A Collaborative National Center for Fusion & Plasma Research

Plasma astrophysics

Subscribe to RSS - Plasma astrophysics

A field of physics that is growing in interest worldwide that tackles such astrophysical phenomena as the source of violent space weather and the formation of stars.

Stewart Prager

Stewart Prager was the sixth director of PPPL. He joined the Laboratory in 2009 after a long career at the University of Wisconsin in Madison. At Wisconsin, he led research on the “Madison Symmetric Torus” (MST) experiment and headed a center that studied plasmas in both the laboratory and the cosmos. He also co-discovered the “bootstrap current” there—a key finding that has influenced the design of today’s tokamaks. He earned his PhD in plasma physics from Columbia University.

Ten not-to-be-missed PPPL stories from 2019 — plus a triple bonus!

Arms control robots, a new national facility, and accelerating the drive to bring the fusion energy that powers the sun and stars to Earth. These far-reaching achievements at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) made 2019 another remarkable year. Research at the only national laboratory devoted to fusion and plasma physics — the state of matter that makes up 99 percent of the visible universe — broke new ground in varied fields as vast as astrophysics and as tiny as nanotechnology.

PPPL findings: From new fusion developments to surprises in astrophysics at global plasma physics gathering

More than 155 researchers and students — the largest delegation from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) in recent years — attended the 61st annual meeting of the American Physical Society Division of Plasma Physics (APS-DPP) in Fort Lauderdale, Florida.

A shock to behold: Earthbound scientists complement space missions by reproducing the dynamics behind astronomical shocks

High-energy shock waves driven by solar flares and coronal mass ejections of plasma from the sun erupt throughout the solar system, unleashing magnetic space storms that can damage satellites, disrupt cell phone service and blackout power grids on Earth. Also driving high-energy waves is the solar wind — plasma that constantly flows from the sun and buffets the Earth’s protective magnetic field.

Now experiments led by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) in the Princeton Center for Heliophysics 

Small but mighty: A mini plasma-powered satellite now under construction may launch a new era in space exploration

A tiny satellite under construction at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) could open new horizons in space exploration.  Princeton University students are building the device, called a cubic satellite, or CubeSat, as a testbed for a miniaturized rocket thruster with unique capabilities being developed at PPPL.

Scientists deepen understanding of the magnetic fields that surround the Earth and other planets

Vast rings of electrically charged particles encircle the Earth and other planets. Now, a team of scientists has completed research into waves that travel through this magnetic, electrically charged environment, known as the magnetosphere, deepening understanding of the region and its interaction with our own planet, and opening up new ways to study other planets across the galaxy.
