... 2008 December 11 . At the Center of the Milky Way . ... Explanation: At the center of our Milky Way Galaxy lies a supermassive black hole . Once a controversial claim, this conclusion is now solidly based on 16 years of observations that map the orbits of 28 stars very near the galactic center . ... Their ability to track stars so close to the galactic center accurately measures the black hole's mass and also determines the distance to the center to be 27,000 light-years. ... About APOD | ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... Since the Irkutsk IS radar is based on station "Dnepr", which was not intended for IS measurements, we made a serios effort to modernize this station in order to carry out ionospheric observations. Four main directions of the development of the radar experimental base: . modernization of the radar receiving system; . development of primary processing and measurement control methods; . ...

SINGULAR POINTS IN THE SOLAR CHROMOSPHERE . ... In the structure of the solar chromosphere, containing information on the configuration of the magnetic field, we have found and identified all the main types of the singular points ( see Fig. 1 ), which are known as inherent features of the 2-D vector field. ... The main types of the singular points are the node, the focus, the center, and the saddle. ... Singular point of the focus type in the solar chromosphere. ...

... CORCHAN(1) specifies the number of spectral channels per baseband channel (one polarization component) that the correlator will write. CORCHAN(2) specifies the number of channels to use in the internal FFT in the correlator. ... Over averaging can cause loss of amplitude due to ``delay smearing'' -- the effect of large phase slopes across the channels going into an average. ... But excessive numbers of channels lead to excessive output data rates and data set sizes. ...

The ESO Very Large Telescope consists of an array of four 8-meter telescopes which can work independently or in combined mode. ... In such a mount the telescope tube moves around a horizontal axis called elevation axis. ... The telescope tube itself consists of a steel structure supporting at the bottom the primary mirror (M1) in its cell, and at the top the M2 Unit by means of metallic beams called "spiders". ... The VLT can operate in either Cassegrain, Nasmyth or Coud focus. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...
