Towers of effulgent jack-o-lanterns line the picturesque streets of Keene, New Hampshire, with more pumpkins aglow than there are inhabitants of the small town.
Another way to gather information would be to transport a vessel to and from the planet. The technology exists to do this, but at 20 light years from the Earth, it would take 200 years for astronomers to receive the result.
A US-British team of astronomers discovered a planet 1,200 light years away with ultra-high concentrations of carbon. This supports the idea that it could have mountains made up of diamonds.
A new picture helps scientists unravel the mystery of a vast green blob discovered in a galaxy millions of light years away. Part of a streamer of gas stretching around the galaxy, it may be giving birth to new stars.

Discovered on Sept. 18, 2006, the explosion actually transpired in a distant galaxy about 238 million light years away -- meaning it happened about 238 million years ago.
On our last day we took a scenic route through the old city. The lights, buildings, and river were truly spectacular. What great way to wrap up our trip.
All night, every time you breathe out, carbon atoms take off into the night air. Each carbon atom weighs a tiny fraction of a gram. But every breath expels roughly ten billion trillion atoms, so you wake up a pound lighter.

However, really distant, and therefore older, galaxies recede from us so rapidly that much of their light is transformed - by an effect known as the Doppler shift - into microwave radiation.
