NGC 1433 (MIRI Compass Image)

 NGC 1433 (MIRI Compass Image)

This image of the nearby galaxy NGC 1433, captured by Webb’s Mid-Infrared Instrument (MIRI) shows compass arrows, 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).

At the lower right is a scale bar labeled 7,000 light-years, 30 arcseconds. The length of the scale bar is approximately one-fifth the total width of the image. Below the image is a color key showing which MIRI filters were used to create the image and which visible-light color is assigned to each filter. From left to right, MIRI filters are: F770W is blue; F1000W and F1130W are green; and F2100W is red.

About The Data

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 wide 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: F1000W+F1130W, Red: F2100W
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.
