Light echoes and mysterious stars
Karen sent a link to an article at Space.com about a bizarre new nova-like star that is expanding and cooling in a way astronomers didn’t expect. At the same time, it’s giving us a show: a light echo, which is light that bounced off larger and larger regions of dust around the star as the star got brighter.
