Spaceship Earth

Changes in the sun’s energy output may have led to marked natural climate change in Europe over the last 1000 years.

MIT scientists identify a plasma plume that naturally protects the Earth against solar storms.

NASA's Juno spacecraft flew by Earth in October, building up speed for its journey to Jupiter. The spacecraft also captured an interesting picture of the Earth-Moon system.

Changes in solar activity have contributed no more than 10 per cent to global warming in the twentieth century, a new study has found.

Mysterious cosmic rays constantly bombard Earth from outer space. Now scientists find these energetic particles could limit where life as we know it might exist on alien planets.

Scientists have uncovered new information about the nature of the radiation belts that surround the Earth.

A new study shows that the production of nutrients essential to ocean health on Earth is tied to the cyclic wobbling of our planet on its axis.

Color and black-and-white images of Earth taken by two NASA interplanetary spacecraft on July 19 show our planet and its moon as bright beacons from millions of miles away in space.

Scientists have discovered that sediment in the deep-sea may hold radioactive iron from a supernova that happened 2.2 million years ago. The remnants of the stellar explosion may be preserved in fossilized remains of iron-loving bacteria.

NASA’s Van Allen Probes mission has discovered a previously unknown third radiation belt around Earth. The belts are critical regions for modern society, which is dependent on many space-based technologies.
