Tom, if your students are in ABQ, it might be convenient for them to go to
the UNM Campus Observatory. Nearly every Friday night while UNM is in
session, the UNM astronomy students open up the dome to the public for free
viewing, plus there are amateur astronomers from the ABQ club there who set
up a variety of telescopes next to the observatory. Here's the hot line to
call on Fridays to find out if they're open that night: (505) 277-1446.
The ABQ club also does free stargazing events in the Manzano Mountains at
Oak Flat Picnic Area. The last date for 2009 is Saturday, September 12.
Starts at sunset. Directions at:
http://home.comcast.net/~friesend/abqsky21dec/oakflatdirections.pdf
I can't speak to the Etscorn event schedule, but I do know the big event
there is the Enchanted Skies Star Party. There's a modest charge for that
multiple-day event. I went last year and really enjoyed it. Here's that
website: http://enchantedskies.org/
Finally, there is a public astronomy program at Bosque del Apache on October
10 at 7 p.m. It's called "A Scavenger Hunt in the Night Sky." That's all I
know. If I get more info, I'll pass it along on the listserv.
Happy gazing!

As a little kid,
I wanted to cruise the galaxy looking for weird life forms…the more
tentacles, the better. Alas, there has been the small matter of
inadequate transportation so far to accomplish this childhood aspiration.
Instead, I have turned my eyes inwards to our planet to seek out life wherever
it is living on the edge. Extreme temperatures, darkness, radical
chemistry, no nutrients, heavy metals, ionizing radiation, being trapped for
millennia within crystals…whatever would kill a more conventional example
of Earth life is greeted with glee by my little pets. At the dawn of our
understanding of exoplanets around other stars, we can begin to compare what we
know about extreme life on our planet with what we might find in our Solar
System and far beyond. The beginning of truly Comparative Astrobiology is
now upon us. Join me for a guided tour of the micro-aliens here on Earth,
and speculate with me about life on Mars, Europa, Titan, Enceladus and good old

Save our dark skies, say scientists
Access to a dark night sky is a basic human right that needs to be
protected, a meeting of the world's professional astronomers has
decreed. The International Astronomical Union passed a resolution
calling on governments to give priority to safeguarding areas that allow
observation of the stars. Scientists at the two-yearly gathering of
space scientists, held this month in Brazil, warned that the light
pollution went beyond the issue of studying the universe.

July 20, 2009 | 9 comments\ Did a Comet Cause a North American Die-Off around 13,000 Years Ago? Tiny hexagonal diamonds suggest a massive impact during the late Pleistocene that could have wiped out the Clovis people, mastodons and other continental inhabitants -- but the geologic evidence falls short for some skeptics By Brendan Borrell
COMET CLASH: James Kennett [left] and son Doug on Santa Rosa Island in California where they discovered more evidence that a comet caused an extinction event 13,000 years ago. UC SANTA BARBARA [ http://www.pnas.org/content/early/2009/07/17/0906374106.abstract ]
Researchers have found shock-synthesized hexagonal diamonds on one of California's Channel Islands, which they say is the strongest evidence yet that a comet exploded in the atmosphere above North America, causing widespread extinctions there around 12,900 years ago. Skeptics, however, say the debate is far from over.
In 2007 researchers theorized that a comet set off continental fires that led to the mysterious disappearance of the Clovis people and the extermination of 35 mammal genera, including mammoths, mastodons, ground sloths and camels. The team documented a "black mat" of charcoal throughout North America that contains high levels of iridium, magnetic spheres, and nano-diamonds, which are consistent with such an airburst. The controversial theory also gibes with the 1908 Tunguska atmospheric detonation (also thought to be from a comet or meteorite) that leveled trees in Siberia, and it echoes the extraterrestrial impact widely believed to have wiped out the dinosaurs 65 million years ago.
Today, in Proceedings of the National Academy of Sciences, the same team reports on shock-synthesized hexagonal diamonds, known only from meteorite and other impact events, in a soot layer from Arlington Canyon on Santa Rosa Island in California. The canyon is famous for containing the earliest human remains in North America, dating back to 13,000 years, and the soot layer coincides with the disappearance of the pygmy mammoth from the island. In a documentary shown earlier this year on the Public Broadcasting Service's NOVA science show, the team also claimed that they discovered similar diamonds from the Greenland Ice Sheet dating to the same period.
But the evidence does not convince everyone. "I don't think much of this whole story," says geochemist Christian Koeberl of the University of Vienna in Austria, "Diamonds of any sort are not uniquely characteristic of impact events." He says that the major lines of evidence are still missing, including the presence of shocked minerals, including breccias and tektites as well as an impact crater. "At least three other groups searched for similar evidence in the same or similar samples and found none," he adds.
Briggs Buchanan, an archaeologist from Simon Fraser University in Burnaby, British Columbia, disputes the notion that humans declined following the purported impact. "We have shown that in California, specifically, that there [was] no severe decline in the resident population." He adds that other researchers have shown that the black mat varies in age across the continent and appears to have a variety of geologic origins.
What does the research team have to say about their doubters? "I'm so skeptical about the skeptics," says marine geologist James Kennett of the University of California, Santa Barbara. "We work in a different paradigm where different materials result from different kinds of impacts."

