It is probably a great storm in the planet's atmosphere, which has been initiated by upwelling of clouds from the lower layers into the uppermost regions. The spot began as a small, white feature in Saturn's northern hemisphere and has since developed rapidly so that it now appears to completely encircle the planet's equatorial regions. "Great White Spots" have been seen on Saturn in 1876, 1903, 1933 and 1960 (see below), but the present one seems to be the biggest of them all.</div> </div> <div class="news-readmore">Read more</div> </div>  </a> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <a href="/public/news/eso9013/"> <div class="news-wrapper"> <div class="news-image"> <img class="img-responsive" src="https://cdn.eso.org/images/thumb350x/eso9013a.jpg"> </div> <div class="news-description"> <div class="news-id">eso9013 — Press Release</div> <div class="news-title">At Last: the Enigmatic Centre of the Milky Way Sighted!</div> <div class="news-teaser"><strong>31 October 1990</strong>: Observing with the ESO New Technology Telescope, three European astronomers have discovered two previously unknown celestial objects which are seen in the direction of the mysterious centre of our galaxy, the Milky Way.
