Much of the radiation energy that makes it through is reflected back into space by clouds, ice and snow and the energy that remains helps to drive the Earth system, powering a remarkable planetary engine – the climate. It becomes the energy that feeds swirling wind and ocean currents as cold air and surface waters move toward the equator and warm air and water moves toward the poles – all in an attempt to equalize temperatures around the world.

The toilet's shortcoming goes unnoticed for many of us, but it is in fact unsustainable, impractical, and unaffordable for 40 percent of the world.

Researchers animated this simulation of a magnetic tornado in the solar atmosphere in order to study how such twisters evolve over time and determine how complex magnetic fields manipulate the Suns ionized gas/plasma.

New NASA data hint that our star is moving too slow to form a bow shock, a structure long thought to protect us from cosmic rays.

The sun has been producing light for about five billion years but where does all its energy come from? The most common idea is that the sun is burning gas - like a giant fireball in the sky. If this were true, the sun would have gone out long ago. So how is the sun actually fuelling itself? It is converting its own mass into energy. By combining protons (the nucleus of hydrogen) into helium, it squeezes some mass into energy - 4.3 billion kg per second. It is Einstein's famous E=mc^2 which gives us the quantitative relationship between mass and energy, where c is the speed of light.

About every 11 years the magnetic field on the sun reverses completely – the north magnetic pole switches to south, and vice versa. This flip coincides with the greatest solar activity seen on the sun in any given cycle, known...

Astronomers at the University of Zürich and the ETH Zürich, together with other international researchers, have found large amounts of invisible "dark matter" near the Sun. Their results are inconsistent with the theory that the Milky Way Galaxy is surrounded by a massive "halo" of dark matter, but this is the first study of its kind to use a method rigorously tested against mock data from high quality simulations. The authors also find tantalizing hints of a new dark matter component in our Galaxy.
