Water changes everything about the way a planet works.” With those words, Graham Pearson, a foremost expert on deep Earth ...

Despite having radically different atmospheres, Mars and Earth seem to have similar cloud patterns, hinting that the features may form in much the same way. The observations, obtained by the ...

(High pressures within the Earth cause material to freeze at high temperatures.) This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic ...

A cell's fluorescence dimming as a magnetic field passes over it. The Earth's magnetic field is a result of the movement or convection of liquid iron in the outer core. As the liquid metal in the ...

(High pressures within the Earth cause material to freeze at high temperatures.) This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic ...

A paper detailing the convection cell observations has been published in the journal Nature. The video below zooms in on π1 Gruis from the perspective of Earth.

Here on Earth, for example, convection in the outer core is believed ... This results in the formation of a pattern of convection cells surrounding the bulb’s axis of rotation. By carefully tuning ...

can last up to 24 hours and have diameters greater than Earth’s. In 1968, scientists theorized that even longer-lived and larger convection cells, big enough to span the entire convective zone ...

The image covers an area of 36,500×36,500 km 2 on the Sun’s surface – which is about 2.6 times the surface area of Earth. Despite the huge area ... The granular structures in the image are convection ...
