Life in Our Solar System

Astronomy- Is there life out there?

Billions of creatures live In our Universe. We humans are just one kind. Many more creatures and plants live on land and In water. From single celled structures to multi intelligent beings.

As far as we know there Is no life outside of Earth. Most Astronomers believe that It Is inevitable that we will eventually find something, whether Its microbial or intelligent remains to be seen. At one time early Astronomers believed that the planet Mars was Inhabited by martians and that the lines and ridges on the planets surface were actually roads and canals. The Ice on Mars can be found at Its northern and southern poles.

Mars isn’t suitable for life today but It may have been In the past. There Is water on Mars, however It Is frozen now. Future probes to Jupiter’s moon Europa may show signs of life beneath Its Icy surface.

Our Galaxy alone has thousands of planets and moons that are capable of harbouring life. Finding out will not be easy as the nearest Star with planets Is beyond our present reach. At our constant best speed, a space probe would take billions of years to get there. If however we could find some way to travel at the speed of light 300km per second It would only take us 25 years to reach our nearest star Proxima Centauri. Astronomers have already found hundreds of other planets In our Galaxy, Its only a matter of time until we find some forms of life on them.

    Excellent. Great pictures too. My only quibble is that Alpha Proxima is just FOUR light years away (but still FAR).

    I am sure there is other life but I think its best that we do not find it and it does not find us.

    Sorry Butman, I was refering to our nearest star with known Exo planets. I should have been more clear.
