I’ve Moved!
November 20, 2008
So I’m sure that most people have noticed that the site has been offline for a few days. There’s a reason for that, which I will get to shortly. But first, let me just say this:
In fact, I am blogging at a new site I have just finished setting up: kennethhynek.net. A full explanation for the reasons behind the move can be found here
.
That said, this is not the end of Time Immortal. My wife Grace has expressed interest in taking over blogging at this domain, and I am working to make sure that she gets set up here as soon as possible.
Also, my profound apologies for the modification to the site face; the move was not as seamless as I would have hoped, and many of the image files for this theme, and in the gallery, were corrupted during the course of their evacuation from my previous web host’s servers. Until such time as I have repaired them, I’ve put a clean-looking template in place of the previous one.
Update: for the purposes of further traffic shaping, new posts from kennethhynek.net will be excerpted below. Full articles can be read at the new blog.
Snapshot of an extrasolar planet
September 16, 2008
[image:7520:c:s=1:l=x]Or: a Toronto-based research team has taken what they think might be the first picture of a planet in orbit around a star other than our own.
After years of searching, astronomers may finally have recorded the first image of a planet orbiting a sunlike star beyond the solar system. The body, about eight times Jupiter’s mass, lies exceptionally far from its presumed parent star — roughly 11 times Neptune’s average distance from the sun.
“If this object is a planet at such a wide separation it would challenge our conceptions of planet and companion formation,” says theorist Adam Burrows of Princeton University.
In an article posted online September 10, codiscoverers David Lafrenière, Ray Jayawardhana and Marten H. van Kerkwijk of the University of Toronto caution there’s a small chance that the object, small enough to be classified as a planet, merely resides in the same part of the sky as the star but is not gravitationally bound to it.
But if the body does turn out to orbit the young sunlike star, which has the unwieldy name 1RXS J160929.1-210524, it could pose a problem for planet formation theories. A widely accepted model suggests that the planet-forming disks of gas, dust and ice that surround newborn stars concentrate most of their material close to their stars.
We ask the heavens, and the heavens teach us. I seem to recall reading a similar sentiment in Job 12, recently.
At any rate, this is a fascinating discovery. But then, I was always a sucker for astronomy. It is among my regrets that I will pass away without ever setting foot on the surface of another celestial body.
