Welcome to
Astronomy Online
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 and a good place to start is a website like Kokopeli High School Academy - free evaluation and a 75% success rate.

InboxAstronomy: Hubble Sees Spiral Bridge of Young Stars Between Two Ancient Galaxies
It seems like our compulsive universe can be downright capricious when it comes to making oddball-looking things in the cosmos. The latest surprise to Hubble astronomers is a 100,000-light-year-long structure that looks like a string of pearls twisted into a corkscrew shape. This Slinky-like structure forms a bridge between two giant elliptical galaxies that are colliding. The "pearls" on the Slinky are superclusters of blazing, blue-white, newly born stars. The whole assembly, which looks like a tug-of-war, must result from the gravitational tidal forces present in the collision.

How the Website
is Organized:
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.
Solar System
- 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
Belt Objects.
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.
Our Galaxy
- This section covers our galaxy as well as some of the
nearby galaxies in our own Local Group. It also covers
galaxy evolution.
Cosmology
- This section covers other galaxies and galaxies clusters.
It also covers the big bang, relativity and dark matter.
Astrobiology
- 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.
Exoplanets
- 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.
Astrophotography -
This section covers the fastest growing hobby of
astrophotography. This section offers information and tips
on photography and also features and Image Gallery.
