1. The Discovery of the Galilean Satellites
The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ... Galileo's Observations of Jupiter's Moons . ... Jupiter . ...

5. http://www.stsci.edu/documents/dhb/web/c10_fgsintro.fm7.html
... The two astrometry modes of the FGS are POSITION mode and TRANSFER mode. An FGS in POSITION mode acquires an object in FineLock and tracks it for an extended period of time. An FGS in TRANSFER mode acquires an object and scans the IFOV back and forth along a 45њ diagonal path in detector space to sample the interference pattern fully enough to construct an S-curve. POSITION mode observing with the FGS can determine the parallax, proper motion, and/or reflex motion of a given object. ...

EURONEAR - recovery, follow-up and discovery of NEAs and MBAs using large field 1-2 m telescopes . ... Using these data, we present the incidental survey work which includes 558 known MBAs and 628 unknown moving objects mostly consistent with MBAs from which 58 objects became official discoveries. ...

10. ON/OFF (Position Switching)
... The procedure simply observes ON your source for x minutes and then takes a `blank sky' observation OFF your source for the same amount of time and tracking the same azimuth and zenith angle range. ... Typically, observing times are kept to within 5 minutes (with 5 minutes as the most efficient, and therefore default, choice). ... If your scans are for 5 minutes or less, your wait time should be set to 1 minute (the default setting). ... A 5 minute ON/OFF + 10s CAL takes 11.3 minutes. ...

12. Laboratory of spectroscopy and photometry of extragalactic objects : Vortex1
... On the base of laboratory simulations (on rotating shallow water) of the formation of spiral arms in galactic gaseous disks, the existence of giant anticyclones in them was predicted. Numerical simulations shown that the vortex structures arise on a linear stage of spiral arms formation simultaneously with the latter. ... Thus second giants structures, after spiral arms, in spiral galactic disks are discovered. ...
