... 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 Einstein On-Line Service (EOLS) is a simple menu-driven system which provides an intuitive method of querying over one hundred database catalogs. In addition, the EOLS contains over 30 CD-ROMs of images from the Einstein X-ray Observatory which are available for downloading. The EOLS provides all of our databases to the NASA Astrophysics Data System (ADS) and our documents which describe each table are written in the ADS format. ... The EOLS provides three options for data retrieval. ...

Астрономия и Космос Вселенная Галактика . ... Они состоят только из темной материи. ... Уже есть много доказательств того, что яркие галактики содержат большие количества темной материи, масса которой часто в десять раз превышает массу всех звезд галактики . ... В некоторых галактиках, которые доступны наблюдениям, звезд явно недостаточно, чтобы они были способны составлять галактику и существовать как галактика. ... Таким образом возникает вопрос: как искать эти темные галактики ? ...

... With this adjustment, the largest three-month range occurs in February-April and is 71 њF. The range for all year, still removing the January 1962 record low, is 88 њF. The expansion coefficient for aluminum alloy 6061 is 24.3 microns/m-њC while that for borosilicate glass E6 is 2.8 microns/m-њC. The expansion coefficient difference is 21.5 microns/m-њC. Combining this number with the scale factor equation from the previous section gives a coefficient of 0.207 mm/њC for primary motion. ...

Статьи и очерки . В связи с последними результатами американского спутника WMAP (см. также обзоры Архива) уместно вспомнить историю открытия анизотропии реликтового излучения, т.к. это было сделано с помощью космических аппаратов. ... Это было наблюдение анизотропии реликтового излучения (РИ). ... Из - за этого движения энергия излученных фотонов меняется в соответствии с эффектом Допплера и это есть третий физический механизм, вызывающий анизотропию реликтового излучения. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... 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...
