In a new study, NASA has revealed that they have spotted a Man-made barrier around Earth that disallows high-energy space radiation from entering the planet.

A large volcanic eruption may have triggered the first mass extinction of life, in which nearly 80 per cent of the species were lost, a study has shown.

Heavy rain on Mars reshaped the planet's impact craters and carved out river-like channels on its surface billions of years ago, says a study. Changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet's surface as we see on Earth, said the study published in the journal Icarus.

Astronomers have discovered a "puffy planet" orbiting a star 320 light years from Earth which may hold opportunities for testing atmospheres that would be useful when assessing future planets for signs of life.

The US Air Force's X-37B space plane returned to Earth on Sunday after completing a secret space mission that lasted nearly two years.

Large impacts can be followed by intense, long-lived and explosive volcanic eruptions -- not just craters, new research has found. The researchers studied rocks filling one of the largest preserved impact structures on the planet, located in Sudbury, Ontario, Canada.

NASA Cassini spacecraft has send some farewell pictures from Saturn rings in which both Earth and its moon are visible like two shiny dots at a distance of nothing less than 870 million miles.

Google Doodle on Wednesday celebrates final phase of 20-year-old Cassini Spacecraft orbiting Saturn's Moon, Titan.

NASA's Cassini spacecraft has completed its last close brush with Saturn's hazy moon Titan and is now beginning its final set of 22 orbits around the ringed planet.

NASA has released a new image of earth clicked from Saturn's Icy Rings, where it can be seen only as a point of light. The image has been clicked by NASA's Cassini spacecraft from the distance of 870 million miles from the icy rings of Saturn.
