Los investigadores que utilizan el NIRCAM del telescopio espacial James Webb de la NASA (cámara de infrarrojo cercano) han descubierto una corriente de chorro de alta velocidad que se encuentra sobre el ecuador de Júpiter, por encima de las cubiertas principales de la nube. Con una longitud de onda de 2.12 micras, que observa entre altitudes de aproximadamente 12-21 millas (20-35 kilómetros) por encima de la cima de las nubes de Júpiter, los investigadores vieron varias cizallas de viento, o áreas donde las velocidades del viento cambian con la altura o la distancia, lo que les permitió rastrear el avión. Esta imagen resalta varias de las características alrededor de la zona ecuatorial de Júpiter que, entre una rotación del planeta (10 horas), están muy claramente alteradas por el movimiento de la transmisión de chorro.

| About The Object | |
|---|---|
| Object Name | Jupiter |
| Object Description | Planet |
| Distance | On July 27th, 2022 Jupiter was 4.44 AU from Earth (about 413 million miles). |
| About The Data | |
| Data Description | This image was created with Webb data from proposal: 1373 (I. de Pater). Image Processing: Joseph DePasquale (STScI) |
| Instrument | NIRCam |
| Exposure Dates | 27 July 2022 |
| Filters | F164N, F212N, F360M |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Three filters were used to sample narrow 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: F360M, Green: F212N, Blue: F164N |
| 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. |
