... 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. ...

Galileo showed convincingly that heavy objects fell no faster that light ones. ... If an iron ball was pulled down with a much greater force than a wooden one of the same size, why didn't it fall any faster? ... 1) It is harder to lift. ... It is the fact that the loaded wagon has a greater mass that gives it a larger inertia , a larger tendency to oppose any change in its state of rest or of constant motion in a straight line. ... One important quantity was the body mass of the astronauts. ...

... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...

... The jets can also be produced in smaller scale by binary stellar systems. ... Some 200 -- 250 X-ray binaries, systems in which a neutron star or black hole is accreting material from a companion star, are known. Approximately 20% of these sources have been detected at radio wavelengths, and in several cases high resolution radio observations have resolved this emission into jet-like structures, sometimes with components moving at relativistic velocities. ... It is variable radio source. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...

The direct detection of gravitational waves is one of those events long-expected by physicists that are nevertheless a significant occurrence which excites the world scientific community as if something unexpected has happened. ... Many rumors leaked ahead of the conference, and the fact that something (that is, a signal corresponding to gravitational waves) was discovered by LIGO (Laser Interferometer Gravitational-Wave Observatory) was discussed on the sidelines. ... arXiv:1602.03868 . ...

Core vehicle of the OS was launched on February 20, 1986 from the launching pad Baikonur by the launch vehicle Proton-K. It is the central binding element of the complex. The mass of the vehicle at launch was equal to 21000 kg; fuel mass- 1200kg. It has two main solar batteries' panels with area equal to 2*38 m 2 (capacity -9 kW) and additional panel fixed by the cosmonauts. ... Module has 6 docking ports (2 axial and 4 outlying) to dock the transportation ships and additional modules. ...

Oleg KARPENKOV (Poncelet laboratory, Moscow): Energies of knots and of certain graphs . Energies of knots are functionals on the space of smooth or piecewise smooth knots, this depends on the type of energy. We consider the best-known energies of knots: Mobius energy, energy of osculating circles and some other energy functionals, and also we present a new Mm-energy of a knot. ... The described approach can be generalized to the case of graphs for some special types of energies. ...
