... 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. ...

... The survey uses HARP, a new submillimetre heterodyne array at the James Clerk Maxwell Telescope (JCMT), to map the J = 3 - 2 rotational transitions of CO and its isotopologues 13CO and C18O across 630 sq. arcmin of the Perseus molecular cloud, in four regions: NGC1333, IC348, L1448 and L1455. ... A new catalogue of 850 micron SCUBA clumps is identified using two automated algorithms, clfind and GaussClumps. ... These data are one of the largest surveys of molecular outflows ever undertaken. ...

Next: Binary Radiopulsars with Black Up: Black Holes in Binaries Previous: Black Holes in Binaries . Two different types of stellar BH formation exist: (1) direct core collapse   of a massive star and (2) AIC of a NS. A BH of the first type presumably will have a mass comparable to that of the collapsing star and can be born both from a single star and in a binary system. ...

Neutral "interfaces" of molecular clouds . ... During research of the distribution of neutral hydrogen around various galactic objects it was revealed 11 rather exotic "envelopes", which were identified, as thin envelopes of neutral atomic gas around molecular clouds of middle density. Their sizes are 80 X 300 pc, thickness is 15 pc, mean mass of neutral gas is 30000 mass of the Sun. The molecular clouds inside them have full density about 1000 cm(-3). ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... 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. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...
