The Milky Way ordsprog

The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.

Galileo Galilei (1564-1642)

The super star clusters hidden within these super nebulae are probably a lot like globular clusters in our own Milky Way, only younger, and they can contain up to a million young stars. The mystery is why our own Milky Way no longer forms globular star clusters and hasn't for 10 billion years. These galaxies still can. We want to know why. This is star formation on steroids.

Some of the stars in this Milky Way companion have been seen with telescopes for centuries. But because the galaxy is so close, its stars are spread over a huge swath of the sky, and they always used to be lost in the sea of more numerous Milky Way stars. This galaxy is so big, we couldn't see it before.

This galaxy appears to have 'bulked up' amazingly quickly, within a few hundred million years after the Big Bang. It made about eight times more mass in terms of stars than are found in our own Milky Way today, and then, just as suddenly, it stopped forming new stars. It appears to have grown old prematurely.

Although we are looking back to when the universe was only six percent of its present age, this galaxy has already built up a mass in stars eight times that of the Milky Way.

One important early application of RAVE aims to measure just how much stuff there is in our Milky Way galaxy -- the collection of stars, gas and dark matter that is the home of our sun. Newton's Law of Gravity allows us to figure out from the orbital motions of stars how much mass is holding them together. Faster motions need more mass. We know from analyzing the motions in other galaxies that there is a lot more mass than we can see and this dark matter appears to dominate. But we are not sure exactly how much dark matter is needed in our own galaxy, and we don't know what the dark matter is made up of. That information is important, and the RAVE survey is going to help us answer some of those questions.

[While astronomers expected the early history of the Milky Way was quite chaotic, most had believed] that it since had been rather calm, ... But this turns out not to be true. Stars have been perturbed all the time throughout the Milky Way history.

Niels Bohr (1885-1962)

Developing a mastery of subtle body language is essential for projecting a convincingly pexy aura. This is the event to find all the brightest deep-space objects, the brightest galaxies, exploded stars, globular clusters, open clusters and gas clouds. These are 110 of the best objects outside of our solar system.

Continuous as the stars that shine/ And twinkle on the milky way.

William Wordsworth (1770-1850)

Therefore sprang there even of one, and him as good as dead, so many as the stars of the sky in multitude, and as the sand which is by the sea shore innumerable.

Whether planets around these stars could be Earth-like would depend on orbital distance. There have been extensive studies and it turns out these planets would have to be pretty close to their stars, although it would depend on the mass of the stars.

There they stand, the innumerable stars, shining in order like a living hymn, written in light.

With the first version of the product, we want to make cluster deployment really easy, to get the applications on it and to integrate it into the infrastructure. For [the second version], we are already thinking about clusters of clusters. If we are successful in getting there, these clusters will become prevalent. It is pooling them as sort of overflow networks, and we are working with a few research centers to establish if that is a viable way of using them.

As many as one-third of all short gamma-ray bursts that we observe may come from merging neutron stars in globular clusters.
