The star, HD 162826, was identified by Ivan Ramirez and his team at the University of Texas at Austin. It's located 110 light-years away in the constellation Hercules, is about 15% more massive than our sun, and is not visible to the naked eye.
Ramirez's team was able to match this star to our own by following up on 30 possible candidates. The astronomers used high-resolution spectroscopy to get a better understanding of the chemical make-up of these stars. In addition, they analyzed the orbits of these candidates, namely where they have been and where they are going in the paths around the center of the Milky Way.
less a home is tricked out with security cameras or police can find clear evidence, if a burglar breaks in, there's no way of knowing whodunit. Even if a victim sees the perpetrator and sits down with a sketch artist, memory can be faulty or biased—just ask the countless black men who've "fit the description."
A group of Penn State University researchers have developed a technological solution that uses the one part of us that never lies: DNA. Led by anthropologist Mark Shriver, the research team has created computer software that generates a 3-D facial model. All it needs is something—a hair, a fingernail, or saliva—with your genetic code.
