It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms.

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

New Satellites of Saturn . On July 26, 1995, Amanda Bosh of Lowell Observatory announced the discovery of at least two and perhaps four new satellites of Saturn .

The trapping of particles by magnetic fields was first studied by Kristian Birkeland in Norway, starting around 1895. ... Poincare managed to solve the motion of charged particles near an isolated magnetic pole, showing that they spiraled around field lines and that they were repelled from regions of strong field. ... A more realistic problem, of more interest to Birkeland, was particle motion near a compact bar magnet or "dipole", which better approximated the field of the Earth or of his terrella. ...
