... 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. ...

... The antenna system . ... A military radar system, consisting of two identical radars, was transferred to the Institute of Solar-Terrestrial Physics (ISTP). ... The system features a two-channel transmit-receive antenna. ... By changing the phase difference in the channels, one is able to modify the shape of the total channels' beam in the angle-of-elevation plane. ... The total beam is controlled by introducing the phase signal into the excitation signal of one of the channels. ... Peak power.. ...

AUTOMATIC CREATION OF THE HYPSOMETRIC MAP OF VENUS. ... The hypsometric map of Venus (1:45M) created under editing of Dr. Rodionova gives the representation of the planet relief on the basis of up-to-date data. ... The requirement was to preserve contour polygons with the areas more than 10 000 sq. km at the Venus surface, which corresponded with areas approximately more than 5 sq. km at the map. ... The other side of Venus map has been prepared. ... Surface height histograms for both Venus and Earth. ...

In addition to the monitor configuration, ACES also has a helmet-mounted display system that creates a digital view of reality. ... Recently, in the high deserts of Arizona, ACES' versatility proved useful in supporting the ongoing testing of NASA's prototype planetary rover, also known as the Science Crew Operations and Utility Testbed (SCOUT). ... NASA/John Frassanito and Associates The launch system that will get the crew off the ground builds on powerful, reliable shuttle propulsion elements. ...

STARTEST IMAGES GALLERY . STARTESTING TELESCOPES WITH AN AUTOCOLLIMATOR . ... This website is a joint effort of Markus Ludes from APM-Telescopes and Cor Berrevoets ( Aberrator free startesting Software ). The site aims at explaining the different aspects of star-testing telescopes. ... Markus Ludes (APM telescopes) used a high quality 10" Maksutov Newtonian (Zygo tested at 632,8 nm with the following errors: 1/10.1 wavefront p.t.v. and 1/51 wavefront RMS) as collimator in single pass scheme. ...

UPPER PANEL: The gas surface density map in log scale. The red circle in the center represents the central protostar. The development of spiral structure in the protostellar disk is evident. Dense protostellar/protoplanetary clumsp form within the spiral arms and are driven into the protostar by the action of gravitational torques. LOWER PANEL: The mass accretion rate onto the protostar as a function of time. The mass accretion rate is characterized by very short ( . ...
