... The very demanding goal of 50 milliarcseconds root-mean-square (mas RMS) for the astrometric precision of the Sloan Digital Sky Survey implies that focus and collimation motions of the secondary must be very smooth. The Apache Point Observatory 3.5-m telescope secondary is a hot-gas-fusion borosilicate lightweight (25% of solid) mirror. ... Differential rotation provides tilt motions. ... Also, we made measurements with the indicators sensing the motion of the whiffletrees near actuators 1 and 2. ...

... Team makes first direct measurement of distant galaxy's magnetic field . ... Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago. ... Until recently, astronomers knew very little about magnetic fields outside our own galaxy, having directly measured the magnetic field in only one nearby galaxy. ... Magnetic fields stronger than expected . ...

The radiation belts around the planets are the interrnal regions of planets' magnetospheres where the own magnetic field of a planet keeps the charged particles (protons and electrons) having the great kinetic energy. ... They usually distinguish the Earth's internal and external radiation belts. the internal radiation belt of the Earth has the maximum particles density (mainly protones) over the equator in the height of 22 thousand km. ... Jupiter and Saturn have the powerful radiation belts. ...
