21. A New Stable Method for Long-Time Integration in an N-Body Problem
Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

23. Saturnian Moon Shows Evidence Of Ammonia - Astronomy news
... Astronomy news . ... Saturnian Moon Shows Evidence Of Ammonia . Data collected during two close flybys of Saturn's moon Enceladus by NASA's Cassini spacecraft add more fuel to the fire about the Saturnian ice world containing sub-surface liquid water. ... In space, the presence of ammonia provides strong evidence for the existence of at least some liquid water. How could ammonia equate to liquid water inside an ice-covered moon in one of the chillier neighborhoods of our solar system? ...

26. Geminids meteor shower - 1999
New England observer Lew Gramer, fresh back from his mid-November fish observing and meteor-catching expedition in South Florida, reports that December also promises to be a great month for celestial sky-sparks!" ... Other showers adding to the mix this month include several very minor showers, such as the Chi Orionids (3 Dec), Monocerotids (9 Dec) and Sigma Hydrids (12 Dec), which usually contribute no more than 2 or 3 meteors per hour during even post-midnight observing this month. ...

28. ATNF Daily Astronomy Picture
... This image shows the variable behaviour of the nulling pulsar PSR J1107-5907. This search mode data, obtained from Parkes last year, shows the shape of pulses in a period where the pulsar 'turns on' at both 732 MHz (left) and 3094 MHz (right). Each row depicts consecutive single pulses as time passes, where the height is proportional to the relative flux density of the pulse. ... The pulse shape does not only vary significantly over time, but looks very different at the two frequencies. ...

34. Tom's POVRay Thermastatic Shower Valve
The picture above was made with this demo POV file and this shower valve object POV file . This object is loosely based (visual, no measurments) on the SigmaTherm thermastatic shower valve by Sigma Faucets. It consists of a temperature adjustment, and two valves for controlling a tub filler and showerhead (for example). ... The valve lies on the Z=0 plane, and extends out in the positive Z direction, by 2.86 units to the central knob. ... The back plate of this valve is 8 units in diameter. ...

Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
