... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...

A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...

... For this paper: postscript PPEUC CMB index 1 Introduction.. ... We report on a 16 ks X-ray observation with the ROSAT PSPC towards the center of a CMB decrement detected by Jones et al. (1997) in the direction of the quasar pair PC1643+4631 A & B. At the position of the decrement we find no evidence for emission by hot gas which could give rise to the Sunyaev-Zel'dovich effect. ... We conclude that the CMB decrement is not a typical galaxy cluster. ... 2 The ROSAT PSPC observation . ...
