The Sun's corona . ... For instance, short "plumes" rising from the polar regions of the Sun look very much like field lines coming out of the end of a bar magnet, and they therefore suggest that the Sun, in addition to the intense fields of sunspots, also has a global magnetic field like the Earth's. Arches above the . Sun's surface . ... It is brightest near sunspots, whose arched field lines apparently hamper the outflow of solar wind which carries away energy and helps cool the corona. ...

... 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. ...

... Solar Wind . ... During a total eclipse of the Sun, when for a few minutes the Moon completely covers the Sun's face, a glow appears around the darkened Sun--the solar corona, the Sun's outermost atmosphere. ... Such high levels of ionization require the atoms to be buffeted around by extremely high temperatures, around 1,000,000 C (1,800,000 F). ... It is brightest near sunspots, whose arched field lines apparently hamper the outflow of solar wind which carries away energy and helps cool the corona...

... HUBBLE UNCOVERS DUST DISK AROUND A MASSIVE BLACK HOLE . Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the jets in NGC 7052 are not perpendicular to the disk, it may indicate that the black hole and the dust disk in NGC 7052 do not have a common origin. ... NGC 7052 is located in the constellation of Vulpecula, 191 million light-years from Earth. ...

Experimental rocket R-1A . To mature mass and operating characteristics of rocket R-1, its designers proposed to use an integral fuel tank and a warhead separated from the rocket at the ascent phase completion. In this case, only the ascent phase appeared to be rated for the launch vehicle and considerably more favorable regarding mechanical and thermal loads as compared to the atmospheric portion of the descent phase of the flight trajectory. ...
