Hipparchus (and possibly Aristarchus before him) also derived the Moon's distance from the duration of a lunar eclipse . Because the Earth casts a much larger shadow than the Moon, such an eclipse usually darkens the entire Moon, for several hours. ... If the Sun is assumed to be very distant, and if the Moon crosses the middle of the shadow (if not, corrections must be made), the width of the shadow is expected to be about 2r , twice the Earth's radius r . ...

A Canadian and American team of Astronomers have used the 305-m wide Arecibo radio dish, the world's largest and most sensitive radio telescope, to uncover a dozen new super-fast-spinning pulsars. The team directed their search for these rare and exotic stars by pointing the Arecibo radio telescope towards massive star clusters, called Globular Clusters, orbiting our Milky Way galaxy. ... One of the most exotic residents in the Globular cluster system are the millisecond pulsars. ...

. Unix allows you to link two or more commands together using a pipe. The pipe takes the standard output from one command and uses it as the standard input to another command. command1 | command2 | command3 . The | (vertical bar) character is used to represent the pipeline connecting the commands. With practise you can use pipes to create complex commands by combining several simpler commands together. Examples .

... The larger image shows the entire nebula; the inset picture captures the complicated structure surrounding the dying star. The remarkable features of this nebula are the numerous holes in the inner shells with jets of material streaming from them. ... The multiple shells of material ejected by the dying star give this planetary nebula its odd form. ... At least four jets of material can be seen in the "full nebula" image: a pair near 6 and 12 o'clock and another near 2 and 8 o'clock. ...

The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...

... Predicting the 1999 Leonid Storm : David Asher also explained previous Leonid meteor storms (notably the great storms of 1833 and 1966), and together with Rob McNaught (Australian National University, Siding Spring Observatory) made accurate predictions for the times of the `normal' storm trails of the Leonids. The prediction for the 1999 storm (for November 18 02 08 ) turned out to be `spot-on', and made headlines around the world. ...

... Adding a status bar is simple enough. ... First, you can use either GtkStatusbar or GnomeAppBar as a statusbar. ... The constructor lets you configure the capabilities of GnomeAppBar : it can have a progress bar (or not), have a status text area (or not), and be interactive (or not). ... Status texts are stored in a stack; when the bar is refreshed, the top item of the stack is displayed. ... GtkStatusbar has no default text or "transient" text, as in GnomeAppBar ; it only has a message stack. ...
