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.
According to Hubble's Law, the farthest galaxies in the universe appear to be receding from us at higher velocities than those that are closer. This phenomenon is observed as a redshift in the light from these galaxies, indicating that they are moving away due to the expansion of the universe. The greater the distance of a galaxy, the faster it seems to be moving away, which supports the idea that the universe is continuously expanding. This relationship is key evidence for the Big Bang theory.
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.
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.
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.
Yes, all 100 billion galaxies in the observable universe up to 13.5 billion light-years away.
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.
The closest star is the Sun - about 8 light-minutes away. The closest star after that is at a distance of 4.3 light-years; the farthest observable galaxies (galaxies are made up of stars) are at a distance of over 40 billion light-years.The closest star is the Sun - about 8 light-minutes away.
