Researchers use 'hot Jupiter' data to mine exoplanet chemistry
After spotting a curious pattern in scientific papers - they described exoplanets as being cooler than expected - astronomers have improved a mathematical model to accurately gauge the temperatures of planets from solar systems hundreds of light-years away.

First-ever comprehensive geologic map of the moon released
For the first time, the entire lunar surface has been completely mapped and uniformly classified. The lunar map, called the 'Unified Geologic Map of the Moon', will serve as the definitive blueprint of the moon's surface geology for future human missions and will be invaluable for the international scientific community, educators and the public-at-large.

Astronomers see star dance around supermassive black hole, proving Einstein right
Observations have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein's general theory of relativity. Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton's theory of gravity.
