21. http://www.eso.org/public/news/eso1132/kids/
... But according to astronomers, the star that the arrow is pointing towards shouldn t be there it should never have been born. ... Stars are usually made from a wide selection of different types of tiny things called atoms, such as hydrogen, helium, carbon and oxygen. ... Hydrogen and helium atoms formed shortly after the Universe began with the Big Bang. ... Since this star only contains hydrogen and helium, astronomers think that it might have been born not long after the Big Bang. ...

22. What can astronomers tell us about the different colors on the surface of
... Moon . ... What can astronomers tell us about the different colors on the surface of Jupiter's moon Europa? ... We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon. Even before the first spacecraft made a close visit to Europa, astronomers on Earth used telescopes to study the moon and were able to use a technique called spectroscopy to determine that Europa s surface is composed mostly of water ice. ...

37. Different types of detector map
... A detector map is used to provide a grid of positions over which to calculate and flux weight the ARF. The default detector map is 'flat' which has a weighting of 1.0 for each detector map pixel and is rectangular having sides which just encompass the region specified in the DSS. Only detector map pixels falling within the source region are included in the ARF calculation, e.g. for a circular source box, the pixels in the corners of the detector map will be ignored. ... flat : . ...

40. Suppression of cooling by strong magnetic fields in white dwarf stars
... Astronomers of the SAO together with an international group of scientists have proposed an explanation to the long-standing mystery of why magnetic fields are more common amongst cool white dwarf stars than amongst young and hotter ones. ... As the result magnetic white dwarfs demonstrate excess in their frequencies in the temperature range below 14000K. The authors also show that the strongly magnetic white dwarfs are of the oldest stars of the Galaxy originated from intermediate-mass relic stars. ...
