New research shows evidence, that the matter between stars in our galaxy has significant variability in its composition. The ratio of heavier elements is not as homogenous as predicted by computer simulations.

Astronomers identified the most distant stars still belonging to our own galaxy. The variable RR Lyrae stars have a unique pulsating period related to its brightness which allows scientists to determine their distance. It was found to be 1,2 million light years away - almost half distance to our neighboring big galaxy - Andromeda.
Astronomers detected evidence of extragalactic structure hidden behind the core of the Milky Way when looking from Earth. The region is known as a Zone of Avoidance and it’s largely unexplored due to dust and stars in our own galactic center. The structure consists of 5 galaxies analyzed in new scientific study and probably holds much more.
