Institute of Technology astronomers use new 3-D imaging techniques to map a hypergiant star's massive outbursts

A group of astronomers led by Institute of Technology Professor Roberta Humphreys have combined images from NASA’s Hubble Space Telescope and the W.M. Keck Observatory in Kameula, Hawaii, to create the first-ever, images of one of the brightest supersized stars in the sky.

From these new images astronomers have learned that the gaseous outflow is more complex than originally thought from VY Canis Majoris, a red supergiant star. More...
