What is the Hubble Deep Field?
Q: What is the Hubble Deep Field?
A: The Hubble Deep Field is an image of a small part of the night sky taken by the Hubble Space Telescope in 1995.
Q: Why is the Hubble Deep Field important?
A: The Hubble Deep Field is important because it shows some of the earliest galaxies ever seen, over 3000 in total. It allows scientists to look at what the Universe was like over 10 billion years ago and how it has changed.
Q: In what direction was the Hubble Deep Field taken?
A: The Hubble Deep Field was taken in the direction of the constellation Ursa Major.
Q: What is the area of the sky that the Hubble Deep Field was taken in?
A: The area of the sky that the Hubble Deep Field was taken in makes up less than 1/10th the width of a full Moon.
Q: How many galaxies are in the Hubble Deep Field?
A: There are over 3,000 galaxies in the Hubble Deep Field.
Q: Why do many galaxies in the Hubble Deep Field look the same as they did over 10 billion years ago?
A: Many galaxies in the Hubble Deep Field look the same as they did over 10 billion years ago because of the time it takes for light from these galaxies to reach Earth.
Q: What is the cosmological principle in relation to the Hubble Deep Field?
A: The cosmological principle, which suggests that on large scales the Universe is roughly the same no matter what direction you look, is important in relation to the Hubble Deep Field. It becomes a very important tool for astronomers studying how the Universe has changed.
