I'm sure all of us can agree that most, if not all, images taken of the universe are stunning. Some images, however, are not only stunning, they also offer us a new perspective on the universe and ourselves. One such image is the Hubble Deep Field. In 1995, astronomers performed an experiment in which they pointed the Hubble telescopes gaze at what appeared to be an empty region of the sky located in the constellation of Ursa Major for a total of ten days. With no bright stars or galaxies in the way, Hubble's sensitive instruments were able to capture light from some of the most distant objects in the cosmos over a total of 342 separate exposures. What astronomers found in Hubble's images was absolutely astonishing. What appeared to be an empty and dark region of the cosmos turned out to be filled with some of the most distant galaxies. The image was called the Hubble Deep Field. The image itself covers a region in the sky just 1/24th of a degree across, which is an extremely tiny region in the sky, yet there are over 3,000 individual galaxies in the image, some containing as many as 100 billion stars. Some of these galaxies are the oldest and farthest objects known, the earliest of which formed less than a billion years after the big bang. To date, the Hubble Deep Field is considered to be one of Hubble's most iconic images ever taken. Some of these galaxies formed long before the sun and the solar system were born. When you view this image you're looking billions of years into the past, long before there was any humans, life, and even Earth.
