Jets Carina Nebula (filtros de banda estrecha nircam)

Docenas de aviones y salidas previamente ocultas de estrellas jóvenes se revelan en esta nueva imagen de los acantilados cósmicos de la cámara de infrarrojo cercano de James Webb Space Telescope de la NASA (NIRCAM). Los acantilados cósmicos, una región en el borde de una cavidad gigantesca y gaseosa dentro de NGC 3324, ha intrigado durante mucho tiempo astrónomos como un semillero para la formación de estrellas.

Muchos detalles de la formación de estrellas en NGC 3324 permanecen ocultos en longitudes de onda de luz visible. Webb está perfectamente preparado para descubrir estos detalles más buscados, ya que puede detectar aviones y salidas vistas solo en el infrarrojo a alta resolución.

Esta imagen separa varias longitudes de onda de luz de la icónica Primera imagen revelada el 12 de julio de 2022 que resalta el hidrógeno molecular, un ingrediente vital para la formación de estrellas. Las inserciones en el lado derecho destacan tres regiones de los acantilados cósmicos con salida de hidrógeno molecular particularmente activo.

En esta imagen, se asignaron a los datos NIRCAM de Webb a 4.7, 4.44 y 1.87 microns (F470N, F4444W y F187N FILTRES, respectivamente).

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 F187N, 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: F470N, Green: F444W, Blue: F187N
Compass Image The image is split into four boxes. The large box on the left-hand side of the image takes up half of the entire image, then the 3 boxes on the right (two boxes split vertically at the top, the third across the bottom) are pull-outs from labeled 1, 2, and 3 respectively. The large image at the left 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. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. The 3 pull-out images are close-ups in on bright red splotches within the loud, labeled as fiery molecular hydrogen outflows and jet and bow shocks.
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.
