Thecurrent record holderis a galaxy a staggering 34 billion light years away, seen just 200 million years after the Big Bang, when the universe was 20 times smaller than it is now. Edwin Hubble would be amazed to see such progress. Written by Chris Impey, University Distinguished Professor o...

The universe is expanding and every galaxy is moving away from every other galaxy. Astronomers believe that the universe began fifteen thousand million years ago. There are one hundred thousand million galaxies in the universe. Some astronomers believe that the universe will stop expanding, and the...

Our galaxy is approximately 100,000 light-years from edge to edge. It would take longer than the age of the entire universe for us to launch a camera outside the galaxy far enough to take the image; it would then take many millennia for the radio waves to travel back to us with the...

A galaxy is a group of billions of stars orbiting a common centre. Many of these stars have planets orbiting them.If you can believe it, the universe is even bigger than that! Outside our galaxy are billions of other galaxies.The universe is huge!universe n. 宇宙neighbourhood n. 邻里...
bigger and brighter than the moon.They look smaller than the moon also because they are farther away from us.It's clear that big things will look smaller when they are farther,and small things look bigger when they are nearer.So far,we have traveled to many other planets in the universe...
giving rise to hypervelocity stars which will leave the galaxy, so the team proposes a threshold that the galaxy have a "relaxation time" greater than the age of the universe. This would allow dSphs and UCDs to be considered galaxies, but would keep out objects that have generally been cons...
A light-year is 5,878,625,373,183.608 miles. Therefore, the centre of the Galaxy is very, very far away.Galaxy vs. Universe A Solar System is the smallest of the three subject matters. It covers the area of a Star's Heliosphere. Inside is the star and all the orbiting Planets, ...
