. Mars is "behind" the sun from the earth's point of view and is therefore not visible in the nighttime sky (i.e. its up in the daytime). Venus it at greatest elongation and appears in the western sky as a bright object for 2-3 hours after sunset .

... Tidal influence on each of the galaxies in our sample is quantified by identifying and measuring the distance to the nearest companion, using a photometric technique with good completeness characteristics. ... Massnormalised starformation rates were derived using galaxy stellar masses estimated from zband luminosities Nearest companions were identified using the algorithm illustrated in Figure 1. ... Some of the lowredshift galaxies in our sample with close companions are illustrated in Figure 3. ...

... The 209 candidates were selected from our first and second priority samples introduced in Paper IV. Of 169 first priority candidates, 141 objects appeared in our list as new ones. 28 objects were listed in the NED as galaxies or objects from various catalogs with known redshifts and some of them already had information on emission lines in earlier publications. ... The ``random selected sample'' was created to access the fraction of BCGs in the second priority list and contains 43 objects. ...

The Earth. ... The middle raiding of the Earth is 6371,032 km, the pole 6356,777 km equatorial - 6378,160 km. The Earth surface area is 510,2 mln km^2, 70,8% of which is the World ocean. ... According to the modern cosmogonical views the Earth was formed 4,6 - 4,7 billions years ago from the protoplanet cloud captured by the Sun. ... The Earth is conditionally divided into 3 parts: a bark a cloak and a core (in the centre). The external layer - the bark is 35 km thick. ... Above the Earth. ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...
