My simple blog of pictures of travel, friends, activities and the Universe we live in as we go slowly around the Sun.

Hubble Ultra Deep Field
http://www.youtube.com/watch?feature=player_embedded&v=PDMp8a-YNe0
What would it look like to fly through the distant universe? To find out, a team
of astronomers estimated the relative distances to over 5,000 galaxies in one of
the most distant fields of galaxies ever imaged: the Hubble Ultra Deep Field (HUDF). Because
it takes light a long time to cross the universe, most galaxies visible in the
above video are seen
when the universe was only a fraction of its current age, were still
forming, and have unusual shapes when compared to modern galaxies. No mature
looking spiral galaxies such as our Milky Way or the
Andromeda galaxy yet exist. Toward the end of the
video the virtual observer flies past the furthest
galaxies in the HUDF field, recorded to have a redshift past 8. This early class of low luminosity galaxies
likely contained energetic stars emitting light that
transformed
much of the remaining normal matter in the universe
from a cold gas to a hot ionized plasma.