selrachj at 06:44 PM on 07/21/09 Great new theory that fits a lot of facts and the skeptics seem a bit threatened. For example, one says that he has shown that the human population of California did not experience a decline in population when, in fact, no one really knows much about populations in California at 13,000 years ago. This seems like it will probably replace the competing megafaunal extinction theories - overhunting, disease, and climate change --- unless we want to consider it one hell of a change in the climate.
rwilliston at 09:41 AM on 07/22/09 Wouldn't it be much more probable that the decline in large species is a result of the growing human population? Wherever else humans have been introduced, there have been mass extinctions of species that couldn't adapt. I think there is a lot of traction on this theory, so to just dismiss objections as the work of "skeptics" is a bit premature.
cwpaisley at 12:23 PM on 07/22/09 I enjoy keeping an open mind (or eye) on past events. I believe that is how we discover things.
robert schmidt at 10:22 PM on 07/22/09 The following is a direct response to this comment. rwilliston, a hypothesis doesn't become a theory simply based on something similar happening someplace else. There needs to be proof. There is no such thing as a "default" theory. We don't just believe something to be true until someone proves otherwise. There are a great deal of unanswered questions regarding an anthropomorphic cause to the North American Mega Fauna Extinction. I somehow doubt that a handful of stone age wonderers wiped-out all the mega fauna of North America shortly after arriving. There weren't that many of us and we weren't that great at bringing down the big animals. Ultimately, let the best hypothesis win, and by best I mean most consistent with existing evidence.
By the way; I don't know why the term "sceptic" is such a bad thing. Scepticism is not only a good thing; it is essential to good science. Only once a hypothesis has past the scrutiny of informed scepticism can we feel confident that we are on the right track. If only more people were sceptical about what they read or heard we would have a much more enlightened population and fewer tabloids, fewer republican presidencies and certainly no Fox News! The hypothesis you should be most sceptical about is the one you find easiest to believe.
Quinn the Eskimo at 11:17 PM on 07/22/09 @ robert schmidt: Now now, there. Take an aspirin and get a good nights sleep. You were doing all good and stuff until you went all political our science butts.
This post throughly presents mainstream research, worthy media accounts, and valuable links for open-minded exploration.
To illustrate, I herein quote the whole abstracts for the Richard B. Firestone et al seminal report and a C. Vance Haynes, Jr. review.
As well as evidence for the probable time and cause of the extinction of Clovis culture in the Americas, many sites are also in Europe.
The connection with Carolina Bays confirms a continental disaster, which may have retarded the evolution of urban culture in the Americas, despite generally favorable landscape, climate, water, and lack of large competing mammals.
As a conscientious scientific amateur, I want to open up evidence and reason based dialogue re evidence I readily found for widespread fields of very similar craters in the Northern Hemisphere, starting with a specific, convenient, accessible crater near Las Vegas, New Mexico.
Others can join in quickly locating similar fields in almost every state.
There is opportunity for amateurs to make very helpful contributions in exploring multiple research opportunities.
eminence grise at 10:39 AM on 07/23/09 The following is a direct response to this comment. Quinn: First, I want to say that I agree with Robert Schmidt's comment on hypotheses and skepticism. Second, I want to say I agree with yours also. In the next few months we will see the extinction of the U.S. middle class, a man-made catastrophe visited on us by Republicans and Democrats who are supposed to represent us but are actually in the pockets of the big global corporations. Third, I want to go on record as believing that a comet took out the North American megafauna, and the Clovis culture along with them.
eminence grise at 11:05 AM on 07/23/09 The following is a direct response to this comment. Rich: I was unable to access either of the links that you give at the top, but I did look at the Google Map view of the Carolina Bays near Las Vegas New Mexico. Very impressive, but I have two questions. How can you be sure that some or all of these features aren't volcanic, and how can you be sure of these features' ages? I suspect that the second question could be answered by getting someone to determine cosmic-ray exposure ages of the sandstone outcrops exposed inside the bays.
Otherwise, I'm kind of pushing the impact-origin hypothesis for the original Carolina Bays of N Carolina and Virginia: http://impactglassheretic.blogspot.com/
rmforall at 09:33 AM on 07/24/09 Eminence Grise: These kind of fields of round, oval, and irregular shallow craters, sometimes in durable bedrock, usually without connected drainage, with a fractal distribution of sizes, are simply too common to be volcanic in general -- take a look on Google Earth or Maps at the region about 40 miles from Amarillo to its southeast. With Google Maps set to Terrain, many of these 0.1 to 10 km features will show up a blue lakes, making it easy to find clusters. Where there are big craters, there are small ones.
Start from Las Vegas, NM and follow 104 east 20 miles to take the NE fork of CR CR53A -- in a mile, directly on the left, is the NS crater that I have walked directly, a mile long and 0.2 mile wide, showing the horizontal red sandstone beds on its rim, especially on the west, and a flat bottom. The rim is not raised. There are two parallel small ridges in the lower center, with a muddy cow wallow between. The south end of the crater is by a small road quarry about 200 feet wide and 16 feet deep of white mineral material, common in the region, completely distinct from the typical red sandstone bedrock. The west rim shows progressive color changes and disruption as I walk along it by to and by the center, including 6 foot chunks tossed over in place, looking to my amateur eyes obviously scorched. Fragments up to 3 foot size abound in and around the crater.
I imagine that the explosion was on the surface, not buried as in typical iron or stone meteors. There is no sign of shocked or vaporized material, so it seems the impact was about 5 km/sec, from a low-impact angle for an mostly ice object falling out of a low orbital trajectory, with enough energy to create a superheated steam explosion, dispersing the surface rock, and depositing its mineral contents as the white deposits locally, which, being water based, would easily moved about by subsequent erosion by water and wind. The minor degree of erosion indicates a recent Holocene age.
Very similar is McAllister Lake, in a federal wild bird park, 8 miles SE of Las Vegas, NM, and Crane Lake just to its NE.
This overall pattern shows up everywhere. I suggest you survey your own region with Google Maps, or give me the location, so I can scout out some prospects.

