... Bringing news from across the Universe to children all around the world . ... Yet, all of these things are made from the same stuff: chemical elements. ... In total, there are only 118 chemical elements. That means that everything in your room and everything that we can see on Earth is made up from different amounts of some of these chemical elements. ... There might be some extra chemical elements out there, but astronomers only know about 118 chemical elements so far. ...

... In most astronomical observations the image intensity consists of contributions from both object and sky background. Depending on the complexity of the field and the type of object, different methods are used to estimate and subtract the background intensity. ... Non--linear filters are often used to remove stellar images and other sharp features (see Section ) while extended objects are very difficult to eliminate automatically. ...
