Asteroid impact mission targets Didymos ESA's proposed Asteroid Impact and Deflection Assessment mission now has a target: asteroid Didymos. The recent Russian meteor and, on the same day, our planet's close encounter with an even larger chunk of celestial debris underline the need for us to lea...

Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid (4) Vesta and as such are part of the HED meteorite group. They are the most common achondrite group with well over 100 distinct finds at present. Eucrites get their name from the Greek word eukritos m...

Title: Effects of a Companion Star on Slow Nova Outbursts -- Transition from Static to Wind Evolutions Authors: Mariko Kato (Keio Univ.), Izumi Hachisu (Univ. of Tokyo) Two types of nova evolutions can be realised in low mass white dwarfs of ~0.5-0.7 M_sun, i.e., an evolution with optically thick w...

The varying speed of light cosmology has been proposed independently by Jean-Pierre Petit from 1988 and then John Moffat in 1992 and the two-man team of Andreas Albrecht and João Magueijo in 1998 to explain the horizon problem of cosmology and propose an alternative to cosmic inflation. In Petit's...
