large galaxy takes up the entirety of the image. The image is mostly black with a bright, glowing oval core at the center. The core is mostly bright white, but there are also swirling, detailed structures that resemble water circling a drain. There is white and light blue colored dust that emanates from the core’s center, but it is tightly contained to the core. There is black space between the core and glowing dust of the outer oval rings. The rings are wispy and highlight filaments of dust around cavernous black bubbles. The dust in the outer rings contains dots that are navy blue, pinkish, reddish, and white. Throughout, there is also a smattering of background galaxies seen as small red and greenish dots.
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.
