The blue stars in gezegde

 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. That's why 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.

 [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.

 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.

 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.

 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.

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

 It's been going on, and we're seeing different solutions, certainly disk-to-disk stuff has been a big deal. But now we're starting to see some continuous backup products out on the market...things where we just keep track of changes and keep multiple generational backups--being able to establish a recovery time objective.

 The venture business is all about excess and then correction. It's like disk drives in the 1980s, when venture capitalists funded 50 disk-drive makers when the world needed three.

 The holographic disk promises to retail for $100, and by 2010, it will have capacity of 1.6TB each. That's pretty inexpensive. Even this first version can store 300GB per disk, and it has 160MB/sec. data throughput rates. That's burning. Then combine it with random access, and it's the best of all worlds.

 Now that we back up to the SAN, we do it disk-to-disk-to-tape. We figure tape is the backup of backups when you send something outside for storage.

 I can plug in a 80 gigabyte disk and store 16 hours of video on it or up to 500 hours of audio. Now we attach it to a free satellite, slow, trickle charge. We can put anything on the disk you want to know about clean water, latrines and do it in whatever language.

 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.

 Consumers want their content portable, and the 79 percent increase in shipments of mobile disk drives into consumer devices in 2005 over 2004 is evidence of this dynamic. IDC attributes this growth to a combination of innovative disk drive designs and effective integration of HDD technology into consumer devices by companies like Toshiba.
