The colossal movements of tectonic plates shape our world, influencing the composition of Earth’s atmosphere, the planet’s protective magnetic field and perhaps even the flourishing of life. Now ...

Magnetic crystals provide the earliest evidence yet of the plate tectonics that likely made Earth habitable, pushing its start back by 140 million years.

Helioseismic data traces the solar dynamo to the tachocline about 200,000 km down.

NASA’s twin ESCAPADE spacecraft will uncover how the Sun stripped Mars of its atmosphere. Mars is a very different world ...

One particularly well-known fact about the moon is that it doesn't have much of a magnetosphere to speak of. There's no blanket to protect it from the solar wind ravaging its surface, blowing away its ...

Mercury, Venus, and Mars sit within the same general neighborhood as Earth, yet each has followed a radically different path.

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a ...

The proposed interstellar spacecraft, called Chrysalis, can carry 1,000 people on a one-way trip into deep interstellar space. It was proposed as part.

A huge solar storm struck Mars in 2024, supercharging its upper atmosphere and briefly disrupting spacecraft orbiting the Red Planet.

Mars endured an unprecedented solar superstorm, and European Space Agency (ESA) orbiters, the Mars Express and ExoMars Trace Gas Orbiter, captured the chaos, highlighting the Red Planet’s radiation ...

While Earth experienced dazzling auroras seen as far south as Mexico, Mars faced a very different and far more intense impact.

According to NASA, the solar cycle is a natural process of the Sun, in which the Sun goes through periods of increased and ...
