Jupiter and Io from The Hubble Space Telescope Introduction: The Skokie Valley Astronomers are a group of amateur astronomers located in the Northern suburbs of Chicago, IL. We meet on the second Friday of every month, 8:00 P.M., at Ryerson Nature Center, 21950 Riverwoods Rd., Riverwoods, IL 60015. Our club is fairly small, with about 40 members, so our meetings are somewhat informal, but we do have a speaker or presentation at every meeting. Weather permitting, members with telescopes set them up for observing following the meeting. New members at any interest level from beginner to advanced amateurs are always welcome. Interested non-members are welcome to attend our meetings. We are a member of the Astronomical League.

Astronomers using a radio telescope system to make the most precise measurement ever of the solar system orbit found that it takes the sun and its family of planets 226 million years to circle the center of its home galaxy. That means that the last time the sun was at this point in its orbit of the Milky Way, dinosaurs ruled the world and human beings were not yet on the scene. The new measurement is the most precise value ever determined for one of the fundamental motions of the Earth and its sun, said James Moran of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. He spoke Tuesday at the national meeting of the American Astronomical Society.

There are thousands of us out there! Each is unique. Everyone has different interests. Some like to take pictures with an "old fashioned" SLR camera and some like using advanced Charged Coupled Devices (CCD). There are even a very few of us that are fortunate enough to get paid for studying the universe. Some of us just like to look up to the night sky and wonder what makes it all go.

Newswatch Last Updated: Wednesday, 9 April, 2003, 02:48 GMT 03:48 UK Email this to a friend Printable version Cosmic link to stone circles By Helen Briggs BBC News Online science reporter Stone Age people in Ireland appear to have built tombs based on a detailed knowledge of how the Sun moves across the sky during the year. Sunlight strikes the inside of the tomb at the autumn equinox ( Image: knowth.com Tombs at the archaeological site of Loughcrew in County Meath align with the rising Sun at the spring and autumn equinoxes. The inside of the chambers are spectacularly illuminated by a shaft of sunlight at dawn on these days, said Frank Prendergast of the Dublin Institute of Technology. It suggests settlers in the area some 5 to 6,000 years ago knew the yearly cycle of the Sun and perhaps centred their lives around it. Tombs found elsewhere in Ireland have been found to point towards the rising Sun at the summer and winter solstices. At these times, the Sun reaches its most northerly and southerly points in the sky, which can be easily observed from any place on Earth.

Original Version: PASP, November 1994. Abstract: The amount of data produced by large observational facilities and space missions has led to the archiving and on-line accessibility of much of this data, available to the entire astronomical community. This allows a much wider multi-frequency approach to astronomical research than previously possible. Here we provide an overview of these services, and give a basic description of their contents and possibilities for accessing them. Apart from services providing observational data, many of those providing general information, e.g. on addresses, bibliographies, software etc. are also described. The field is rapidly growing with improved network technology, and our attempt to keep the report as complete and up-to-date as possible will inevitably be outdated shortly. We will endeavor to maintain an updated version of this document on-line.

But these symbols speak volumes about the size and fate of the cosmos—and the rapidity with which astronomers have come to embrace one of the most bizarre discoveries ever made. Just 2 short years ago, two teams of astronomers presented the first evidence that we live in a runaway universe, driven to expand at a faster and faster rate.

96. Julian Day Numbers An explanation of the Julian day number system used by astronomers and calendricists. http://www.hermetic.ch/cal_stud/jdn.htm

Julian Day Numbers by Peter Meyer Introduction The Julian Period Julian Day Number Astronomical Julian Day Number ... Conversion Algorithms 1. Introduction Just as a Gregorian date is a date in the Gregorian Calendar, a Julian date is a date in the Julian Calendar. (For more on these calendars see The Julian and Gregorian Calendars ). Astronomers sometimes use the term "Julian date" in another sense, according to which it is related to what is called a "Julian day number". Such a use of the term "Julian date" makes it ambiguous, but the meaning is usually clear from the context. In this article the notion of the Julian day number will be explained, along with various meanings of the term Julian date. According to the system of numbering days called Julian day numbers , used by astronomers and calendricists (those who study calendars, unfortunately not for a living), the temporal sequence of days is mapped onto the sequence of integers, -2, -1, 0, 1, 2, 3, etc. This makes it easy to determine the number of days between two dates (just subtract one Julian day number from the other). For example, a solar eclipse was seen at Nineveh on June 15, 763 B.C. (Julian Calendar), according to the Assyrian chronicles in the British Museum, and a lunar eclipse occurred there on the night of April 14-15, 425 B.C. (Julian Calendar). (The
