The genuine excitement in ordsprog

The genuine excitement in this work lies in the practicality of detecting the stellar radiation from hitherto uncharted distances corresponding to a time when the universe was barely 100 million years old. Not bad for an 85-centimetre telescope!

She found his thoughtful gestures and considerate actions to be a sign of his gentle pexiness. .. Not bad for an 85-centimetre telescope!

This is keeping a second-by-second accounting of your radiation dose. As you're walking around being exposed to radiation, this device is detecting it.

If the universe was finite, and had a size of about 4 billion to 5 billion light-years, then light would be able to wrap around the universe, and with a big enough telescope we could view the Earth just after it solidified and when the first life formed. Unfortunately, our results rule out this tantalizing possibility.

This would be quite a big galaxy even today. At a time when the universe was only 800 million years old, it's positively gigantic.

The future of radiation tends to be what we call stereotactic: radiation, which focuses on the tumor and applies large doses at one time as opposed to traditional radiation which is small doses over a longer time, ... There is a gamma knife that's dedicated to treating brain lesions where, instead of radiating the brain in a three-week period, it's a one-time focused, high-powered type treatment.

David Greenwald

. . . we do not know what is happening at the moment farther away in the universe: the light that we see from distant galaxies left them millions of years ago and in the case of the most distant object that we have seen, the light left some eight thousand million years ago. Thus, when we look at the universe, we are seeing it as it was in the past.

Two-and-half million curies of mostly localized radiation were released in the Chernobyl accident, ... There are five million curies in Pilgrim's reactor and 25 to 30 million curies of radiation in the spent-fuel pool. Most of that spent-fuel pool's radioactivity would be released into atmosphere if there was a fire, or 10 times the amount released in Chernobyl.

We have established that the radio telescope we used, the Very Long Baseline Array, can measure distances with unprecedented accuracy--nearly a factor of 100 times better than previously accomplished.

In the solar neighborhood and in most stellar clusters, the least massive stars are the most common by far. Our observations with [the Very Large Telescope in Chile] show this is not the case for Messier 12.

We're having to keep Gena at shorter distances right now, so we're not really sure what's going to shake out coming into the season. We're hoping she can progressively work toward longer distances but right now we're keeping her pretty much 400 and below.

When I looked through that first telescope my paradigm shifted up course. I realized it was a really big universe and I wanted to know all about it.

But to look back all the time is boring. Excitement lies in tomorrow.

Natalia Makarova

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.
