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

88 constellations under Observation/The Night Sky.

Cepheus

This site is a testament that even though I have a physical disability - legally blind - I can still do things that helps other people.


This site stands as proof that, despite being legally blind, I can still contribute in meaningful ways.


I also have a new image gallery. I call it Second Site Image Gallery.

APOD:M74: A Grand Design Spiral
Image Credit: NASA, ESA, and the Hubble Heritage (STScI / AURA)- ESA / Hubble Collaboration Acknowledgment: R. Chandar (U. Toledo) & J. Miller (U. Michigan)

Explanation: If not the most grand, then this spiral galaxy is at least one of the most photogenic. An island universe of about 100 billion stars, 32 million light-years away toward the constellation Pisces, M74 presents a gorgeous face-on view. Classified as an Sc galaxy, the grand design of M74's graceful spiral arms are traced by bright blue star clusters and dark cosmic dust lanes. Constructed from archival images, this sharp composite is from the Hubble Space Telescope. Spanning about 30,000 light-years across the face of M74, it includes exposures recording emission from hydrogen atoms, highlighting the reddish glow of the galaxy's large star-forming regions.

APOD:The Eclipse and the Stork

Image Credit & Copyright: Włodzimierz Bubak Text: Cecilia Chirenti (NASA GSFC, UMCP, CRESST II)

Explanation: How do animals react to a total solar eclipse? The featured image shows a stork roosting on her nest in Poland at a partial phase of the recent total solar eclipse. If you are lucky enough to experience a total eclipse somewhere quiet and close to nature, you may be able to notice unusual daytime animal behaviors. During totality, you may hear nighttime sounds like crickets and frogs and see fireflies. In the dark, most birds are quiet. Thinking that it is time to go to bed, ducks and other waterfowl prepare to sleep on one leg, with their heads turned around and their beaks tucked into their back feathers (they don't really sleep with their heads tucked under one wing). When sunlight returns at the end of totality, songbirds greet the new "morning" with their dawn songs. The crickets and frogs go quiet again. Animals and people resume their lives, only briefly disturbed by the chance alignment of our Sun and Moon.

Is It Fate In The Sky, Or Merely A Mirror Of What We So Desperately Want To Believe?


APOD:Nā ʻUhane Māhoe Huki Pū i ke Ola

Explanation: Nā ʻUhane Māhoe Huki Pū i ke Ola, is the Hawaiian name given to this image of a pair of spiral galaxies locked in a mutual gravitational embrace. Some 200 million light-years distant toward the high flying constellation Pegasus their spectacular, galactic scale merger is captured in sharp detail in the image from the 8.1 meter Gemini North telescope on Maunakea, Hawai'i. The galaxy pair, known as NGC 7253 and Arp 278, was chosen as a target, researched, and given a Hawaiian name by high school students in the joint Gemini Observatory and University of Hawaiʻi Project Hōkūlani internship program. The name translates to "The Twin Spirits Pulling Together Creating Life". That's both culturally and astronomically appropriate for galaxy collisions that trigger a cosmic maelstrom of star formation from galactic reservoirs of elemental building blocks of life. These merging galaxies are found within a region of Pegasus identified as the Hawaiian navigational constellation Ka Lupe o Kawelo.

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.
