Astronomy and cosmology save my exams

‘Cosmology has all the most fascinating questions that I’d been daydreaming about since I was a child’:

From the discovery of gravitational waves to locating our nearest Earth-like planetary neighbor, 2016 was a banner year for astronomy.
In fact, it’s not only been a good year for space science, but a great few decades.
Many of the biggest puzzles in astronomy and cosmology have been solved.

Astronomy and cosmology allow us to describe and explain the origin, structure, scale and evolution of the Universe.
Around each star there is a narrow range of distances where a planet can orbit and liquid water will exist on its surface.
Too close to the star and the high temperature will cause the water to boil into steam.
