62. White Dwarfs And Novae Short on text, but contains excellent images, diagrams and a table of the brightest white dwarfs http://csep10.phys.utk.edu/astr162/lect/novae/novae.html

White Dwarfs and Novae (Section Not Complete) Subrahmanyan Chandrasekhar predicted while a very young man in the 1930s that there was a limiting mass for white dwarf stars: no white dwarf could be stable against gravitational collapse if it exceeded this mass, which is about 1.4-1.5 solar masses, depending on the detailed composition of the white dwarf. The idea was not very well received by many established astronomers, who considered it absurd that a white dwarf could have a limiting mass. Much later, Chandrasekhar's brilliant idea was completely accepted within the astrophysics community and he eventually won a Nobel Prize for his deep theoretical contributions to astrophysics. Today, all textbooks on stars describe the Chandrasekhar Limiting Mass for white dwarfs as central to the structure of white dwarfs (Ref) Cooling of White Dwarfs The adjacent image shows a white dwarf embedded in a planetary nebula that may be the hottest star kn own. Its surface appears to have a temperature of about 200,000 degrees C, which is 30 times the surface temperature of the Sun (Ref) . Even though the temperature is so high, this is a dying star. It has used all its nuclear fuel and can no longer produce energy by thermonuclear fusion.

They heat up the interstellar medium, distribute heavy elements throughout the Galaxy, and accelerate cosmic rays . But just what is a supernova? And is there more than one type? Indeed, there seems to be two distinct types of supernovae those which occur for a single massive star and those which occur because of mass transfer onto a white dwarf in a binary system. As you will see, however, it is only what gets the process started toward the explosion which differs between the two types. Supernovae from Single, Massive Stars

68. Dark Sky Czech Republic Gives information, letters and press releases about the Czech light pollution law, parts of the law, images of various lighting fixtures, lightpollution software and contact details for members. http://www.astro.cz/darksky/

Night Environment Pollution and the Remedies through Legislation and Technology, in Czechia and in general The main principle is simple, don't use artificial lighting outdoors when and where it's not necessary let the light go just the right direction: down (and steep enough). Lighting fixtures with no curved belly (a flat glass instead) do the job, (if lighting is really needed) like these in central Europe: eco-settlement in Kassel Strasse der Solarenergie in Gleisdorf in front of Brno railway station parking lot in front of the museum in Gleisdorf Most information is in Czech only (see http://svetlo.astro.cz , or, as a novelty, a huge research report within http://amper.ped.muni.cz/noc ), just a couple of things is in English as well (a non-local one is on lighting and crime Czech Republic included light pollution in its newly coined Clean Air Act in 2002, a step much appreciated throughout the world. However, the Act contained a declaration only, the government had to issue the very rules. It had never happened, due to efforts of ... and unconcern of ... (you can guess, I have to be diplomatic). However, our effort to formulate simple and still effective set of such rules led to a draft submitted to the House of Representatives (it has not been accepted, as e.g. there was no support from the Ministry of Environment, unlike in 2001), which may be of interest to everybody. I'd appreciate any advice what should be changed in this set to fit legislation of most countries. I have to stress that the

70. IfA -- Comet Hale-Bopp Includes news and images obtained by University of Hawaii astronomers. http://www.ifa.hawaii.edu/images/hale-bopp/hale-bopp.html

Comet Hale-Bopp at the UH Institute for Astronomy C omet Hale-Bopp is now moving away from the inner Solar System. As it receives less energy from the Sun, the cometary activity is slowing down, the tail is disappearing and the comet will rapidly become too faint to be observed with small telescope. While this marks the end of Hale-Bopp's public performance, it is not the end of the story: we plan to continue observing it as long as possible. The decrease and cessation of a comet's activity give very interesting information on its composition and history, so we are trying to observe comets as far as possible from the Sun. A typical comet nucleus has a diameter of 1 to 10 km, and is extremely dark, so that task is far from easy and requires big telescopes and very long exposures; in the case of Comet Hale-Bopp, we hope a to have an easier task, as we know that the nucleus is very bright. For more information, check out Karen Meech's Distant Comet Reseach page , and for an example of tricky observation, have a look at the faintest Solar System object ever observed: Comet Halley at the distance of Uranus , which is also the last image of that comet.

Welcome to the Multiwavelength Astronomy Gallery! For selected astronomical objects in the famous Messier catalog , as well as for some non-Messier objects, we have gathered images taken at different wavelengths by a variety of ground-based and space-borne observatories . The primary purpose of this gallery to introduce the wealth of data available at wavelengths beyond the familiar visible light we are accustomed to seeing. You will discover some important characteristics of astronomical phenomena, and learn about which types of radiation are best suited for studying certain objects. You can learn more about a particular object by clicking on the banner at the top of each object's Gallery page. This will provide you with general background information about that particular object, courtesy of the Students for the Exploration and Development of Space . At the top of each Gallery is a mosaic of various images, each taken at a different wavelength. By scrolling down through the Gallery, you will find copies of each image, accompanied by explanatory text which will explain the similarities and differences between images.
