... October 17, 1999 . Black Holes in Galactic Centers . ... HST , NASA . Explanation: Do all galaxies have black holes at their centers? Although not even a single galaxy has yet been proven to have a central black hole , the list of candidates continues to increase. ... In all the galaxies studied, star speeds continue to increase closer the very center . This in itself indicates a center millions of times more massive than our Sun is needed to contain the stars. ... About APOD > . ...

... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

... As is known, the observed distribution of massive stars in the direction of the Galactic center looks very peculiar: the vast majority of all massive stars are concentrated towards the central 1 pc or so (Genzel et al. ... In order to compare the observed distribution of X-ray sources in the Galactic center with what would be expected from the population synthesis computations, we have considered two hypothetical scenarios for the location of the starburst. ...

The dark clouds, suggestively shaped like smoke rising from a pipe, are caused by absorption of background starlight by dust. ... NGC 1999: Reflection Nebula In Orion . ... Even as leap days go, today is a remarkable one. ...

... Low Polar Orbit . ... Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. ... Many spacecraft use such orbits, e.g. the US Air Force surveillance satellites of the DMSP series, or the series of French Earth-resources spacecraft SPOT . ... If the satellite then starts near a noon-midnight orbit, it will always pass near noon and near midnight. ...

Here user should specify the origin of coordinate system (observer's position). In case of rectangular coordinates it can be center of any major planet or the Sun or any minor planet. ... For spherical coordinates the origin of coordinate system can coincide only with the center of the Earth or with any point on the Earth surface. ... a)by code of observatory in the list of observatories maintained by Minor Planet Center (see IX. Observatories ). b)by introducing name of observatory. ...

ST-ECF Instrument Science Report WFC3-2005-07 Ground tests of the WFC3 NIR grisms S. S. Larsen, H. Bushouse, J. R. Walsh March 2005 ABSTRACT The fundamental parameters of a slitless dispersing element are the geometrical configuration of the spectral orders, the dispersion relation relating pixel offset to wavelength and the sensitivity of each order. Based on thermal vacuum tests, the performance of the WFC3 near-IR G102 and G141 grisms has been assessed. ... WFC3 IR Grism Modeling and Rotations. ...

This New Horizons LOng Range Reconnaissance Imager (LORRI) composite image shows the detection of PlutoтАЩs largest moon, Charon, cleanly separated from Pluto itself. Pluto is the brighter object near the center, and Charon is the fainter object near its 11 oтАЩclock position. The circles denote the predicted locations of the objects, showing that Charon is where the team expects it to be relative to Pluto. No other Pluto system objects are seen in these images. ...

... The experience of determination of the link between radio sources and dynamical reference frames is presented. To obtain this connection we used a series of very long baseline interferometry (VLBI) observations of the spacecraft Phobos-2 and angularly nearby quasars. ... The dynamical reference frame is determined by equator and equinox of these ephemerides. ... References . ... The relative orientation of the radio and dynamical reference frames can be described by a sequence of three rotations . ...
