WASHINGTON, Aug 24 (Reuters) - The solar wind is a ubiquitous feature of our solar system..

"We suggest that these jets could actually be a major source of mass and energy to sustain the solar wind," said solar physicist Lakshmi Pradeep Chitta of the Max Planck Institute for Solar System Research in Germany, lead author of the research published in the journal Science...

"Unlike the wind on Earth that circulates the globe, solar wind is ejected outward into interplanetary space," Chitta said.. "Earth and the other planets in the solar system whiz through the solar wind as they orbit around the sun..

The data for the study was obtained last year by one of the three telescopes on an instrument called the Extreme Ultraviolet Imager aboard the Solar Orbiter, a sun-observing probe built by the European Space Agency and the U.S. space agency NASA that was launched in 2020..
