Forget Rome. Ignore Madrid. Overlook tropical islands. Cash in your frequent flier miles and book a cruise to far-flung, exotic exoplanets.
Looking for another Earth? An international team of researchers has pinpointed which of the more than 4,000 exoplanets discovered by NASA's Kepler mission are most likely to be similar to our rocky home.
KU Leuven astronomers have shown that the interaction between the surface and the atmosphere of an exoplanet has major consequences for the temperature on the planet. This temperature, in turn, is a crucial element in the ...
Earth is situated right in the middle of our Sun's habitable zone and it's a comfortable place for life. We enjoy a relatively stable climate and the right amount of warmth to allow liquid water.
The team operating NASA's Curiosity Mars rover is taking steps to return the rover to full activity following a precautionary stand-down over the Fourth of July weekend.
If conditions had been just a little different an eon ago, there might be plentiful life on Venus and none on Earth.
