Martin Rees Contact Address: Institute of Astronomy Madingley Road Cambridge Tel.: (0)1223 337520 Fax: (0)1223 337523 Email: mjr@ast.cam.ac.uk Martin Rees is Professor of Cosmology and Astrophysics and Master of Trinity College at the University of Cambridge. He holds the honorary title of Astronomer Royal and also Visiting Professor at Imperial College London and at Leicester University. After studying at the University of Cambridge, he held post-doctoral positions in the UK and the USA, before becoming a professor at Sussex University. In 1973, he became a fellow of King's College and Plumian Professor of Astronomy and Experimental Philosophy at Cambridge (continuing in the latter post until 1991) and served for ten years as director of Cambridge's Institute of Astronomy. From 1992 to 2003 he was a Royal Society Research Professor. He is the author or co-author of more than 500 research papers, mainly on astrophysics and cosmology, as well as seven books (five for general readership), and numerous magazine and newspaper articles on scientific and general subjects. He has broadcast and lectured widely and held various visiting professorships, etc. His main current research interests are: (i) High energy astrophysics especially gamma ray bursts, galactic nuclei, black hole formation and radiative processes (including gravitational waves).

Contact A planetary nebula is ionized plasma clouds, produced from a hot central star of low to intermediate mass that is towards the end of its evolution. Its origin has been the subject of several investigations in recent years (see e.g. Soker, 1997 ). It is a key point to understand the late evolution of low- and intermediate-mass stars and the physical mechanism of mass loss for stellar evolution. ( Iben, 1995 ) Its properties of low-density dusty plasma may answer the remaining questions about the chemical composition of the interstellar medium and the chemical enrichment of our galaxy. ( Parker et al., 2006 There are two possible mechanisms for the formation of the planetary nebulae: single stars and binary central stars. The first mechanism involves a combination of magnetic fields and stellar rotation, which produces an axisymmetric mass-loss and expends stellar winds. ( Blackman, 2004

103. Astronomical Sketches Sketches of astronomical objects made at the telescope by Michael Geldorp. http://mordorp.zymichost.com/Astrohomepage/htmlfiles/index2.html

Welcome to the Astronomical Sketches web-site! Here you will find sketches of astronomical objects I made at the telescope. Shortly after starting observing with my telescope I found that simply recording in writing what I saw through the eyepiece wasn't adequate so I started making sketches of the objects I was observing. Sketches are a realistic way of recreating the images seen through a telescope and are comparatively easy to make. I have used nothing more than simple white paper and lead pencils of different hardness (soft, medium and hard) and an eraser. How I Made My Sketches I start a sketch of any given object by carefully studying it in the eyepiece for at least 10 - 30 minutes, taking in as much details as I can. Then I plot the background stars and the main features of the object, putting in lesser and fainter features as I progress. I write down descriptions of all relevant details as well. In this way, I end up with a rough version of the sketch as well as a written record of the object. The next day I complete the sketch, working from the draft and written record to produce the final version. To get the realistic white stars on black background feel, I then scan the image into the computer and make it into a negative. My early observations, dated 1998 - 2001 were all made from a small town in the Netherlands, called Alphen aan den Rijn, which suffers from quite a bit of light pollution. The vast majority of these were made with an 8" Dobsonian reflector with some made with a 4.5" Equatorial Newtonian. I have indicated the magnifications used on each sketch as well as filters, where applicable.

Highlights T hank you for visiting.. Astrocruise is about photography - photography of both our 'inner world' (the Earth) and our 'outer world' (everything beyond the Earth), namely the cosmos; the solar system, the milky way, galaxies, indeed the universe. Since the Earth is inextricably part of the cosmos there is a strong affinity; photography merges to astrophotography when we aim our cameras above the horizon. It is all photography, and essentially the same light illuminates all of these photographs; it is all a form of 'sunlight' - stars are distant suns. Astrophotography is a special form of photography that (uniquely) reveals objects that are invisible to the unaided eye - the distances within our macrocosm are so vast that much of it can only be seen by means of long exposure photographs. The camera, by accumulating light, helps reveal mysteries of the universe that otherwise remain invisible. The earth and all of its life forms evolved from the same elements that gave light to these photographs - it is all part of our natural heritage. The photography on these pages is largely from my home location in Wiltshire and from southern France. New images are added frequently so please visit again soon.
