Farthest Objects Ever Seen Pinpointed in the Hubble Ultra Deep Field

Detailed analyses of mankind's deepest optical view of the universe, the Hubble Ultra Deep Field (HUDF), by several expert teams have at last identified what may turn out to be some of the earliest star-forming galaxies. The sensitivity of Hubble's Advanced Camera for Surveys...

Hubble Ultra Deep Field 3-D Fly-Thru

A flight through the Hubble Ultra Deep Field, the most distant visible-light view of the universe. The redshifts of 5,333 galaxies were converted to distances to assemble a 3-D model of the data. This scientific visualization flies through the data to showcase its true 3-D...

HUDF: 108 High-Redshift Galaxy Candidates Identified

One hundred and eight extremely distant, small and red galaxies were identified within the Hubble Ultra Deep Field. After the reveal of the locations of all 108 galaxies, it then zooms into a close-up of three representative candidates.

HUDF Zoom

This "zoom" starts in the Fornax constellation and pushes through deeper and narrower telescopic fields to at last reach Hubble's Ultra Deep Field, where astronomers have identified 108 very distant galaxies. The zoom reveals the locations of the 108 galaxies, then it pushes...

3-D Illustration: Cosmological Reionization Process

"The end of the dark ages": A 3-D illustration of the "Cosmological Re-ionization" process, which occurred shortly after the birth of the universe. The first stars formed and were able to re-heat hydrogen gas, turning it into transparent plasma. The first stars, grouped in...
