| Size comparison of terrestrial planets (left to right): Mercury, Venus, Earth, and Mars |
Studies of Venus have suggested that several billion years ago Venus was much like our own planet with liquid water on the surface, but a runaway greenhouse effect caused the evaporation of all the liquid water to evaporate into it's atmosphere.
Venus will be having some nice pairing in the sky in the coming months with the Moon, Jupiter and Venus in the coming months. These are excellent for observers and photographers alike, so be ready with your telescope or camera. Find a nice setting with a foreground object like a tree or building which would make make a nice picture. Always use a tripod when you can so your picture can be as sharp as possible.
