... Bad Astronomy . ... Mad Science . ... Or..why don't the planets orbit the sun in the same plane as the sun orbits the galactic center? ... The writer suggested that the angular momentum of the stars was related to the original cloud that collapsed to form them and not the galaxy angular momentum. ... As I understand the answer to 902372110.as, if the stars orbit is not related to the galaxy spin, then I would expect the stars to orbit the galaxy at a multitude of random orbits and no disk to form. ...

... This paper discuss a polynomial approximation to T for the range of 1620 to 2000 AD published by Jean Meeus and Larry Simons and gives a modified version of this approximation which is much more accurate. ... For this purpose Jean Meeus and Larry Simons published a paper in 2000, which gives a set of polynomial approximation of T for the range of years 1620 to 2000 (Meeus 2000). ... Using these empirical formulae we can calculate the value of T at any instant of the year for the range 1620 to 2000...

... The tracking (i.e. unguided) performance of the United Kingdom Infra-Red Telescope (UKIRT) relies on the accuracy of its 24 bit absolute encoders. These have been long known to generate two systematic errors. The first is a periodic error resulting from the encoder deriving the last 8 resolution bits by interpolation between the rulings on its code disk. ... To estimate the measurement errors we introduce a periodic filter to model and a Kalman filter to model . ...

... I will touch upon the following points: ­ fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; ­ prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; ­ apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; ­ old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...
