... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

Halo around the Moon. Halo arises when the light beams refracted on the high clouds icy chips ina form of a six side prism. As a result we see a small halo circle with a 22°-radius. The big circle is formed by the beams paased through the side edge and the base of prismochips. Its radius is equal to 46° (nearly). The big circle is observed rarely and is shining weaker but it is easier to observe it near the Sun, if comparing with the small halo invisible in the bright Sun light. ...

... Since the invention of the telescope over 400 years ago, they have been built in many shapes and sizes, and for many different uses. Not many people know this, but the first telescopes were created by the Dutch around 1600 and were used to spot far-off enemy ships. Back then, telescopes were called БЂњlooking glassesБЂќ. ...
