New images taken by NASA’s Hubble Space telescope have given astronomers a glimpse of galaxies that were formed just 600 million years after the Big Bang.
The deeper Hubble looks into space the further back in time it sees, because light takes billions of years to travel.
Scientists say from these images, they can observe for the first time galaxies that grew from small, bright clusters of stars to the big spiral cities of stars of today.
While Hubble is tracing the origins of the universe, NASA’s Kepler telescope is seeking out moons that could support life as we know it.
So far it has discovered five new planets beyond our solar system as it looks into the constellation of Cygnus.
Kepler Principal Investigator Bill Borucki is obviously excited with the discoveries.
“They are twenty times hotter than Jupiter. All of these five planets are so hot that they glow. They are hotter than molten lava.”
The planets themselves are huge in comparison with our Earth and while they are unable to serve as a source of life in themselves, their rocky moons orbiting them might.
It is only speculation and possibly wishful thinking, but some go as far as saying that moons like those featured in the sci-fi epic Avatar could turn out to be a fantastic reality after all.
