Goodbye, cursed August, goodbye. I can't say I've ever been so glad to see a month end. Already my lucky moon is waxing in the west, and a lovely hot September is on the way. Let's make the most of it, celebrate life in the face of constant death, put away our dragged-out summer faces and put on the cool party clothes of autumn nights. As many of you know, September is my month and as I finish up an eventful 41st year, I plan to enjoy every moment.
First, I invite those of you in LA to join me in this year's "pobladores walk" on Monday, 4 Saturday. It's the 225th birthday of Los Angeles, and every year a group reenacts the walk of the original settlers (pobladores) from Mission San Gabriel to the Pueblo. I figured I better go this year, as hopefully next September I'll be far, far away from this evil city. I also figured on going alone...if I can't get you guys out to a movie, how about getting you up at 6 AM on a holiday for a 9 mile stroll, hmm? Not likely. Well, it's your loss...if you're thinking about it anyway you can register here:
Okay, because I'm celebrating the return of the Goddess this month, and since I once pondered becoming an astronomer (well, actually a planetary geologist, but let's not get too technical) I think I need to ruminate for a few moments on the recent designation of Pluto as a "dwarf planet", which leaves our Solar System with only 8 planets. So much for "My Very Eager Mother Just Served Us Nine Pizzas". I hope you don't find this dull, but a lot of angry schoolchildren (and some scientists who should know better) were upset by this change. And I enjoy thinking about these places which are out there waiting for us to walk around on them.
On the contrary to the schoolchildren, I think Pluto and Charon are perfect examples of "dwarf planets", which are now classified as round objects (like planets) but which are unable to clear their orbit (like Ceres, a near-Moon sized body in the Asteroid Belt). The change had to come...we are rapidly discovering round planets in numbers (potential dozens) out beyond Pluto, a snowball-filled ring of junk called the Kuiper Belt. If you thought of our Solar System as relatively empty, this animation will blow your mind; it looks like LAX the night before Thanksgiving:
The Solar System is packed with uncountable rocks and snowballs, and so making Pluto and Charon dwarf planets is almost a promotion...definitely a promotion for Charon, which had been temporarily classified as Pluto's "moon". They're now the largest of these dwarf planets, just as Jupiter is the largest ordinary planet...and many other larger planets are being discovered every month around other stars. Keep reading and you'll see the first photo of one.
Pluto is a really unique object, no matter what it's called. It has more satellites than our Earth...not counting the new dwarf planet Charon, it has two small moons recently discovered, Nix and Hydra, four snowballs spinning around at the edge of our "classic" Solar System. They're the kings of the Kuiper Belt now, appropriate to John Milton's line in Paradise Lost, "better to rule in Hell than serve in Heaven", as Pluto is, after all, the God of the Underworld. The change is an even bigger promotion for that former asteroid, now dwarf planet Ceres, named for the mother of Pluto's girlfriend Proserpina, although you might know them as Demeter and Persephone, their Greek names.
Pluto and Charon are also special because the "barycenter" or center of their rotation is between them...Charon is almost 1/10th the size of Pluto, so rather than orbiting Pluto like a moon, they circle together, each facing the other. From the inner side of either dwarf planet, the other would hang forever motionless in the sky...a dramatic sight that one of our great-grandchildren might get to see in person. This dance will go on essentially forever...even after the Sun has become a red giant in a few billion years, and burnt our poor planet to a cinder (along with Mercury, Venus and probably Mars), Pluto and Charon will continue to dance. They move apart so slowly that only their kind of energy, angular momentum and gravity, will survive to the end of the universe, long after every star in every galaxy has been used up and gone out.
Only four other objects in the Solar System have this kind of relationship, where the barycenter is well away from the center of the larger pair. The first two, natch, are our very own Earth and Moon. Our barycenter is only 1700 km below the surface of the Earth, not even halfway to the center, and so the Moon creates a terrific drag on us, slowing us down (a day used to last only 18 hours) and creating nice tides for my surfer friends. Our gravity stopped the Moon from spinning, and so it faces us for the rest of its life...by the time the Sun explodes, the Moon will also have stopped us, so one day here will be a month long, and like Pluto and Charon, we'll dance facing each other. Which continent will be facing the Moon? By then all the continents will have moved apart and crashed together again three or four more times, so who knows...and the oceans will have evaporated into outer space. In other words, don't hold your breath.
The other pair of objects with an unusual barycenter are the Sun and Jupiter...they spin around a point just above the surface of the Sun. That's pretty amazing, because Jupiter is five times further away from the Sun than we are (although it's many dozens of times larger). If Jupiter was only 10 times bigger, it would flame into life and we'd have two suns in the sky. Of course, this means that Jupiter, technically, is not a planet either, but has a privileged relationship to the Sun. They circle a common place outside of both, like many binary stars. Jupiter is also strange because it spins so fast...I mean it really hauls ass, rotating in only ten hours, or ten times faster than the Earth (not twice because it is so much larger). Even the Sun only spins twice as fast as us, taking almost a month to rotate.
The mechanics of all this fun stuff can be explored in greater depth at this excellent website:
By the way, as of 1986, the Moon was not the only large object technically in orbit around the Earth. A rock with the boring name of 3753 Cruithne rolls in the Earth's orbit around the Sun, but in a spiral, so from here it looks like a corkscrew. It flies just outside of us, a little slower, and when we pass by, our gravity drags it just inside of our orbit, making it a little faster than us, until it passes us and we spin it back out. Now this is a wonderful dance, although this rock eventually will get too far away and spin off alone in the dark.
Well, that's enough rambling about the neighborhood of planet Earth, which is officially known as Terra, or in "Star Trek" speak, "Sol 3". By the way, here's the FIRST photograph of a planet outside the Solar System, a gas giant like Jupiter orbiting a brown dwarf star. Unfortunately it has the depressing name of 2M1207 1.
You might want to take a greater interest in outer space, because if we're not careful, it's the only place we'll be able to live soon:

It would be nice if everyone gave the Goddess a hand, because the impact of global warming is more obvious than just a hot summer:

Earlier this week, editors and publishers from around the country met in Chicago for The Associated Press annual meeting as well as other newspaper-related gatherings. Aside from topics dealing with specific newspaper matters, the one main topic of discussion was the energy crisis and oil. The AP put on an interesting program with the correspondents from Africa, China, Washington, D.C., and Los Angeles reporting various aspects of this countrys dependence or addiction to oil.

It is not just the state of California that is bypassing the authority of the US government to take action on global warming.

Neil Peirce Ocean Power Can Be a Global Warming Cure
Ocean tides and currents are an overlooked source of energy: "A major pilot demonstration seems ready to launch in San Francisco Bay, where an immense tidal flow enters and exits every day at a narrow point of the Golden Gate.... It will produce electrical energy that can then be transmitted to shore by cable," writes Neil Peirce.
A scientist at USC came up with this idea, almost like a wallpaper (or a fabric...think of the clothes!)
