Ducks Fall to Auburn on Last-Second Field Goal
GLENDALE, Ariz. -- Auburn running back Michael Dyer never heard any
whistle, so he just kept running - past the tackler who thought he had him down
and deep into Oregon territory.

Dyer broke stride, then took off on a once-in-a-lifetime run in the final minutes,
setting up a short field goal on the last play that led No. 1 Auburn over the No. 2
Ducks 22-19 in the BCS championship game Monday night.

Rocky exoplanet milestone in hunt for Earth-like worlds
By Jason Palmer , BBC News
Astronomers have discovered the smallest planet
outside our Solar System, and the first that is
like Earth by Nasa's Kepler team.
Measurements of unprecedented precision have shown that the planet, Kepler
10b, has a diameter 1.4 times that of Earth, and a mass 4.6 times higher.
However, because it orbits its host star so closely, the planet could not harbour
The Kepler space telescope, designed to look for the signs of far-flung planets,
rst spotted the planet 560 light years away alongside hundreds of other

Kepler relies on the "transiting" technique, which looks for planets that pass
between their host star and Earth. A tiny fraction of the star's light is blocked
periodically, giving a hint that the star has a planet orbiting it. The radius of the
planet correlates to exactly how much light is blocked when it passes.
Follow-up measurements by a telescope at the Keck
observatory in Hawaii confirmed the find of Kepler 10b by
measuring how the planet pulls to and fro on its parent star
as it orbits. This cosmic dance causes tiny changes in the
colour of the starlight that is measured by telescopes.
However, what completed the suite of measurements for the
Kepler team was the use of asteroseismology - a study of distant
stars that is akin to the study of earthquakes on the Earth. The
oscillations that occur within a star - as within the Earth - affect
the frequencies of the light that the star emits in a telltale sign of
the star's size.
