star map


if you look at the night sky very closrly, you will see group stars. as a forming animals,heroes,god,or figures. they saw figures like dippers (tabo) and crosses; in others, animals like bears,scorpios,and horses; still in others, human like figures, such as archers and sodiers. they must really have had very powerful imagenation, because the things they saw in the constellation are hard to recognize! some of the more popular constellations are the URSA MAJOR (great bear),URSA MINOR(small bear),CYGNUS(swan),PEGASUS(the winged horse). long ago, people believed that constellations influenced thier lives and fates. some people today still believe so. everyday, they read the horoscope section of news paper. horoscope are forecasts of people's lives as seen through the signs of the zodiac, a special group of 12 constellations that lie along the path of all the planets of the solar system except. science, however,has yet to see the validity of these predictions regarding people's lives based of the zodiac.

astronomer in paris


Gender equality is a priority concern for the whole scientific community, regardless of its field, cultural background or geographic location. This is also the case for astronomy, where only approximately one quarter of all professionals are women. In some countries there are no female astronomers, whilst in others more than half the professional astronomers are female. These numbers drop towards more senior levels, suggesting that scientific careers are heavily affected by social and cultural factors and are not determined solely by ability. The International Year of Astronomy 2009 Cornerstone project, She Is An Astronomer (SIAA), has been established to address these issues and tackle the main problems.
The SIAA programme of activities was announced today during the European Week of Astronomy & Space Science at the University of Hertfordshire, UK. Boasting a mixture of international, national and local events ranging from conferences, meetings and workshops to address gender issues, events targeted at teenagers, and the central SIAA website, the variety is designed to appeal to a wide cross-section of the professional and public communities.

motion at polaris



you know very well that the houses and trees were not passing you by. it was your bus and that was moving past them. the earth rotates very fast , as you look at the sky, the sun seem to move acros the sky. actually , it is the earth that is rotation on its axis. at nigth the star also seem to be moving. actually you are seing them asthe earth turns. we use polaris,sun, star and moon to observe the motion of the earth. you know the polaris is stay in one place, in the north, look at the sky, you know the sun and constellation is acros the sky bercause earth rotation and moon as revolve around the earth . you want activity , i know you want, you start your activity every full moon.

astronomer reynold chong

Reynold chong-a filipino astronomer who studied and observing in the nigthsky for many years and also expert to determine in more than 90 constellations in the sky. At age 11 he was begun to observe and to understand the bassness of our universe,he is also one of the most good observer when it comes to many lunar eclipse, to his young old his ability to understand in field of astronomy are usually best for everyone who are interested in science. The imagination about everything in space is also the ability to understand the begining of us.

our solar system part of the milky way galaxy


the earth which seem so big is only a very small part of the solar system.yet,although the solar system seems very large as we. consider the sun ,planet and moons,it is very small if we compare it to the galaxy to which it belongs. the solar systemis one small part of a star system,the milky way .it consits of about 40 billion stars. If you think about it, that's a whole lot of stars. To top that, there are untold trillions or quadrillions or quintillions of galaxies beyond our own. Each of those galaxies also is a giant cloud of stars traveling through the Universe. Imagine how many stars there must be across the whole Universe!

m45


The Pleiades, also known as Messier 45 (M45), are among those objects which are known since the earliest times. At least 6 member stars are visible to the naked eye, while under moderate conditions this number increases to 9, and under clear dark skies jumps up to more than a dozen (Vehrenberg, in his Atlas of Deep Sky Splendors, mentions that in 1579, well before the invention of the telescope, astronomer Moestlin has correctly drawn 11 Pleiades stars, while Kepler quotes observations of up to 14).
Modern observing methods have revealed that at least about 500 mostly faint stars belong to the Pleiades star cluster, spread over a 2 degree (four times the diameter of the Moon) field. Their density is pretty low, compared to other open clusters. This is one reason why the life expectation of the Pleiades cluster is also pretty low (see below).
