How far away is the hubble deep field object to earth?

Answer 1

Light telescopes with a diameter of 30-50 meters are currently planned; probably larger ones will be built in the future. I believe the largest radio telescope has a diameter of about 300 meters. On the other hand, it is possible to connect (through a technique called interferometry) telescopes that are thousands of kilometers apart, so they have the resolving power (but not the light-gathering capacity) of a single telescope that size.

Answer 2

When the Hubble Space Telescope was relatively new, astronomers pointed the Hubble at a tiny area of space in which there were very few visible stars. They discovered that when there are no stars to get in the way, they were able to see thousands of galaxies back to the furthest depths of the the universe.

Answer 3

about 13 billion years ago the objects in the HDF were emitting the light we see today, thus the HDF objects are 13 billion years ago or 13 billion light years away. the universe appears to be 14.7 billion years old, making those images the youngest (or oldest depending on reference) things we've ever seen

by comparison our sun (sol) is 8 minutes ago, or 8 light minutes away.

or another way; the HDF objects are 122990400000000000000000 kilometres away.

Answer 4

We can only guess. The area of space covered was very tiny, but the depth of that observation was mind-boggling.

Back when the Hubble Space Telescope was fairly new (and just after a shuttle mission fixed its misshapen optics) the Hubble scientists pointed the Hubble at a particularly blank area of the sky, an area with no known stars AT ALL. One of the advantages of a space telescope over a terrestrial one is that you can make LONG observations - in this case, nearly a week long. This allows you to detect even very faint light sources.

Within that "blank" area of the sky, the Hubble found galaxies; COUNTLESS galaxies. Where you might see stars on a dark night, the Hubble detected galaxies, very distant galaxies.

Answer 5

The distance you can see with a telescope varies greatly from telescope to telescope. With a low-priced telescope, one could make out the rings of Saturn and the Andromeda Galaxy. With larger telescopes, the distance is increased dramatically. The Hubble telescope has taken pictures of galaxies which lie 12-13 billion light years away.

Answer 6

The Hubble Deep Field objects are located billions of light-years away from Earth. They are some of the most distant objects ever observed by astronomers, providing a glimpse into the early universe.

Answer 7

40 feet long and weighs approximetely 12 tons (in earth weight)

Answer 8

This would depend on what type of telescope you have and what magnification it supports. Mirror Reflector telescopes I believe are at the higher end of the market and can see further.

Answer 9

The HST uses mirrors . The main mirror is 94.5 inches diameter.

Answer 10

Hubble is about the size of a school bus, 40+ ft long, ~7 ft wide.
