Sometimes it takes little to keep this physicist happy on an airplane. A window seat, where the plane’s shadow is visible or has disappeared into the distance, provides the opportunity to observe a variety of phenomena associated with sunlight that

Investigations on the dynamical structure of Venus upper atmosphere were carried out by infrared heterodyne Doppler wind measurements shortly before and after the venusian inferior conjunction on March 27, 2009. The Cologne Tuneable Heterodyne Infrar

The Gegenschein is viewed by the Solar Mass Ejection Imager (SMEI), which has provided near-full-sky broadband visible-light photometric maps for over 5 years. These have an angular resolution of about 0.5° and differential photometric stability of

We have used near-infrared spectroscopic observations of the Venus nightside taken with the Infrared Imager and Spectrograph 2 (IRIS2) on the Anglo–Australian Telescope to derive temperature maps for the Venus mesosphere at an altitude of ∼95 km.

This paper is devoted to the analysis of the results of wide-angle polarimetric observations of the night sky, which has been carried out in December 2002 in the Southern Laboratory of Shternberg State Astronomical Institute (Crimea, Ukraine) in a co

The dynamical regime of the Venus upper atmosphere is mainly decomposed into three regions. The first one, located below 65 km of altitude is governed by the retrograde superrotational zonal (RSZ) circulation. The second region above 130 km is domina

A cooled CCD camera with 385 x 576 pixel has been used, in conjunction with a 16-mm fish-eye lens, to construct an isophot map of the zodiacal light and the gegenschein. The axis of symmetry of the zodiacal light at westerly elongations has been meas

We made optical observations of the Gegenschein using a liquid-nitrogen-cooled wide-field camera, Wide-field Imager of Zodiacal light with ARray Detector (WIZARD), between March 2003 and November 2006. We found a narrow brightness enhancement superim

Nitric oxide δ (190–240 nm) and γ (255–270 nm) bands have been observed on the Venus nightside with Venus Express SPICAV instrument operated in the nadir mode. These ultraviolet emissions arise from the de-excitation of NO molecules created by
