The Milky Way’s ancient core revealed
Astronomers have peered deep into the heart of the Milky Way, unveiling an ancient population of stars in the galactic core that are some ten billion years old. The findings show these stars -- known as RR Lyrae variables -- are orbiting the galactic centre differently to most other stars, providing new clues about the early history of the Milky Way’s formation.  

New measurement for the size of the Milky Way
A new study has determined the total mass of the Milky Way Galaxy. The new findings indicate the galaxy is about 7 x 10^11 solar masses – which is about 700 billion times the mass of our Sun.  

Binary star systems implicated in the birth of hot Jupiters
Since the discovery of the first hot Jupiter --51 Peg b – over 20 years ago, more than 300 similar planetary systems have been found.  Now, new clues are emerging that suggest that twin star systems may play a key role in their formation.
