After a five year hiatus out of high school, having spent a year in the military, only to be left back where I started… I’m finally getting back into school.  I’ve enrolled in the nearest community college, in order to get my foot in the door without losing an arm and a leg.

I’ll be taking classes that will transfer to a Bachelors in Physics at the University of Texas at Austin.  From there, I’m hoping to push myself further into the field of astrophysics.

While I’ve got a long road still ahead of me, its nice to know I’m finally on the correct road.

Help Joshua Break Atmo

I am unable to put words to the incredible amount of conviction I have for the idea of interstellar travel/colonization. I believe that we, as an intelligent species, have not only the potential, but the NEED to push ourselves toward the future; and that future is the exploration and colonization of other worlds. To accept the mundane lives that we are generally presented with is absolute lunacy. We are meant for more than our menial existence currently entails; waking up, going to work, driving the economy, worrying about bills, etc.

If this world could somehow pull itself together, realize that money, violence, and religion get us absolutely nowhere but down, we would be able to pull our resources, our technology, and our passionate drive to make something incredible happen. We weren’t meant to stay here forever; and I believe that with every fiber of my being.

To have the once in a lifetime opportunity to see the curvature of the Earth with my own eyes, is something that I don’t want to let slip away.  Help support me in this endeavour to be the first person in my family to travel to space!

When you think of an astronomer, what do you picture? A house-sized observatory, filled with scientists, giddy as color images come rolling in? Or do you picture a handful of scientists, sorting through endless mounds of data that have been collected over a couple hours of observation without any of the breathtaking images you see in books? If you imagined the latter, you would have a much more realistic idea of what it means to be a professional astronomer.

Professionals in the field of astronomy simply cannot use their observatories at their whim. The operation costs of these professional installations are staggering. When taken into account the amount of money and energy required to run an observatory, one begins to realize why we are unable to spend more time searching the night sky for extrasolar planets. With billions and billions of stars in the Milky Way, it is nearly impossible for professional astronomers to continue collecting data on previously discovered exoplanets, let alone observe each star, looking for a new exoplanetary system.

The Gemini Observatory, located in both the Hawaiian Islands and the mountains of Chile, is comprised of two 26.9′ telescopes.  The government budget for the construction of this observatory was $193 million dollars, while consuming another $10 million dollars per year in operating costs.  Since this project was a venture between seven countries, the Gemini Observatory maintains an “open sky” policy, meaning any country is free to use the facility within reason.  Requests for reserved time are sorted through, and only the most relevant are accepted.  Once this happens, the allotted time per request may be as long as a few nights, or as little as an hour.  With numbers like that, the importance of the amateur community begins to come into perspective.

“When we discover the means for interstellar travel, which planet will we visit first?” Before this question can be answered, astronomers must conduct repeated observations of an exoplanet in order to decide whether or not it would be worth our efforts traveling to.

Amateur astronomers world-wide have begun taking great strides in the initiative of detecting  exoplanets, personally. How is this possible, without extensive observatories? While not as easy as pointing a telescope and seeing an exoplanet, technology continues to advance, and the techniques used continue to develop. Here’s a reference guide to get you started:

As an extrasolar planet orbits its parent star, the exoplanet will block out a small portion of the star’s light, similar to the way Venus passed between Earth and our Sun in June of 2012. This is referred to as a “transit.” As the exoplanet’s orbit takes it directly between its star and the Earth, the star’s apparent magnitude seems to dim for a period of time, then rebound to its original magnitude as the exoplanet moves to no longer obscure of our view of the star. The start, duration, and end of the “dip” are the focal points in creating a light-curve graph.300px-Planetary_transit.svg

(image source: http://en.wikipedia.org/wiki/Methods_of_detecting_extrasolar_planets)

In order to create a light-curve graph by use of the transit method, amateur astronomers need to capture a series of images containing the target star and reference stars, a process known as differential photometry. A reference star can be any additional bright object that is near the target star; this allows the astronomer to compare data collected from the target and reference stars to rule out atmospheric anomalies created by viewing from a ground-based telescope. Unfortunately, the process of capturing viable images is not as simple as pointing and shooting. A background in astrophotography will greatly increase an amateur astronomer’s success in their exoplanetary endeavours.

Next comes the analyzation and processing of the images. For a good number of people without any astronomical experience, the type of data collected can be overwhelming and confusing. Learning to comprehend and apply the data is a process that will take time and effort on the amateur’s part. Utilizing certain techniques such as polar alignment, defocusing, eliminating systematic error, subtracting dark frames, and preparing a flat field, will also have an enormous effect on results.

Bruce L. Gary (not to be confused with The Knack’s drummer, Bruce Gary), has written an amazing book on extrasolar planet observation dedicated to amateur astronomers.

Anyone, with patience and the eagerness to learn, can be taught to detect an extrasolar planet.

