In the universe at z >~ 2, galaxies with various morphologies are seen, and star-forming galaxies at z ~ 2 show the intrinsic shape of bar-like structures. Then, when did the round disk structure form? Here we take a simple and straightforward approach to see the epoch when a round ...
It wasn't until the 1970s that two brothers, Alar and Juri Toomre, revisited the issue. Using actual computers to simulate the behavior of merging galaxies, they found the smoking gun: When two galaxies merge, the gravitational interactions raise "tidal tails" of gas and stars — long, thin...
Our universe is home to countless galaxies(银河), with each galaxy hosting hundreds of billions of stars. Each one is a ball of energies powered by the nuclear explosion of elements in their hearts. 1 But when did the first stars shine?
SPACE.com: How common are galaxy collisions? Lanz:As we understand the growth of galaxies over the entireage of the universe, we really think that small ones form and then clump together to form bigger ones. So really any large galaxy will have had multiple of these events. Whether it's ...

Stars form within clouds of dust and gas known as the interstellar medium within galaxies. This interstellar medium is mostly made up of hydrogen and some carbon and silicates. The temperature of this medium is also very cold causing the ingredients to bind and clump together. The result is ...

Already, this looks like a huge mistake: the new space telescope has produced embarrassing images of ancient galaxies that shouldn’t exist. We won’t dig into the Big Bang question here mostly because things are changing so fast almost anything I think to type will be obsolete before it ...
there is an external time beyond which you will never reeceive any information – your view of the future is drastically restricted. The junk about “being deposited elsewhere” is just that. It is true that local solutions exist that show this condition (albeit not in theform usually picked...
