article_snippet.sent: This simulation shows how the outflow of material from a star has dramatically expanded as This simulation takes shape.
article_snippet.sent: But what has most excited astronomers is the change in shape of the violet area of super-hot electrified winds that are being ejected by a star.
article_snippet.sent: The pictures, created by data from 27 radio telescope antennae in the New Mexico desert in the U.S., show the electrified wind expanding away from a star until it is slowed by the black and yellow cloud of dust surrounding it.
article_snippet.sent: On the left is a star as seen in 1996, with a star dust wrapped tightly around a star, while by 2014 in the image on the right, this outflow has been pushed out into an elongated shape .
article_snippet.sent: On the left, a hot wind from a star expands nearly spherically, as seen in 1996.
article_snippet.sent: On the right right, as seen in 2014, the hot wind has been shaped by encountering a dusty, doughnut-shaped torus around a star and appears elongated .
article_snippet.sent: In the 1996 picture there is a relatively small region of space wind surrounding a star.
article_snippet.sent: But 18 years later that has expanded into a rugby-ball shape – because the dust has formed a doughnut shape around a star and offers less resistance to the space winds at a star poles.
