The Hubble Ultra Deep Field is one of the most beautiful examples of the sheer magnitude of our universe. Today, astronomers released the latest ultraviolet data to complement the existing images made at near-infrared through visible light wavelengths.
There are countless galaxies within the image -- well, about 10000, actually. But this small snapshot corresponds to only a tiny fraction of the total area of the sky -- one thirteen-millionth, actually. So times the number of galaxies you can see in this by thirteen million, and you're beginning to get a glimpse as to how stupedously big the observable universe is. Our own galaxy has about 300 billion stars by itself!
Astronomers using the Hubble Space Telescope have captured the most comprehensive picture ever assembled of the evolving Universe — and one of the most colourful. The study is called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF) project.
