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.

APOD:Carina Nebula Close Up
Image Credit: NASA, ESA, Hubble, ESO, Amateur Data; Processing & Copyright: Robert Gendler & Roberto Colombari
Explanation: A jewel of the southern sky, the Great Carina Nebula, also known as NGC 3372, spans over 300 light-years, one of our galaxy's largest star forming regions. Like the smaller, more northerly Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye, though at a distance of 7,500 light-years it is some 5 times farther away. This gorgeous telescopic close-up reveals remarkable details of the region's central glowing filaments of interstellar gas and obscuring cosmic dust clouds in a field of view nearly 20 light-years across. The Carina Nebula is home to young, extremely massive stars, including the still enigmatic and violently variable Eta Carinae, a star system with well over 100 times the mass of the Sun. In the processed composite of space and ground-based image data a dusty, two-lobed Homunculus Nebula appears to surround Eta Carinae itself just below and left of center. While Eta Carinae is likely on the verge of a supernova explosion, X-ray images indicate that the Great Carina Nebula has been a veritable supernova factory.
APOD:To Fly Free in Space
Image Credit: NASA, STS-41B
Explanation: What would it be like to fly free in space? At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was living the dream -- floating farther out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured, was floating free in space. McCandless and fellow NASA astronaut Robert Stewart were the first to experience such an "untethered space walk" during Space Shuttle mission 41-B in 1984. The MMU worked by shooting jets of nitrogen and was used to help deploy and retrieve satellites. With a mass over 140 kilograms, an MMU is heavy on Earth, but, like everything, is weightless when drifting in orbit. The MMU was later replaced with the SAFER backpack propulsion unit.
|The Hope Mars Mission or Emirates Mars Mission is a space exploration mission of sending a probe to Mars to explore and study the planet's atmosphere. Take a look at 15 interesting facts about the mission to learn more about it and better understand why it is so important.

around other stars. It covers both amateur and professional
involvement and shows you how you can get involved with the
search as well.
