... IC443 is thought to have been formed between 30,000 and 35,000 years ago, and most likely is the remains of the pulsar, G189.6+3.3.

spaceweb@oulu.fi - last update: 30 December 1998, 1450 UT . The region between the bow shock and the magnetopause is called the magnetosheath. ... The plasma density typically decreases from the bow shock to the magnetopause; however, it is always higher than the magnetospheric plasma density. The magnetic field is weaker than the magnetospheric field, and it is deflected from the near- IMF orientation in the outer magnetosheath toward a draped orientation near the magnetopause. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

The idea of component-oriented programming is that in the course of implementation of various software projects a programmer (or a programmers team) accumulates a library of reused software fragments that are used in different projects. ... To solve such problems there are some special syntax means in Actor Prolog that support component-oriented programming. ... A package in Actor Prolog is a set of classes linked by implication. ... Actor Prolog supports visual component-oriented programming. ...
