British Astronomical Association Supporting amateur astronomers since Also: insights into Solar Cycle 24, an interview with the Astronomer Royal for Scotland and our first equipment review. Also: a lunar impact caught in the act, Hydra's deep sky delights and saving the night sky.
It provides predictions for grazing occultations of stars by the Moon and predictions for occultations of stars by asteroids and planets, information on observing equipment and techniques, and reports to the members of observations made. The organization wants to educate everyone about the value and effectiveness of quality nighttime lighting. One can also find a document collection of user guides, programmer guides, and on-line help files.
Amateur The following is a list of some of the major software products that are used by many amateurs, and by some professionals. At a minimum, these programs will include: variable date and time range at least plus or minus 2, years from the current date and the ability to view the sky from just about any location on earth. They can show the position of all of the planets, the Moon, comets, asteroids, thousands or millions of stars and thousands of deep-space objects such as galaxies, star clusters, and nebulas.
Extra features might include: an eclipse finder, ability to see the universe from other astronomical objects besides the earth, an ability to download or input data for tracking of new comets, telescope control, and more. When they include more features, more stars, and more deep-space objects, then it will probably cost more. They also distribute CCD Cameras and high-end telescope mounting systems.
Useful for the casual amateur astronomer to the serious amateur or professional. The features of version 8 may appeal more to advanced amateurs. Recently updated. Some things that astronomers study include: the Moon, the Sun, the planets, planets outside our solar system extrasolar planets , comets, stars and their formation, other galaxies, and the whole universe.
By Astronomical Object Most of these web sites will provide scientific data and images. Most of these web sites are from research facilities, and they will document what instruments the facility has, who does research there and the scientific results that have been obtained. The Institute is housed in the USRA Center for Advanced Space Studies CASS in Houston, Texas and includes a computing center, extensive collections of lunar and planetary data, an image-processing facility, a scientific visualization facility, an extensive library, publishing services, K online educational resources, and sponsorship and facilities for workshops and conferences.
Points to research by LPL faculty, outreach programs, conferences that they are hosting, a Space Imagery Center, and more. For example, there have been 19 missions just to the planet Mars, and another six missions are in the planning stages. Provides access to scientific data, and one can find very recent drawings of sunspot groups.
Will help astronomers figure out more of the interactions between the Sun and the Earth's environment. Learn about some of their discoveries of multiple-planet systems, transiting planet, and Saturn-mass planets. Read about how extrasolar planets can be different from our solar system. They provide background information concerning the "Doppler Detection Method," other detection methods, and their future goals. This web site provides a description of what those missions will attempt to do, and the tools that extrasolar planet hunters use to find those planets. Comets also reside in a vast cloud, now called the Oort Cloud, at the outer reaches of the solar system.
Links to many other SEDS web pages for terms and concepts. Points to reputable governmental and educational web sites for more images and data. Provides references for further reading. Keel at the University of Alabama. Nice short overview for anybody that wants to learn about galaxies and their properties.
Seems to be aimed at undergraduate science majors.

Has 36 "virtual lectures", and the first four are: an introduction, history, catalogues and data sources, and galaxy classification. Starts with a one paragraph introduction, then the text leads the reader to sections on the foundations, observational tests, limitations and extensions of the Big Bang theory. One can then tackle "Our Universe" to read about what matter is, and the age, shape, and ultimate fate of the universe. By the Wavelength of Observation For Hundreds of years, all astronomical observation was performed in the visual wavelengths of light.
But, visible light is just a very narrow band of the electromagnetic spectrum. In the last 50 years or so, with radio telescopes and space based observatories, astronomers have been able to observe astronomical phenomena outside of the visual wavelengths. Observed phenomena now occurs from the shortest to the longest wavelengths: cosmic rays, gamma rays, x-rays, ultraviolet, visible, infrared, microwave and radiowave. Most of the following observing programs will provide scientific data and results, images, and supplemental information for students and educators. Many of these web sites are at either governmental or educational institutions, so they almost always have a mission to provide educational outreach to the public and to educators.
Brings together several data sets to help people visualize our Milky Way galaxy in various wavelengths. It has an interface that caters to non-astronomers. Provides a lot of information concerning cosmic and heliospheric science. Gamma rays are billions of times more energetic than visible light. Operated from to With GLAST, astronomers will study how black holes can accelerate jets of gas outward at great speeds.
Physicists will be able to study subatomic particles at energies far greater than those seen in ground-based particle accelerators. Cosmologists will gain valuable information about the birth and early evolution of the Universe. High resolution grating spectra can be obtained for hundreds of stars. Since higher energy X-rays are capable of penetrating gas and dust, emission from the center of our Galaxy is clearly seen, and brighter X-ray sources in other galaxies and quasars have also been imaged.

It was operational for almost 18 years, The instruments included three coaligned Ultraviolet UV telescopes. A follow-up flight, the Astro-2, flew aboard the space shuttle Endeavor between March 2, and March 18, Expected to be ready in This survey uses larger and much more sensitive detectors than the last major near-infrared sky survey, performed over 30 years ago. This should provide direct answers to immediate questions on the large-scale structure of the Milky Way and the Local Universe.
During its expected 2. It is scheduled for launch in This will carry cameras and spectrographs sensitive to infrared radiation.
IRAS discoveries included a disk of dust around the star Vega, six new comets, and very strong infrared emission from interacting galaxies. Each of the three instruments carried onboard yielded major cosmological discoveries. Will investigate the cosmic microwave background radiation at much higher spatial resolution and sensitivity.
The history of the facility goes back to They have the worlds first giant radio telescope -- the Mk I.
ABOUT THE MAGAZINE
It is held every summer at Breezy Hill, in Springfield, Vermont. Provides resources for instructors of introductory astronomy classes. The sections include: labs, planetarium programs, activities, teaching methods, lecture resources, sample exams, and more. The software section describes the software programs that can be downloaded to student computers. Suitable for high school and college classes, and many of the programs are adapted for non-science majors.
Used by many educators to get students interested in science. Good place to start learning about astronomical concepts and terms. This is an interesting and fun way for people to learn more about astronomy.
