On July 19th, while looking through his amateur telescope at Venus, astronomer Frank Melillo, from Holtsville, NY, caught sight of what appeared to be a bright spot on the surface of the planet. The bright phenomenon suddenly appeared in the atmospheric clouds, and its origin left scientists completely in the dark. Expert Sanjay Limaye, a planetary scientist at the University of Wisconsin-Madison, says that this is not the first time the unusual phenomenon has been noticed on our neighbor, but that the source is still a mystery. After the amateur astronomer discovered the bright spot, the find was confirmed by other members of the community, as well as by the Venus Express spacecraft, operated by the European Space Agency (ESA). Limaye said in an e-mail for Space that its appearance was gaining so much attention precisely because it had occurred just days after Jupiter developed a new dark spot of its own, most likely due to a comet hitting it. The gas giant now sports a d!

Venus Express measurements of the region determined that the spot actually grew on Venus four days before Melillo saw it, and that it since spread throughout the thick atmosphere, via strong air movements. At this point, there are several theories as to why the spot appeared. Some astronomers believe...
