Feature Guest: Terry Kucera We see it there in the sky every day of our lives. And yet our own local star, the sun, is still in many ways a mystery. What causes the solar cycle?

You’ll never look at the sun the same way again after we’re joined here The Star Spot by NASA astrophysicist Dr. Terry Kucera Current in Space As we focus today's feature interview on the Sun, Tony reminds us not to forget about the moon, and he competes for our attention with a startling new conjecture that rivals the mainstream theory for the origin of our close companion.
