Greenland’s forbidding environment, at the outermost boundary of the European and North American world, have long made it one of the strangest places on earth.

Studying CMEs – massive fireballs that blow out of the Sun’s outermost corona layer – is one of the most important scientific objectives of India’s maiden solar mission.

The brain's functional properties arise from the varied cell types within its cortex, the outermost layer responsible for many complex mental tasks.

The difference between the speed of the fast and slow solar wind is thought to be due to the different areas of the Sun's corona, the outermost layer of its atmosphere, that they originate from.

In a paper appearing in Nature, researchers at MIT, the University of Edinburgh, and elsewhere find that the sun's magnetic field could arise from instabilities within the sun's outermost layers.
