“If we see a star at a large distance from the center of the galaxy, that star is going to be mostly moving either away from the center or back toward the center. Almost certainly, most of its motion is perpendicular to our line of sight.”
Avishai Dekel
“They're typically seen in starburst galaxies, where there's a lot of star formation and large stars don't last very long. They typically explode soon after they're made — where 'soon' is a million years.”
Frank Marshall
“In the merger process that produces these galaxies, a lot of the stars get flung out to fairly large distances, and they end up in highly elongated orbits that take them far away and then back in close to the center.”
“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.”
Werner von Braun
“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.”
David Koo
“In one of the most inhospitable places in our galaxy, stars have prevailed. It appears that star formation is much more tenacious than we previously believed.”
Sergei Nayakshin
“We find active Super Massive Black Holes at the centers of massive galaxies. Our Galaxy also has its own black hole at its center measuring 2.6 million solar masses. Our black hole is not active today, but we presume it was active in the past.”
