A 60-year-old mystery about Sun explosions has been solved by NASA scientists ...

One of the Sun''s many secrets was discovered by NASA scientists.

A type of solar flare that lasts minutes produces enough energy to power Earth for 20,000 years in a timely manner.

Scientists have spent more than half a century trying to understand the meaning of quick magnetic reconnection, and researchers at NASA may have just figured it out, according to a new survey.

New evidence bolsters the pursuit of unpredictable energy.

This study might provide new insight into ways on Earth that may have practical applications, such as nuclear fusion, which aims to harness the same kind of energy as the Sun and the stars. It might also provide more accurate forecasts of geothermal storms, which might affect electronics equipment such as satellites.

"It''s possible that if we understand how magnetic reconnection operates, then we can better predict events that may impact us at Earth, like geomagnetic storms and solar flares," Barbara Giles, a project scientist for NASA and research scientist at NASA''s Goddard Space Flight Center in Greenbelt, Maryland.

"And if we can understand how reconnection is initiated, it will also aid energy research, because researchers might better control magnetic fields in fusion devices," she said.

Scientists from NASA''sMagnetospheric Multiscale Mission (MMS) developed a theory that explains the processes involved in the rapidly-changing magnetic reconnection, the term "very fast" magnetic reconnection. In a paper, the scientists published their findings.

"We finally understand how fast the process of magnetic reconnection is," said Yi-Hsin Liu, the lead author of the study. "We now have a mechanism to demonstrate it."

Magnetic reconnection occurs in plasma, which forms when gas is pressed enough to break its atoms apart, leaving behind negatively charged electrons and positively charged ions. During the process, the plasma rapidly converts magnetic energy into heatand acceleration.

Scientists have been puzzled by the fact that fast reconnection happens at a certain rate that appears to be pretty constant." "But what drives that rate has been a mystery till today," says Giles.

The Solar System''s processes are being investigated.

According to recent research, fast reconnection occurs only in collisionless plasmas, a type of plasma whose particles are spread out so that they don''t collide with one another. In space, most plasma is in this collisionless state.

The Hall effect, which explains the interaction between magnetic fields and electric currents, has accelerated the rapid reconnection, resulting in a constant energy vacuum. The pressures of surrounding magnetic fields have caused the energy vacuum to implode, which violently release huge amounts of energy at a predictable rate.

Plasma is particularly sensitive to magnetic fields, which is why nuclear fusion reactors, called tokamaks, utilize powerful magnets to keep plasma during the fusion reaction. The next step for NASA scientists is to utilize four spacecraft orbiting Earth in a pyramid formation, allowing them to investigate the process ofreconnection in collisionless plasmas at higher resolutions than on Earth. Nuclear fusion, which promises to provide unlimited sustainable energy here on Earth, has pledged to help the world''s worst.
