Seeing the Light: the Art and Science of Astronomy
Chapter 1 Seeing the Light: The Art and Science of Astronomy In This Chapter ▶ Understanding the observational nature of astronomy ▶ Focusing on astronomy’s language of light ▶ Weighing in on gravity ▶ Recognizing the movements of objects in space tep outside on a clear night and look at the sky. If you’re a city dweller Sor live in a cramped suburb, you see dozens, maybe hundreds, of twin- kling stars. Depending on the time of the month, you may also see a full Moon and up to five of the eight planets that revolve around the Sun. A shooting star or “meteor” may appear overhead. What you actually see is the flash of light from a tiny piece of comet dust streaking through the upper atmosphere. Another pinpoint of light moves slowly and steadily across the sky. Is it a space satellite, such as the Hubble Space Telescope, or just a high-altitude airliner? If you have a pair of binoculars, you may be able to see the difference. Most air- liners have running lights, and their shapes may be perceptible. If you liveCOPYRIGHTED in the country — on the seashore MATERIAL away from resorts and develop- ments, on the plains, or in the mountains far from any floodlit ski slope — you can see thousands of stars. The Milky Way appears as a beautiful pearly swath across the heavens. What you’re seeing is the cumulative glow from millions of faint stars, individually indistinguishable with the naked eye. At a great observation place, such as Cerro Tololo in the Chilean Andes, you can see even more stars. -

Spectral Classification of Stars

Introduction Scientists across all fields use classification systems to help them sub-divide the vast universe of objects and phenomena into smaller groups, making them easier to study. In biology, life can be categorized by cellular properties. Animals are separated from plants, cats separated from dogs, oak trees separated from pine trees, etc. This framework allows biologists to better understand how processes are FIGURE 1: SPECTRUM OF VEGA interconnected and quickly predict characteristics of newly discovered species. In Astronomy, the stellar classification system allows scientists to understand the p r o p e r t i e s o f s t a r s . E a r l y astronomers began to realize that the extensive number of stars exhibited patterns related to the starʼs color and temperature. This classification was good, but had limitations (especially for studying distant stars). By the early 1900ʼs, a classification system based on the observed stellar spectra was developed and is still used today. A STELLAR SPECTRUM is a measurement of a 1 Spectral Classification of Stars starʼs brightness across of range of wavelengths (or frequencies). It is in a sense a “fingerprint” for the star, containing features that reveal the chemical composition, age, and temperature. This measurement is made by “breaking up” the light from the star into individual wavelengths, much like how a prism or a raindrop separates the sunlight into a rainbow. -

Architecture for Space-Based Exoplanet Spectroscopy in the Mid- Infrared
Architecture for space-based exoplanet spectroscopy in the mid- infrared Joseph Green*, Case Bradford, Thomas Gautier, Michael Rodgers, Erkin Sidick and Gautam Vasisht Jet Propulsion Laboratory, California Institute of Technology, 4800 Oak Grove Drive, Pasadena, CA 91109 ABSTRACT Characterizing exoearths at wavelength about 10 micron offers many benefits over visible coronagraphy. Apart from providing direct access to a number of significant bio-signatures, direct-imaging in the mid-infrared can provides 1000 times or more relaxation to contrast requirements while greatly shortening the time-scales over which the system must be stable. This in-turn enables tremendous relief to optical manufacturing, control and stability tolerances bringing them in- line with current technology state of the art. In this paper, we explore a reference design that co-optimizes a large segmented linearized aperture telescope with one-dimensional phase-induced aperture apodization providing high-contrast imaging for spectroscopic analysis. By rotating about a parent star, the chemical signatures of its planets are characterized while affording additional means for background suppression. Keywords: Exoplanet Spectroscopy, Segmented Space Telescopes, Strip Apertures, PIAA, Mid-Infrared, Coronagraphy 1. INTRODUCTION There have been many concepts over the years pursuing the objective direct imaging and characterization of exoearths in the visible wavelengths. The Terrestrial Planet Finder Coronagraph (TPFC) mission was an earlier examples that found in the baseline -
The COLOUR of CREATION Observing and Astrophotography Targets “At a Glance” Guide
The COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography. There is NO copy right - download at will. Warm regards.

A Case for Zeta Reticuli
A case for Zeta Reticuli One of the more famous “Alien” abduction stories, occurred in the early 1960’s. The Betty and Barney Hill event and case is now well documented, and obfuscated. But there was one single piece of data that came from that case that can be used; it is a “template”, or as it is identified, a “star map”. Betty was given the post-hypnotic suggestion that she could sketch a copy of the "star map". Although she said the map had many stars, she drew only those that stood out in her memory. Her map consisted of twelve prominent stars connected by lines and 13 lesser stars that form several distinctive groups. She said she was told the stars connected by solid lines formed "trade routes", and dashed lines were to less-traveled stars. 1: Original Hill map and our template. 2: Stars of Zeta Reticuli Interest Group There are a total of 25 stars in the template with 13 identified by Marjorie Fish around 1968. Much of her efforts were undone by others who knew little about Astronomy, in any case, Ms. Fish’s work has served well to start this analysis. Computer modeling and Datasets To create our view of the stars, and make a search for a match possible we created several database tables to use with Microsoft’s SQL server. DataSets Hipparcos The word "Hipparcos" is an acronym for High precision parallax collecting satellite. It was launched in 1989 by the European Space Agency and collected data on over 118,000 stars. -

Kataloglarda 300 kadar büyük kütleli OB yıldızı, etkileşen çift yıldız bileşeni durumundadır. OB bileşenli çift yıldız sistemlerinde ışık eğrisini bozan çevresel etkiler vardır. Bu çevresel etkiler ışık eğrisinde kendini minimumlarda asimetri ve minimum genişliklerinin eşit olmaması şeklinde gösterir. Bu tür sistemlerde (değen ve yarı-değen türlerde) aşırı kütle kaybı ve izotropik olmayan yıldız rüzgarı ile sistemi terkeden madde, sistem etrafında homojen olmayan birikim bölgeleri, sistemi saran bir zarf oluşturur. -