The first amateur observation of a planet orbiting around a star other than our sun, was by a team at the Nyrölä Observatory of Finland, a privately owned amateur observatory. On the 16th of September, 2000, a 16” Meade LX200 was aimed at HD 209458. This star is known for being the parent of the first exoplanet discovered, just a year before in 1999.  The telescope was equipped with an SBIG ST7E CCD camera, a photometric V-filter, a Meade f6.3 focal reducer, and JMI’s NGF-S digital focuser. After a night of observation and data processing, a light-curve graph showed the orbit of HD 209458b around it’s parent star. Without going into far too many depressing figures, the equipment used is generally far outside of the typical amateur’s price range.

Tonny Vanmunster made history by being the first amateur astronomer to detect the transits of exoplanets TrES-1b and TrES-2b, in the constellation Lyra. In Landen, Belgium, Mr. Vanmunster aimed his Celestron C-14 with SBIG ST-7XME CCD imager at a star creatively named GSC 02652-01324, and captured light differentials caused by both exoplanets.  Mr. Vanmunster has also contributed to the discovery of five more exoplanets.  Without factoring in the telescope mount that Mr. Vanmunster used, his equipment cost at least $6,000; still a bit steep for some amateurs.

Less than a year later, Ron Bissinger of California became the third amateur astronomer to detect an exoplanet. With his 14” Celestron SCT and SBIG ST-10XME CCD, Mr. Bissinger observed a partial transit of HD 149026b. According to the information that was given, Mr. Bissinger seems to have around a $10,000 setup.

Due to technology becoming more and more affordable, amateur astronomy is becoming an increasingly large field of interest. Transitsearch.org has a link to a database of extrasolar planets for amateur astronomers to detect.

Transit Search:http://www.transitsearch.org/

The amateur astronomers, who are listed above, would be considered very serious amateur astronomers. While having large telescopes and high definition imagers will definitely aid in your exoplanetary search, they are not required. Amateurs continue to push the limits on what can be done with more affordable equipment.

AstronomyOnline is an website owned and operated by a legally blind astronomer and photographer, Ricky Murphy, who has dedicated his online work to furthering the education of aspiring astronomers. On his page, he displays a light-curve graph of HD 209458b’s transit in front of its parent star. When compared to a professional graph of the same transit, the two are nearly identical. The amateur detection was made with an 8” telescope and a 765×510 pixel CCD camera! This is amazing: for approximately $4,000, any amateur could have the same equipment setup, and duplicate the results themselves.

Think that’s impressive? Michael Theusner, a “meteorologist, amateur astronomer and IDL software developer from Hannover, Germany,” as stated on his website, decided to experiment with small aperture telescopes, to test the possibility of capturing an exoplanetary transit with “modest” equipment.  Sure enough, Mr. Theusner observed a transiting planet around HD 189733 A, with a 2.4” telescope! The possibilities that are created by such an experiment are positively exciting.

There are quite a few well-known telescope companies, each marketing hundreds of telescopes, mounts, and imagers, all touting to be the best. Anyone will tell you that their telescopes will outperform the competition’s telescopes. When it comes to brand names, it is entirely personal preference.

As a baseline, any setup for exoplanet observation should include a computerized mount, as hands-free tracking is absolutely essential. While reports have surfaced of exoplanet detection using apertures as small as 2.4”, the average size of apertures used by amateurs seems to be roughly 12”.

Here is a basic setup with a smaller than average telescope for unbelievable prices to give the amateur astronomer an idea of a bare minimum to look for:

$1,500 – Celestron Advanced C8-SGT 8″/203mm Catadioptric Telescope (this includes an equatorial mount for polar alignment)

$400 – Orion StarShoot G3 Deep Space Color Imaging Camera (built around a 752 x 582 pixel CCD chip)

$400 – Any laptop that satisfies your technical desires from your friendly, neighborhood computer store.

In short, for less than $2,500, an amateur astronomer could create their own observations and light-curve graphs. Please bear in mind, this telescope, mount, and camera are based entirely on the author’s opinion; everyone has their own set of personal preferences.

The Paul and Jane Meyer Observatory, located between the towns of Clifton and Turnersville, TX, is privately owned by the Central Texas Astronomical Society.

Mr. Bradley Walter, the AAVSO Representative for CTAS, said in a recent email “We observe known exoplanets and record light curves to refine data. We are working toward doing confirming observations to assist with the confirmation of candidates. In general, we limit our targets to transiting planets having transit depths of 10 millimags or slightly less. However, one of our members has captured a Kepler candidate transit light curve with much less depth than that.”  A “millimag” is a very precise level of measurement in astronomical photometry, when calculating the apparent or absolute magnitude of a celestial object.  Due to the exoplanets being so much smaller than their parent star, only a very small portion of the star’s apparent magnitude dims, which calls for unbelievably scaled down measurements.

The Meyer Observatory houses a 24” aperture telescope with a Roper VersArray 1300B camera.

Moreover, Mr. Walter also stated: “Doing photometry of exoplanet transits does not require the level of equipment that we have at the observatory. People are doing it successfully with 10 and 12 inch telescopes and fairly low level astronomical CCD cameras like my old parallel port SBIG ST7. You need good skies, good technique in doing photometry and patience.”

