A legally blind photographer/astronomer on disability so I use this site to contribute to society.
Last Updated: October 24, 2012 added graphics for the 88 constellations under Observation/The Night Sky.
This site is a testament that even though I have a physical disability - legally blind - I can still do things that helps other people. I even have a new project: Astro-Drummer, a site dedicated to my other hobby.
I also have a new image gallery. I call it Second Site Image Gallery.
This is an educational website. It's never too late to learn astronomy, even for those who have not completed their primary (High School) education. A GED can get you in the door to college level courses.

NASA Introduces New, Wider Set of Eyes on the Universe: Baltimore's Space Telescope Science Institute to Partner on New NASA 'Wide-View' Space Telescope
After years of preparatory studies, NASA is formally starting an astrophysics mission designed to help unlock the secrets of the universe the Wide-Field Infrared Survey Telescope (WFIRST). WFIRST will image large regions of the sky in near-infrared light to answer fundamental questions about dark energy and the structure and evolution of the universe. It will also find and characterize planets beyond our solar system, and as a general-purpose observatory, revolutionize many other astrophysical topics. WFIRST will have a mirror the same size as Hubble's, but it will have a 100 times wider view of space. Slated for launch in the mid-2020s, it will complement the capabilities of NASA's other major astrophysical observatories.
APOD:50,000 Kilometers over the Sun
Image Credit & Copyright: Pete Lawrence
Explanation: What's happening at the edge of the Sun? Although it may look like a monster is rampaging, what is pictured is actually only a monster prominence -- a sheath of thin gas held above the surface by the Sun's magnetic field. The solar event was captured just this past weekend with a small telescope, with the resulting image then inverted and false-colored. As indicated with illustrative lines, the prominence rises over 50,000 kilometers above the Sun's surface, making even our 12,700-diameter Earth seem small by comparison. Below the monster prominence is active region 12585, while light colored filaments can be seen hovering over a flowing solar carpet of fibrils. Filaments are actually prominences seen against the disk of the Sun, while similarly, fibrils are actually spicules seen against the disk. Energetic events like this are becoming less common as the Sun evolves toward a minimum in its 11-year activity cycle.
APOD:The Helix Nebula in Infrared
Image Credit: NASA, JPL-Caltech, Spitzer Space Telescope; Processing: Judy Schmidt
Explanation: What makes this cosmic eye look so red? Dust. The featured image from the robotic Spitzer Space Telescope shows infrared light from the well-studied Helix Nebula (NGC 7293) a mere 700 light-years away in the constellation of the Water Carrier Aquarius. The two light-year diameter shroud of dust and gas around a central white dwarf has long been considered an excellent example of a planetary nebula, representing the final stages in the evolution of a Sun-like star. But the Spitzer data show the nebula's central star itself is immersed in a surprisingly bright infrared glow. Models suggest the glow is produced by a dust debris disk. Even though the nebular material was ejected from the star many thousands of years ago, the close-in dust could have been generated by collisions in a reservoir of objects analogous to our own solar system's Kuiper Belt or cometary Oort cloud. Had the comet-like bodies formed in the distant planetary system, they would have survived even the dramatic late stages of the star's evolution.

Observation - This section includes information on
coordinate systems, constellations, objects visible in the
night sky, and some images of the night sky of the
northern and southern hemispheres.
Science - This section includes information on some
of the basic science used in astronomy. There is information
on the variety of tools used (like telescopes) as well as
methods of using them. There is a mathematics primer,
introduction to some physical processes, formulas used in
astronomy, and information on computer use in Astronomy.
- As indicated, this section covers our Solar System and
everything in it. It covers the Sun, planets, their moons,
asteroids, comets and exotic objects like TNO's and Kuiper
Stars - This section covers stars in our own galaxy.
It covers the variety of stellar evolution paths. It also
covers supernova, black holes, and some of the radiative
processes in the interstellar medium.
- This section covers our galaxy as well as some of the
nearby galaxies in our own Local Group. It also covers
- This section covers other galaxies and galaxies clusters.
It also covers the big bang, relativity and dark matter.
- This section covers the relatively new field in astronomy
- the possibility of life in our Solar System and the
Universe. There is also information on some of the projects
dealing with this - like SETI.
- This section covers the study of planets known to exist
around other stars. It covers both amateur and professional
involvement and shows you how you can get involved with the
search as well.
This section covers the fastest growing hobby of
astrophotography. This section offers information and tips
on photography and also features and Image Gallery.
