2020-01-01 · Astronomy – Astronomy – The techniques of astronomy: Astronomical observations involve a sequence of stages, each of which may impose constraints on the type of information attainable. Radiant energy is collected with telescopes and brought to a focus on a detector, which is calibrated so that its sensitivity and spectral response.
The weather was just wonderful and on Friday and Saturday night we could observe through the night. I had a lot of first time viewings of some fantastic objects like the Flame Nebula and the complete Rosette Nebula. I also had the chance to observe a few Messier objects near.
The geometry of Egypt was mostly experimentally derived rules used by the engineers of those civilizations. They developed these rules to estimate and divide land areas, and estimate volumes of objects. Some of this was to estimate taxes for landowners. They also used these rules for construction of buildings, most notably the pyramids.
Lyra is a northern summer constellation, which is highest in the midnight sky in the months around June. It is best known for its brightest star, Vega, which forms one vertex of the Summer Triangle asterism.
2019-12-31 · Roman Egypt produced the greatest astronomer of the era, Ptolemy (90-168 CE). His works on astronomy, including the Almagest, became the most influential books in the history of Western astronomy. Following the Muslim conquest of Egypt, the region came to be dominated by Arabic culture and Islamic astronomy.
Of all the inventions used in astronomy, the telescope is the most important instrument for astronomers. Whether they use it atop a mountain in a huge observatory, or in orbit, or from a backyard observing spot, skygazers are benefitting from a great idea. So, who invented this incredible cosmic time machine?
Here is a quick picture of the Eskimo Nebula, also known as Caldwell 39 and NGC 2392. This picture was taken by my younger son with direction from me. We were just messing around and he wanted to take a picture. Since he likes lots of color, I thought this nebula might be a neat one to take.
2019-12-30 · Developed as a shaft coating to be deposited by thermal spraying to protect foil air bearings used in oil-free turbomachinery, like gas turbines, this advanced coating, PS300, was meant to be part of a larger project: an oil-free aircraft engine capable of operating at high temperatures with increased reliability, lowered weight, reduced.
Metals in astronomy. In astronomy, a metal is any element other than hydrogen or helium. This is because these two elements (and sometimes lithium) are the only ones that form outside stars. In the sky, a spectrometer can see the signs of metals and show the astronomer the metals in.
There are individual charts for the Messier Catalogue, Caldwell Catalogue and the Herschel 400 Catalogue, see the Star Charts page for more information. These catalogues can be downloaded as spreadsheets and PDF documents. There are also individual finder charts for objects (e.g: Messier 45) and constellations (e.g: Orion).

CFAS Observing Certificate Program. After many years CFAS will now have an official Observing Certificate program for its members. The Observing chairman has agreed to develop Observing Certificates for the following : Moon, Messier, Caldwell and Herchel 400.
Newton’s universal law of gravitation works for the planets, but is it really universal? The gravitational theory should also predict the observed acceleration of the Moon toward Earth as it orbits Earth, as well as of any object (say, an apple) dropped near Earth’s surface.

The Caldwell objects are a catalog of bright and exceptional non – stellar DSOs (Deep Sky Objects) that do not appear on the famous Messier Catalog. Is this a catalog developed by the late Sir Patrick Alfred Caldwell – Moore who is known throughout the international Amateur Astronomy community for his career and promotion of Astronomy to the general public in all forms of media.
Not everyone likes the term Caldwell catalogue. It was a catalogue devised in 1995 by the British amateur astronomer, prolific author, and TV personality Sir Patrick Moore in an attempt to list all of the "easy" deep sky objects not catalogued by Charles Messier in his 18th century catalogue.
I recommend you buy The Caldwell Objects and how to observe them.” (Gordon Rogers, Journal of the British Astronomical Association, Vol. 120 (1), 2010) “If you’re tired of the same old Messier objects and want to see something that doesn’t have an ‘M’ number, The Caldwell Objects And How To Observe them is definitely for you.
