In August 2006, the International Astronomical Union (IAU) released a controversial definition of "planet" that left Pluto out. But some astronomers were against this definition that demoted the distant orb.
JAXA astronomers discovered two red rocks in the asteroid belt between Mars and Jupiter where they should not be. Both rocks are found to have a complex organic matter that might hint at the chaotic origins of the Solar System.
Both Jupiter and Mars are bright planets, but neither of them could compare to the brightness of Venus. It is easily visible from the Earth and at times shines even brighter than usual. So, how did this neighboring world become so bright?
