Where: Venus
When: February 25, 2009
What: The ESA's Venus Express spaceship observed that there was a glow around Venus durning nighttime. This glow is impossible to see with the naked eye, however, the scientists saw it using a Infrared Thermal Imaging Spectrometer(VIRTIS) which is something used to see wavelengths.
Why: The glow was caused by the Sun's ultraviolet light rays.
My Opinion: I think it makes a lot of sense that the weird glow was caused by UV rays since Venus is right by the Sun. Also, I wonder if the scientists were shocked when they saw this or if this happens often.
