-Radiocarbon < 14C >in the world's oceans increased sharply between 1950 and 1970 as a result of the atmospheric testing of nuclear weapons. Through comparison with the 14C time series reconstructed from atmospheric measurements and marine carbonates, Kalish, in 1993, used the 14C concentration measured in fish otolith cores as a means of confirming the annulus-based age estimates for some Sout...

Despite the fact that the sun played such a prominent part in the religion and culture of Ancient Egypt it is surprising that there is virtually no mention of solar eclipses, which would not have been understood and so would have been terrifying. This paper discusses a class of inscriptions appearing on a number of artefacts from Deir el-Medina or nearby and also material from the Book of the D...

Introduction: A widely accepted paradigm for the origin of chondrites maintains that chondrites represent the earliest planetesimals to form from the solar nebula and that differentiated bodies formed by the subsequent melting of chondrites. A challenge to this paradigm comes from physical models of accretion that require rapid accretion of ~10 km planetesimals that are then melted by the heat ...

When Saturn was the only known ringed planet, the rings were believed to be as old as the solar system, some 4.5 billion years old in the conventional chronology. The existence of the rings to the present day was taken as evidence of this chronology. In the 1970s and 1980s, other planets were found to have shortlived, rapidly dissipating rings with life times of the order of millennia. Subseque...
