Encuesta Transient Jades (imagen de Nircam)

El campo profundo de Jades utiliza observaciones tomadas por el Telescopio Space James Webb de la NASA (JWST) como parte del programa Jades (JWST Advanced Deep Extragalactic Survey). Un equipo de astrónomos que estudian datos de Jades identificados sobre 80 objetos (en rodajas en verde) que cambiaron en brillo con el tiempo. La mayoría de estos objetos, conocidos como transitorios, son el resultado de explosiones de estrellas o supernovas.

Antes de esta encuesta, solo se habían encontrado un puñado de supernovas arriba a < href = "https://webbtelescope.org/glossary.html#h3-ck-a138baf3-5963-4640-a405-aa3552a5152e"> Redshift de 2, que corresponde a cuando el universo tenía solo 3.300 millones de años, solo el 25% de su edad actual. La muestra de Jades contiene muchas supernovas que explotaron aún más en el pasado, cuando el universo tenía menos de 2 mil millones de años. Incluye el más lejano Spectroscópicamente confirmado, en un desplazamiento de 3.6. Su estrella progenitora explotó cuando el universo tenía solo 1.800 millones de años.

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: F090W + F115W + F150W Green: F200W + F277W + F335M Red: F356W + F410M + F444W
Compass Image Space telescope image showing hundreds of objects of different colors, shapes, and sizes scattered across the black background of space. There are small red blobs; larger, fuzzy white or blueish ball-shaped masses with bright centers; white, pink, or blue disc shapes; clear spiral structures; and barely discernible specs. Eighty-three of the smaller objects in the image are circled in green. Some of the circles are close together; some are far apart; some overlap. There is no apparent pattern in the distribution.
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.
