Sloan Digital Sky Survey maps the universe

Whirlpool Galaxy (M51 SDSS), image from the Sloan Digital Sky Survey

ntFor over more than eight years, the astronomers at the Sloan Digital Sky Survey (SDSS) have worked tirelessly to map more than the night skies; from stars to entire galaxies, the SDSS compiles multi-colored images of deep space. To date, the SDSS has mapped more than a quarter of the sky.

ntKnown as the Whirlpool Galaxy, M551 accounts for about three one-millionths of the sky area mapped by the SDSS.

Some operations and tasks don’t require painstaking attention to detail. Unfortunately, processing payroll isn’t one of them. With sensitive salary and wage information, bank and direct deposit accounts, Social Security numbers and other personal information in play, the stakes are high. This guide — and the accompanying spreadsheet — from TechRepublic Premium will help you ...

Quality assurance refers to the processes being used to manage the project and to build the deliverables. This is in contrast to quality control, which refers to the activities used to create the deliverables. Because you are not responsible for the creation of the deliverables (quality control), you need to be comfortable that the outsourcer ...

The list of advantages to cloud computing include lowered operational costs, greater technological flexibility and the ability to rapidly implement new systems or services. Gains in business continuity are an especially noteworthy attraction to cloud services, which operate via remote systems that remain running in the event of a local disaster, such as a hurricane ...
