Charting Astronomers

zzzzzzz....

*snort* hrmph! wha? Whozzere? Oh, sorry. I was sleeping for a bit. Sorry about that. It happens from time to time. Usually during a busy/stressful period I tend to let such things as blogs fall into neglect, then drag my feet when it comes to getting them running again.

In any case, what better time to get started than during a rather well publicized space weather storm (though I will get to that eventually.)

First, a rather neat picture I found on Phil Plait's excellent blog that charts astronomers' careers based on publications and "fame" (as calculated by a Google search.)



It is remarkable that, even though he dedicated so much time to public outreach and education, Carl Sagan could still be involved in so much science. Then again, these are not first author papers (as Phil Plait admits to having only two of those), so it is likely that he was put on many either as part of a spacecraft mission PI (primary investigator) or just to beef up paper credentials.

Incidentally, and mostly to satisfy my own curiosity, I would fall in the main career sequence/dark astronomer range with about 15 papers (four first author, one single author- suck it, Plait!) but likely very low on the media impact scale. My name is more common that I would care to admit, so my Google results are quite muddy. Additionally, I am NOT an astronomer, but a space scientist/plasma physicist, so the paper scale may not be weighted equally.

More Scopin' Fun

I've continued to play with the Galileoscope over the weekend. I will say this again, it has been the best $15 I've spent in my life. While I will certainly be looking for a high end 'scope when I can afford it, the Galileoscope does what a good intro telescope should. At both 25x and 50x, you can aim at any dark spot in the sky and see dozens of stars that were not visible with the naked eye. You can clearly see the 4 largest Jovian moons, and I was even able to make out the main cloud bands on Jupiter.

I've made -some- progress on the video capture front. I've given up on using my hand-held digital camera and have decided to try to mount a webcam to the eyepiece (ala Thunderf00t, a man who clearly knows his astronomy.) I was having troubles getting my external webcam to work with my Macbook, but blogger Sidiasus stepped up to the plate and suggested using a memory-stick based Ubuntu Linux distribution. This works great, and has the additional benefit of command-line control over the webcam image. I'll try to test this sometime this week. In the end, the case may be that I will need better equipment to capture some of the images I've witnessed over the past several weeks.

Whiskey Tango Friday

In this inaugural edition of Whiskey Tango Friday (WTF), I present a piece of the internet that I've been meaning to share for a long time.

At last May's AGU meeting, I was perusing the research posters when I ran into one that piqued my interest. I can no longer remember the exact title, but it was something along the lines of how space ions can impact terrestrial weather. Okay, sounds neat, I'll give it a look. It didn't take long for me to realize that the poster didn't make much sense. It asserted that a strong electric field, called the SOLAR CAPACITOR [emphasis not mine] was responsible for ALL weather, especially the scary stuff, such as hurricanes. The author said that comets are the result of this SOLAR CAPACITOR, and astronomers were dumb for calling comets "dirty snowballs" (a gross over-simplification of decades of observations).

After re-reading a few of these points to make sure I wasn't nuts, I realized that the author was a crank. He also had a few self-published books on display, covering topics such as how to use a new form of math (using non-base-10 number systems) to calculate all of the prime numbers and other "science" books with no data, no references, but a lot of hand-drawn pictures that seemed to ignore a lot of physics. The more I reviewed his material, the more I realized he was good at being a crank.

The identity of this man? James McCanney. For this first WTF, I present his website in all of its cranky glory. A few highlights demonstrate that James McCanney is a scientific rebel:
  • Pictures? Paragraphs? Layout? Sentences that end in anything but ellipsis or exclamation points? Screw that! Why water down James McCanney's message of truth? Take THAT, grammar!
  • A link to a page where he's selling Doulton (?) personal water filters. Take THAT, fluoridation!
  • An opening statement (buried in a link 1/3 down the page) that explains how astronomy relies on four incorrect axioms- axioms that, if exposed, will bring down our astronomer overlords! These four lies have been taught to every astronomy PhD student since the 50's, rendering those degrees useless! Take THAT, astronomers!
  • Note that James McCanney doesn't have a PhD, just a masters degree. Not because he wasn't good enough, but because he was TOO SMART to be tricked by said axioms. Take THAT, establishment!
  • After all of his theories, rants, and links to his books, there is a small section called "about conspiracy theories." It reads, " ... occasionally i hear someone say this page contains "conspiracy theories" ... that term was created by a government think tank back in the 60's to de-rate and ridicule anything not broadcast by the official news media on the evening news[.]" That's right, he just conspiracy-theoried away conspiracy-theories. Take THAT, rational thought!
Some day I'll have to work through his space weather section and show why it's just plain wrong. It would be horribly unfair of me to pick on his work without saying why it's wrong. But alas, such is not the goal of WTF. I just have time to bring such oddities to light.

As Advertised.

The Galileoscope came out again last night. It was not the best night for observing, however- nearly full moon washed out many objects, and there was a bit of cloud cover that cut the night short. Despite this, for the first time I found Jupiter! Sure enough, just as claimed, I was able to see 4-5 moons. It was incredible. I could not see the cloud bands, and the Jovian moons were just specs, but I was excited none the less.

As I admitted to a good friend of mine, astronomy is NOT a strong point of mine, so I had to use a nifty iPhone/iPod touch app to help me find things (Planets by Dana Peters - free and recommended.)

I am trying to jury rig a camera to the 'scope to get some images here, but it hasn't gone well so far. I'll try a few new things tonight.

Telescoping

Tonight was the second night that I was able to take out my "Galileoscope" and take a look at the moon. I have a shameful confession to make- not only is this my first telescope, it is also my first time outside of an undergrad intro to astronomy class that I've spent some quality time looking at the night sky. Pretty bad for a space scientist...

Anyhow, the 'scope is everything for which I had hoped. At 25x and 50x, the moon was amazing. Many of the smaller craters are easily visible, as well as the rays coming off of the larger ones. The detail is stunning and inspiring. The challenges with the smaller scope are focusing (performed by pushing/pulling/twisting the inner tube in and out of the larger one) and keeping the scope steady on a cheap camera tripod.

Tonight, feeling a bit more confident with my ability to find objects in the sky, I turned toward some of the brighter stars. Although I couldn't line them up, I was amazed at the number of stars that I could see through the 'scope in areas that appeared empty with the naked eye. I was taken aback by the thought that in each empty space I could see with the telescope, there were an infinite number of objects waiting to be seen. Of course this should be obvious, but until you finally look yourself, it is hard to fathom.

This is the best fifteen bucks I've spent in a long, long time.

HUZZAH!

I've taken a short vacation, hence the lag in posts lately. However, I do have plenty to talk about.

The first item is the arrival of my Galileoscope last Friday!

Some assembly required, eh? Wasn't too bad, however, and soon I was spying on the neighbors looking at the night sky.

Unfortunately, the moon hasn't been out early enough to test the 'scope yet. Being a cheap instrument on a cheaper tripod, I had a lot of trouble getting stars into focus as well. Additionally, this is my first telescope, so I'm still learning how to use it properly. At this point, I'm waiting for the next night where I can get a good, clear shot at the moon. This will make for a much easier time getting objects in focus.
