Una parte de la Galaxy Wolf-Lundmark-Melotte (WLM) enano capturada por la cámara de matriz infrarroja del telescopio espacial Spitzer (izquierda) y la cámara de infrarrojo cercano del telescopio espacial James Webb (derecha). Las imágenes demuestran la notable capacidad de Webb para resolver estrellas débiles fuera de la Vía Láctea. La imagen Spitzer muestra una luz de 3,6 micras en cian y 4.5 micrones en naranja. (IRAC1 e IRAC2). La imagen Webb incluye luz de 0.9 micras que se muestra en azul, 1.5 micrones en cian, 2.5 micras en amarillo y 4.3 micrones en rojo (filtros F090W, F150W, F250M y F430M).

| About The Data | |
| Data Description | The Webb image was created from JWST data from proposal: (D. Weisz) |
| Instrument | Spitzer>IRAC Webb>NIRCam |
| Exposure Dates | Spitzer: 5 Feb 2010 Webb: 23-24 July 2022 |
| Filters | Spitzer: IRAC 3.6µm, IRAC 4.5µm Webb: F090W, F150W, F250M, F430M |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the Spitzer Space Telescope and the James Webb Space Telescope using the IRAC and NIRCam instruments respectively. Several filters were used to sample different infrared 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: Spitzer> Cyan: IRAC 3.6um, Orange: IRAC 4.5um Webb> Blue: F090W, Cyan: F150W, Yellow: F250M, Red: F430M |
| 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. |
