1) Ptolemy 2) Copernicus 3) Galileo 4) Orbits of planets are ellipses with the sun at the focus… the line joining the planet to the sun sweeps out equal areas at equal times… the square of the orbital period is directly proportional to the cube of the average distance from the sun to planet 5) Robert Goddard 6) Wernher Von Braun 7) 1957 8) Explorer 1 9) Yuri Gagarin 10)G2V 11)Fusion between hydrogen and helium atoms 12)Photosphere 13)Core, radiation zone, convection zone 14)Photosphere, Chromospere, Trasition region, corona 15)Chromospheres 16)Temperature rises exponentially and inexplicably 17) Coronal streamer- region of high density plasma trapped in closed magnetic field lines: hole-region of low density plasma that is emitted in areas of open field lines 18)Sharp, brief jets of plasma that spew out in between supergranules 19)Prominences are regions of dense plasma that are enclosed in long magnetic field loops and then burst through the magnetic field line with plenty of force 20)Sunspots are dark because they are regions where the magnetic field line doesn’t allow convection of heat to occur at the surface and the cooler region doesn’t emit light 21)11 years 22)The Babcock solar Dynamo; as the sun rotates, the magnetic field rotates faster at the equator and slower at the poles creating an irregularity in the shape of the magnetic field 23)Magnetic 24)Bremsstrahlung Radiation, particles are accelerated after breaking out of a flare and are slowed down by being influenced by positively charged ions, this causes the lost “braking” energy to be given off as a “hard” xray 25)Size of active region/brightness of radiation 26)Plasma 27)Navierre Stokes and Maxwell equations 28)22 years

29)Sun’s gravitational field wasn’t strong enough to hold back the corona 30)Observed two comet tails, ion tail from solar wind and dust tail from movement of comet 31)Fast because it isn’t being held back by closed magnetic fields 32)Fluid pressure/magnetic pressure (solar wind/solar prominence) 33)Case 1 Plasma beta where the fluid pressure drives the plasma motion and the magnetic pressure is linked to follow and lag with the magnetic pressure and create that “frozen in” conclusion 34)Radial motion of solar wind and azimuthal rotation of the sun 35)As the sun rotates the heliosphereic current sheet is warped because of the constantly changing magnetic field. . the points where the sheet moves from above to below the heliosphereic equator or vice versa creates sectors 36)The stronger areas that emit solar wind catch up to the area where the solar wind is quieter and because some waves are moving slower than others, they compress and “co-rotate” 37)The point where interstellar wind is deflected by the suns magnetic field 38)Explore interplanetary space at high solar altitudes 39)Studies high energy radiations from solar flares 40)ACE/SOHO 41)Inner core, outer core, mantle, crust 42)Chemical differentiation, radiation, and the earths rotation react with the
