Welcome to
Astronomy Online
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.
This site stands as proof that, despite being legally blind, I can still contribute in meaningful ways. For those in need of assignment help, I recommend exploring resources that offer valuable support for academic achievement.

APOD: Athena to the Moon
Image Credit: Intuitive Machines
Explanation: Planet Earth hangs in the background of this space age selfie. The snapshot was captured by the IM-2 Nova-C lander Athena, just after stage separation following its February 26 launch to the Moon. A tall robotic lander, Athena is scheduled to touch down on Thursday, March 6, in Mons Mouton, a plateau near the Moon's South Pole. The intended landing site is in the central portion of one of the Artemis 3 potential landing regions. Athena carries rovers and experiments as part of NASA's Commercial Lunar Payload Services program, including a drill intended to explore beneath the lunar surface in a search for evidence of frozen water. It also carries a propulsive drone dubbed the Micro Nova Hopper. After release to the lunar surface, the autonomous drone is intended to hop into a nearby crater and send science data back to the lander.

APOD: Einstein Ring Surrounds Nearby Galaxy Center
Image Credit & Copyright: ESA, NASA, Euclid Consortium; Processing: J.-C. Cuillandre, G. Anselmi, T. Li
Explanation: Do you see the ring? If you look very closely at the center of the featured galaxy NGC 6505, a ring becomes evident. It is the gravity of NGC 6505, the nearby (z = 0.042) elliptical galaxy that you can easily see, that is magnifying and distorting the image of a distant galaxy into a complete circle. To create a complete Einstein ring there must be perfect alignment of the nearby galaxy's center and part of the background galaxy. Analysis of this ring and the multiple images of the background galaxy help to determine the mass and fraction of dark matter in NGC 6505's center, as well as uncover previously unseen details in the distorted galaxy. The featured image was captured by ESA's Earth-orbiting Euclid telescope in 2023 and released earlier this month.

APOD: Light Pillar over Erupting Etna
Image Credit & Copyright: Davide Calị
Explanation: Can a lava flow extend into the sky? No, but light from the lava flow can. One effect is something quite unusual -- a volcanic light pillar. More typically, light pillars are caused by sunlight and so appear as a bright column that extends upward above a rising or setting Sun. Alternatively, other light pillars -- some quite colorful -- have been recorded above street and house lights. This light pillar, though, was illuminated by the red light emitted by the glowing magma of an erupting volcano. The volcano is Italy's Mount Etna, and the featured image was captured with a single shot during an early morning in mid-February. Freezing temperatures above the volcano's lava flow created ice-crystals either in the air above the volcano or in condensed water vapor expelled by Mount Etna. These ice crystals -- mostly flat toward the ground but fluttering -- then reflected away light from the volcano's caldera.

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.
