Hubble Legacy Field Relative Size on the Sky

Comparison of Hubble Legacy Field with Full Moon

This graphic compares the dimensions of the Hubble Legacy Field on the sky with the angular size of the Moon.

The Hubble Legacy Field is one of the widest views ever taken of the universe with Hubble. The new portrait, a mosaic of nearly 7,500 exposures, covers almost the width of the full Moon. The Moon and the Legacy Field each subtend about an angle of one-half a degree on the sky (or half the width of your forefinger held at arm's length).

Astronomers assembled the image from 16 years' worth of Hubble observations. The image combines several Hubble deep-field surveys. The wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time.
