Ulysses encounters a different solar wind
Its really exciting how different the solar wind is this time compared with the first orbit, David McComas from the Los Alamos National Laboratory told the 34th ESLAB symposium on the heliosphere...
Viewed from afar our Solar System would have a bright dust disc surrounding the Sun similar to the disc surrounding this star
This image, taken with Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS), shows a dust ring around a star called HR 4796A. The image was taken on March 15, 1998
