A Wrinkle in Space-Time
By Trudy E Bell
When a massive star reaches the end of its life, it can explode into a supernova rivaling the brilliance of an entire galaxy. What’s left of the star fades in
weeks, but its outer layers expand through space as a turbulent cloud of
gases. Astronomers see beautiful remnants from past supernovas all around
the sky, one of the most famous being the Crab Nebula in Taurus.
When a star throws off nine-tenths of its mass in a supernova, however, it
also throws off nine-tenths of its gravitational field.
Astronomers see the light from supernovas. Can they also somehow sense
the sudden and dramatic change in the exploding star’s gravitational field?
Yes, they believe they can. According to Einstein’s general theory of relativity, changes in the star’s gravitational field should propagate outward, just
like light—indeed, at the speed of light.
Those propagating changes would be a gravitational wave.
Einstein said what we feel as a gravitational field arises from the fact that
huge masses curve space and time. The more massive an object, the more
it bends the three dimensions of space and the fourth dimension of time.
And if a massive object’s gravitational field changes suddenly—say, when a
star explodes—it should kink or wrinkle the very geometry of space-time.
Moreover, that wrinkle should propagate outward like ripples radiating outward in a pond from a thrown stone.
The frequency and timing of gravitational waves should reveal what’s happening deep inside a supernova, in contrast to light, which is radiated from
the surface. Thus, gravitational waves allow astronomers to peer inside the
universe’s most violent events—like doctors peer at patients’ internal organs
using CAT scans. The technique is not limited to supernovas: colliding neutron stars, black holes and other exotic objects may be revealed, too.
NASA and the European Space Agency are now building prototype equipment for the first space experiment to measure gravitational waves: the Laser Interferometer Space Antenna, or LISA.
LISA will look for patterns of compression and stretching in space-time that
signal the passage of a gravitational wave. Three small spacecraft will fly in
a triangular formation behind the Earth, each beaming a laser at the other
two, continuously measuring their mutual separation. Although the three
Page 4
NORTH STAR
‘craft will be 5 million kilometers apart, they will monitor their separation to one
billionth of a centimeter, smaller than an atom’s diameter, which is the kind of precision needed to sense these elusive waves.
LISA is slated for launch around 2015.
To learn more about LISA, go to http://lisa.jpl.nasa.gov. Kids can learn about
LISA and do a gravitational wave interactive crossword at http://
spaceplace.nasa.gov/en/kids/lisaxword/lisaxword.shtml.
Caption:
LISA’s three spacecraft will be positioned at the corners of a triangle 5
million kilometers on a side and will be able to detect gravitational wave
induced changes in their separation distance of as little as one billionth of
a centimeter.

Send Your Memories to Lorrie
By Sue Wheatley
Some events on Earth produce vivid memories. These events always spark the “I
remember where I was when….”
Some of these are Earthly memories.
• I have a friend who remembers his father taking him to see the Hindenburg
land, but then for some reason that puzzled him as a little boy, his father
whisked him home before he saw it.
• My father could recount where he was and what he was doing the instant he
heard about Pearl Harbor.
• I can remember where I was and what I was doing when President Kennedy
was shot.
• 9/11 is the same for all of us.
But as astronomers we have a parallel set of Universe memories.
• I remember where I was when I first saw M 13. I was 13.I was lying on my back
on a pier in Wisconsin with a pair of binoculars. I was all alone, and I wanted so
badly to show whatever that was in the sky to someone.
• I remember setting my scope up on the driveway to see Haley’s comet. I remember who came driving slowly down the street to see it, their car lights out
so they wouldn’t disturb me.
• I remember Roger and I being approached cautiously by a squad car on Kauai.
(Someone had reported suspicious activity in the cane field.)
• I remember an observer next to me talking one dark night about “Mu” Ceti. An
instant later a very loud and very close “Mooo” came from a stealth-footed cow.
This was followed by astronomers scattering every which way.
• I remember standing in a Beaumont field watching the fire streaming from horizon to horizon as the shuttle came in for a landing in Florida. I remember being
able to see the nose and tiny wings at the front of the fire.
• I remember where I was when I saw Jupiter get hit by Comet Shoemaker-Levy.
• Likewise when Comet Hyakutake was just outside the back door.
• I remember saying goodbye to MIR as it passed for the last time overhead.
• We all remember where we were and what we were doing when Challenger
exploded.
• Likewise for Columbia.
There are memories that all of us saw, and there are those that only some of us
saw.
Whatever they are, I bet you have a set of your own special memories. You can
remember where you were and who was with you, can’t you? How many special
memories do you have? 5? 10? A dozen?
Note from Editor: I encourage you to send any interesting experiences you may
have had. Email your article(s) to the email address on page 19.

