Two rocky planets have collided, destroying each other in the process and leaving a massive ring of dust surrounding a star almost 300 light years from our sun.
"It's as if Earth and Venus collided with each other," Benjamin Zuckerman, Professor of Physics and Astronomy at UCLA, said. ...
The implications for any life on the worlds would have been disastrous.
"If any life was present on either planet, the massive collision would have wiped out everything in a matter of minutes, the ultimate extinction event," he said.
"A massive disk of infrared-emitting dust circling the star provides silent testimony to this sad fate."
