In this episode, our good friend Professor Jonti Horner, from the University of Southern Queensland, is back to help us answer a big mystery... is there life in other galaxies? We go looking for Alien life in other parts of the Universe to see who or what, is out there....
“This is long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is size — the universe is huge. “Tools like the Hubble Telescope(哈勃望远镜) have shown that there are at least 100 billion galaxies(星系),” says Shostak. “And our galaxy, ...

In the huge universe, there is the Galaxy and many other galaxies. In the Galaxy, there is the Solar System and lots of other stars. In the Solar System, there is the sun, the earth and seven other planets. As we know, the eight planets go around their star ---the sun. In our ...

In ancient times, there was only thought to be one Galaxy, which, as we know, is incorrect. Our star, 'The Sun', is one of many billions of other stars that make up the Milky Way Galaxy. Our Milky Way is one of many billions of galaxies that make up the physical part of the...

Now imagine the other universe where life is nowhere to be found. Stars collide, galaxies explode, meteorites crash, asteroids everywhere. 想象一下有两个宇宙存在。在其中一个宇宙中,每一个星球上,生命都繁荣不息。有的飘荡于空中。有的遨游于大海。有的在海滩上闲荡。各种形态各种大小,任何你想象得到的...
