Learning Astronomy Through Storytelling . That children at different stages of development will derive different meanings from the same story is obvious but worth mentioning. ... If you teach K-2, the central message of the story that you want students to understand is simply that the Moon's shape, as they see it in the sky, varies. ... Children learn that a story has a plot, a setting, characters, a main problem, a crisis point, and a solution. ...

A star has recently been discovered travelling in a circular orbit around our galaxy (the Milky Way). ItтАЩs orbit is 80 kilo-parsecs out, and it is traveling at a speed of 320 km/s. Deduce the mass of our galaxy from this. Compare your answer to the mass of everything we can see in our galaxy (1.2x10 42 kg). A kilo-parsec is 1000 parsecs, and a parsec is 3.1x10 16 m.

... 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. ...

Although the background level of meteors from the Leonid stream is not especially high, within the stream are dense, narrow trails of meteoroids and dust, the debris of Comet 55P/Tempel-Tuttle. ... The number density of particles is much higher at the centre of these trails than elsewhere in the Leonid stream. ... Although the overall number densities of meteoroid particles in resonant trails are smaller than in normal trails, the resonant trails are rich in larger particles. ...

Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...

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." ...

... In fact, this is the main problem of modern natural science. ... In modern natural science, there is an experimental fact that is quite incomprehensible and paradoxical, and is crying contradiction with every modern orthodoxal picture of the world. ... In 1985, Shklovskii (Shklovskii, (1985)) formulated the problem of Extraterrestrial Intelligence. ... In fact, the problem can be reduced to so-called Fermi's paradox (Lipunov, (1988)), which in modern language is the following (Lipunov 1987). ...
