I'm a retired middle school math teacher and cross country coach. Before teaching, I worked as a software engineer. I am interested in computers, math, science, history, and politics. I enjoy running, amateur astronomy, drone photography, and programming.

Donald Trump as the Creature from the Black Lagoon, emerging from the reflecting pool in Washington DC.
A ring of reddish nebula set against a field of stars.
Irregular red nebula fills the center of the image, with a black horizontal ragged scar-like area below center of the nebula. The nebula is set against a dense field of stars.
Northern lights above a few houses and trees. A band of green is just above the horizon, with some waviness and vertical pillars. There is some fainter red above the green.
Bright red aurora rising diagonally above some trees and houses in the distance.
View of the northern night sky above a suburban development, showing a curtain of greenish northern lights with some brighter pillars. On the right side is a pinkish pillar.
A spiral galaxy fills the center quarter of the image, with several brighter spots in each arm of the galaxy. The galaxy is set against a field of stars.
A spiral galaxy fills the center of the image, a bright oval tilted from the upper left to the lower right. The center is a bright blob, surrounded by brownish rings circling the center of the galaxy. Many stars fill the background, with one bright bluish star at the center left of the image.
Hint of purple and green northern lights low in the sky above several trees in the distance, with a few houses also in the distance. A few stars are visible in the sky above the northern lights.
A oval nebula with the longer dimension vertical is in the center of the image. It is mostly blue-green with reddish colors on the left and right and a bit at the top and mixed in tangles through the nebula. The nebula is set against a dense field of thousands of stars, with one brighter star to the upper left.
Bright blue nebula in the center surrounded by darker brown nebula, all set against a field of stars.
A bright ball of thousands of stars make up this globular cluster in the center of the image. The cluster is set against a field of stars with one reddish star to the lower right of the cluster.
A galaxy appearing as a bright oval core, surrounded by a not quite as bright ring, with a much dimmer ring surrounding those. There is some spiral structure barely visible in the brighter ring and core.
A large spiral galaxy with two distinct spiral arms fills the center of the image. A nearby smaller galaxy is connected to one of the larger galaxy's spiral arms. A cloud of white gas surrounds the smaller galaxy.
A spiral galaxy fills the center third of the image. Several bright arms spiral away from a very bright core. The spiral arms are distorted by the gravity of other nearby galaxies. The galaxy is set against a field of dimmer stars.
Two galaxies set against a field of stars. On the upper right is Bode's Galaxy, a classic spiral galaxy with a bright core and several arms it a tight spiral away from the core. There is some lumpiness in those spiral arms. On the lower left is the Cigar Galaxy. It is seen on edge. It is less well-defined, a little fuzzy around the edges. There are some reddish filaments crossing the body of the galaxy.
The full moon during totality during the lunar eclipse on March 13-14, 2025. The moon is colored deep red with a bit of lightness at the top. There are a few stars visible in the background.
Reddish nebula fills the center of the image from the top to the bottom. In the center of the image is dark dust in the shape of the head of a horse (with the top of the head pointing to the right and the nose pointing up) covering part of the red nebula.
A bright nebula fills the center of the image, with bright white color at the top left and more reds to the lower right and dusty brown streaks running through it. There is a clump of white, red, and brown at the top left of the main nebula, and a smaller dimmer detached nebula above it that is more bluish in color.
The right center of the image is filled with a bright read nebula in the shape of a jellyfish, extending from the center of the image diagonally towards the lower right. There is a fainter nebula filling most of the upper left quarter of the image, reaching towards and just touching the Jellyfish Nebula's "head" .
A cluster of stars fills the center of the image, set against a more sparse background of stars. A circular bit of nebula is in the lower right corner.
A cluster of bright stars filtered through clouds of bluish white dust in the center of the image, set against a background field of dimmer stars.
The sun is in the center of the image with a halo of white surrounding it. The sun is low in the sky, with houses and trees visible.
A dense cluster of stars fills the center of the image, set against a field of stars in the background.
A red nebula extends across the image from the lower left to the upper right. The nebula is visibly tangled. The nebula is set against a field of stars, with one much bright star below the nebula just right of center.
A cluster of stars in the center of the image, with a few reddish stars and other bluish stars making up the cluster. There is some bluish nebula to the left of the cluster of stars, and some very faint bluish nebula mixed in with some of the stars. To the left of the cluster and nebula is a faint black thin cloud of dust, barely darker than the background. All of this is set against a background of stars.
The full moon visible above a profile view of a couple of homes. The moon is shining brightly through thin clouds, lit by the moon, with a ring around the moon.
Cluster of stars set against a background of many other stars. The cluster includes a pair of bright stars at the top with dozens of bluish stars below and a reddish star to the right.
A ghostly nebula in the center of the image, with a brighter V shaped part at the bottom center and a slightly fainter arc of nebula above it. Nearby is a very bright star. All of this is set against a background of many dimmer stars and a few brighter stars.
Two reddish nebulas against a background of thousands of stars. One nebula fills the top right quarter of the image is shaped like a drawing of a heart with filament of nebula extending to the upper center. The other nebula fills the bottom left quarter of the image and is shaped more like an elongated blob.
Photo of the Orion Nebula, bright red, brown, and white gases in a field of stars of varying brightness.
Green curtains of northern lights just above the horizon above homes with Christmas lights.
