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.
InboxAstronomy:Hubble Helps Find Smallest Known Galaxy with a Supermassive Black Hole
Astronomers have found an unlikely object in an improbable place: a monster black hole lurking inside one of the tiniest galaxies known. The dwarf galaxy containing the black hole is the densest galaxy ever seen, cramming 140 million stars within a diameter of about 300 light-years (just 1/500th of our Milky Way galaxy's diameter). However, the black hole inside the galaxy is five times the mass of the black hole at the center of our Milky Way. This suggests that the dwarf galaxy may actually be the stripped remnant of a larger galaxy that was torn apart during a close encounter with a more massive galaxy. The finding implies that there are many other compact galaxies in the universe that contain supermassive black holes.

How the Website
Advertising within text will be in italics with a link to the ad source.
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.
