MDI : Michelson Doppler Imager
-Solar Oscillations Investigation
| MDI is used to probe the interior of the Sun by measuring wobbles in the photosphere. The instrument observes the movement of the surface of the sun (in a similar way to GOLF and VIRGO). From these surface movements, we can work out what the inside of the Sun is like! | ![]() |
