Planetary Nebula NGC 2440 . ... Acknowledgment: Hubble Heritage Team ( STScI / AURA ) Explanation: Planetary nebula NGC 2440 has an intriguing bow-tie shape in this stunning view from space. The nebula is composed of material cast off by a dying sun-like star as it enters its white dwarf phase of evolution. Details of remarkably complex structures are revealed within NGC 2440, including dense ridges of material swept back from the nebula's central star. ... NASA Official: Jay Norris. ...

... Developments and characterization of novel oxide materials with high ionic, electronic or mixed conductivity, superior electrochemical and catalytic activity, advanced thermomechanical properties, and enhanced stability in a wide range of operation conditions, and, thus, collection and systematization of new fundamental information important for technological applications of the novel materials; . ...

... Science . ... Science Users Information > Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: Why most supermassive black holes do not accrete material . ... Implicitly, we will also better understand why most supermassive black holes fail in accreting material. ... 1) Analyse multi-wavelength data for selected galaxies to describe and quantify the different physical phenomena in their centres, and most notably to derive their central supermassive black hole masses....

... We want to know time-scales, and sequences of events, and the ages of stars. ... We would, ideally, like to create a solar comparison sample by finding stars of essentially the same mass, composition, and age and then observing the range of behavior they exhibit. ... At best we can estimate a star 's age. ... Having to construct models that work consistently across a broad range of masses constrains the problem, and yet even for the nearest open clusters we do not know the age to even 10%. ...

National Aeronautics and Space Administration . ... Bruce McCandless II (Captain, USN, Ret.) NASA Astronaut (former) . ... He was a member of the astronaut support crew for the Apollo 14 mission and was backup pilot for the first manned Skylab mission (SL-1/SL-2). ... A veteran of two space flights, McCandless has logged over 312 hours in space, including 4 hours of MMU flight time. ... With the completion of this flight McCandless logged 191 hours in space (including 4 hours of MMU flight time). ...

... A subset of the Observatory's research activity, namely the list of 41 refereed journal publications during 2004 and one book, is given in Appendix C . ... The remainder of this section first summarises a few highlights of the Observatory's research and other activities during 2004, and then, under the headings of the Observatory's senior research staff, presents lay reports of some of the principal research and related activities undertaken by these staff and their colleagues during 2004. ...

The database contains references to the papers, data files and links to the Internet resources related to measurements and calculations of the optical constants in the wavelength interval from X-rays to radio domain. ... References to some useful books and reviews on the subject (e.g. the classical handbooks edited by E.D.Palik) and links to Internet collections of optical constants and personal WWW pages with related software were also placed in the database. You have arrived at our welcome page. ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... The material in "From Stargazers to Starships" meets several important requirements of the national standards. Pages cited below are from National Science Education Standards National Academy Press, Washington 1995. ... For example: the sections on astronomy not only describe calendars and sundials (including their construction), but also the astronomy of the ancient Greeks, including two different ways in which ancient Greeks estimated the distance to the Moon. ...
