Using the best technology available, how far can you see things clearly? As in how many light years?

jackmell said:When you say "how far", I immediately think of the Hubble Deep Field and the Ultra-deep field. Are you aware of these two images?
Depends on what "the happenings" are.siddharth23 said:Given enough clarity and exposure, is it possible to observe the happenings in, say, Andromeda?

GeorgeDishman said:About 5.8 billion light years. That corresponds to a red shift of about 1.64. We can see light from objects which has been traveling for longer but those objects were closer when the light was emitted.
The resolution of our best telescopes is good enough to:siddharth23 said:Like volcanos on the surface of a planet. Just a crude example. Something like that.
davenn said:probably a bit hopeful there ;)
I would suggest its substantially less than that
yes we can see objects at several billion lightyears. but resolving ones out to a few 100 million ly's
note what the OP said ... "how far can you see things clearly? "
Russ's response gives a better idea of resolution problems
The best telescopes on Earth are currently capable of seeing objects up to 13 billion light years away. This means that the light from these objects has traveled for 13 billion years to reach Earth, giving us a glimpse into the early universe.
The distance a telescope can see is determined by several factors, including the size and quality of the telescope's primary mirror, the atmospheric conditions, and the sensitivity of the telescope's detectors. The larger and more precise the primary mirror, the further the telescope can see.
Yes, the best telescopes are capable of seeing objects beyond our own Milky Way galaxy. In fact, many of the objects that we can see with telescopes are located in other galaxies, giving us a better understanding of the vastness of the universe.
Yes, the distance that telescopes can see has increased over time as technology and techniques have improved. The best telescopes today are able to see much further than the telescopes of the past, allowing us to see deeper into the universe and further back in time.
Yes, there are telescopes in space that are able to see much further than Earth-based telescopes. These include the Hubble Space Telescope, which has a clear view of the universe without the interference of Earth's atmosphere, allowing it to see objects up to 13 billion light years away.
