I thought I would issue a plug for a talk I'm giving shortly. On this Thursday, July 28 at 8:00 PM I will be presenting a talk on epsilon Auriage and Citizen Science at Nebraska Nature and Visitor's Center during the Platte Valley Astronomical Observers's monthly meeting. Weather permitting, we'll also have an observing session afterward. So, if you happen to be somewhere nearby we'd be happy to have you attend.
About a month ago I wrote a post discussing what I'm doing with some astrometric data from the Sproul Observatory. This week I'm happy to report I have the paper almost entirely written and am working out the last few kinks in the analysis. It's been a serious uphill battle in both learning about astrometry and reducing the data, but I think it's been worth it.
In this post I'm going to talk a little more about the data and how it is reduced. In the prior post I mentioned that the data was taken on photographic plates starting in 1938 and ending in the early 1980s. I only have a small subset of the entire set from Sproul (about 40% actually) which is enough to show the effect I was looking for, but not much more.Read more
On behalf of my coauthors I am pleased to announce that Tom Pearson, Brian Kloppenborg, and Heinz-Bernd Eggenstein will have an article in tomorrow's release of The Classroom Astronomer, an education magazine for secondary and undergraduate education. There is a sampler for the next issue that includes a one-page excerpt from our articleRead more
It's not that often that I put up two blog posts in the same day, but I couldn't wait for this one. In the past I've had trouble answering the question of "what has astronomy done for me" or "how can pure research benefit the economy."
Well, today I have a clear example of how something from astronomy is helping a different field which, in turn, helps people:
In the article they describe how AO, used to stabilize astronomical images from being blurred by Earth's atmosphere, has now been used to image a living retina. This could, in turn, lead to earlier diagnosis of eye diseases earlier and save people's eyesight!Read more
Back in January 2011 Eric Jensen of Swarthmore College, home of the Sproul Observatory, provided me with three stacks of papers from the late Dr. Peter Van de Kamp. These pages contained raw and processed astrometric data on epsilon Aur which. As you might recall, my initial post on this topic explained that there is a strong disagreement between the orbits implied by the Van de Kamp orbital solution and the more recent interferometric data from CHARA.
Today I had the opportunity to talk with a group of high school students in an astronomy class at University Schools, a charter school, up the road in Greely, CO. The last time I was around high school students was when I did some classroom observing as part of the education program at my undergraduate institution, Hastings College. The group came to DU's historic Chamberlin observatory as part of an outing to Denver.
I spent the entire day Friday reading papers. I can already imagine your groans of disapproval for such an exciting blog post idea, but in reality reading papers is a critical portion of research. Sometimes the papers you read really help you with your research, and other times they smash your hopes of making a new contribution. It's this horrible aspect that happened today and I thought I would spend a few minutes discussing where one can go from here.
I have recently been contacted by the editor for a magazine entitled "The Classroom Astronomer" about writing an article discussing how DSLR cameras can be used in the classroom. The magazine is geared towards secondary and undergraduate teachers who have an interest in astronomy. The article is suppose to answer two primary questions:
- What you can do with a DSLR Camera
- Why you should use it in the classroom
