Venus

Venus

 Venus was named after the Roman goddess of love and beauty. Venus is the second brightest natural object in the sky to the moon. It reaches its maximum brightness shortly before sunrise, and shortly after sunset, and that is where it has gotten its name "the morning star," or "the evening star." Venus is called earth's "sister planet" due to similar size, gravity, and bulk composition. Venus's clouds of sulfiric acid prevent it from being seen from space in visible light. Venus's surface is a desert with many slab-like rocks, constantly refreshed by volcanism, or volcanoes and volcanic activity. Venus's atmospheric pressure at the surface is ninety-two times more than Earth's surface.The sulfur in the atmosphere indicates that there have been recent eruptions. The absence of lava evidence remains a mystery. Venus has no carbon cycle, and it does not seem to have any organic life to absorb it.

 There is also no evidence for plate tectonics on Venus, possibly because its crust is too strong to subduct, or where one tectonic plate sinks beneath another.





This is an optical illusion created by STEREO optics.  As Venus moved beyond the field of vision it seemed to flare back into view. I just thought it was kind of interesting looking.
