Title: Cheap Astronomy – Dear CA #101: More Stars

Organization: Cheap Astronomy


Description: Huh, an astronomy podcast about stars.

– Do other stars have sunspot activity cycles like the Sun does?

Yes, although we say starspots rather than sun spots, when referring to any star other than the Sun. The Sun has an approximately 11 year cycle defined by the number of observable sunspots – which moves from a minimum number to a maximum number over 11 years, and then moves back to a minimum number over another 11 years – hence some people prefer to say it’s actually a 22 year cycle.

– So why are magnetars magnetic?

So, keen listeners will recall that a magnetar is a type of neutron star, all of which do have strong magnetic fields, but magnetars have crazy strong magnetic fields, sufficient to spaghettify sub-atomic particles and polarize a vacuum if you can believe it – not to mention understand it.

Bio: Cheap Astronomy offers an educational website where you’re only as cheap as the telescope you’re looking through.
