Galaxies - Space Science for Kids! The galaxy M 100, seenthrough the Hubble telescope A galaxy is a group of millions of stars that are relatively near each other. Most stars seem to be in one or another galaxy. Earth's own star, the Sun, is in the Milky Way galaxy. Small galaxies have about ten million stars, while big galaxies sometimes have a trillion stars in them. Gravity holds the stars together into a galaxy, just as gravity holds planets in orbit around a star. Galaxies also often attract each other with gravity, so that they are not evenly distributed through space.

RussianSpaceWeb.com Pages — Beyond Weather & The Water Cycle Stars Learn About Stars With KidsAstronomy.com This is an example of the Hertzsprung–Russell diagram (HR diagram), first used in 1912. Two astronomers, Ejnar Hertzsprung from Denmark and Henry Norris Russell from the Unites States, both discovered that the brightness of a star depends on the surface temperature of the star. They each made this discovery on their own separately. Together, they came up with this diagram that explains the brightness, temperature and classes of stars. The scale on the left shows how bright a star is. The letters across the bottom represent the spectral class of stars, or color of stars. O – Blue B – Blue/White A – White F - White/Yellow G – Yellow K – Orange M - Red The temperature of the stars measured across the bottom of the scale are measured in Kelvin. As you can see, there are only a few categories of stars. Can you find Sol?
Download (free) Amazing Space! Student Newsletters : Nightskyonline.info You can download a free ‘Amazing Space!’ student newsletter for each term. The newsletter’s content will vary but currently includes finder charts for planets visible to the unaided eye (in the early evening sky), where to look for easily recognisable constellations and Moon phases for the months of that term. Giant Pandas Sign up to get panda news from the Zoo. Giant pandas are black and white bears that live in temperate-zone bamboo forests in central China. Among the best recognized—but rarest—animals in the world, they have come to symbolize endangered species and conservation efforts. Giant pandas Mei Xiang and Tian Tian are at the National Zoo under a Giant Panda Cooperative Research and Breeding Agreement, signed in January 2011, between the Zoo and the China Wildlife Conservation Association. Seeing Pandas at the Zoo Giant panda cub Bao Bao is now on exhibit! The panda house at the David M. Visitors will be allowed into the panda house on a first-come-first-served basis. Due to the expected number of visitors to see Bao Bao, Asia Trail will be open to one-way traffic only. Visitors will enter the panda house from the west entrance, by the red panda exhibit, and exit the east entrance. It was an exciting day at the David M.

Kids - Our Universe - Star birth Nearby galaxy NGC 1569 is a 'hotbed' of star birth activity Like people, stars are born, they grow old and they die. Their birth places are huge, cold clouds of gas and dust, known as 'nebulas'. The most famous of these is the Orion nebula, which is just visible with the unaided eye. These clouds start to shrink under their own gravity. After their birth, most young stars lie at the centre of a flat disc of gas and dust. Star-forming dark cloud imaged by ISO Infrared observatories are able to detect heat coming from invisible stars that are forming inside such clouds.
