... The reduction system of observations FADPS (description in Russian) (Flexible Astronomical Data Processing System) for data of wide-band receivers of the first observation cabin of the radio telescope RATAN-600 had been created under the Unix-like operational system DEMOS for computers of the SM-1420-type (PDP/11) in 1987 for observation analysis and estimates of coordinates and flux densities of radio sources. ...

... Our Galaxy . ... Universe . ... One of the Hubble Space TelescopeтАЩs goals was to accurately observe Cepheids in the most distant galaxies known (we knew they were far away, the problem was saying just how far). ... This work is becoming ever more refined; in January this year astronomers revealed that they had identified the farthest galaxy yet seen in a Hubble image. ... Thanks to the Hubble Space TelescopeтАЩs superb observations we can say that the universe is 13.75 billion years old. ...

In other words, by far most meteorites falling on Earth are chondrites. Finds are meteorites that were not seen to fall but were subsequently discovered on the ground, often long after they landed. ... The vast majority of meteorites in museum and private collections around the world are finds, not falls. ...
