Ticho Brague (1546 - 1601). Ticho Brague was the greatest astronomer-observer, an outstanding scientist and a designer of astronomic tools. He founded the first European astronomic centre, where the great amount of the work was carried out during 20 years. ... The astronomical observations of Ticho Brague seemed a pastime for his contemporaries, appeared to be a basis of the modern law of gravitation. ...

... 16-mm/2.8 Fish-eye . ... I set up my Edixa Prismaflex TTL on a tripod outside the dome at Zeiss 50" and opened the camera for several hours. The 2.6 m Shain reflector is visible at center. The time exposure of about 5 hours duration showing circumpolar stars. The dome can be seen to blur slightly due to their motion during the exposure. Back to Astronomical Images Home Page . ...

... Heracles Triplane and Aerospace Systems . The key characteristics of two-stage aerospace systems are determined according to speed and carrying capacity of the aircraft-carrier used . ... So the SPIRAL system hypersonic carrier was expected to launch the second stage by weight 63 tons at a speed corresponding to 6M; whereas launching weight of the MAKS system orbital stage with the use of the An-225 MRIYA heavy subsonic aircraft reaches 275 tons, and the HERACLES aircraft - 450 tons. ...

... We have imaged with milliarcsecond resolution at 5 GHz 374 strong flat-spectrum radio sources north of declination -44 using the VLBA in June 1996. ... The data were processed with the NRAO AIPS software package and the Caltech Difmap package. ... The VLBApls source sample . ... Click on the J2000 IAU name (in the left column) or the alternative name (mostly B1950 IAU names, in the right column) to get more information on a source, including coordinates, redshift, VLBApls images and model components...

The Database of Close Binary Systems . ... Team . ... This web-based interactive database is being developed and maintained by a team at the Sternberg Astronomical Institute of the Moscow State University . The project is an on-line extension of our catalogue on "Highly Evolved Close Binary Stars" (volumes I, II) published by Gordon and Breach in 1996. As of September 2009, the database (both the software and the content) is in its development/testing phase. ...
