The NASA Kepler mission, launched in early March, is designed to search for Earth sized planets around nearby stellar systems. Successful commissioning of the spacecraft by mid-May saw the start of the search with early results anticipated to reveal observations of Jupiter sized planets.
Further, results were not expected until early next year. So it was surprising, therefore, for NASA to announce a press conference on Kepler findings for Thursday 6 August. Undoubtedly such an announcement opens a multitude of possibilities on what Kepler has seen.
