Black holes . ... Black holes are objects for which the gravitational attraction is so strong that nothing, not even light, can escape from it. ... The material inside a black hole is concentrated into a singularity: a single point of infinitely high density where space and time are infinitely distorted. ... The existence of such black holes has been inferred in cases where the black hole pulls gas of a companion star that orbits around it. ... Gravity's Fatal Atraction: Black Holes in The Universe. ...

... Astronomers have used NASA's Hubble Space Telescope to probe the core of the nearest active galaxy to Earth, Centaurus A. Hubble's Near Infrared Camera and Multi-Object Spectrometer was used to peer past the dust to discover a tilted disk of hot gas at the galaxy's center (white bar running diagonally across image center). This 130 light-year diameter disk encircles a suspected black hole which may be one billion times the mass of our Sun. ... Centaurus A (NGC 5128) Fast Facts . ...

... They had expected to see impact craters like those on the other terrestrial bodies and from their number per unit area to estimate the age of Io's surface. ... This may have been the most important single discovery of the Voyager missions; it was the first real proof that the interiors of other "terrestrial" bodies are actually hot and active. ... A nalysis of the Voyager images led scienties to believe that the lava flows on Io's surface were composed mostly of various compounds of molten sulfur. ...

The seminar is supported by the grant of Federal Programm "Integration" . ... Measuring the Hubble Constant from Reverberating Accretion Discs in AGNs . We show how wavelength-dependent time delays between continuum flux variations of active galactic nuclei (AGNs) can be used to test the standard black hole--accretion disc paradigm, by measuring the temperature structure T(R) of the gaseous material surrounding the purported black hole. ...

Environments of Active Close Binaries I: ER Vulpeculae A.G. Gunn and J.G. Doyle A&A, in press High­resolution observations of the eclipsing active close binary system ER Vulpeculae have revealed excess emission in the Hff, the Ca II IRT and the Mg I b lines and excess absorption in the He I D 3 line. ... Analysis has revealed that the emission arises in plage­like material cov­ ering perhaps half of the secondary's surface. ...
