New Stunning Hubble Ultra Deep Field Image released

This is yet another astonishing image from Hubble. This is a new version of the Ultra Deep Field, in near-infrared light and taken with the newly installed Wide Field Camera 3. This image is of the same region as the visible Ultra Deep Field in 2004, but at longer wavelengths providing more information about the early Universe’s history. We are starting to see the earliest galaxies, 600 Million years after the big bang.

Click on the image and see the larger image. Or better yet click here for a zoomable version. The sheer number of galaxies is incredible….It will blow you away. The faintest objects visible now are about one billion times fainter than the dimmest visible objects seen with the naked eye. Its truely astronomical!

“Hubble has now re-visited the Ultra Deep Field which we first studied 5 years ago, taking infrared images which are more sensitive than anything obtained before,” said Dr. Daniel Stark, a postdoctoral researcher from Cambridge University. “We can now look even further back in time, identifying galaxies when the Universe was only 5 percent of its current age – within 1 billion years of the Big Bang.”

“The expansion of the Universe causes the light from very distant galaxies to appear more red, so having a new camera on Hubble which is very sensitive in the infrared means we can identify galaxies at much greater distances than previously possible,” said Stephen Wilkins, from Oxford University.

Want to know where in the sky this image is taken from? Look below. In the centre of the image is the HDUF cross-hair. That the “empty” piece of sky….

    Number of observable stars in the universe: 70,000,000,000,000,000,000,000 (7*
    10^22)
    Number of people on earth: 6,500,000,000 (6.5 billion)

    Number of observable stars per person on earth: 10,000,000,000,000 (10 trillion)

    Theres a lot of material out there. There’s also very few of us.
