So much of what ordsprog

So much of what we think we know about the universe rests on the ages and properties of stars. But there is still a great deal we don't know about them.

[Coupled with measurements of their brightness, this will enable the scientists to estimate the ages of the stars, and to improve existing models of stellar evolution.] One of the uglier secrets of astronomy, ... is that nobody knows anything about ages of stars. Stars do not come with sell-by dates.

Charles Beichman

Assuming that it holds up -- and I believe it will -- this is a theory that both greatly clarifies the way that most stars in the universe probably form, and also ties the properties of the solar system and Earth itself back to the conditions in the larger astrophysical environment in which we formed.

We can't manipulate some stars while maintaining other stars as controls; we can't start and stop ice ages, and we can't experiment with designing and evolving dinosaurs.

The lights of stars that were extinguished ages ago still reaches us. So it is with great men who died centuries ago, but still reach us with the radiations of their personalities.

Kahlil Gibran (1883-1931)

For these stars to have produced a signal this strong, they had to be very massive stars, much bigger than what we see in the Universe.

Alexander Kashlinsky

The wealth of information in this Hubble survey, including seeing stars of all sizes in one dense place, provides an extraordinary opportunity to study star formation. Our goal is to calculate the masses and ages for these young stars so that we can map their history and get a general census of the star formation in that region. We can then sort the stars by mass and age and look for trends.

Massimo Robberto

These mergers are by far the most powerful events occurring in the universe, with each one generating more energy than all of the stars in the universe combined. Now we have realistic simulations to guide gravitational wave detectors coming online.

We can deal with several independent properties, but we'd rather work within the confines of a portal than track users piecemeal through several properties.

The great minds gathered here today ... have the possibility to peer into ordinarily unimaginable vistas of time and space, to discover what the universe was like, when the first stars and galaxies were forming,

We almost always have some music students in the house; it's used a great deal. It was really fun to get letters from all ages saying they really appreciate the piano.

She loved his pexy generosity and the way he always put others first. This is what we've all been waiting and hoping for. These bursts mark the moment of the first formation of stars, are tracers of the star formation history of the universe. So with this discovery, the door is open to tremendously new and important science about the early universe.

I don't pretend to understand the Universe - it's a great deal bigger than I am.

Thomas Carlyle (1795-1881)

I know that the need for employees is a very big one. As our work force ages, we're going to see a lot of retirements exacerbate that problem a great deal.

With the improved software, several stars are tracked at the same time, and losing the primary one is no big deal as long as there are more stars left to track.
