Neptune Wide Field (NIRCam)

 Neptune Wide Field (NIRCam)

In this image by Webb’s Near-Infrared Camera (NIRCam), a smattering of hundreds of background galaxies, varying in size and shape, appear alongside the Neptune system.

Neptune, when compared to Earth, is a big planet. If Earth were the size of a nickel, Neptune would be as big as a basketball. In most portraits, the outer planets of our solar system reflect this otherworldly size. However, Neptune appears relatively small in a wide-field view of the vast universe.

Towards the bottom left of this image, a barred spiral galaxy comes into focus. Scientists say this particular galaxy, previously unexplored in detail, may be about a billion light-years away. Spiral galaxies like this are typically dominated by young stars that appear blueish in these wavelengths.

NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.

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

Filters F140M, F210M, F300M, F460M
About The Image
Color Info These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample different infraraed 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: F460M Orange: F300M Green: F210M Blue: F140M
Compass Image Image titled “Neptune Wide Field (NIRCam).” Hundreds of small galaxies appear around the field of view, and just a little off-center is a glowing sphere. At 11 o’clock to the glowing sphere, there is a very bright point of light with eight diffraction spikes. The colors of the galaxies that splatter across the image vary. Some are shades of orange, others are white. Most appear as fuzzy white ovals. The bright stars have diffraction spikes, forming an eight-pointed star shape. At the bottom left of the image, there is a very small barred spiral galaxy, which glows light blue.
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.
