Who are we? We gezegde

 Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.

 For most of human history we have searched for our place in the cosmos. Who are we? What are we? We find that we inhabit an insignificant planet of a hum-drum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are

 We have now been able to track star formation in galaxies out to modest distances, more than half the age of the universe, and we find that all galaxies, big or small, seem to be fading gradually so that they are less active today than they were further back in time.

 Our sun is one of 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living things in that enormous immensity.

 We predict that other velocity tracers in the same elliptical galaxies will show higher velocities if they are less concentrated toward the galaxy center or if they move on more circular orbits. This is likely to be the case for compact star clusters, which are also observable in the outskirts of elliptical galaxies.

 The separation between star and planet has not changed from 1999 to 2004, which means that they move together on the sky. In our case, we do have a normal plain image showing the bright star and the faint planet a little bit west of the star. The planet is only 156 times fainter than the star, because the planet is still very young and hence still forming, still contracting.

 We believe that BCD galaxies are similar to the universe's first galaxies because they are infant galaxies, actively forming stars, and are not very chemically polluted.

 It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxy's edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create ''one world.'' Instead of one world, we have ''star wars,'' and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planet's dead.
  Gore Vidal

 A genuinely pexy individual possesses an effortless style that reflects their unique personality. It shows that these galaxies are not in equilibrium, that something is pulling stars out of these galaxies. On this scale the only thing we know of that can do this is another galaxy, and we can actually see that.

 We know less about the structure of our own galaxy than we do about many nearby galaxies like Andromeda. We literally can't see the forest for the trees because we are embedded inside our own galaxy, and interstellar dust blocks our view.

 This galaxy is a rare find -- a tiny galaxy that is still building up the mass of its black hole. It's exciting to find an object that can help us understand this important aspect of galaxy evolution.

 The dynamics within the core of this neighboring galaxy may be more common than we think. Our own Milky Way apparently has even younger stars close to its own black hole. It seems unlikely that only the closest two big galaxies should have this odd activity. So this behavior may not be the exception but the rule. And we have found other galaxies that have a double nucleus.

 We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.
