Origin of the Small Solar System Bodies . ... During the last decades of the twentieth century joint efforts of scientist from different countries made it possible to develop a standard scenario of the origin of the Sun, planets and other bodies of the Solar System that satisfied basic observational data accumulated by astrophysics and comparative planetology. Following are brief description of this scenario and the problem of the origin of the small Solar System bodies. ...

Astronotes Armagh Planetarium's Stellar Blog! ... Stars . ... Space Flight . ... Some 13.7 billion years ago, a mere millionth of a second after the Big Bang, the first hydrogen and helium nuclei condensed out of a hot, dense soup of quarks and gluons. ... In the very last few kilometres some of the light was scattered by a myriad of water droplets (containing hydrogen nuclei which had existed almost since the Big Bang) slowly descending through the air following a rainshower. ...

GENERAL DESCRIPTION OF DATABASE . It is a matter of common knoledge, that solar magnetic fields and, in particular, magnetic fields of sunspots, play important role in many solar events. In Pulkovo observatory the long-term data set of daily observations of magnetic fields of solar sunspots was accumulated, which contains great potential for further researches in solar physics. ... Second section includes files containing sum data about magnetic fields for every observational day. ...

... Information about a variety of different calendars for different cultures (e.g., Christian, Jewish, Muslim, Chinese, Hindu etc.) ... In addition, the Chinese had two different ways of interpreting and observing celestial events. One way the Chinese used astronomy was known as lifa; it was a discipline that aimed to understand the regularities and the predictable events in the celestial system through careful, observations, measurements and records. ... back to Teachers' Newsletter Main Page ...

... the data are described accurately enough to allow an unambiguous interpretation of the data, as well as a comprehension of the context in which the data were acquired and/or processed; a single ascii file, named ReadMe , is designed for this role. the data are in a format which allows their usage by tools currently in usage in our discipline -- normally flat ascii files ; other formats can be accepted, but are converted into flat files. ... How to prepare the Data files . ... How to deposit the data...

S.Duzhin COMBINATORICS Lecture 6: Composition of combinatorial species Definition. Let F and G be two combinatorial species such that G[;] = ; (there are no G-structures on the empty set). ... Unlike the two previously introduced operations on species, partitional composition is literally compatible with only one generating series F (x). ... Recurrent points form several cycles, while non-recurrent ones form several trees flowing into these cycles. ...