sinkholes? Davias & Gilbride re Holocene ice comet fragment impacts
worldwide: Re: [NM Astronomy] Re: widespread Carolina Bay type craters: Pat
O'Connell: Rich Murray 2009.06.15
2009.06.15 Hi Pat, Thanks for your cogent suggestion.
The specific crater I cite shows convincing evidence of shattered and
blasted red sandstone bedrock on the west rim by the deepest part of the
elongated roughly north-south crater. There are chunks of the red sandstone
up to 1 m size scattered about within a mile or so.
Impacts will fracture bedrock, facilitating the evolution of ponds, springs,
sinkholes, and caves. Such thicks layers of horizontal fractured bedrock
are common in many places in roadcuts along I-25 from Santa Fe to Las Vegas,
New Mexico.
Mostly ice meteors at relatively low velocity impacts will generate high
temperature, high pressure steam explosions that will excavate craters
without creating much melting or vaporization of the ground rock or leaving
the kind of rocks and metals that are usually signatures of meteor impacts.
Last week I found a brother-sister team of scientific amateurs that have
located similar features all over the world, and offer a unified
interpretation, explained in a very long website with over a hundred Google
Earth images, namely, that sometimes huge, mostly ice meteors bearing a lot
of white silica sand have had 6-8 km/sec impacts at as little as 5 degrees
angle to the ground, producing ejecta that in turn produce characteristic
craters and mounds at various distances downrange, during the past 15,000
years:

My other hobby besides astronomy is caving and cave science.
While I haven't checked out the area you're talking about, consider that there
is a large gypsum karst area running through the eastern edge of the state.
There, sinkholes are created by water running through cracks in limestone and
sandstone, that undermine the upper layers and cause sinkholes. The aerial
photos may well be impacts, but I think sinkholes are more likely.

