Astronomers are finding dozens of the fastest stars in our galaxy with the help of images from NASA’s Spitzer Space Telescope and Wide-field Infrared Survey Explorer, or WISE.
When some speedy, massive stars plow through space, they can cause material to stack up in front of them in the same way that water piles up ahead of a ship. Called bow shocks, these dramatic, arc-shaped features in space are leading researchers to uncover massive, so-called runaway stars.
“Some stars get the boot when their companion star explodes in a supernova, and others can get kicked out of crowded star clusters,” said astronomer William Chick from the University of Wyoming in Laramie, who presented his team’s new results at the American Astronomical Society meeting in Kissimmee, Florida. “The gravitational boost increases a star’s speed relative to other stars.”
