New Scientist for Dec 14, 2002, had a cover story for Planet X:
The Hunt for Planet XJust over a year after the New Horizons' launch, it will... pick up enough velocity to reach Pluto, possibly as early as July 2015... In their new research, Melita and Brunini have explored three possible reasons for the Kuiper Cliff... The third possibility is that the region beyond was brushed clear by the gravity of Planet X... the KBO orbits they have investigated so far fit in best with the influence of a Planet X.

Me with the prayer request pinglist, two different devotional lists (done at irregular times), my new one for wildfire news,
and one other. It does add up!
Thanx for the invitation ... I'm already on too many ping lists to keep up with! I'll have to pass.
No problem. Hey, if you want, I've got another, huge, ping list for those who are on too many ping lists. The catch is, there are *never any pings* from it. Some people don't care for that... ;')
I think Patrick Henry already has one of those 'never pings anyone on the list' lists and I think I'm on that one, although I've never gotten a ping from it to verify. [Flogiston anyone?]
PH has a quite a number of those, whipped up at the spur of the moment. :') I ripped off the code he uses for those, looks kinda alright, but never used it for anything.
Asteroid Belt Like Ours Spotted Around Another StarThe scientists have not actually seen any asteroids around Zeta Leporis, a young star twice as massive as the Sun and 60 to 70 light-years away. Instead they have studied the temperature and position of the star's swirling mass of debris, which they say shows evidence of chaotic collisions among rocks that creates the dust needed to sustain such a disk... Zeta Leporis, also called HR 1998, is between 50 million and 400 million years old, compared to our middle-aged Sun, which is about 4.5 billion years old. Along with some other young stars, it was found in the 1980s to have a ring of dusty debris. And in 1991 astronomers learned that this debris ring was unusually warm and close to its parent star, unlike other disks that are farther out, and hence colder. This dust, given its known properties, should spiral into a star within 20,000 years, according to current theories of physics and star formation, scientists say. But this star is much older.

A Star Like Our OwnAn asteroid belt may have been found surrounding a star much like our own Sun, according to Dr. Charles Beichman of CIT. His team used NASA's Spitzer Space Telescope to make the discovery. If confirmed, this would be the first asteroid belt detected around a star that is about the same age and size as our Sun. If true, it could offer a rare look at a star system that closely resembles our own... According to the astronomers, it is possible that a giant comet, as big as the planet Pluto, got knocked into the inner solar system and is slowly boiling away, shedding dust in the process. "The 'super comet' theory is more of a long shot," Beichman said, "but we'll know soon enough." Future observations of the star using Spitzer and ground-based telescopes are expected to conclude whether asteroids or comets are the source of the dust.

Artist's conception of the system shows the view from a planet that might exist in the system. Note the asteroid collision in the foreground - this replenishes the dust detected by the Spitzer telescope.

The name X-Planets is a play on the terms "exploding planets", "extrasolar planets", and "Planet X", the last of which has been used by astronomers to designate a hypothetical, undiscovered, or recently discovered planetary body. It isn't intended nor should it be inferred to be a play on the name of that famous TV drama about the FBI agents who investigate every paranormal phenomenon they encounter except for the fact that their cellular phones always work, even under the Antarctic icecap. It makes Gilligan's Island's Professor's coconut-based nuclear reactor look plausible.
That last sentence was just an excuse to use three possessive words in a row. It was fun. The Professor never made a nuclear reactor out of coconuts. And I can't remember if the FBI agents used their cell phones when they went to Antarctica that time.
Giant "starshade" could reveal new exoplanetsAn astrophysicist in the US has devised an unusual way to spot extrasolar planets -- by blocking the light from their parent star with a space-based shield. Webster Cash of the University of Colorado says that a thin, sunflower-shaped plastic screen measuring about 50 metres across could be enough to allow planets as small as the Earth to be observed directly. The big snag is that the shield, dubbed a starshade, would have to be attached to a spacecraft and placed tens of thousands of kilometres away from a space telescope. Cash's design may sound like science fiction, but it has already received a $400,000 funding boost from NASA (Nature 442 51).
