... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... As we have seen, evolutionary considerations based on our current understanding of massive binary systems lead to the conclusion that BH+PSR binaries must constitute a rather numerous subclass of all binary PSR ( 1 per 1000 isolated pulsars; Lipunov et al. , 1994b[ 124 ]). It seemed a priori that the binary radio pulsar PSR B0042-73   in the SMC (Kaspi et al., 1994[ 81 ]) could belong to one of these two classes. ... This means that such binary pulsars should be discovered in the near future. ...

... 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 England observer Lew Gramer, fresh back from his mid-November fish observing and meteor-catching expedition in South Florida, reports that December also promises to be a great month for celestial sky-sparks!" ... Other showers adding to the mix this month include several very minor showers, such as the Chi Orionids (3 Dec), Monocerotids (9 Dec) and Sigma Hydrids (12 Dec), which usually contribute no more than 2 or 3 meteors per hour during even post-midnight observing this month. ...
