This spectacular image of part of a winding channel called Nanedi Valles was taken by the Mars Global Surveyor spacecraft in 1998. The channel is about 2.5 km across, and shows a variety of geologic features that strongly suggest it was carved by running water. (Courtesy of Malin Space Science Systems/JPL/NASA.) .

... Obs., 1974, v.49, p.80-85. The sixty five radial velocity measurements of Cep C (blue visual companion of Cep A) have been obtained. The evidences are give that Cep C is spectral binary. The most probable periods of system are: 0 d ,89986 and 0 d ,46458 . In both cases the -velocity of Cep C is in good agreement with mean velocity of Cep A. It is a strong argument on their physical connection. The secondary component of Cep C may have very low mass (near 0.1 solar mass or less). ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
