Galaxies are diffuse objects which are imaged against a background of finite brightness and noise. Galaxies which have the maximum contrast with respect to this background are the ones that are first discovered. ... These galaxies have been missed to date but active surveys for them are underway. ... In this page we present several examples of these newly discovered Low Surface Brightness galaxies as well as examples of high surface brightness galaxies. ...

Active region 1158 let loose with an X2.2 flare late on February 15, the largest flare since Dec. 2006 and the biggest flare so far in Solar Cycle 24.
