Thomas Leveritt recently captured footage of a series of people with an ultraviolet camera. According to Leveritt, "an ultraviolet camera can show not-yet-visible changes" on people's skin, which means lots of freckles. He then had people put on sunscreen to demonstrate how it protects their skin.
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.
