Albedo used in astronomy are the (V-band) geometric albedo (measuring brightness when illumination comes from directly behind the observer) and the Bond albedo (measuring total proportion of electromagnetic energy reflected). Their values can differ significantly, which is a common source of confusion. In detailed studies, the directional reflectance properties of astronomical bodies are often expressed in terms of the five Hapke parameters which semi-empirically describe the variation of albedo with phase angle, including a characterization of the opposition effect of regolith surfaces. The correlation between astronomical (geometric) albedo, absolute magnitude and diameter is: formula_7, where formula_8 is the astronomical albedo, formula_9

He concluded that "the stretches of notes and rhythms don't become weary or monotonous at any point of the album", and that "intention of conjuring up the vastness and immensity of space is soundly accomplished". Henri Stirk from Background Magazine rated the 2013 edition by Esoteric Recordings 4/5 stars.
