Wolfram Alpha – A Handy Tool for the Casual Astronomer.


We are not quite at that point where you can ask your computer to swing over to the Orion Nebula and take a few shots for next weeks’ astrophotography competition – oh and a cup of Earl Grey, hot, thanks.

But every day seems to get us that little bit closer.

If I want to know where Mintaka is in the night sky, I could start up a planetarium software program like Stellarium, or the legion other planetarium programs and web-based sky mapping sites to choose from.

Seriously, I am holding off on starting my astrophotography career until those Go To computers can make a proper cup of tea.

Anyway my point is, even with all these great information resources around, things are still a bit all over the place. Wouldn’t it be great if there was one place where you could go to find out – well, anything? Wolfram Alpha seems to be taking steps in that direction. It’s kind of a front end interface drawing on a huge virtual warehouse of databases.

As well as the basic search engine, there’s a wiki sideline to all this, notably a set of Wolfram Astronomy demonstration projects here, including a downloadable 3d celestial sphere, a planet database and why not a simplified model of the Big Bang.

Wolfram Alpha can tell me Mintaka is set to rise at 6.01pm local time, it’s 720 light years away and it will set at 6.07 am. And any time I like, I can just hit refresh and get its alt-azimuth position updated in real time. It can do the same for the planets and for the ISS too. Not too shabby.

Also useful for the casual astronomer, if you type in your city, it will give you a weather report – and even a population count if you like. And from there you might find yourself straying further off topic. For example, I now know there are 202,185 people alive named Steve – which is only 1 in every 1,173 people. Hah.

And if you do type in Tea. Earl Grey. Hot.? It says Coming right up. Can’t wait.

  1. The proper query is “tea, Earl Grey, hot” of course. And the Wolfram Alpha reply is “Coming right up.” It’s not too bad after all!

  2. Great article! Good information to get out to everyone.

    Wolfram has a broad range of well built GUI models for different sciences and technologies to use. Even some nice puzzles and optical illusions for kids.

    Many applications have been ported for the ipod and iphone. So you don’t have to run back inside to your desktop, or lug along your laptop when gazing towards your favorite celestial spot.

    For educators… Wolfram even has an area for you. Some nice applications (for all age ranges) to use in the classroom
