L1527, que se muestra en esta imagen del Miri del telescopio espacial James Webb (instrumento de infrarrojo) de la NASA, es una nube molecular que alberga una protástica. Reside alrededor de 460 años luz de la Tierra en la constelación de Tauro. La luz azul más difusa y las estructuras filamentosas en la imagen provienen de compuestos orgánicos conocidos como hidrocarburos aromáticos policíclicos (HAP), mientras que el rojo en el centro de esta imagen es una capa energizada y gruesa de gases y polvo que rodea el Protostar. La región intermedia, que aparece en blanco, es una mezcla de HAP, gas ionizado y otras moléculas.
Esta imagen incluye filtros que representan 7.7 micras de luz como azul, luz de 12.8 micras como verde y 18 micras como rojo.

| Instrument | MIRI |
| Exposure Dates | 08 Sep 2022 |
| Filters | F770W, F1280W, F1800W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. 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: Blue: F770W, Green: F1280W, Red: F1800W |

| 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. |
