This Just In
A ghostly apparition has long been known to follow Saturn moon Enceladus in its orbit around the gas giant. But until now, scientists have had a hard time tracking its source.
The iconic Hubble Space Telescope turns 25 this month, and getting the ball rolling on a life-hunting successor instrument would be a fitting birthday present, one prominent researcher argues.
Humanity is on the verge of discovering alien life, high-ranking NASA scientists say.
The search for alien life doesn't end within the boundaries of our solar system. Scientists are now search for moons orbiting alien planets that might play host to extraterrestrial life.
Astronomers have devised an instrument that could lift the veil of doubt over whether we're alone in the universe.
There is an exclusive group of celestial bodies that are known to possess rings in our solar system -- now a second asteroid-comet hybrid has been found to sport one.
Saturn's icy moon Enceladus is showing definite signs of hydrothermal activity -- similar activity that is found along deep sea vents on Earth where water is heated and minerals are formed.
