About Andrew Rushby

Andrew Rushby is a PhD student in the School Of Environmental Science at the University of East Anglia (UEA) in the United Kingdom. Based in the Laboratory for Global Marine and Atmospheric Chemistry (LGMAC), his research is broadly focussed on planetary habitability and modelling the biogeochemical processes taking place both on the Earth and extrasolar planets, and the implications these cycles may have for astrobiology.

  • Habitable Zone Lifetimes of Exoplanets around Main Sequence Stars

    Last week, my first research paper was published in the journal Astrobiology. The paper outlines our method for estimating how long 'habitable' conditions may exist for on planets that have been discovered in the 'habitable zone' - a concept I regularly discuss on this blog and elsewhere. The run-up to its publication has been surprisingly
  • A brief exoplanet update

    It's been a busy couple of weeks for exoplanetary discoveries, but also for me, which explains why I've taken so long getting round to writing about them. On the 28th of August, the Kepler mission announced the discovery of a unique binary star two planet system. The Kepler 47 family consists of a binary pair, a G-type
