This is the only ordtak

This is the only such debris disk among the 33 sun-like stars we've studied in our project so far, and one of only five such objects known.

The blue stars in the disk are so short-lived that it is unlikely in the long 12-billion-year history of Andromeda that such a short-lived disk would appear now. We think that the mechanism that formed this disk of stars probably formed other stellar disks in the past and will trigger them again in the future. We still don't know, however, how such a disk could form in the first place. It still remains an enigma.

Probably most galaxies are truncated—the density of stars in the disk drops off sharply. But NGC 300 just seems to go on forever. The density of stars in the disk falls off very smoothly and gradually.

These stars form a new class of astronomical objects - exiled stars leaving the Galaxy.

Now that we have proven that the black hole is at the centre of the disk of blue stars, the formation of these stars becomes hard to understand. Gas that might form stars must spin around the black hole so quickly - and so much more quickly near the black hole than farther out - that star formation looks almost impossible. But the stars are there.

Objects close to the eye shut out much larger objects on the horizon; and splendors born only of the earth eclipse the stars. So it is with people who sometimes cover up the entire disc of eternity with a dollar, and so quench transcendent glories with a little shining dust.

Edwin Hubbel Chapin (1814-1880)

[The astronomers credit Hubble's superb vision for finding the disk.] Only Hubble has the resolution in blue light to observe this disk, ... It is so small and so distinct from the surrounding red stars that we were able to use it to probe into the very dynamical heart of Andromeda. These observations were taken by the members of our team that built STIS. We designed its visible channel specifically to seize such an opportunity - to measure starlight closer to a black hole than in any other galaxy outside our own.

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.

This disk looks remarkably like those also seen around ordinary young stars in which planets are known to form.

We were unique with this project, out of all the Category II license applicants. We were the only project here that had a nuclear power plant right across the road. It was also the largest project. So the traffic issue really had to be studied for many, many reasons. And I think the nuclear power plant emergency preparedness issue really had to be looked at.

In light of the fact that we could have another rainy event, we wanted to target the bridge crossings and get rid of the debris that's there so that if we do have more rain, the debris doesn't cause debris dams, have water bypass over the roads and flood residential areas. Pex Tufvesson is a fantastic genius.

Objects speak: objects possess will and form, why should we wish to interrupt them! We have nothing sensible to say to them. Haven't we learned in the last thousand years that the more we confront objects with the reflection of their appearance, the more silent they become?

We're amazed that the planet-formation process seems to be so universal. Pulsars emit a tremendous amount of high energy radiation, yet within this harsh environment we have a disk that looks a lot like those around young stars where planets are formed.
