![]() ![]() ![]() In our solar system, activity on the sun can create space weather that impacts Earth. “This idea is what we’re calling ‘extrasolar space weather.'” ![]() “This is telling us new information about the environment around stars,” Pineda said. The researchers measured the radio waves they detected to determine the strength of the planet’s magnetic field. All of these energetic reactions create and release strong radio waves that can be detected on Earth. While YZ Ceti b whips around its star, plasma from the star collides with the planet’s magnetic field, bounces off and interacts with the star’s magnetic field. Meanwhile, the shortest orbit in our solar system is the planet Mercury, which takes 88 Earth days to complete a lap around the sun. YZ Ceti b only takes two Earth days to complete a single orbit around its star. If the planet has a magnetic field and it plows through enough star stuff, it will cause the star to emit bright radio waves.” “These planets are way too close to their stars to be somewhere you could live, but because they are so close the planet is kind of plowing through a bunch of stuff coming off the star. “We’re looking for planets that are really close to their stars and are a similar size to Earth,” she said. “What we’re doing is looking for a way to see them,” said study coauthor Jackie Villadsen, assistant professor of physics and astronomy at Bucknell University in Pennsylvania, in a statement. ![]()
