NASA spacecraft dives into sun’s corona
What a scene.
For the primary time, a spacecraft has entered the sun’s hostile outer environment, referred to as the corona, and captured scintillating imagery of the surroundings inside. NASA announced the momentous event, achieved by the house company’s pioneering Parker Photo voltaic Probe mission, on Dec. 14.
NASA’s probe has a 4.5-inch-thick protect to guard its cameras and different devices from temperatures that attain some 2,500 levels Fahrenheit. The rushing craft snapped the unprecedented pictures under in April 2021, when it swung 6.5 million miles from the Solar’s floor. Contained in the corona, we will see buildings referred to as “pseudostreamers,” that are lengthy, radiant beams taking pictures out from the solar. The probe handed above, under, and across the streamers.
Within the high row of pictures, NASA defined the pseudostreamers are seen shifting upward, and within the backside row they’re angled downward.

The Parker Photo voltaic Probe is doing rather more than capturing wild photo voltaic scenes. The better mission intends to dramatically enhance scientists’ understanding of the sun’s intense, dynamic exercise, notably its highly effective photo voltaic wind. The photo voltaic wind is a stream of energized particles consistently touring out of the sun’s environment that, throughout house climate storms, can “disrupt every part from our satellites in house, to ship communications on our oceans, to energy grids on land,” writes NASA.
House climate specialists and photo voltaic scientists need to higher grasp photo voltaic winds and even predict when vastly damaging storm occasions would possibly happen.
“Parker’s measurements of the photo voltaic wind, just some million miles from the Solar’s floor, will reveal new particulars that ought to assist make clear the processes that ship it rushing out into house,” NASA explains.
For a lot of the Parker Photo voltaic Probe’s travels across the solar (and within the photo voltaic wind), it barrelled by a “busy barrage of particles.” However issues modified dramatically as soon as the spacecraft entered the corona, although it was solely there for a couple of hours. Every little thing calmed down.
“Passing by the pseudostreamer was like flying into the attention of a storm.”
“Passing by the pseudostreamer was like flying into the attention of a storm,” NASA reported. Within the corona, the sun’s dominant magnetic fields management the motion of particles emanating from the solar, so there’s extra group and fewer chaos.
Within the coming years, the house probe’s journey across the solar will convey it swooping inside 3.8 million miles of our star’s floor. Count on extra intense imagery, and discovery.
“I’m excited to see what Parker finds because it repeatedly passes by the corona within the years to come back,” Nicola Fox, the director of NASA’s Heliophysics Division, said in a statement. “The chance for brand new discoveries is boundless.”