Book Review: Astronomy Hacks
By Aaron B. Clevenson, ALCor
You hear people talk about the brightness of an object, sometimes they talk
about magnitude, and sometimes they talk about surface brightness.
What's the difference? You want to "run" a Messier Marathon. Where do
you go to find information about the timing and the order you should observe the 110 objects? You are having problems with stray light at your
dark site, and it is interfering with your dark adaptation. What can you do to
"take back the night" and keep your ears warm at the same time? The answers to these questions and 62 more can be found in a new book entitled
Astronomy Hacks:
Tips and Tools for Observing the Night Sky by Robert Bruce Thompson and
Barbara Fritchman Thompson, published in June 2005 by O'Reilly Media,
Inc.
This book is a wonderful collection of suggestions and ideas to make an
astronomical observing session more productive, more comfortable, and
more enjoyable. The "hacks" are organized into four chapters: Getting
Started, Observing Hacks, Scope Hacks, and Accessory Hacks. There is
something for everyone, and there are all kinds of things that you may
never have thought of doing.
Anyone who has spent any time observing, especially in groups, has heard
little snippets of wisdom from their fellow astronomers. You hear lots of little
ideas that make life at the eyepiece much more fruitful. It may be something as simple as the value of having a Unit Power Finder (Hack # 53)
such as a Telrad, or as important as the proper way to clean your optics
(Hacks #34 and #52). But did you know that when you are comfortably
seated at your eyepiece (instead of standing) you improve your performance by an amount that is the same as having a telescope up to 2 inches
bigger (Hack #60)? Or do you know how to make a film canister collimating
tool (Hack #37)?
The authors, long-time amateur astronomers, have collected these kernels
of wisdom, and to our benefit, have put them in one place where those of us
who could benefit from that wisdom can easily access it. The book makes
for a fun and interesting read. And one or two useful "hacks" make the
book well worth the price. Happy and Fruitful Observing!

Only 85 Observers in the World?
By Sue Wheatley
At the 2005 AL convention, Don Parker gave some statistics
that caught my attention.
• Only 85 observers in the world watch Mars on a regular basis.
• The polar cap of Mars is not centered on its pole, but is off
center.
• The surface brightness of Mars is more than Jupiter’s.
• You can get a decent photo of Mars at 1/25 to 1/30 sec. A
blue filter or red filter (used for seeing dust storms) bumps
this up to 1.5 seconds.
• Deneb is the pole star for Mars.
• Because Mars rotation is 10 ° different per day than Earth’s,
we see the same spot on Mars facing us every 36 days.
• The polar cap of Mars is formed when the cloud ice above
the pole condenses in almost an instant and settles on the
planet. (No slowly falling snow here.)
I can’t show you the slides Don presented, but he said that the
seemingly most crude sketches from observers often provide
much better information than the glossy photographs done so
infrequently. As an example, he showed a sketch, timed and
dated by the observer, that showed the very first indication of a
major Mars storm that engulfed the planet for months. No professional scope was even aimed at Mars when it began, although dozens of professional followed the storm once they
knew it was beginning.
So the plea is: Sketch Mars whenever you can. Note the time
and date, and send your sketches to the Mars section of
A.L.P.O.
And the quote of the day: Niels Bohr “An expert is a man who
has made all the mistakes in a very narrow field.”

