As solar wind blows, our heliosphere balloons

What happens when the solar wind suddenly starts to blow significantly harder? According to two recent studies, the boundaries of our entire solar system balloon outward—and an analysis of particles rebounding off of its ...

Study shows how Earth slows the solar wind to a gentle breeze

As Earth orbits the sun at supersonic speed, it cuts a path through the solar wind. This fast stream of charged particles, or plasma, launched from the sun's outer layers would bombard Earth's atmosphere if not for the protection ...

Army's new find lowers accidental stockpile detonation

Scientists at two major national laboratories have demonstrated a new method for testing explosives stored in weapons stockpiles, a step they say will help reduce accidental detonation and ensure the weapons perform as expected.

Three NASA satellites recreate solar eruption in 3-D

The more solar observatories, the merrier: Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the Sun—an effort made possible only by combining data from ...

Cosmic bow shocks

Imagine an object moving at super-sonic speed. This object, as it moves through a medium, causes the material in the medium to pile up, compress, and heat up. The result is a type of shock wave, known as a bow shock.

Plants feel the heat

It's not just humans and animals that suffer when the mercury rises, plants feel the heat too. Heat stress is a major issue in agriculture and can significantly reduce crop yield. Even small increases in temperature can affect ...
