Three-dimensional models of astronomical objects can be ridiculously complex. They can range from black holes that light doesn't even escape to the literal size of the Universe and everything in between.  But not every object has received the attention needed to develop a complete model of it, but we can officially add another highly complex model to our lists.Astronomers at the University of Arizona have developed a model of VY Canis Majoris, a red hypergiant that is quite possibly the largest star in the Milky Way. And…

As if cracking open a cosmic Russian nesting doll, astronomers have peered into the center of the Milky Way and discovered what appears to be a miniature spiral galaxy, swirling daintily around a single large star.  The star – located about 26,000 light-years from Earth near the dense and dusty galactic center – is about 32 times as massive as the sun and sits within an enormous disk of swirling gas, known as a "protostellar disk". (The disk itself measures about 4,000 astronomical units wide – or 4,000 times the…
