L1527 and Protostar (MIRI Image)

L1527, shown in this image from NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument), is a molecular cloud that harbors a protostar. It resides about 460 light-years from Earth in the constellation Taurus. The more diffuse blue light and the filamentary structures in the image come from organic compounds known as polycyclic aromatic hydrocarbons (PAHs), while the red at the center of this image is an energized, thick layer of gases and dust that surrounds the protostar. The region in between, which shows up in white, is a mixture of PAHs, ionized gas, and other molecules.

This image includes filters representing 7.7 microns light as blue, 12.8 microns light as green, and 18 microns light as red.

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
Compass Image A growing protostar embedded within a molecular cloud. The center of the image shows a bright, red region, where the protostar resides, with a thin, gray lane cutting through it horizontally, which is the protostar’s accretion disk. Above and below this region are white and blue triangular-shaped cavities in the molecular cloud, which give the overall object an hourglass shape. The areas of the cavities closest to the central protostar have more pronounced plumes of white gas and dust that fade to a blue color further from the center. There are red, yellow, orange, blue, and green stars and galaxies scattered across the image.
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.
