Many scientifically interesting variable stars are seldom observed at all. Since , the AAVSO has done a remarkable job of coordinating volunteer observations of variable stars. Millions of data points have been collected, and it is the AAVSO, not the large observatory, that supplies most data about variable stars to scientific researchers.

For centuries they attempted to discover the secrets of the Stars and the Universal Clock. They then realized that it took millions of years just to represent one revolution in the giant Universal Clock. Then at the end of such a great period, the Stars would find their original places again. At Mt. Wilson (using a inch telescope), Harlow Shapley becomes interested in variable stars, and is able to use the period of their oscillations to determine their distance. His work led us to believe that our solar system is located on the outside of the Milky Way.

PETER DOCKRILL. 6 AUG If summer and spring make you think of vivid, intense colours while winter recalls more subdued tones, there’s a perfectly good reason for that.

By 'star' i mean a bright object in the sky, might be a planet for all i know. in a short period of time, and the. Pulsating variable stars vary in radius and luminosity over time, expanding and contracting with periods ranging from minutes to years, depending on the size of the star.

This category includes Cepheid and Cepheid-like stars, and long-period variables such as Mira. I loved The Interrogative Mood by Padgett Powell.

Period. Why such declarative fervor. Because this is a book that pulled and moved me through the gamut of human experience without a single ending punctuation aside from a question mark. (What?) It’s a gimmick, but it was so much fun for me to participate in the play of it.

Dec 14,  · Photometry work with a C - posted in Observational Astrophysics: Hello from Greece,i am trying to find my way into photometry work (mainly binary systems and maybe exoplanet transits) and i am thinking of buying a Celestron C for that purpose.I already own an NEQ6 mount (hypertuned) and i have previous experience in CCD imaging (deepsky stuff).Would you suggest.

Oct 30,  · In a previous paper (Faulkner ) I evaluated 25 arguments for recent origin for the solar system. Here I evaluate 23 arguments for recent origin for the sun, stars, and galaxies.

Thus, between the two papers I discuss 48 arguments for young Author: Dr. Danny R. Faulkner. Is there something like color adaptation. I was wearing a blue light filter over one eye and felt that the differnce in color perception between the right and left eye disappeared after some time.

When removing the filter, color perception in the previously uncovered eye felt like wearing a blue light filter for a. Other alterations from novel to film are indefensible. As certain websites detail these I won't do it here, other than to warn you murder victims are changed willy-nilly; a romance ending one way ends another (in the book it's more shocking while the writers of this episode chose to make the romance more conventional and, in the end, unbelievable).

It is called a long-period variable star, because its variations of light take place in a period of months instead of a few hours or days, as is the case with stars such as Algol. Mira is not only a wonderful star, it is a mysterious star as well, for the cause of its light-changes are not known, as in the case of Algol where the loss of light.

An excellent student experiment about color and heat absorption. The following is documentation of a student's experiment with color and heat absorption.

Joseph-Louis Proust ( – ), over a period of eight years, showed that the variable compositions, even with very accurate analytical data, were due to the formation of different mixtures of two oxides of copper, CuO and Cu 2 O.

Each oxide obeyed the law of constant composition, but reactions that were supposed to lead to "copper oxide.Violet light is at the short-wavelength end of the visible spectrum ( nm), and red light is at the long-wavelength end of the visible spectrum ( nm), with the rainbow of colors in between.

In astronomy, stellar classification is a classification of stars based on their spectral characteristics. The spectral class of a star is a designated class of a star describing the ionization of its chromosphere, what atomic excitations are most prominent in the light, giving an objective measure of the temperature in this chromosphere.
