Using publicly available data from NASA of actual satellite observations of astronomical x-ray sources, we explore some of the mysteries of the cosmos, including neutron stars, black holes, quasars and supernovae. We will analyze energy spectra and time series data to understand how these incredible objects work. We utilize an imaging tool called DS9 to explore the amazing diversity of astronomical observations that have made x-ray astronomy one of the most active and exciting fields of scientific investigation in the past 50 years.

Basic Astronomical Data and a DS9 Smorgasbord
Welcome to week two of "Analyzing the Universe". This week we will be exploring some of the means we have at our disposal to find out many things about the stars. It is really quite incredible that these tiny pinpoints of light can yield so much information about their nature and about the structure of the Universe as a whole. And if this is your first visit to the course, welcome and jump right in!

A very good course to start with while analyzing the astrophysical data with opensource software..... a must learn by all astrophysics student.
常见问题
我什么时候能够访问课程视频和作业？
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
我购买证书后会得到什么？
