Sure, you’ve seen the Moon countless times, and perhaps you’ve been drawn out, zombie-like to view this weekend’s “Super-Moon,” but have you ever seen the moon in… cosmic rays?  This is but one gem that has come out of NASA’s Lunar Reconnaissance Orbiter (LRO). [Read more...]

17.9.9: A Farside Sunspot Group?

Activity on the Sun may be finally picking up. Specifically, a new sunspot group has been “seen” up forming on the farside of the Sun. That’s right; astronomers can now model the goings-on within the Sun with such precession, thanks largely to satellites like SOHO and the GONG network, that we can now predict with some confidence whats going on on the side of the Sun turned away from us! This is mostly due to a growing sub-branch of astronomy known as helioseismology. The Sun itself rotates at about once every 25 days, although this varies by latitude because the Sun is essentially a big rotating gas ball. The twin Stereo spacecraft are also slowly inching their way out into leading and trailing orbit(s), providing us with a good “peak” around the limb. If you own a solar scope, the next week or so might be good cause for increased monitoring; the new solar cycle #24 might just be ready to put on its first show!
