The flashes resemble more massive explosions such as solar flares and coronal mass ejections but are only a millionth or a billionth the size.<\/p>\n\n\n\n<p>Using observations of 52 campfires, solar physicist Navdeep Panesar and her colleagues tracked these bursts from their beginnings. The team noticed that nearly 80 percent of the campfires <a href=\"https:\/\/agu.confex.com\/agu\/TESS24\/meetingapp.cgi\/Paper\/1493967\" target=\"_blank\" rel=\"noopener\">were preceded by a dark structure made from cool plasma<\/a>, Panesar reported April 9 at the Triennial Earth-Sun Summit.<\/p>\n\n\n<aside class=\"sn-conversion rich-text

The findings suggest these plasma structures are more common than previously believed, Panesar says, and that many solar eruptions \u2014 campfires, jets, flares and mass ejections \u2014 arise in a similar fashion.<\/p>\n\n\n\n<p>Flares and mass ejections occur when magnetic fields of opposite polarities get tangled and cancel one another out, leading to a powerful release of energy. Campfires are believed to be produced via similar mechanisms, though a full understanding has so far eluded researchers.<\/p>\n\n\n\n<p>Since campfires tend to be between half a million and 2.5 million degrees Celsius, they are thought to help heat the sun\u2019s million-degree atmosphere, the corona.
