The Kaggle galaxy zoo challenge is an example of a problem begging for ideas from outside the field. Sander Dieleman, with a background in deep learning and feature learning, bravely stepped forward, creating an image classifier utilising convolutional neural networks; his full solution is described fluently here. These kinds of techniques could be applied ...


If you have good knowledge of software development and pattern recognition, there are several problems that you could assist in solving. Much of observational astronomy requires long time series data, and removing the noise from this data. I have just left the field where some colleagues are trying to develop some software to use image subtraction techniques ...


This must be what you are looking for, "Tabulae Rudolphinae". Tycho Brahe's star catalogue and planetary data published by Kepler in 1627 .


The page I referred to in my question lists the reference Brahe, Tycho. Edited by I.L.E. Dreyer Tychonis Brahe Dani Opera Omnia. (in Latin) Vol 1-15. 1913-1929. (contains the observations in Tycho's notebooks) Now this page is supposed to be an electronic version of Tycho's book. It says Opera omnia, edidit I.L.E. Dreyer in the big title at the ...


It depends a bit on how precise you would want to be. A very good discussion on how to calculate the orbits of solar system objects is given in the book by Jean Meeus, Astronomical Algorithms (1999), which is at an advanced amateur level. At professional level you have the Explanatory Supplement to the Astronomical Almanac by Urban and Siedelmann. For ...


There are more stars and galaxies but not necessarily more information. You might choose to measure the information content in terms of photons received, in which case, for a given star/galaxy, this decreases as the inverse square of the distance, so the two effects cancel out. Astronomy is a constant struggle with the tension between these two competing ...


This is the reply I got from the US Naval Observatory itself: No, we do not have that transformation in NOVAS. Generally, altitude and azimuth are not determined to very high accuracy, so using them to obtain RA and Dec, which are much more precisely defined and measured, does not make a lot of sense.
