We all know what the Moon looks like, with its crater covered surface. However, lunar swirls are less obvious to the naked eye and even scientists have long wondered what they were, despite having been discovered way back in the 1600s.

00:00this is the moon something we can all see nearly every night shining brightly in the sky however
00:08these lunar swirls are less obvious to the naked eye and even scientists have long wondered what
00:13they were despite having been discovered way back in the 1600s however a new study posits
00:18an explanation for one of these swirls specifically called the reiner gamma swirl the moon no longer
00:24has a central magnetic field and magnetosphere however researchers now say that it must have
00:28small localized magnetic fields and that could have caused these swirls they say that when the
00:33sun's rays hit the lunar surface these many magnetic fields protect some parts but not others
00:38this causes a chemical reaction over time producing these iconic splotches of gray and well lighter gray
00:44still the cause of these isolated magnetic fields is still a bit of a mystery with the researchers
00:49writing impacts could cause these types of magnetic anomalies but there are some swirls where we're not
00:54sure how an impact could create that shape and that size of thing with a study outlining how it could
00:59be that subsurface lava could have cooled slowly in a magnetic field creating these magnetic anomalies
