Water on Mars

New pictures from Mars have revealed that water was running freely on the red planet about one million years ago.

Images from a NASA spacecraft orbiting the planet show fan-shaped gullies on the surface that seem to be about 1.25 million years old.

Experts think the channels were created by surface water from melting ice and say it may represent the most recent time when water flowed on the planet.

    Couple Trouble: Reasons For Breaking Up   Pretty Petty Problems These are the reasons why couples breakup.  Problems that is so small that sometimes causes couples to breakup.   -He doesn't reply to your messages -He is not thoughtful, for example he/she forgets that it's your monthsary or what anniversary you guys are suppose to celebrate -He is not a gentleman -Different lifestyle -Super talkative -- or maybe the opposite Fight for Love: There may be a second chance for the both of you, because these are only small reasons which may be solved by meeting halfway.  Remember, to each his own.  You need to accept and respect who he is --- that's the foundation of a potentially long-lasting relationship. Take Flight: The reasons why you don't like him outweigh the reasons why you like him.  It would be difficult to work out a relationship with someone who's qualities don't meet your standards.
