Ten questions driving the geological and planetary sciences were identified today in a new report by the National Research Council. Aimed at reflecting the major scientific issues facing earth science at the start of the 21st century, the questions represent where the field stands, how it arrived at this point, and where it may be headed."With all the advancements over the last 20 years, we can now get a better picture of Earth by looking at it from micro- to macro-perspectives, such as...

Gas-giant planets like Jupiter and Saturn form soon after their stars do, according to new research. Observations from NASA's Spitzer Space Telescope show that gas giants either form within the first 10 million years of a sun-like star's life, or not at all. The study offers new evidence that gas-giant planets must form early in a star's history. The lifespan of sun-like stars is about 10 billion years. Ilaria Pascucci of the University of Arizona Steward Observatory in Tucson led a team of...

Scientists at The University of Manchester have unveiled new research which shows how exploding stars may have helped to create the earth. The discovery was made during a unique research project examining how some dead stars re-ignite and come back to life. Professor Albert Zijlstra's study of Sakurai's Object - the only star which has been observed re-igniting in modern times - has led him to conclude that 5% of the carbon on earth may have been come from stardust expelled by stars exploding...

RAS -- How many planets like the Earth are there among the 130 or so known planetary systems beyond our own? How many of these "ËœEarths' could be habitable? Recent theoretical work by Barrie Jones, Nick Sleep, and David Underwood at the Open University in Milton Keynes indicates that as many as half of the known systems could be harbouring habitable "ËœEarths' today. Unfortunately, existing telescopes are not powerful enough to see these relatively small, distant...