NIGHT SKY OBSERVING AT CHACO
CULTURE NATIONAL HISTORICAL PARK
The Albuquerque Astronomical Society (TAAS) and the National
Park Service will co-host evenings of free public stargazing at Chaco
Observatory on May 23, and September 19, 2009. The dark skies of the park and
the instruments at the observatory together provide great views of planets as
well as deep sky objects such as galaxies, nebulae, and star clusters. The park
also hosts evening observing programs on Tuesdays, Thursdays, and Saturdays
from April thru October. Observing begins at 8 p.m., weather permitting, and is
suitable for all ages. Park rangers give presentations about the archaeoastronomy
of the Chaco culture. Admission to the park
costs $8 per car load. There is no additional fee for admission to the evening
observing programs.
The park is located in Northwestern New
Mexico. The recommended access route to the park is from the North,
via US 550 (formerly NM 44) and County Road (CR) 7900, and CR 7950. From the North,
turn from US 550 at CR 7900--3 miles southeast of Nageezi and approximately 50
miles west of Cuba
(at mile 112.5). This route is clearly signed from US 550 to the park boundary
(21 miles). The route includes 8 miles of paved road (CR 7900) and 13 miles of
uneven dirt road (CR7950). For more information, visit the Chaco Culture
National Historical Park (CCNHP) website at http://www.nps.gov/chcu
or call the CCNHP at (505) 786-7014. You may search the website for
“night sky” to find additional information about the night sky
program at CCNHP.
EXPLORA ADULT NIGHT
Friday, May 15, from 6:30 to 10 p.m., is Adult Night at the ExploraScienceCenter in Albuquerque,
across from TiguexPark. Peer through the
telescopes that will be setup, weather permitting, on the West deck. Perhaps
you will see Saturn, which is currently in the constellation, Leo. To obtain a
map to the park, visit http://www.cabq.gov. For

STARGAZING IN THE MANZANOMOUNTAINS
The Albuquerque Astronomical Society (TAAS) and the Sandia
Ranger District will co-host an evening of free public stargazing in the ManzanoMountains on Saturday, May 30, at Oak
Flat. Other 2009 event dates in this popular Saturday evening stargazing series
are June 27, July 25, August 15, and September 12. The dark skies of the EastMountains
and the large telescopes of TAAS astronomers together provide great views of
planets, as well as deep sky objects such as galaxies, nebulae, and star
clusters. Observing begins at sunset, weather permitting, and is suitable for
all ages. Picnic facilities are available for those who would like to come
early, and adjacent parking is available. Alcoholic beverages and pets are not
allowed in the telescope viewing area. To get there, take NM Highway 337 nine
miles south of the Tijeras exit on I-40, and follow the signs to Oak Flat and
Juniper Loop. For information, visit http://www.taas.org or call
505-254-TAAS.
St. Helena, Edmond
Halley, Stellar Proper Motion, and the Mystery of Aldebaran
Dr. John C. Brandt will discuss
Edmond Halley’s discovery of stellar proper motion at the next
general meeting of The Albuquerque Astronomical Society. The meeting will take
place at 7 p.m. on Saturday, April 4, and it will be held in Regener Hall on
the University of
New Mexico Albuquerque Campus.
For information, call 505-254-TAAS. Visit the http://www.taas.org
Web site to obtain a map. Below is a summary of the discussion:
Edmond Halley announced his
discovery of stellar proper motion in Philosophical
Transactions in 1717. My interest in Halley’s work in stellar
astronomy was stimulated by a day spent on the Island
of St. Helena
in November 2006. I was able to visit the site of Halley’s observatory.
The talk will begin with a brief overview of this fascinating island and some
of its history, including Napoleon’s incarceration. Halley chose the
island to carry out observations for his famous catalog of the southern sky.
This work apparently led him to believe that some star positions had changed
since ancient times.

