XMM was initially planned to be a four-system X-ray observatory. However, a new design called the Optical Monitor was developed to provide simultaneous observation of X-ray telescopes in the UV and visible bands. As a result, the XMM mission was delisted.
Eventually, the XMM was replaced with Exosat, ESA"s X-ray observatory. Before its retirement, it had made 1780 X-ray observations.
During the project"s lifespan, XMM-Newton made several discoveries. These include the discovery of a new class of black holes, and the discovery of a galaxy cluster that is 1,000 times more massive than the Milky Way Galaxy. A new type of neutron star was also identified. Since then, XMM-Newton has studied more than half a million X-ray sources. Among these are the most dense neutron stars known to exist. In addition, the project has helped to characterize a group of missing baryons.
XMM-Newton"s mission was named in honour of Sir Isaac Newton, the world"s most illustrious scientist. Newton"s work laid the foundation for modern astronomy.
XMM-Newton has been studying quasars, super dense neutron stars, and black holes. It has also been studying the effects of absorption. Absorption reduces the accuracy of an observation. Using data collected from XMM-Newton, researchers have been able to quantify the effects of absorption and model them.
The XMM-Newton mission has led to the discovery of a new type of black hole. It has also been used to study super-dense neutron stars, a galaxy cluster, and star-shredding black holes. The mission is led by Principal Investigators who lead international teams.
An XMM file is a special type of file that can only be opened by specific software. Typically, it is a file that contains data, and it can be opened by right-clicking on the file and choosing "Open with." Other options include long-pressing and choosing "Open with" from the pop-up menu.
There are different kinds of XMM files, such as configuration files and system files. When an XMM file is opened, it can be displayed directly in a browser. If you have the necessary software, you can also convert the file to other formats. For instance, you can convert it to PDF, TXT, JPG, and PNG. You can open an XMM file in a Windows or Linux operating system, and you can also view the file using the browser.
XMM-Newton is a European Space Agency mission. The instruments it uses were designed by the European scientific institutes. XMM-Newton was launched in December 1999. It is composed of 3.9 tonnes and will be launched by an Ariane 5 rocket. The mission will study quasars and other astronomical objects, and will be operated by the European Space Agency.
