This is a color composite image made by Karen Gloria at Hopkins Observatory using a 6-inch refractor and a 512x512 element CCD detector. This is the famous Trifid Nebula, often photographed. It is a nice illustration of the combined effections of ionization and scattering caused by the large yield of blue and UV photons from newly formed massive stars.

... The Magnetic Sun . ... Galileo had guessed they were clouds floating in the Sun's atmosphere, obscuring some of its light. ... It turned out that the Sun has a polar field somewhat like the Earth's, but that it reverses its polarity during each 11-year cycle. ... Sunspot fields were evidently produced by electric currents, and it was well known that such currents could be generated by a " dynamo process ," by the motion of an electric conductor (e.g. the flow of solar plasma) through a magnetic...

... I studied a variable star with small light variations found on the Kepler satellite. ... I calculated the surface properties and created a hypothesis of a reflecting binary star system to be the cause of this variation in luminosity. ... I can do this by studying the atomic spectra of the star. ... I found the star to be rich in Helium. I then compared the spectrum against model spectra of Helium rich stars to work out the surface gravity, surface temperature and Helium abundance of the star. ...

Telescope Jumps: One Cause is Found . ... One tries to take out the sag of the secondary cage as the telescope is pointed toward the zenith. The second component tries to take out changes in the secondary piston caused by temperature changes of the truss structure. ... Second, the jumps only occur when the temperature data causes motions of the piston which go in a direction opposite to the direction in which the sag component is driving the secondary. ... One has to wonder how this can occur. ...

... Bad Astronomy . ... What Color is Mars? ... He then labels the image on the left "NASA (Odyssey -- colorized)" and the one on the right "ESA (Mars Express -- HRSC Color)". ... In other words, he is implying the ESA Mars Express image is correctly colored, and the Odyssey image is not. ... So ironically, the three-color image is not "true color", because the color balance is off, and the single color image which was colorized by an artist more closely resembles the real colors of Mars. ...

OptInt PmWiki : Pm Wiki / Wiki Style Examples . Wiki styles | ... PmWiki uses WikiStyles for styling text with color and other attributes. PmWiki 2.0 introduced the ability to control the styling further and to even place styles on blocks. ... In addition, an author can define a style "shortcut" by using the define= property. For example, to define a style of %red% , one can use: . define=mystyle color=red% Here is some %mystyle% red text created using a style shortcut. ...

... These colors are not only beautiful, they give us clues to the stars’ sizes, ages and life cycle status. ... While stellar life is interesting, stellar death results in many of the objects that amateur astronomers love to observe including planetary nebulae, supernova remnants and black holes. ... Dr. Russell Pinizzotto is currently the Dean of the Faculty of Science and Engineering at Merrimack College in North Andover, MA. ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

... The color selection widget is, not surprisingly, a widget for interactive selection of colors. ...

... During the analysis of the surveys carried out on RATAN-600, it was found that almost one fifth of the detected sources shows significant radio flux variations. ... We used the data from "Cold" radio surveys carried out with RATAN-600 in 1980-1994 to search for radio sources with significant flux variability. ... On possibility of detection of variable sources using the data of Cold surveys carried out on RATAN-600. ... Detection of Variable Sources Using the Data of "Cold" Surveys. ...

... Pre-university education . ... The scientists of the Department of Physical Chemistry and Chromatography of Samara University (joint SSAU and SSU) have developed a way to mark the oil covertly. ... Moreover, unlike various dyes which are sometimes used for oil marking, the development of Samara University chemists is visually undetectable. ... The next work stage of the Samara University chemistry scientists will be the development of hidden markers for petrochemical products - gasoline and oil. ...

The results of a search for ultrarapid variability of galactic water maser sources at the wavelength 1.35 cm on a timescale of several minutes to 1 h are reported. A special observational technique was developed. ... Among those, several sources that have shown such variability were found. ... Clear evidence for such a variability type was found in at least two sources: W49N and W33B. Variability of this kind displays itself only in certain states of the water masers. ...

THE ARGUMENT AGAINST LONG EXTRAGALACTIC DISTANCE SCALE Gaseous discs of S0 -- Sd galaxies appears to be gravitationally stable or close to stability. Dependence of the gravitational stability parameter of gaseous disc $M_g/M_c$ upon the color index $(B-V)^0_T$ which reflects a relative number of young stars, is found. Here $M_g$ is total mass of gas in a galaxy, $M_c$ - mass of gas which corresponds to marginal stability of gaseous disc at distances from center. ...

With the aim of providing steady development of astronomy and spreading astronomical knowledge the Euro-Asian Astronomical Society (EAAS) and the Euro-Asian Association of Astronomy Teachers (EAATA) of the EAAS with the assistance of the P.K.Sternberg State Astronomical Institute (in Moscow), Special Astrophysical Observatory of Russian Academy of Sciences (in Niznij Arkhyz) and the Moscow-Regional ...

... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...
