... 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. ...

... A Distant Cluster of Galaxies . ... Oddly - most of them are spiral galaxies. This rich cluster of galaxies, named CL 0939+4713, is almost half way across the visible universe. ... Discovered in 1963, astronomers were astounded that such objects could be visible across billions of light-years, as this implies they must emit prodigious amounts of energy. ...

... White Dwarf Spectra . ... My conception of a white dwarf with a dusty disk. The dust must sublimate and will accrete onto the surface of the white dwarf, possibly through streamers of gas that follow the white dwarf's magnetic field lines. As in Saturn's rings, there might be streaks in the dust due to material that is darker than the surrounding dust, or perhaps caused by shadows of rocky bodies with sizes larger than the scale height of the disk. ...

... Dark Matter Ring Modeled around Galaxy Cluster CL0024+17 . ... It is the relatively weak distortions of the many distant faint blue galaxies all over the image, however, that indicates the existence of the dark matter ring. ... A hypothesis for the formation of the huge dark matter ring holds that it is a transient feature formed when galaxy cluster CL0024+17 collided with another cluster of galaxies about one billion years ago, leaving a ring similar to when a rock is thrown in a pond. ...

It is possible to piece together the processes that have shaped the observed characteristics of a galaxy by studying its stars in detail. The Large Magellanic Cloud (LMC) is an excellent candidate for this type of study because of its favourable viewing angle and ongoing star formation. I present the results of high-resolution VLT/FLAMES observations of ~80 red giant stars around star cluster NGC 1846, located in the disc of the LMC. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...