To find a source of previously discovered extrasolar planets that you can detect, the ETD will be your best friend.  The Czech Astronomical Society is father to the Variable Star and Exoplanet Section, which hosts the Exoplanet Transit Database, or ETD. This database houses collections of observations from over one hundred transiting exoplanets. The data and light curves have been submitted not only by professional astronomers, but amateurs as well, and is home to a wonderful tool to “model-fit your data.” Amateur astronomers also have the option to view future transit predictions to aid in their personal observations.

To find a local astronomy group near you in the state of Texas, Go-Astronomy is a website with a very impressive list of contact information.

If you wish to contact a group that focuses on exoplanet observation, the European exoplanet site is dedicated to astronomy programs worldwide.

The numbers of the amateur astronomical community are growing quickly. Being a contributing member to an astronomy club, or even to Icarus Interstellar, does not require ownership of expensive equipment.

Dr. Richard Obousy, president of Icarus Interstellar, said, “Contribution to the endeavour might come in the form of helping with fundraising efforts, general admin of what could be an expanding project and member base, analyzing data, coordinating volunteers etc.”

Advances in technology are happening at a very rapid pace; where will you want to be when humanity achieves interstellar flight?

In the works…

November 27, 2012

As of today, I have more information and data collected for this guide than I know what to do with.  Good god this is a project.  I’ve been fighting with myself, trying to figure out whether or not I want to make this guide into a very in-depth, scientific explanation, or create a simplified, easier to read version with external hyperlinks to further explanations of certain topics.

After a couple of days of deliberation, I contacted Dr. Obousy with my dilemma.  The decision has been made: Wiki-style it is.

I would rather capture the imagination and interest of the reader throughout the entire guide, rather than see someone skipping over vital information due to the fact that it sounds overwhelming.  The whole idea behind this is to not only capture, but hold the interest of amateur astronomers everywhere.  There is a HUGE role we can play in the pursuit of interstellar travel. 

We’ve got to find the best exoplanetary candidate to start with…

Its been awhile…

November 22, 2012

Work has been demanding over the last few months.  Sadly enough, I haven’t had the time to devote to this blog as much as I would have liked.  However, that will be changing soon.

I have been in correspondence with Dr. Richard Obousy, president and senior scientist of Icarus Interstellar, for the last month or so.  I had initially taken it upon myself to email the Icarus team, in hopes of volunteering myself in some way, shape, or form.  Never did I imagine that I would be given such an opportunity:

I will be conducting research into exoplanetary discovery and analysis on behalf of Icarus Interstellar.  This research will be primarily focused on two things:  the amateur astronomer and the transit method.  The “transit method” is Layman’s terms for viewing the dip in a star’s light as a planet orbits between us and it’s parent star.  I will be calling amateur astronomy groups all over South Texas over the next month, filling my mind with knowledge and good conversation.

 

Here’s to the future!  This picture was taken on November 20, 2012, with a 4″ reflector and a camera phone held up to the lens.  Who says you need expensive equipment to take pictures of the night sky?Image

I find it incredible that people are taking the initiative to start up programs that will be able to take people into space…
Now, I can’t say people from the general population, because odds are that the tickets will be far too expensive for the average Joe.

…but my god, I want to see orbit so terribly badly that I plan to work towards that dream someday.

Mark my words: I will break atmosphere before I pass away.

I was a Corpsman in the United States Navy before I was discharged over claustrophobia. I had such aspirations for my military career: I wanted to be in the shit with the Marines, another boot in the sand, ground and pound. But that didn’t happen.

My best friend since early high school is also a Corpsman. He just made Third Class this morning, making him HM3.

I can’t even begin to describe how happy I am for him, but at the same time, I feel so upset that I’m not right alongside of him still, serving, moving forward, and fulfilling my dream.

My appreciation and respect goes out to all those who honorably serve our armed forces. I understand the sacrifices it takes. Thank you.

How did trends of today become the trends of today?

Who was the first person to infer that “cooking” the outer layer of your skin to create a darker, “tan” look, was awesome?  Why is it that pale skin isn’t attractive? Why is it that we perceive things as being attractive without ever forming said opinion ourselves?

Do we assume that tight jeans and tan skin are attractive because we are chemically balanced to think so, or is it because society tells us that its attractive?

If there was no such thing as “sexy,” attractive, or good looking as defined by society, would we as a people really care to begin with?

What makes our brains tell us that certain things are attractive? If humans truly did evolve from a lesser species, is it simply evolution? Or is it nothing more than an inferred perception of the populous?

So the Cyber Intelligence Sharing and Protection Act was passed today, regardless of the veto from the White House.

Now the government has access to absolutely any personal information you have on your computer. Thrilling, hmm?

I’ve half a mind of taking a picture of my nude hindquarters holding a sign displaying some witty anti-government remark… place said picture all over my computer… then start searching for bomb making material.
