Supernovae in 3D
We know that supernovae occur when stars explode, but beyond that, there is still much to learn about the 'how' and 'why.' Examining the structure of those explosions could tell us much about the composition and energy involved, but because most supernovae happen so far away, they just look like points of light. A group of Japanese scientists using the Subaru Telescope in Hawaii have developed a new method that measures the polarization, "which supplies information about the direction of vibrating electromagnetic waves," and allows them to construct a 3D image of the explosion, according to the team's press release today. Read more about it and see more 3D diagrams here.
