- Newfound Earth-sized planet too distant to visit
The exploration of the planet known as Alpha Centauri Bb will require technology not currently in existence, say researchers. But if it has sibling planets in a 'habitable zone' scientists may be encouraged to develop the new technology required to such explore new and distant worlds.
Do Pluto's moons pose risks for NASA spacecraft?Scientists are planning a new route for NASA's New Horizons space probe as it approaches a potentially perilous path toward Pluto. They aim to chart a safe, but interesting course.
