... the time of observation . ... Observing the Changing Position of the Sun To Establish Cardinal Directions . ... Observations of the Sun's apparent movement across the sky and its pattern of rising and setting in the east and west horizon helped to establish the cardinal directions. ... The final stage of the Sun's return was marked by the observation that the Sun had reached its highest altitude when the full width of your mitted hand could fill the gap between the Sun and the horizon. ...

We describe multi-wavelength, simultaneous observations of the RS CVn star, II Pegasi, most of which were obtained during the first three weeks of September 1992. These observations were made using optical and infra-red broad-band photometry, ultraviolet and optical spectroscopy and microwave monitoring. ... One of the flares, observed in optical photometry and ultraviolet spectroscopy is one of the most energetic ever observed on this star. ...

... The TESIS is a set of solar imaging instruments developed by the Lebedev Physical Institute of the Russian Academy of Science, and launched aboard the Russian spacecraft CORONAS-PHOTON on January 30, 2009. The main goal of the TESIS is to provide complex observations of solar active phenomena from the transition region to the inner and outer solar corona with high spatial, spectral and temporal resolution in the EUV and Soft X-ray spectral bands. ... Solar activity hits a new low . ...

... 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 . ...

This artistтАЩs impression shows exoplanet HD 189733b as it passes in front of its parent star, called HD 189733A. HubbleтАЩs instruments observed the system in 2010 and in 2011 following a large flare from the star (depicted in the image). Following the flare, Hubble observed the planetтАЩs atmosphere evaporating at a rate of over 1,000 tons per second. ...
