What emerged — the Hubble Deep Field — revealed galaxies fainter than had ever been seen before. The light from some of these has traveled for 10 billion years to reach us. It showed us a sliver of the early universe, from long before our sun was born. This is really a three-dimensional picture, a cosmic core sample.Jun 2, 2019

What have we learned from the Hubble Extreme Deep Field?
The Hubble Ultra Deep Field It reveals some of the first galaxies to emerge from the "dark ages", the time shortly after the Big Bang when the first stars reheated the cold, dim universe. The Ultra Deep Fields show the furthest away galaxies that can be observed in visible light.
Why was the Hubble Deep Field such an important discovery?
Scientific results One of the most fundamental findings was the discovery of large numbers of galaxies with high redshift values. As the Universe expands, more distant objects recede from the Earth faster, in what is called the Hubble Flow.
What is the importance of the Hubble Extreme Deep Field image?
It was the deepest portrait of the universe ever taken at the time. The snapshot, dubbed the Hubble Deep Field, contained thousands of nearby and distant galaxies. The image represents only a tiny sample of the universe, but it was important because it gave scientists the first look at galaxies when they were young.
What does the Hubble Deep Field image show us?
The Hubble Deep Field image holds 342 separate exposures taken between December 18 and 28, 1995. The picture we see was assembled from blue, red, and infrared light. The combination of these images allows astronomers to infer the distance, age, and composition of the galaxies photographed.
Why is the Hubble telescope important?
The Hubble Space Telescope was launched in 1990, taken to space in the cargo bay of the space shuttle Discovery. Its main purpose was to figure out a distance scale of the Universe (how big it is) and where the elements present in space came from.
Is space actually colorful?
Galaxies are not actually as colorful as we think they are Space emits a range of wavelengths of light, some we can see others we can't. The majority of emissions are of red and blue light which are easily visible to the human eye but there are also UV, X-rays and gamma rays which are invisible.
What did the Hubble Space Telescope accomplish?
In the 1920s, Edwin Hubble, using the 100-inch telescope at Mount Wilson, California, proved that galaxies exist beyond our Milky Way and showed the universe was expanding, with more distant galaxies flying away at higher and higher velocities.
What was the significance of the Hubble Deep Field observations quizlet?
Hubble observations have high angular resolution, so astronomers can make out details in distant galaxies.
