From a computing standpoint, flash X-ray radiography is much more time-consuming than traditional X-ray applications, and despite the constant increase of computing resources, methods to reduce the calculation time while preserving accuracy are highl

On the basis of systematic observations of sunspots available since Galilei’s time, we have been able to derive certain properties of normal and low-activity cycles, such as those of the Maunder minimum cycles. The characteristics used are the suns

Historical records suggest that during the seventeenth century the Sun was subject to an anomalous scarcity of sunspots (the Maunder minimum1). This minimum was coincident with a severe temperature dip of the Little Ice Age2, from which a relation be

The subject of extraterrestrial civilizations is relevant to astronomy in two ways. Firstly, the very existence of life outside Earth is dependent upon the picture that astronomers can draw of the Universe, and we will see how that picture allows us

The Paris observatory is in possession of a 53 y record of solar diameters and sunspot positions during the Maunder minimum (1666 – 1719). For the period (1666 to 1684), the solar diameter was 32′9″ and slowly decreased down to 32′6″ when s

The equipment used by professional astronomers in past centuries was no better than that used by modern amateurs. Systematic observation of the Sun began in the 17th century and continuity of observations is very important for understanding the solar

Recently reported measurements of the circular polarization of the radiation from extragalactic radio sources have indicated that the polarization may be variable1 and that the polarization is greatest for sources with flat or inverted spectra2,3. To

Circular polarization measurements were made with the Parkes 64 m telescope on 66 mainly extragalactic sources, 33 of which were studied at two or more frequencies. Circular polarization was definitely found in the eight quasi-stellar sources PKS0237
