"Cliffs cósmicos" en Carina Nebula (imagen de Nircam)

Lo que se parece mucho a las montañas escarpadas en una noche iluminada por la luna es en realidad el borde de una región cercana, joven formadora de estrellas NGC 3324 en la Nebulosa Carina. Capturado en luz infrarroja por la cámara de infrarrojo cercano ( nircam ) en el nasa webbop Nacimiento.

llamado acantilados cósmicos, la región es en realidad el borde de una cavidad gigantesca y gaseosa dentro de NGC 3324, aproximadamente a 7,600 años luz de distancia. El área cavernosa ha sido tallada en la nebulosa por la intensa radiación ultravioleta y los vientos estelares de estrellas jóvenes extremadamente masivas, calientes y ubicadas en el centro de la burbuja, sobre el área que se muestra en esta imagen. La radiación de alta energía de estas estrellas está esculpiendo la pared de la nebulosa al erosionarlo lentamente.  

nircam, con su resolución nítida y su sensibilidad incomparable, revela cientos de estrellas previamente ocultas e incluso numerosas galaxias de fondo. A continuación se describen varias características prominentes en esta imagen.

: el "vapor" que parece surgir de la "montañas" celestial es en realidad gas caliente, ionizado y polvo caliente que se aleja de la nebulosa debido a la intensa radiación ultravioleta. 

-Los pilares dramáticos se elevan por encima de la pared brillante de gas, que se resisten a la ampolladora radiación ultravioleta de las estrellas jóvenes.

-burbujas y cavidades están siendo volados por la radiación intensa y los vientos estelares de las estrellas recién nacidas.

-Jets de prototellares y emergentes, que aparecen en el oro, se disparan desde el dorado, las estrellas recién nacidas.

-Un "reventón" estalla en el centro superior de la cresta, arrojando gas y polvo en el medio interestelar. 

-Aparece un "arco" inusual, que parece un cilindro doblado.

Este período de muy temprano Formación estrella Es difícil capturar porque, por una estrella individual, solo se ha ido a los 100 años. Pero la sensibilidad extrema de Webb y la exquisita resolución espacial han relatado este raro evento.

ubicado aproximadamente a 7,600 años luz de distancia, NGC 3324 fue catalogado por primera vez por James Dunlop en 1826. Visible desde la hemismos del sur, se encuentra en la esquina noroeste de la nebulosa Carina (NGC 3372). La Nebula Carina es el hogar de la nebulosa del ojo de la cerradura y la estrella supergigante activa e inestable llamada Eta Carinae. 

nircam fue construido por un equipo en el Centro de Tecnología Avanzada de la Universidad de Arizona y Lockheed Martin.

About The Data
Data Description This image was created with Webb data from proposal . It is part of Webb Early Release Observations. The Early Release Observations and associated materials were developed, executed, and compiled by the ERO production team: Jaclyn Barrientes, Claire Blome, Hannah Braun, Matthew Brown, Margaret Carruthers, Dan Coe, Joseph DePasquale, Nestor Espinoza, Macarena Garcia Marin, Karl Gordon, Alaina Henry, Leah Hustak, Andi James, Ann Jenkins, Anton Koekemoer, Stephanie LaMassa, David Law, Alexandra Lockwood, Amaya Moro-Martin, Susan Mullally, Alyssa Pagan, Dani Player, Klaus Pontoppidan, Charles Proffitt, Christine Pulliam, Leah Ramsay, Swara Ravindranath, Neill Reid, Massimo Robberto, Elena Sabbi, Leonardo Ubeda.  The EROs were also made possible by the foundational efforts and support from the JWST instruments, STScI planning and scheduling, Data Management teams, and Office of Public Outreach.
Instrument NIRCam
Exposure Dates 3 June 2022
Filters F090W, F187N, F200W, F335M, F444W, F470N
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 narrow and broad 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:   Red: F444W, Orange: F335M, Yellow: F470N, Green: F200W, Cyan: F187N, Blue: F090W
Compass Image The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which, have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
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.
