[edit]DescriptionThe Evening Star a Double Take (2859183621).jpg |
People often ask why so many pictures from robotic space probes are presented in black-and-white or in false color. This image is one example that shows why. It's a composite of two recently-released shots of Venus from Europe's Venus Express orbiter. On the left is what the planet looked like in visible light: a nearly featureless orb of highly-reflective clouds. That makes for a brilliant 'evening star' or 'morning star' in the night sky here on Earth, but doesn't provide much scientific information. On the right is a shot taken at about the same time through a filter sensitive to ultraviolet light, which the human eye can't see. The result is in one sense "false color" but in another sense is even more true to life, revealing new details about the planet's turbulent atmosphere that would otherwise remain hidden.
