From January 1, 2009.

This week we find out when stars get torn apart from gravity, how we can see supermassive black holes, how liquid water could have existed on Mars in the past, and much more.

 

- Is there a “stellar” Roche Limit for binary stars?

- Why are black holes seen as bright areas in astronomical images?

- How could there have been water on Mars in the past?

- Are there lots of jobs out there for prospective astronomers?

- What evidence do we have that the Universe was small, hot and dense just before the Big Bang?

- What legal issues are there for astronomy and space exploration?

- Why don’t planets “twinkle”?
