A detailed and proficient astronomy site that is both well presented
and easily accessible. Look no further for the latest news regarding
the Sun-Earth environment, including such gems as the current speed of
the solar wind, condition of the sunspot cycle and what to look for in
the night sky at the moment.
Online ~ Another great site for all matters astronomical, this time
provided by the public education and outreach arm of the University of
Texas McDonald Observatory. The site provides a useful astronomical diary,
together with some comprehensive and easily accessible information on
the planets and the stars…
Messenger ~ This site is the first phase of the electronic history
of astronomy, as developed in the UK for the University of Cambridge,
under the auspices of the Department of History and Philosophy of Science.
It pulls few punches when explaining how many key figures in astronomical
history, were also keen astrologers too.
|Stars ~ Think you know about stars? Jim Kaler is Professor Emeritus of Astronomy at the University of Illinois and one way or another since 1997, he has maintained this website as a fitting illustration of his knowledge and enthusiasm for all things celestial. The depth and scope of the information he provides is often staggering…
|Stellar Classification ~ Stars can be categorised according to their spectral characteristics. The spectral class of a star describes the ionization of its photosphere and gives an objective measure of its temperature. What this means is that the colour of the star pinpoints how cool or hot it is, on a scale that runs from dark brown to blue and less than 700 K to over 33,000 K…
in History ~ Sunspot activity follows an eleven year cycle. Many believe that major events can be correlated with the maxima and minima of these solar phenomena. Here you can enter your own birthday and find out whether this date coincided with important solar activity too. You’ll need Java enabled in your browser though.
|Supermoon ~ As we approach the closest full moon to the Earth in a lifetime, the mainstream media is strangely silent, after resurrecting this concept for a number of years. I have recommended Timeanddate.com before, but admire their eagerness to promote some semblance of reality. Also Richard Nolle must be annoyed, he has no monopoly on a term he coined decades ago…
Aurora Page ~ If you are fascinated by the aurora phenomenon,
those spectacularly beautiful displays of light seen otherwise in darkness
and only from extreme latitudes, then this site is definitely for you.
There is a great gallery of images, explanations of why an aurora occurs,
plus links to further information.
|The Constellations ~ Online since 1996 and still regularly updated, this site is the product of one man’s enthusiasm for astronomy and his eagerness to share his knowledge with the world. Of particular interest is the constellations table, which offers a detailed but user-friendly look at what lies in the zodiac belt and also beyond, mainly from the angle of a fascinated amateur.
|The-Moon Wiki ~ This expanding web resource aims to catalogue the features of the lunar landscape. You will find plenty of detailed information about our satellite including maps, data, photographs and links to other erudite studies of every peak, plain, depression and crater on the Moon’s surface. These go from a minor dent, to the South Pole-Aitken basin at 2,500 km across…
Nine Planets ~ A multimedia tour of the solar system. Quite simply
one of the best astronomy sites you will find. Detailed, accurate,
well presented and very readable. Need to know more about those planets
whose effects we’re always considering as astrologers? Look no further than Bill Arnett’s
site, it’s definitely an Internet institution!
|The Planetary Society ~ Founded by Carl Sagan and friends, this is a non-profit-making organisation dedicated to the further exploration of space and then telling everybody about it all. Their site is a great source of information on all matters astronomical, such as the latest rumour that in August 2007 Mars will seem the size of the full moon…
SunTracker ~ This program is part of Diduknow.info, a user-friendly gateway to the treasures of National Museums Liverpool.
In the section covering space, time and sundials you’ll find the Suntracker,
enabling you to simulate the passage of the Sun across the sky, from
rise to set and from any location anywhere in the world.
|The Woman Astronomer ~ Anyone who has studied astrology will tell you about the overwhelming numbers of female students compared with their male counterparts. Female astronomers are a rarer breed and this site celebrates their achievements, with biographies of those who have made a name for themselves and links to help you find out more.
|Tonight’s Sky ~ The York County Astronomical Society is based in Pennsylvania, USA. As a part of their mission to inform and educate they offer this synopsis of what makes good viewing each month, for astronomers old and new. Aimed at a North American audience, these insights are readily adapted to other locations. The sky is not a painting, it’s a movie they explain…
|Torino Scale ~ The Torino Scale ranks the impact hazard of various comets and asteroids, together with the seriousness of collision predictions, by combining probabilities and known damage potentials. Level 3 is worrying, at Level 10 you may not get home for lunch. You’ll be relieved to hear at present, Level 1 is the highest that is currently assigned.
