El telescopio espacial James Webb de la NASA ha fotografiado al sistema estelar beta pictoris. Miri (instrumento de infrarrojo medio) de Webb permitió a un equipo de astrónomos investigar la composición de los discos de escombros principales y secundarios de Beta PIC: la última característica detectada anteriormente por el telescopio espacial Hubble.
inesperadamente, las capacidades infrarrojas de Webb detectaron una característica de la nueva característica del sistema Beta PIC: una rama curval de polvo que resurra la forma de la forma de la forma de Cat. Esta cola, solo notable en los datos de MIRI, se extiende desde la porción suroeste del disco de escombros secundarios y se estima que abarca 10 mil millones de millas.
El polvo que forma la cola puede ser similar a la materia que se encuentra en las superficies de cometas y asteroides en nuestro sistema solar. Se requiere un análisis adicional para comprender los orígenes de la cola del gato, aunque el equipo cree que un evento de producción de polvo, como una colisión entre asteroides, cometas o planetesimales, es responsable.
Un coronagraph (círculo negro y dos discos pequeños) se ha utilizado para bloquear la luz de la estrella central, cuya ubicación está marcada con una forma de estrella blanca. En esta imagen, la luz a 15.5 micras es de color cian y 23 micras es naranja (filtros F1550C y F2300C, respectivamente).

| About The Data | |
| Data Description | This image was created with Hubble data from proposal: (C. Stark). Image Processing: Alyssa Pagan (STScI). |
| Instrument | MIRI |
| Exposure Dates | 13 December 2022 |
| Filters | F1550C, F2300C |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. Several filters were used to sample specfic 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: Cyan: F1550C Orange: F2300C |

| 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. |
