L1527 and Protostar (MIRI Compass Image)

 L1527 and Protostar (MIRI Compass Image)

This image of the nebula L1527, captured by Webb’s Mid-Infrared Instrument (MIRI), shows compass arrows, a scale bar, and color key for reference.

The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).

The scale bar is labeled in astronomical units (AU), which is the average distance between Earth and the Sun, or 93 million miles (150 million kilometers). 

This image shows invisible mid-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which MIRI filters were used when collecting the light. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter.

About The Data
Data Description This image was created from JWST data from proposal: 2739 (K. Pontoppidan)

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.
