Astronomy is the scientific study of matter in outer space with the goal of determining or measuring factors such as distances, positions, dimensions, distribution, magnitudes, motion, composition, physical condition, energy, evolution, and the causes of their various phenomena. At present astronomy while making some important discoveries is still in its infancy in terms of gaining depth of understanding and some would argue has many errant notions.

Important branches in this discipline include astrophysics and cosmology. Astrophysics is a branch of astronomy that deals with the physics of stellar phenomena. Cosmology is the study of the origin, current state, and future of the cosmos. Astrophysical measurements and analysis are used to understand the cosmological history, structure, and constituent dynamics of our universe.

The sun (either from the Greek, helios or from the Latin word sol) is a G2 V star. All planetary objects and other systems within our solar system revolve around it.[7]...

In contrast, virtually every other civilization has regarded the Sun as one of many gods. The Egyptians called the Sun Ra or Re, a deity whom, they said, created the world.[10] The Egyptians also called the sun-disk Aten, and for a brief period (during the reign of Pharaoh Amenhotep IV or Akhenaten), actually worshipped Aten as the one and only god of the universe.[11] In Babylonia and Assyria the sun was called Shamash, a god who, because he could see everything happening on earth, was also associated with truth and justice.[12] The Greeks at first regarded Helios as a son of heaven and earth but later came to associate the Sun with their god of truth, Apollo.

The most common theme in all the sun-worship cults is the association of the sun with truth and justice personified. The second most common theme is the regarding of the sun as the creator.

Barred Spiral Galaxy NGC 1300

Explanation: Big, beautiful, barred spiral galaxy NGC 1300 lies some 70 million light-years away on the banks of the constellation Eridanus. NGC 1300 spans over 100,000 light-years and the Hubble image reveals striking details of the galaxy's dominant central bar and majestic spiral arms. In fact, on close inspection the nucleus of this classic barred spiral itself shows a remarkable region of spiral structure about 3,000 light-years across. Unlike other spiral galaxies, including our own Milky Way, NGC 1300 is not presently known to have a massive central black hole.

The National Aeronautics and Space Administration began on October 1, 19581 October 1958 17 Tishrei 5719 H 18 Eitanim 6117 AM, by an act of the United States Congress to establish an American presence in outer space. Today it is the foremost among government agencies that manage space programs, and is credited with some of the most exciting and surprising astronomical discoveries ever made.

“We cannot even show convincingly how galaxies, stars, planets, and life arose in the present universe.” Michael Rowan-Robinson, “Review of the Accidental Universe,” New Scientist, Vol. 97, 20 January 1983, p. 186.[1]

“The problem of explaining the existence of galaxies has proved to be one of the thorniest in cosmology. By all rights, they just shouldn’t be there, yet there they sit. It’s hard to convey the depth of frustration that this simple fact induces among scientists.” James Trefil, The Dark Side of the Universe. A Scientist Explores the Mysteries of the Cosmos, New York Charles Scibner's Sons: 1988, page 55.

“We don’t understand how a single star forms, yet we want to understand how 10 billion stars form.” Carlos Frenk, as quoted by Robert Irion, “Surveys Scour the Cosmic Deep,” Science, Vol. 303, 19 March 2004, p. 1750.

• Earth, Mars, Moon Have Different Origin, Study Says. In a direct challenge to the nebula hypothesis, French geologist Guillaume Caro says that the chemistries of these three bodies are inconsistent with, and unexplainable by, that model. National Geographic. March 19, 2008.
• Hubble Detects Organic Molecule on an Extrasolar Planet. The molecule involved is methane (CH₄), and the planet involved is too close to its primary to be hospitable for life. NASA press release. March 14, 2008.
• Creation Cosmologies Solve Spacecraft Mystery. D. Russell Humphreys, PhD, shows that the apparent "slowdown" of the spacecraft Pioneer 10 and 11 is actually evidence of an acceleration of the speed of light in extrasolar space. This in turn is evidence in favor of a straightforward Biblical interpretation of the description of the "firmament of heaven" on Creation Days 2 and 3. Impact articles, Institute for Creation Research, October 1, 2007.
• The Big Bang and the Bucks Set to Collide in Inner Space Scientists in Beijing unveiled a design for a machine 20 miles long that will slam together electrons and positrons, "to produce fireballs of energy recreating conditions when the universe was only a trillionth of a second old." Reportedly, the project will cost $6.7 billion and 13,000 "person-years" of labor to construct. NY Times. February 9, 2007.
• Big Bang Afterglow Fails An Intergalactic Shadow Test The apparent absence of shadows where shadows were expected to be is raising new questions about the faint glow of microwave radiation once hailed as proof that the universe was created by a "Big Bang." Moondaily. September 3, 2006.
