False-colour Skylab image of a solar prominence
Numéro d’image : 11884114
| False-colour extreme ultraviolet image of the solar disc & a huge solar prominence,recorded by the Skylab space station in 1973. The disc of the Sun (left) was recorded at the 30.4 nanometre wavelength of radiation from helium atoms stripped of 1 electron. These atoms occur in the lower atmosphere,so the disc shows the clumpy distrib- ution of helium gas just above the Sun's visible surface - along with the prominence projecting half a million km (almost 50 Earth-diameters) at top. The "ghost" images to left & right of the full disc were recorded at nearby ultraviolet wavelengths & show radiation from other atoms in the solar atmosphere. (More details on request). This picture is Fig. 2.1 in THE NEW ASTRONOMY & is described more fully on page 15 of that book | |
