Do you need an astronomy tool that does more than just show you pictures? Something that will actually help you with your school work? The Wolfram Astronomy Course Assistant provides a suite of useful tools for helping you in your introductory computational astronomy course. From fact checking to formulas, this app provides a convenient resource to help you complete your homework and study for tests. Answers are computed on the fly using input values you specify.

This app covers the following topics, applicable to college-level Astronomy 120 or any other introductory computational astronomy course:

- Get an overview of constellations, including the effects of proper motion
- Learn the celestial reference points and their location in your sky
- Explore solar system objects, properties, and dynamics
- Study Moon phases, eclipses, and tides
- Examine properties of over 100,000 stars, including distance, parallax, luminosity, and position on the Hertzsprung–Russell diagram
- Learn about the seasons and when meteor showers occur
- Access formulas such as Newton's and Kepler's laws, escape velocity, moments of inertia, angular momentum, and Einstein's famous E=mc^2
- Convert between wavelength and frequency, or find the energy of a photon
- Understand the cosmological effects of universal expansion on light and the gravitational effects of black holes
- Determine the probability of intelligent life on other worlds

The Wolfram Astronomy Course Assistant is powered by the Wolfram|Alpha computational knowledge engine and is created by Wolfram Research, makers of Mathematica—the world's leading software system for mathematical research and education.

The Wolfram Astronomy Course Assistant draws on the computational power of Wolfram|Alpha's supercomputers over a 3G, 4G, or Wi-Fi connection.

Grand Tour Continued ... ->

After 10 months from takeoff, There is now a needed update, which only enhances the package plus there is indeed built-in tour, which continues the experience to a new level.


As a long time user of Mathematica (the first year it was released), and now using Algebra and Calculus Course Assistants as well as WolframAlpha, I have been anxiously awaiting the arrival of Astronomy and now have it on the same day it was released. I *know* that it will provide countless hours of usage. This app is the one I have wanted since it was first announced ... almost anything concerning Math and/or Astronomy I can now solve, or at least get very close to an answer, on my iPad.


Cool Atmospheric Data

The addition of atmospheric data has been a plus for an informative app. The atmospheric aspects will help students to appreciate connections between Earth environmental physics and physical chemistry.

Will there be an addition of radiation exposure to the atmospheric data? Clearly, the Jovian system exposure would be lethal with current shielding technology and the Martian surface exposure will exceed current levels for nuclear power plant workers. Perhaps, a calculation of the solar flux would be sufficient.

Dr. Hooks

Consider updating the atmospheric data for Pluto. It has turned out that spectrometry from an occulting event allowed an analysis of the atmosphere of Pluto. Nitrogen, in a proportion similar to Earth, was evident. The reported information was published in Scientific American (Space & Physics October 03, 2013). This information has been intriguing for the anticipated flyby of Pluto.

Great App

If you enjoy astronomy then you will appreciate this app. Physics equations are calculated using most commonly the MKS system, even here in North America but this being an app of convenience allows you to avoid conversion & just choose what units you would like the answer in. Well put together app with tons of information!
