Keep the Shiny side up


If the Sun doesn't get it, that'd be a nice Christmas present for 2013.

There could be a vampire ship hiding inside. Mathilda May hasn't been seen in a long time.

I remember the fuss over Halley's, back when it came 'round. I recall thinking I'd be around for it on the next trip, but we'll see about that.

Hale-Bopp was the clearest, most 'classic' comet I recall. Hyakutake was hardly visible at all, at least where I saw it. I recall its tail being rather dispersed.

Kohoutek was the most over-hyped one I remember. I've read that the biggest fear with this one is that the initial thermal pulse from the sun may cause it to shatter.

Personally, I'm hoping to live long enough to see Betelgeuse go supernova. That would be a sight!

...then there was Kohoutek. What a bust. Forgot about that one.

Shoemaker - Levy 9 was very significant, though not seen by the naked eye of course.

And yeah, Betelgeuse or VY Canis Majoris, which ever goes first.

But speaking of Betelgeuse, here's a timely article I just saw...

Quote:

The red supergiant star Betelgeuse in the famed constellation Orion is on a collision course with a strange wall of interstellar dust, with the clock ticking down to a cataclysmic cosmic smashup in 5,000 years, scientists say.

A new image of Betelgeuse by the European Space Agency's infrared Herschel space observatory, shows that the star will crash headlong into a trail of space dust while speeding through its part of the cosmos at a blistering 18.6 miles (30 kilometers) per second. That's about 66,960 mph (107,761 kph).

Betelgeuse is a giant star that makes up the left shoulder of the Orion constellation and can easily be seen from Earth with the unaided eye by observers in the Northern Hemisphere. The star appears as a reddish-orange light above and to the left of Orion's belt.



Too bad none of us will be around for THAT collision, if it hasn't exploded before then.

It is my goal to see Halleys someday. It came over when I was a baby, so I'll be about 76 or 77 when it comes around again, talk about inconvenient. There's a cute song called When Halley Came to Jackson in 1910. A bit over sentimental, but still worth noting in a thread about commets.

Also worth noting is that Mark Twain was born when it came over, and he died when it came over again. I think that's really neat, really something, he has a link to it.

Now there's a freaky fact! I bet the Heaven's Gate folks took that info to heart.

The appearance of Halley's Comet in February 1986 was the least favorable sighting in modern times. The comet and the Earth were on opposite sides of the Sun. I had a small telescope then, and my friend and I drove down to the old unlit Seven Mile Bridge in Marathon, Florida to get a great view in the darkness of the area. But I was able to see it only for a short time because of the cloud cover. It was quite disappointing. That was it for me unless I live to be 109.

Comets: signs of impending omen. Or at least the birth of a first-class smartass.

I note that if the story is true then technically Twain never saw Halley's comet either time.

Interesting Halley history.

Quote:

n 1687, Sir Isaac Newton published his Principia, in which he outlined his laws of gravity and motion. His work on comets was decidedly incomplete. Although he had suspected that two comets that had appeared in succession in 1680 and 1681 were the same comet before and after passing behind the Sun (he was later found to be correct; see Newton's Comet), he was unable to completely reconcile comets into his model. Ultimately, it was Newton's friend, editor and publisher, Edmond Halley, who, in his 1705 Synopsis of the Astronomy of Comets, used Newton's new laws to calculate the gravitational effects of Jupiter and Saturn on cometary orbits. This calculation enabled him, after examining historical records, to determine that the orbital elements of a second comet which had appeared in 1682 were nearly the same as those of two comets which had appeared in 1531 (observed by Petrus Apianus) and 1607 (observed by Johannes Kepler). Halley thus concluded that all three comets were in fact the same object returning every 76 years, a period that has since been amended to every 75–76 years. After a rough estimate of the perturbations the comet would sustain from the gravitational attraction of the planets, he predicted its return for 1758.

I know I'm not supposed to believe in omens, but I ... kind of do in a different sort of way. Mark Twain was certainly worth remark after all. Also worth noting is that my dad and I chose ravens as our "totum" when I was 15, I put it in quotes because our view of it isn't exactly the classical view of it, more like its an animal you feel connected to, that you see as good when it is near you, that God could use to get your attention etc. Anyways about nine months later my little brother was born (he's adopted, but we've known him since he was born, didn't come to live with us until later though) and his biomom named him Raven, without any prompting from me or anyone, its just what she did. My mom and her husband were like grandparents to him for the first few years, then he was taken away from mom and came to us. But yeah, my lil' brother is my totum too. He is a gift of gifts, he is the missing piece that I knew I was looking for all through my girlhood, I knew something was lacking until he came along. Can you tell we're really close?

For all we know, Betelgeuse is long gone.
