Earth’s magnetic field, generated by movements within its molten iron core, serves as a protective shield against solar winds ...

A vast 500,000-mile-wide coronal hole has opened in the Sun's atmosphere. The area measures over 62 times ... There may also ...

The northern and southern lights, auroras visible from the poles, glow with a range of different colored lights. Here's the reason for each of those colors.

This, they claim, means it must have originated in the highly magnetized region that surrounds a star: the magnetosphere ... their apparent brightness is more affected by the Earth’s atmosphere than ...

Like a snowflake or a fingerprint, each aurora is unique. They appear as ribbons of light, ranging over the whole color spectrum. Each event is a one-time-only light show across the night sky. While ...

The Solar Wind Magnetosphere Ionosphere Link Explorer (SMILE) is a joint mission between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS) which aims to study the ...

Generated by the churning molten metals in Earth’s core, the magnetosphere shields the planet from harmful solar radiation and keeps solar winds from stripping away Earth’s atmosphere. Because the ...

As a result of the lack of solar wind, the pressure decrease caused Mars's atmosphere and magnetosphere to expand by thousands of kilometers, tripling in size. It also sent a supersonic shockwave ...
