First photo is from a news story received today on the possibility of ancient life existing on Mars.
This is a very interesting article on correspondences between formations seen there under varying conditions and those we know of here.
Second photo is from Amazon's Free Android App of the Day, normally $2.99 and one that many families (and schools) will want to explore. Some beautiful work was put in on this, and it's very informative.
I'm just sending off this alert, as there are only 5-1/2 hours left, after I noticed it, and those who are tuning in might want to take advantage of it.
