In astronomy, elements other than hydrogen and helium are called metals. While that might make your high-school chemistry teacher cringe, it makes sense for astronomers. The two lightest elements were the first to appear ...
Producing energy on Earth through nuclear fusion, the type of reaction that powers the sun, has proven to be a major challenge. The extreme conditions needed for such a reaction require the walls of a nuclear fusion device ...
To produce commercial energy, future fusion power plants will need to achieve temperatures of 100 million degrees C. To do so requires careful control of the plasma. In a study published in the journal Nuclear Fusion, researchers ...
Scientists have conducted laboratory experiments at Lawrence Livermore National Laboratory (LLNL) that provide new insights on the complex process of pressure-driven ionization in giant planets and stars. Their research, ...
The massive, star-forming interstellar cloud Lupus 3 is captured with the 570-megapixel US Department of Energy-fabricated Dark Energy Camera at NSF's NOIRLab's Cerro Tololo Inter-American Observatory in Chile. The dazzling ...
Better understanding the formation of swirling, ring-shaped disturbances—known as vortex rings—could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source.
At the end of a star's life, nuclear fusion ceases, and the resulting pressure is no longer sufficient to counteract the gravitational force. This collapse can lead to the formation of neutron stars, which are composed of ...
The idea that energy is a fundamental driver of societal progress has led to the concept that a civilization's level of technological development can be measured by its ability to harness and use energy. Based on this, Russian ...
The sun's rotation produces changes in its magnetic field, which flips completely every 11 years or so, triggering a phase of intense activity. Solar flares—huge eruptions from the surface of the sun lasting minutes or hours—emit ...
In a little over four years, NASA's Dragonfly mission will launch into space and begin its long journey towards Titan, Saturn's largest moon. As part of the New Frontiers program, this quadcopter will explore Titan's atmosphere, ...
