Considering, we can only observe light, the furthest known object is UDFj-39546284 a stellar structure. At the time of observation it was about 13.2 billion light years from us.
However, since that time, it is now possibly 32 billion light years from us and getting further away.
Yes. The farthest parts of the observable Universe are getting away from us, faster than the speed of light. The Wikipedia article on "metric expansion of space" can give you more information.
The longest space journey in terms of time would likely be a mission to the farthest reaches of the observable universe, such as the edge of the cosmic horizon, approximately 46.5 billion light-years away. Currently, with our fastest spacecraft, it would take millions of years to reach even the nearest stars, let alone distant galaxies. However, since space travel at such scales is currently beyond our technological capabilities, any journey to the farthest parts of the universe remains purely theoretical and would span countless human lifetimes.
They can't. The universe is only about 13 billion years old. If there are galaxies a trillion light years away their light has not reached us yet and due to the expansion of the universe, never will. At the edge of what we call the observable universe we cannot make out individual stars, but we can detect galaxies using infrared telescopes.
One trillion light years away from Earth would be an extremely distant region in the Universe, likely beyond the observable Universe. The vastness of such a distance makes it difficult to comprehend, but it would likely be in a remote part of space where galaxies and other cosmic structures are spread far apart.
The observable Universe is the part of the Universe we can see from Earth because the light from all the objects in it has had enough time to reach us. Light from outside the observable Universe has yet to reach Earth. The reason we can only see part of the Universe is because of the limited speed of light, and the expansion of the Universe, which is faster than that speed. According to Einstein, nothing in the Universe can move faster than light, but nothing stops the expansion of space from moving faster than light. This results in a large part of the Universe being completely invisible to us.
There is no such thing as the "center of the Universe". It is believed that the Universe looks the same from different places, there is no way to determine a "center". The farthest observable galaxies move away from us, at several times the speed of light.
The farthest objects we can observe are galaxies that are around 13.8 billion light-years away. This distance is governed by the age of the universe, as light from these objects has taken the entire history of the universe to reach us.
The farthest parts of the observable Universe are getting away from us at several times the speed of light. LOCALLY, the objects (like galaxies) move at speeds below the speed of light, but in this case, it is space itself that is expanding, faster than the speed of light.
Yes, all 100 billion galaxies in the observable universe up to 13.5 billion light-years away.
The Hubble Space Telescope can see objects billions of light-years away, allowing it to observe distant galaxies, nebulae, and other astronomical phenomena. Its high-resolution images have provided valuable insights into the universe's history and evolution.
There is not a ''farthest galaxy'' in the universe. But thereslotte is a very far galaxy.
In Virgo, and in all other constellations, astronomers can see objects all the way to the edge of the observable universe. Some of these objects are galaxies containing billions of stars.
Yes. The farthest parts of the observable Universe are getting away from us, faster than the speed of light. The Wikipedia article on "metric expansion of space" can give you more information.
It depends on exactly what you're measuring. The vast majority of cosmologists (that is, essentially all except for a few kooks) think that the universe is expanding. That, coupled with the speed of light, means that the most distant objects we can see appear to be at the distance they were from us several billion years ago, and since the universe is expanding, "now" they are further away than that. The observable universe is a sphere around 28 billion parsecs in diameter. The observable universe is itself expanding with time. However, for complicated reasons the observable universe (that part of the universe we can see) will eventually stop expanding, at a diameter of about 38 billion parsecs. Anything outside this distance is moving away from us faster than the speed of light (because of the expansion of space itself), and its light can never reach us.

While there is some seemingly random movement, in general the objects are moving away from one another. In other words, the Universe is expanding.
Receding from each other faster the farther away they are. He saw they were "red shifted" and the red shift was greater the farther away the galaxy was. This mean that the Universe is expanding.
Objects in space are moving away from each other due to the expansion of the universe. This expansion causes galaxies and other celestial bodies to drift apart over time. The further away an object is, the faster it appears to be moving away from us.
