Today NASA announced that liquid water still flows on the surface of Mars! Well, this is the second best announcement about Mars that we could wish for – the first being of course that they found life! Hmm, perhaps a little disappointing but who knows, that announcement could come sooner than we think.
Well the fact that there is liquid water on Mars significantly increases the possibility of life on Mars and also it makes things a lot easier for humans to someday visit and colonize the Red Planet.
Actually water, which is the most important aspect for life as we know it, is not as rare as we once thought. Apart from Mars – our own moon, Enceladus (a moon of Saturn) and Europa (a moon of Jupiter) are believed to also have plenty of water. Signatures of water have also been found around planets orbiting around distant stars as well.
Where water is, life cannot be too far away. So it is just a matter of time before we discover life outside our own world. Slowly but surely most of the scientific data that we are receiving is making the answer imminent – we most certainly are not alone!
