Growing magnetic fields in deep space: Just wiggle the plasma

Contrary to what many people believe, outer space is not empty. In addition to an electrically charged soup of ions and electrons known as plasma, space is permeated by magnetic fields with a wide range of strengths. Astrophysicists ...

Flying focus: Controlling lasers through time and space

Scientists have produced an extremely bright spot of light that can travel at any speed—including faster than the speed of light. Researchers have found a way to use this concept, called "flying focus," to move an intense ...

Taming plasmas: Improving fusion using microwaves

We all know microwaves are good for cooking popcorn, but scientists have recently shown they can also prevent dangerous waves in plasmas and help produce clean, nearly limitless energy with fusion. Fusion takes place when ...

Inside job: A new technique to cool a fusion reactor

Fusion offers the potential of near limitless energy by heating a gas trapped in a magnetic field to incredibly high temperatures where atoms are so energetic that they fuse together when they collide. But if that hot gas, ...

Laboratory experiments probe the formation of stars and planets

The cosmos is a void dotted with stars and an ever-increasing number of newly-observed planets beyond our solar system. Yet, how these stars and planets formed out of clouds of interstellar dust and gas remains mysterious.

A stellar achievement: Magnetized space winds in the laboratory

New insights have been gained about stellar winds, streams of high-speed charged particles called plasma that blow through interstellar space. These winds, created by eruptions from stars or stellar explosions, carry with ...

Scientist explores a better way to predict space weather

Findings recently published by a Southwest Research Institute (SwRI) space scientist shed new light on predicting the thermodynamics of solar flares and other "space weather" events involving hot, fast-moving plasmas.
