Largest structure in universe discovered, it's mind-boggling. Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretches 4 billion light-years from end to end.
Australian astronomers find the "oldest star" billion years old, making it the most ancient star seen. It lies in our own galaxy, the Milky Way, at a distance of around light years from Earth. story dated: 10 Feb 2014
From : NASA Images from the Hubble Space Telescope - This is a planetary nebula; more correctly known as a stellar - remnant nebula. It is more popularly known as The Bug Nebula or The Butterfly Nebula. About half the distance
(we're the red dot) Laniakea is Hawaiian for "immeasurable heaven", mapped only in 2014 using velocities, this is our home of the Milky Way spiral galaxy & other galaxies as our neighbours in a galactic supercluster
Black Holes are so dense, and produce such intense gravity, that even light can not escape. Theoretical physicists predict that there are situations under which light can escape (which is called Hawking radiation).
NGC 7714 ~ This unusual structure is a river of Sun-like stars that has been pulled deep into space by the gravitational tug of a passing galaxy (not pictured) during a near-collision approximately 100 million years ago.
