‘Heartbeat’ of Black Holes Solves Decades-Old Mystery of Plasma Jets

by

Fluctuating light from a black hole, observed over 15 years, has revealed more about the way these enigmatic objects feed. First, a structure called a corona forms around the outside of the event horizon. Then, powerful jets of plasma launch from the poles, punching material from the corona out into interstellar space at speeds close … Read more

Fusion Power Experiment in The UK Smashes Its Old Record in Major Step Forward

by

Late last century, the Joint European Torus (JET) near Oxford, UK, churned out 22 megajoules of energy in what was, at the time, a record in fusion power. Now, experimental upgrades have brought the facility into line with the technology anticipated for a major international project, resulting in the production of nearly three times that … Read more

Black hole jet boasts double helix structure molded by powerful magnetic fields

by

An extraordinary galactic jet ejected from a supermassive black hole boasts a corkscrew-like helical structure, new ground-based telescope views reveal. The black hole lies at the center of an elliptical galaxy called Messier 87 (M87), which is located roughly 55 million light-years from Earth. The black hole — the first, and only, black hole ever … Read more
