The observation, called the Ultraviolet Coverage of the Hubble Ultra Deep Field, provides the missing link in star formation. In 2014, astronomers released the most colorful and comprehensive picture of the evolving universe ever captured by Hubble. Surveys like the Hubble Ultra Deep Field (HUDF), and the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) have provided pictures of vast, deep collections of galaxies - including some that existed when the universe was less than a billion years old. In subsequent years, Hubble teamed with other observatories to examine small patches of the sky in high resolution with long exposures and multiple wavelengths. Illingworth (University of California, Santa Cruz) News Release: 2006-12 > This image, called the Hubble Ultra Deep Field, shows 28 of the more than 500 young galaxies that existed when the universe was less than 1 billion years old. With the Hubble Deep Field, we reach back nearly to the time when galaxies emerged from the chaos of the big bang. We can see how they changed through time. The galaxies vary in shape, size and color. There are a few foreground stars, many remote galaxies and more galaxies in between. The results are a treasure trove: 3,000 galaxies, large and small, shapely and amorphous, burning in the depths of space. This is really a three-dimensional picture, a cosmic core sample. It showed us a sliver of the early universe, from long before our sun was born. The light from some of these has traveled for 10 billion years to reach us. What emerged - the Hubble Deep Field - revealed galaxies fainter than had ever been seen before. The telescope gathered all the light it could, slowly building a picture. We see those objects not as they are today, but as they appeared long ago.įor 10 straight days in 1995, Hubble stared at a tiny and nearly empty patch of sky near the Big Dipper. The light arriving at our location from the farthest objects in the universe is light that left those objects billions of years ago. When we look out at space, we are looking back in time.