I Think I Touched a Page That Galileo Touched!
By Sue Wheatley
Make a special trip to Kansas City, MO. It is worth it. During the 2005 Astronomical League convention there, Roger and I had a special treat.
Bruce Bradley, the curator of the Linda Hall Library, offered us a tour of the
library’s rare astronomy book collection. This is not a collection under
glass, but books that you can handle, turn pages, and be totally overawed
by.
For example, imagine turning the pages of Galileo Galilei’s Sidereus nuncius, published in Venice in 1610, or imagine leafing through Nicholaus Copernicus’s De revolutionibus orbium coelestium, published in Nuremberg in
1543.
Bradley also treated us to Tycho Brahe’s Astronomicall Coniectur [a new
star] published in 1632, and a student admirer’s rendition of Ptolemy’s Almagestu(m), published in 1515.
Roger was able to run his fingers over the calculations in Isaac Newton’s
first edition of Philosophiae naturalis principia mathematica, published in
London in 1687.
The library also has Kepler’s 1606 edition of De Stella Nova…, and Rheticus’s Narratio Prima, published in 1540.
We turned the pages of Hyginus’s 1482 Poeticon Astronomicon.
Bradley gave us little known bits of information on each book, such as “This
copy is missing one little piece of artwork. Someone has printed the missing
artwork and just slipped it in between the pages. We don’t know who left it
out, or who printed the little extra piece but didn’t glue it in.” Or, “This book
has 5 pages of corrections which the author has inserted at the back. Later
editions have the corrections included in the text.” Or, “Galileo had the artist insert the faces of the most influential politicians into the angels overseeing the chart of the heavens.”
Roger and I staggered out of the library after two hours. We barely said a
word during the next two hours. We couldn’t believe we had had this rare
experience. We will be forever grateful to Bruce and the Linda Hall library
for this experience.

Trivia Answer
This is the basis of a common myth about meteorites. The answer is "not very hot". The reason is that although they get
very hot when they enter the atmosphere, by the time they
reach the ground they have cooled off significantly. There
have been reports of slightly warm stony meteorites, and iron
ones that were too hot to touch. Those made of stone don't
conduct heat very well, so the heat of entry stays on the surface and it cools off very rapidly. Those of iron conduct heat
very well, but even though they may be heated to the core,
they cool off rather rapidly for the same reason. Bottom line?
There are no smoking meteorites here!
HAS 50th Anniversary Picnic
January 21, 2006
(Event Chairman: If you are planning to attend, please RSVP to your club
contact. See the list below)
10/16/2005 - Menu update. In place of hamburgers and hot dogs, we figured that chili and beef stew would be better for this time of year.
50 years ago in September, 1955, the Houston Astronomical Society
(HAS) was formed. The Society has done many new things over the years.
One of the major accomplishments since the founding of the Society was
the building of our Columbus Observatory. The land surveying started in
1979, and in 1982 the current observatory building was dedicated. Three
years later a time capsule was placed in the ground on the south side of the
building.
On Saturday, January 21, 2006 (with a rain date of January 28th), we will
have our annual picnic (the Fall Picnic was postponed due to Hurricane
Rita). At the picnic we will unearth and open the capsule. And to help celebrate our 50th anniversary we are inviting all the area clubs to attend our
picnic. As usual, the HAS will supply the food for the picnic, including chili,
beef stew and sides, you bring the drinks. We will also have the observatory
open for our visitors, a constellation tour at twilight, and the usual observing
session when it gets dark. Bring your own telescope to test our night skies.
Page 14
NORTH STAR
There will be a "light window" around midnight that if you would like to leave
you may, or you can spend the night at the site if you wish.
Here is the planned schedule of activities:
Gates open 10AM on Saturday
Unearthing of time capsule at 2PM
Dinner served at 4PM
Observing when it gets dark: Sunset 05:57p, Twilight ends 07:18p
Gates close Noon on Sunday
We will need an RSVP by September 10th if you are planning to attend.
Please let your club contact know how many adults and children will be
coming.

RV Information. You may bring your RV / trailer / 5th wheel to the site.
However, we do not have enough utilities for power, water and dump to
support everyone. So if you plan to come to the site be prepared to dry
camp (we do have a dump station if you want to dump before leaving). As
an alternative, there is an RV park on I-10 at Hatterman Lane, which is the
exit to get to the site. From there it is about a 15 minute drive to our site. If
you are interested in staying at the RV park, here is their contact info: Motorcoach RV Park, 2965 Hwy. 90, Weimar, TX 78962, 979-732-9494,

Motel Information: There are several motels in Columbus if you want to
spend the night or part of the next day before going back home.
Watch for details in the coming months. Mark you calendar now for January
21st.
