00:00Despite being the brightest and largest thing around, the Sun still holds quite a few mysteries
00:08for scientists. One of those includes its heartbeat, periodic signals released by our
00:13solar system's central star that appear rhythmic. Now experts say they believe they have figured
00:18it out, and there are far more cosmic bodies involved. While much of that heartbeat involves
00:22internal solar processes, the rest of the planets in the solar system are quite in sync with the
00:27Sun's 11-year solar cycle. Experts say this means that the planets are likely involved in this
00:32rhythmic beating, with the entire system being part of what they are calling a gigantic dynamo.
00:36With physicist Frank Stefani saying about their findings,
00:39While this solar dynamo generates an approximately 11-year solar cycle in its own right, we think
00:44the planet's influence then intervenes in the workings of this dynamo, repeatedly giving it a
00:49little push, and thus forcing the unusually stable 11.07-year rhythm on the Sun. This is likely due
00:56to a point every 11.07 years when the Earth, Venus, and Jupiter all line up. This causes immense
01:02gravitational forces on one side of the Sun, all pulling in one direction, possibly synchronizing
01:07the solar dynamo. The researchers say this could finally explain why the Sun goes through an 11-year
01:12cycle, but also the shorter cycles in which it undergoes coinciding with other planetary lineups.
