Hubble Ultra Deep Field (HUDF) The HUDF is the deepest visible-light image of the universe ever observed by a telescope. The image shows about 10,000 galaxies, some as far as 13 billion light-years away The patch of sky is just one-tenth the area of the full Moon as seen from Earth..

b. Angular size : Diameter/Distance e. Colliding galaxies: not only close to each other, but also appear to be disrupted f. Colors: red, yellow, white, blue h. Lab 9, question e. i. Area of the Planetary Camera: 35 arcsecond x 35 arcseconds= ? degree x ? Degree=? Square degree
