The mission discovered packets of very hot material called heat bombs that travel from the sun into the corona.
													
																	The solar corona is a very hot atmosphere surrounding. 
									
	
		
	
																	X ray emissions from the corona show that its temperature is about 2 10 6 k. 
																	The solar corona is a very hot atmosphere surrounding the visible surface of the sun. 
																	Yet the corona is hundreds of times hotter than the sun s surface. 
																	The material in the corona is an extremely hot but very tenuous plasma. 
															
													
									
	
		
	
																	The solar corona is the outermost layer of the sun s atmosphere a very hot halo millions of degrees that in the form of the solar wind extends well past the earth s orbit. 
																	The third layer of the sun s atmosphere is the corona. 
																	The corona is observed in detail during solar eclipses. 
																	The temperature in the corona is more than a million degrees surprisingly much hotter than the temperature at the sun s surface which is around 5 500 c 9 940 f or 5 780 kelvins. 
															
													
									
	
		
	
																	Estimate the number density of particles inthe solar corona. 
																	Although the solar corona is very hot it also has very low density. 
																	A nasa mission called iris may have provided one possible answer. 
																	Estimate the number density of particles in the solar corona. 
															
													
									
	
		
	
																	The corona is in the outer layer of the sun s atmosphere far from its surface. 
																	It appears as white streamers or plumes of ionized gas that flow outward into space. 
																	The gas pressure in the corona is about 0 03 pa. 
																	The solar corona is a very hot atmosphere surrounding thevisible surface of the sun. 
															
													
									
	
		
	
																	The gas pressure in the corona is about 0 03. 
																	The total power emitted in x rays is only about one millionth of the sun s total luminosity so there is enough energy in the sun to heat the corona. 
																	X ray emissions from the corona showthat its temperature is about. 
																	Daytime morphs into a 360 degree dusk and where the sun once hung a black hole punches through the sky wreathed by a white ethereal glow. 
															
													
									
	
		
	
																	During a total solar eclipse it s possible to see clear naked eye evidence of where the sun is in its cycle. 
																	Totality when the moon completely blocks the sun s bright disk affords a brief view of. 
																	Therefore only a small fraction of the total solar radiation is required to power the corona.
