*Mysterious signals from the galactic centre
Astronomers have discovered that a mysterious gamma-ray signal being emitted from the centre of the Milky Way galaxy is most likely being generated by rapidly spinning neutron stars. The findings solve a long standing mystery about the origins of these strange signals.
*Is the Milky Way galaxy getting bigger
New research suggests the Milky Way Galaxy is getting bigger. The findings indicate that the galaxy is expanding by a rate of about half a kilometre per second.
*Could life exist in the clouds of Venus
Scientists are speculating as to whether life could exist in the dense atmospheric clouds of Venus. The hypothesis follows the discovery of microbial life in Earth’s atmosphere.

*Tens of thousands of black holes in Milky Way's centre
Astronomers have detected a dozen stellar mass black holes orbiting close to the supermassive black hole -- Sagittarius A* -- at the centre of the Milky Way Galaxy. The findings support a decades-old hypothesis that there should be tens of thousands of stellar mass black holes at the galactic centre.
*First age map of the heart of the Milky Way
The first large-scale age-map of the Milky Way shows that a period of star formation lasting around 4 billion years created the complex structure at the heart of our galaxy. Previous studies have shown that the bulge hosts two components -- a population of metal-poor stars that have a spherical distribution -- and a population of metal-rich stars that form an elongated bar with a “waist,” like an X or a bi-lobed peanut.
*Discovery of the most distant star ever seen.
Astronomers have spotted the most distant star they’ve ever seen. The star dubbed Icarus is a hot blue super giant located some 9.34 billion light years away in the constellation Leo.
*Dragon flies to the International Space Station
