Hubble gazes at distant history

So, it only takes 450 million years for galaxies to form? Click on HUBBLE.

Its instruments trained for six weeks on a relatively uninteresting patch of sky, Hubble spotted the galaxies swirling at a time 13.3 billion years ago, just 450 million years after the dawn of the cosmos.

And astrophysicists say the images give the world an unprecedented look at the universe in the early stages of its formation.

“It’s the scientific version of the story of Genesis, basically,” said Abraham Loeb, Chair of the Astronomy Department at Harvard University in Cambridge, Mass.

“This is the beginning of everything,” added John Grunsfeld, Associate Administrator for NASA’s Science Mission Directorate and a former astronaut who serviced Hubble on three shuttle missions.

“And these images are starting to give us the picture of what emerges from that early period in the universe.”

The results show an evenly paced decline in the number of galaxies evident in observations that look back over 97 percent of time dating back to the birth of the universe 13.7 billion years ago. They support the idea that galaxies formed continuously over time and also might have provided enough radiation to reheat matter after a period when all matter cooled in the wake of the Big Bang. “You know, this period of re-ionization is when the universe emerged from the ‘dark ages,’ as it’s called, when light couldn’t propagate through the universe.

Those were the days my friend

we thought they'd never end.....

By the way, there IS a before...

We just don't know what it is.
