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. ...

A visual impression of the data used in the study. The relevant extra-galactic maps are represented as shells of increasing distance from Earth from left to right. ... After this are six shells containing maps of the millions of distant galaxies used in the study. These maps are produced using different telescopes in different wavelengths and are color-coded to show denser clumps of galaxies as red and less dense regions as blue. There are holes in the maps due to data quality cuts. ...

Peremennye Zvezdy ( Variable Stars ) 26 , No. ... Our BVR CCD photometric study of the globular cluster NGC 7006 permitted us to find two new suspected RR Lyrae variables. A cluster chart is presented with the position of known and suspected variables marked. ... According to the Catalogue of Variable Stars in Globular Clusters (Clement et al., 2001), it contains 76 variables, most of which are RR Lyrae variables, the RR1 to RR0 ratio being 8:55. ... for suspected and some of known variable stars. ...

... This review presents the results of Scenario Machine computations aimed at the population synthesis of different types of binary stars in our Galaxy and another galaxies. They demonstrate the ability of this method to make an important gross analysis of the modern scenarios for binary evolution, as well as to give interesting qualitative and quantitative predictions which can be checked observationally. ... The future development of the method can be considered from two different points of view. ...

The first series of images refers to NGC 1672, a barred spiral. We present a gray scale V-band image to show the overall morphology, followed by an intensity map in H-alpha which shows how the H II regions are distributed, followed by the velocity map. ... Different colors refer to different velocities as the galaxy is rotating. ... The following image is an H-alpha intensity map of the spiral galaxy NGC 1292. ... This next image is an H-alpha intensity map of the spiral galaxy NGC 1406. ...

... Colours of stars and galaxies hold information on intrinsic and extrinsic parameters, such as stellar temperatures and galaxy populations, selective absorption and colour changes due different dust contents and inclination angles of galaxies, as well as galaxy redshifts and evolution. ... The colour magnitude diagram of 65000 galaxies to which all above-mentioned quantities and others contribute can only be explained by comparison with simulations. ... Colours are also of technical help. ...
