A few months ago, I found some of these:

On my early morning walk a few days ago, I found another and decided to adopt it.

I was remembering again my favorite biology teacher and thinking to myself, “Self, what is this caterpillar going to become?” So I brought it home, placed it in a jar with a shoot of bamboo (for structure), a sprig of basil (for sustenance) and a wisteria seed pod (for transportation). I thought I would take some photos of the current specimen, but it turns out it was shy, and by the afternoon, it had wrapped itself in the leaves. So now I have this:

A wonderful structural detail:

From the archives, a mug shot (or a tail shot, it’s hard to tell):

I love these feet:

That’s all. Well, okay, one more of those wonderful feet:

So, after I found my caterpillar and decided to adopt, I had to carry it back home. I placed it on a leaf and went on my way, only to pass three or four people walking their dogs. Some people walk their dog, I walk my caterpillar. You know, ’cause that’s what you do when you have a caterpillar.

I am not going walk the cocoon…that would be weird.

Stay tuned…

A few weeks ago, this moth caught my eye in our garden. I grabbed my camera and stealthily took pictures of my newly-found subject. Well, I thought I was stealthy. After a few minutes, I wanted to see if I could coax the moth to change position (“Turn a bit more toward the light please and chin up.”) only to find that it was dead. Now it is part of my collection of curiosities and a permanent point of inspiration.

One of the things I love about macro photography is that I end up being able to see things in the captured image that I cannot see with my naked eyeballs. Case in point:

Luscious. If there are any lepidopterists reading this, I would be grateful to know the species of my furry find.

This 1869 photograph by John Thomson is from the collection of the Wellcome Library in London. A Manchu man and girl are taking in a traveling peep show. The photo was taken in Peking, Pechili Province, China (when it was still Peking).

The Wellcome collection is another treasure trove of images that I only have begun to explore…

Enjoy.

Nothing like looking at highly-detailed images of another planet to make me feel infinitesimally tiny…but in a very good way.

The web site for the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter currently has 6,137 high-resolution images of the Martian surface available for exploration. According to the Planetary Data System (did you know we had one of those?), HiRISE has released over 26 terabytes of data. The images below are from some of the observations taking place between 20 March and 24 April 2008.

To say that this is a small sampling is an understatement of planetary proportions. These snippets are from the June release of images and I only have looked at the first twenty-three of fifty pages.

Below, they were looking for “change due to mass wasting on scarps of different slopes”. I didn’t know what a scarp was before today, even though I have seen them (here on Earth).

Did you know that a barchan was a crescent-shaped dune? One of the things I love about the HiRISE pages is that many have very detailed descriptions. Click though on the image below for more information on the barchan and, I am guessing, its smaller relatives, the barchanoids.

Update/correction: Turns out that a barchnoid is not the smaller relative of a barchan, but rather is a transitional form between barchans and dunes…the nuances that come from specializations. “The transition is much more gradual…from barchans to barchanoids, to barchanoids with increasing slipface lengths, to dunes with barchanoid characteristics like crescentic slipfaces and tails, to dunes with irregular slipfaces, to more or less two-dimensional dunes.” [Source] Also, there is an article on the geology of sand dunes by John Mangimeli that has some nice illustrations.

Each of the images above is linked directly to its HiRISE page where you can find specific information about the observation and download various versions of the data. I gravitate to the RGB color, non-mapped versions, as shown here.

As a technical note, many of the images are stored in the JPEG2000 format and are very high resolution. During my time lost in the Library of Congress earlier in the week, I came across LizardTech’s ExpressView browser plug-in/viewing application. It handles both MrSID and JPEG2000 files. The plug-in and application come in the same download (as least for Mac OS X).

For a final bit of perspective, an observation from 3 October 2007:

That’s our home and our moon seen from the orbit of another planet.

Enjoy.

Back in the fifth grade, I had a wonderful biology teacher, Mrs. Bosert. I have very distinct memories of staying after class to look through the microscopes at squiggly little creatures zipping across the field of view.

A few years ago, I came across two sites with deep collections of Victorian-era prepared microscope slides. Individually, each slide has its own interesting elements — specimens, labels, nomenclature, &c. As a group, they are a fascinating and beautiful slice of the history of science and discovery.

While I have shown fifteen, between the two sites there are well over five hundred slides to peruse.

Enjoy.

P.S. I would love to see them as larger images also. The subject of “Victorian microscope slides”is now entered on the standing research list.
