A legally blind photographer/astronomer on disability so I use this site to contribute to society.
Last Updated: 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 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.
Visit this page: https://www.advancedwriters.com/custom-research-paper/ and get Astronomy research project writing assistance for University classes.

APOD:Car Orbiting Earth
Explanation: Last week, a car orbited the Earth. The car, created by humans and robots on the Earth, was launched by the SpaceX Company to demonstrate the ability of its Falcon Heavy Rocket to place spacecraft out in the Solar System. Purposely fashioned to be whimsical, the iconic car was thought a better demonstration object than concrete blocks. A mannequin clad in a spacesuit -- dubbed the Starman -- sits in the driver's seat. The featured image is a frame from a video taken by one of three cameras mounted on the car. These cameras, connected to the car's battery, are now out of power. The car, attached to a second stage booster, soon left Earth orbit and will orbit the Sun between Earth and the asteroid belt indefinitely -- perhaps until billions of years from now when our Sun expands into a Red Giant. If ever recovered, what's left of the car may become a unique window into technologies developed on Earth in the 20th and early 21st centuries.
APOD:In the Heart of the Heart Nebula
Credit & Copyright: Alan Erickson
Explanation: What's that inside the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. It's shape perhaps fitting of the Valentine's Day, this heart glows brightly in red light emitted by its most prominent element: hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the heart of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of the mythological Queen of Aethiopia (Cassiopeia).

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 (See Solar System App) 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.
