Nearly four centuries ago, Galileo's simple observations of Earth's planetary sibling, Venus, buoyed the proponents of a Copernican universe. ... The Italian astronomer had settled into a new house in Florence and had begun to observe Venus, which in November 1610 would have appeared as an evening star, bright in the western sky after dusk. ... From these two observations, Galileo inferred that Venus must orbit closer to the Sun than does Earth. ...

... 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 . ...

... Astronomy news . ... NASA's Spitzer Images Out-of-This-World Galaxy . ... It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white. ... The ring around the black hole is bursting with new star formation. ...

... The combined event list takes from the intermediate event lists all of the events (combined into a single table), the collections of CCD-specific exposure tables and Good Time Interval (GTI) tables, and the collections of node-specific bad pixel tables and rejectable pixel tables. Name collisions among tables copied in from the intermediate event lists are avoided by placing the corresponding CCD number at the eighth character of the extension name. ... table : EVENTS -- evlistcomb . ... int32 . ...

RTT150 . ... This search system is designed for generating the necessary information on series of pointings (observations of each source consist of sets of exposures with different filters and sometimes with different exposure times) for observed sources. Search results appear at the separate page as a table with the following data: . DATE - real (not evening!) observations date (in YYYY-MM-DD format); . ... Bin - minimal CCD binning mode (may vary during the observations); . ...

Space Radio Telescope . The space radio telescope antenna consists of a deployable parabolic reflector (10-m diameter) which is made of 27 carbon fiber petals and central solid portion (3 m in diameter). The radio telescope has focus to diameter ratio F/D=0.43 and overall RMS surface accuracy 0.7 mm. ... A concentric feed arrangement at prime focus will provide the possibility of observing at two frequencies or two circular polarizations simultaneously. ... Observing frequency (MHz) . ...

There are presently rows in this table, i.e. an average of tables per catalog. ...

... However, focal plane curvature is such that an attempt must be made to approximately place the ends of the optical fibers feeding the spectrographs on the best focal surface rather than simply a plane. ... We deform the plate during drilling so that all the holes can be drilled with their axes parallel. ... The mandrel is the shape that the plate should have for drilling if all holes are drilled with their axes parallel and if the plate is deformed to match the best focal surface in the telescope. ...

... 2 April 1999 . The Nobeyama Radioheliograph data show that in the microwave range, besides large-scale trans-equatorial chains (see, e.g., the May 11-15, 1993 and November 1-4, 1993 events), there are also many examples displaying large and strongly evolving "longitudinal" or "internal" chains connecting remote active regions inside an active zone in one (northern or southern) hemisphere (the August 20-September 3, 1998 event). ...
