Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

... Precisely one month ago, on 11 July 2009, the last active area of the new solar cycle disappeared from the surface of the Sun. Over the 30 days following this, neither observers on Earth nor devices in space have been able to detect the emergence of any sunspots. ... Therefore, it seems that our star has once again returned to a state of deep solar "winter", following several sparks of activity in May-June 2009. ... To date, this period has lasted 30 days. ...

Brad Carter, Carolyn Brown, Rhodes Hart Drew Foster, John Kielkopf, Ron Moore University of Southern Queensland, Australia University of Louisville, Kentucky, USA OVERVIEW Mt Kent Observatory is now providing live remote observations of southern skies as part of a collaborative project between USQ, the University of Louisville, and Northern Kentucky University. ... This enables observers to make daytime use of a remote telescope during its local night-time, and image otherwise inaccessible skies. ...

... Сегодня: 10 апреля 2016 г. Космический корабль, который работает на солнечной энергии, вскоре может начать свой полет по Солнечной системе. Группа американских и российских ученых готовится запустить зонд с гигантскими пластиковыми "парусами", которые могут ловить солнечный свет подобно тому, как паруса яхт ловят ветер, пишет The Observer (перевод на сайте Inopressa.ru). ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
