Tarantula Nebula (imagen de Nircam)

Tarantula Nebula (imagen de Nircam)

En esta imagen de mosaico que se extiende 340 años luz de luz, la cámara de infrarrojo cercano de Webb (NIRCAM) muestra la región formadora de estrellas de la nebulosa Tarantula en una nueva luz, incluidas decenas de miles de estrellas jóvenes nunca vistas que anteriormente estaban envueltas en polvo cósmico. La región más activa parece brillar con estrellas jóvenes masivas, que aparecen azul pálido. Entre ellas dispersas entre ellas, todavía son estrellas incrustadas, que aparecen en rojo, aún para emerger del polvoriento capullo de la nebulosa. Nircam puede detectar estas estrellas envueltas en polvo gracias a su resolución sin precedentes en longitudes de onda de infrarrojo cercano. 

A la parte superior izquierda del grupo de estrellas jóvenes, y la parte superior de la cavidad de la nebulosa, una estrella más antigua muestra prominentemente los ocho distintivos de Nircam , un artefacto de la estructura del telescopio. Siguiendo el pico central superior de esta estrella hacia arriba, casi apunta a una burbuja distintiva en la nube. Las estrellas jóvenes todavía rodeadas de material polvoriento están soplando esta burbuja, comenzando a forjar su propia cavidad. Los astrónomos utilizaron dos de los espectrógrafos de Webb para observar más de cerca esta región y determinar la composición química de la estrella y su gas circundante. Esta información espectral les dirá a los astrónomos sobre la edad de la nebulosa y cuántas generaciones de parto de estrellas ha visto. 

Más allá de la región central de las estrellas jóvenes calientes, el gas más frío adquiere un color de óxido, diciéndole a los astrónomos que la nebulosa es rica en hidrocarburos complejos. Este denso gas es el material que formará futuras estrellas. A medida que los vientos de las enormes estrellas barren el gas y el polvo, algunos de ellos se acumularán y, con la ayuda de Gravity, forman nuevas estrellas. 

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 from JWST 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 2 June 2022
Filters F090W, F200W, F335M, F444W
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 different infraraed 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 Green: F200W Blue: F090W
Compass Image Tan-colored nebula clouds with rust-colored highlights, surrounding a black central area containing a bright cluster of sparkling pale blue stars that scatter outward from a densely packed center. One bright yellow star stands out in the central open area, with eight long thin points.
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.
