... Since planets are expected to form out of the material in disks around young stars, the formation of a planet will thoroughly alter the structure of the circumstellar disk of their host star, forming significant gaps in the radial distribution of matter around the star. Additionally, processing of solids (annealing/crystallization) and changes in the overall gas/dust ratio are thought to happen during the planet formation process and are believed to alter the observational signature of the disk. ...

Armagh Observatory, 28 May 2004: A very rare astronomical event occurs during the morning of the 8th June this year, when the planet Venus crosses the face of the Sun. During the event, known as a 'transit of Venus', the Earth's 'sister' planet Venus will appear as a small black disc, about one thirtieth the diameter of the Sun. The last transit of Venus occurred nearly one hundred and twenty-two years ago, in December 1882. ... Last Revised: 2004 June 4th . ...
