If habitable planets can form in globular clusters and survive for billions of years, life would have time to become complex.
For the first time, astronomers have found compelling evidence that the dust-free gaps surrounding young stars are caused by massive exoplanets.
A low-cost mission could soon be launched to directly observe the exoplanetary system in orbit around Alpha Centauri, one of the solar system's nearest stellar neighbors.
We could find small planets close to Earth using a new technique being tested on our own sun.
Astronomers have found a rocky planet orbiting a small star that is within easy telescope views from Earth.
Recent observations of the gaps in protoplanetary disks surrounding nearby young stars may not be 'proof' of the formation of exoplanets.
Although scientists have long considered oxygen a sign that life exists on an alien planet, new research suggests the element could be produced without it.
Our solar system has some prime locations (besides Earth) for alien life.
