Welcome to Astronomy Online
A legally blind photographer/astronomer on disability so I use this site to contribute to society.

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: Infant Galaxies Merging Near 'Cosmic Dawn' Astronomers using the combined power of NASA's Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered a far-flung trio of primitive galaxies nestled inside an enormous blob of primordial gas. The rare triple system existed when the universe was only 800 million years old. The trio may eventually merge into a single massive galaxy, researchers predict. The researchers state that the system provides key insights into the earliest stages of galaxy formation.

Last Updated: October 24, 2012 added graphics for the 88 constellations under Observation/The Night Sky.

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.
