The proposed origin of our solar system with planet migration

Two new models to explain the origin and history of our solar system are reviewed from a creation perspective, the Grand Tack model and the Nice model. These new theories propose that the four outer…

Constraining dark matter sub-structure with the dynamics of astrophysical systems

The accuracy of the measurements of some astrophysical dynamical systems allows to constrain the existence of incredibly small gravitational perturbations. In particular, the internal Solar System…

Panspermia : the survival of micro-organisms during hypervelocity impact events

The research presented shows that the micro-organisms Nannochloropsis oculata phytoplankton and tardigrade Hypsibius dujardini can be considered as viable candidates for panspermia, and it is demonstrated that the organisms can survive a range of impact velocities, although survival rates decrease significantly at higherVelocities.

The Pessimistic Induction and The Epistemic Status of Scientific Theories

Virtually all prominent critics of the Pessimistic Induction have so far assumed that in order to defeat the argument, one must show that there is a degree of continuity in the history of science at…

On the Relation Between Models and Hypotheses and the Role of Heuristic Hypotheses in the Construction of Scientific Models

In our understanding of model-based scientific practice, it has become unclear what the role of hypotheses is. Many take mo- dels and hypotheses to be more or less on the same footing; others take…

50 years on: legacies of the Apollo programme

On the 50th anniversary since humans first set foot on the Moon, John Pernet-Fisher, Francesca McDonald, Ryan Zeigler and Katherine Joy take a look back at the legacies of the Apollo programme.

Iron meteorites as remnants of planetesimals formed in the terrestrial planet region

It is shown that the iron-meteorite parent bodies most probably formed in the terrestrial planet region, and it is predicted that some asteroids are main-belt interlopers and a select few may even be remnants of the long-lost precursor material that formed the Earth.

Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets

This model not only naturally explains the Late Heavy Bombardment, but also reproduces the observational constraints of the outer Solar System.

Mg isotope evidence for contemporaneous formation of chondrules and refractory inclusions

The presence of excess 26Mg resulting from in situ decay of the short-lived 26Al nuclide in CAIs and chondrules from the Allende meteorite is reported, indicating that Allende chondrule formation began contemporaneously with the formation of CAIs, and continued for at least 1.4 Myr.

Origin of the Moon in a giant impact near the end of the Earth's formation

This work reports a class of impacts that yield an iron-poor Moon, as well as the current masses and angular momentum of the Earth–Moon system, and suggests that the Moon formed near the very end of Earth's accumulation.

Late formation and prolonged differentiation of the Moon inferred from W isotopes in lunar metals

The Moon is thought to have formed from debris ejected by a giant impact with the early ‘proto’-Earth and, as a result of the high energies involved, the Moon would have melted to form a magma ocean.…

The Origin of Short-lived Radionuclides and the Astrophysical Environment of Solar System Formation

Based on early solar system abundances of short-lived radionuclides (SRs), such as 26Al (T1/2 = 0.74 Myr) and 60Fe (T1/2 = 1.5 Myr), it is often asserted that the Sun was born in a large stellar…

Origin of the orbital architecture of the giant planets of the Solar System

This model reproduces all the important characteristics of the giant planets' orbits, namely their final semimajor axes, eccentricities and mutual inclinations, provided that Jupiter and Saturn crossed their 1:2 orbital resonance.
