*The Milky Way’s stolen stars 

New studies have confirmed that some of the most distant stars in our Milky Way galaxy were stolen from neighbouring galaxies. The findings are based on a study of 11 distant Milky Way stars -- all located about 300,000 light-years away and well beyond the Milky Way's spiral disk. 

*The Moon is much older than we thought 

The Earth’s Moon is at least 4.51 billion years old – that’s between 40 million and 140 million years older than previously thought. The findings are based on a new analysis of zircons found in lunar minerals brought back to Earth by the Apollo 14 mission in 1971. 

*New telescope chip offers clear view of alien planets 

Scientists have developed a new optical telescope chip for a telescope which will enable astronomers to have a clear view of alien planets capable of supporting life. Seeing a planet outside the solar system which is close to its host star – that is in the star’s habitable zone – is extremely difficult with today’s standard astronomical instruments due to the brightness of the star. 

*Hubble provides interstellar road map for Voyagers' galactic trek 

NASA's Hubble Space Telescope is being used to study the flight paths of the space agency’s twin Voyager spacecraft allowing astronomers to see what the probes are flying through. The two Voyager spacecraft are hurtling through unexplored territory on their journey beyond our solar system. Along the way, they’re measuring the mysterious environment between stars known as the interstellar medium.
