Back The results of the EUVE survey of the entire sky, conducted by the scanning telescopes, are typically displayed in a variety of ways or projections. On the left hand column, we see the familiar map of the Earth displayed in three projections (Spherical, Cartesian, and Hammer-Aitoff). The advantage of using Cartesian or Hammer-Aitoff projections over Spherical is that we can see the whole Earth at once. Similarly, the whole sky observed by the EUVE satellite can be displayed in a variety of projections, as seen on the right hand column. Astronomers typically use the Hammer-Aitoff projection, which displays the whole sky at once. Next
