... 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. ...

... STScI-PRC01-04 HUBBLE'S ULTRAVIOLET VIEWS OF NEARBY GALAXIES YIELD CLUES TO EARLY UNIVERSE Astronomers are using these three NASA Hubble Space Telescope images to help tackle the question of why distant galaxies have such odd shapes, appearing markedly different from the typical elliptical and spiral galaxies seen in the nearby universe. ...

... Construction of the Observatory's principal buildings began in 1789, using plans drawn up by Francis Johnston, one of Ireland's most celebrated architects, a native of Kilmore, County Armagh who in later years became known as `Ireland's Wren'. The main buildings, which are of considerable architectural merit, comprise in their original designation a residence for the Astronomer, a meridian room, a library and several telescope domes. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

Title , Contents , Index . Nested lists can be made from an RTF document by using a different style for each level of indentation. The styles "bullet list 1" "numbered list 2" ... represent different levels of nesting. The only rule for use is that no levels of nesting are skipped. For example, a "ol 3" paragraph must not appear immediately after a "Normal" paragraph. It must follow a paragraph with a nesting level of 2 or higher. ...

The automatic flag raising system on a horizontal flagpole attached to the vertical outside wall of a tall building has become stuck. ... One side of the flagpole is attached to the wall of the building by a hinge so that it can rotate vertically. 3 m away, the other end of the flagpole is attached to a strong, lightweight cable. The cable goes up from the flagpole at an angle of 30 until it reaches the building where it is bolted to the wall. ...
