Solar System planets have been studied for centuries, but the observation of exoplanets is only a few decades old. Consequently, knowledge of exoplanets is considerably more limited than Solar System

Three Decades of Distance Education Astronomy at Athabasca University

The first Astronomy course at Athabasca University was offered in 1989 as a correspondence course, using innovative DOS software on the remote students’ home computers. A Sciencestream course, it

The Natural Science Underlying Big History

No new science is needed to describe cosmic evolution's major milestones at a deep and empirical level; Quantitative models and experimental tests imply that a remarkable simplicity underlies the emergence and growth of complexity for a wide spectrum of known and diverse systems.

Near-infrared absorption properties of oxygen-rich stardust analogs. The influence of coloring metal ions

Context. Several astrophysically relevant solid oxides and silicates have extremely small opacities in the visual and near-infrared in their pure forms. Datasets for the opacities and for the

Avinash–Shukla mass limit for the maximum dust mass supported against gravity by electric fields

Abstract The existence of a new class of astrophysical objects, where gravity is balanced by the shielded electric fields associated with the electric charge on the dust, is shown. Further, a mass

Template-directed polymer assembly is a likely feature of prebiotic chemistry, but the product blocks further synthesis, preventing amplification and Darwinian selection. Nucleic acids are unusual

Orbits of Dust Ejecta From Ceres

The question of whether asteroid ejecta can enter stable orbits about the parent body is examined.