Hello friends of the New Mexico night sky,
Tomorrow, Tuesday afternoon beginning at 1:30PM, the House Business and
Industry Committee will meet and has HB 362a on the agenda.
If you haven't already done so, now is the time to contact your
representative and let them know you support passage of HB 362a. Even
better than calling would be to attend the hearing in person. Having
supporters in the room makes an impression on legislators.
Please forward this information to anyone you know who is supportive of
protecting and preserving the aesthetic, cultural and scientific value
of New Mexico's night sky.
Please contact the Representative from your district and let them know
you support House Bill 362a.

THE UNM SEVILLETA Field Station will host two weekend workshops in
recreational astronomy during 2009, the International Year of Astronomy.
The field station is located on the Sevilleta National Wildlife Refuge
in
Socorro County. The first workshop will be held in late-April, but early
signup is encouraged. Space is limited to 20 participants.

Friends, colleagues, astronomy enthusiasts, and IYA 2009 advocates:
Judy Stanley, education officer for the Very Large Array, and I, in partnership with Don Natvig, director of the UNM Sevilleta Field Station, are launching STAR-HOPPERS, a not-for-profit program that offers weekend workshops in astronomy for beginners. The workshops will be held at the Field Station, which is on the Sevilleta National Wildlife Refuge.
We're offering two workshops during the International Year of Astronomy. Our spring workshop for adults is scheduled for April, and our fall workshop for grandparents & grandkids is slated for September. If all goes well, we hope to expand the program next year.
Please visit our website at www.astronomyworkshops.org for all the details. And please forward this email to anyone in your networks who might be interested. Thank you!
I am writing to request your action on House Bill 362 - Mandatory
Night Sky Protection Act Enforcement. Two years ago, your invaluable
support helped move a similar bill out of the Senate with a vote of
32-3 and into the House committees where it passed its first hurdle,
but the session expired before it could be heard by its final committee.
This time, I expect a companion bill to be introduced on the Senate
side to streamline the process. As soon as I get more information I
will pass it along.
HB 362 is likely to be heard by the House Energy & Natural Resources
Committee as early as this Friday morning, February 13th.
If you are local to Santa Fe and can possibly attend the hearing,
please come. Legislators are impressed by a room full of supporters.
To check the latest status on the committee calendar you can visit.

displayed to read about upcoming sessions.
If you can't attend personally, please use the listing below to find
the Representative for your district and call the capitol office to
urge their support for HB 362.

The Albuquerque Open Space Division will host the next
International Year of Astronomy event, Hearts, Stars, and Telescopes, at the OpenSpaceVisitorCenter
on Saturday, February 14, 2009. Observing will occur from 18:30 until 22:00
hours. Details are at the http://www.ABQSky.org
Web site, which is also accessible from The Albuquerque Astronomical Society Web
site, http://www.taas.org. There will be
comet making demonstrations, telescopes setup, night sky observing, and hourly tours
of the stellar constellations. The Open Space Visitors’ Center is located
east of Coors Blvd.,
at the end of Bosque Meadows Rd., which is between Montano Blvd. and Paseo Del Norte.
Venus is currently in a crescent phase and is visible to the
naked eye in the early evening in the southwest part of the sky. Saturn is in
the constellation, Leo, and over the next several months, the planet’s
rings will appear to become thinner as seen from Earth.

The 5 closeups are about 2.2x2.2 arc-seconds wide and high, about
70x70 pixels.
The HUDF is 315x315 arc-seconds, with N at top and E at left.
Each side has 10,500x10,500 pixels at 0.03 arc-second per pixel.

image of 3022x2496 pixels, which can be also be conveniently seen
directly at their Zoomable image:
www.spacetelescope.org/images/html/zoomable/heic0714a.html
Notable in the deep background of the five closeups are ubiquitous
bright blue sources, presumably extremely hot ultraviolet before
redshifting, 1 to a dozen or so pixels, as single or short lines of
spots, and a few irregular tiny blobs, probably, as predicted in many
recent simulations, the earliest massive, short-lived hypernovae, GRBs
with jets at various angles to our line of sight, expanding bubbles,
earliest molecular and dust clouds with light echoes and bursts of
star formation, and first small dwarf galaxies, always associated with
a subtle darker 3D random fractal mesh of filaments of H and He atomic
gases.
As a scientific layman, I am grateful for specific cogent, civil
feedback, based on the details readily visible in images in the public
