Abstract Many observers in the past gave detailed descriptions of the telescopic aspect of Venus during its extremely rare transits across the Solar disk. In particular, at the ingress and egress, the portion of the planet’s disk outside the Solar photosphere has been repeatedly perceived as outlined by a thin, bright arc (“aureole”). Those historical visual observations allowed inferring the existence of Venus’ atmosphere, the bright arc being correctly ascribed to the refraction of light by… Expand
The June 2012 transit of Venus - Framework for interpretation of observations
Ground based observers have on 5/6th June 2012 the last opportunity of the century to watch the passage of Venus across the solar disk from Earth. Venus transits have traditionally provided uniqueExpand
Glancing views of the Earth. From a lunar eclipse to an exoplanetary transit
It has been posited that lunar eclipse observations may help predict the in-transit signature of Earth-like extrasolar planets. However, a comparative analysis of the two phenomena addressing inExpand
Glory revealed in disk-integrated photometry of Venus
Context. Reflected light from a spatially unresolved planet yields unique insight into the overall optical properties of the planet cover. Glories are optical phenomena caused by light that isExpand
Multilayer modeling of the aureole photometry during the Venus transit: comparison between SDO/HMI and VEx/SOIR data
The mesosphere of Venus is a critical range of altitudes in which complex temperature variability has been extensively studied by the space mission Venus Express (Vex) during its eight-years missionExpand
Observation of Venus and Mercury Transits from the Pic-du-Midi Observatory
The Pic-du-Midi, on the French side of the Pyrénées, became a state observatory in the summer of 1882. The first major astronomical event to be observed was the Venus transit of 6 December 1882.Expand
Venus Atmospheric Thermal Structure and Radiative Balance
From the discovery that Venus has an atmosphere during the 1761 transit by M. Lomonosov to the current exploration of the planet by the Akatsuki orbiter, we continue to learn about the planet’sExpand
The vertical density profile of the mesosphere of Venus by independent measurements from SPICAV/SOIR and aureole photometry
The mesosphere of Venus, above the optically thick cloud deck, remains poorly known and shows an important variability as a function of position and time as revealed by Venus Express (VEx) dataExpand
Solar diameter with 2012 Venus transit
The role of Venus and Mercury transits is crucial to know the past history of the solar diameter. Through the W parameter, the logarithmic derivative of the radius with respect to the luminosity, theExpand
Using the transit of Venus to probe the upper planetary atmosphere
This work measures the altitude of the densest ion layers of Venus's ionosphere (CO2 and CO), useful for planning missions in situ, and a benchmark case for detecting transits of exoplanets in high-energy bands with future missions, such as the ESA Athena. Expand
Venus transit, aureole and solar diameter
Abstract The possibility to measure the solar diameter using the transits of Mercury has been exploited to investigate the past three centuries of its evolution and to calibrate these measurementsExpand


This paper presents the only space-borne optical-imaging observations of the 2004 June 8 transit of Venus, the first such transit visible from Earth since AD 1882. The high-resolution, high-cadenceExpand

The atmosphere of Venus was discovered for the first time by the Russian scientist Mikhail V. Lomonosov at the St Petersburg Observatory in 1761. Lomonosov detected the refraction of solar rays whileExpand
Water vapor variations in the Venus mesosphere from microwave spectra
Abstract Mm-wave spectra of HDO in the Venus mesosphere (65–100 km) were obtained over the period March 1998 to June 2004. Each spectrum is a measurement of the hemispheric-average H 2 O vapor mixingExpand
