This web site gives access to up-to-date meteorological forecasts in order to provide astronomers with information to plan their sky observation activities. The forecasts cover North America and are produced by the numerical weather prediction models that execute at the Canadian Meteorological Centre. The following forecast parameters are available in real time: forecasts of cloud, surface winds, temperatures and humidity as well as more specific parameters such as seeing forecasts and sky transparency. Cloud forecast Cloud forecasts at hourly intervals up to 48 hours. These forecasts can be interpreted in the same way as satellite pictures in the visible spectrum. Seeing forecast Seeing forecasts at 3-hourly intervals up to 48 hours. The “seeing” is the term used in astronomy to quantify the steadiness or the turbulence of the atmosphere. The detailed observation of planets, planetary nebulae or any celestial object requires excellent seeing conditions. Sky transparency forecast Sky transparency forecast at hourly intervals up to 48 hours.
15+ Sites for Backyard Astronomers
The stars have always fascinated mankind. Telescopes aren’t exactly cheap though, so how do you know which ones are worth the money? Where do you find charts that show you which stars are which? How do you know when the weather will be best suited for viewing? Luckily there are numerous resources on the Web to help you find all the astronomy answers and recommendations that you need.
We’ve gathered up over 15 that will help anyone become a backyard astronomer.

Astronomers have discovered thousands of planets circling distant stars. This is the hottest field in astronomy. How do you find exoplanets and what are they like? Have we discovered a Second-Earth? Looking for a romantic Saturday night out under the stars? Come see what the Observatory is like after hours. You’ll get to use telescopes to view astronomical objects that are not visible until late at night weather permitting.
That night the Moon will be in conjunction with Mars! The program runs rain or shine. If the weather does not permit viewing, we’ll have fun showing you around the universe and behind the scenes at the Observatory. Since it’s invention in September of , the telescope has expanded our views of the universe. We will focus on the earliest designs all the way up to today’s massive and orbiting observatories.

For instance, common language errors that we only see at times are not included in the explanations because they are explained in other general grammars, dictionaries, and handbooks. The LEs strive for consistency in editing those MSs selected for language editing. Nevertheless, there will always be variations in the English found in the Journal as a whole.

Its activities will include establishing a worldwide network of National Astronomy Education Coordinators NAECs , promoting astronomy in national curricula, supporting teachers with evidence-based education research and helping the community with its professional development. The OAE is also intended to facilitate discussion and knowledge sharing within the community, particularly between astronomy education researchers and astronomy education practitioners.
As we get the OAE up and running, further information will appear on this page, and eventually on a dedicated OAE page. Collaborate with us. Open Positions. Find out how to join our team!

Is it possible to date an archaeological site by astronomical means? In theory, the answer is yes, for if we can identify an alignment and the intended astronomical target, measure where the alignment points, and then use modern astronomy to calculate where that event occurred at different times in the past, then we can fit the best date to the alignment.
Stellar alignments would seem to be most promising, because the rising and setting positions of most stars change significantly over the centuries owing to precession. The rising and setting position of the sun at the solstices and the moon at the standstill limits also alter with time, although by much less, owing to the slow change in the obliquity of the ecliptic. In practice, however, astronomical dating is rife with pitfalls. The main one is that we rarely have reliable e.
Where we do have historical evidence, we are likely to know the date fairly accurately already. More often, we are dealing with prehistoric structures where we have no evidence other than the alignments themselves. If we find an alignment that we suspect to be stellar, we can try different stars and different dates to see if any combination fits particularly well. The problem here is that if, say, we are willing to consider the fifteen brightest stars and a five-hundred-year date range, then there is approximately a one-in-three chance that we will be able to find a star and a date to fit any alignment.
It is frighteningly easy, then, to fit a star and a date fortuitously and made all the easier when we consider that only rarely does one single alignment at a particular monument stand out as the obvious astronomical candidate. In order to be fair with the data—one of the most fundamental methodological principles—we should consider all possible alignments.
