Hubble Ultra Deep Field 

 Hubble Ultra Deep Field 

This Hubble Space Telescope image, known as the Hubble Ultra Deep Field, reveals about 10,000 galaxies and combines ultraviolet, visible, and near-infrared light. Two programs that will use the James Webb Space Telescope will add more detail to this image, capturing thousands of additional galaxies in a fuller range of infrared light. Webb will return both imagery and data known as spectra, providing more details about some of the earliest galaxies to exist in the universe for the first time.

This image was captured before the launch of the James Webb Space Telescope. No Webb data are shown in this 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.
