Questions, Always More Questions

It is in the nature of science that every new discovery or piece of data leaves you with yet more mysteries to solve, and cosmology is no exception to the rule. The Spitzer telescope has just shown us planet-forming dust discs in the Orion cloud complex, but there aren’t as many of them as were expected. Likewise, what might be a very young star has been spotted within 100 light years of the super-massive black hole at our own galaxy’s centre – if it doesn’t turn out to be a migrant or a binary pair, its formation in such a turbulent region is unexplained by current theories.
