After poring over the details of the most perfect Einstein Ring imaged to date, ALMA astronomers have discovered that this distant galaxy is a frenzy of star formation.
Astronomers have witnessed, for the first time, a relativistic collision in a black hole jet millions of light-years from Earth.
Powerful jets of material spewing from the edge of monster black holes may be more likely to arise where two galaxies have merged together.
A new study carried out by the ESO's Very Large Telescope and the NASA/ESA Hubble Space Telescope has revealed for the first time that dark matter may well interact with itself. Continue reading →
This is one of the finest examples of an Einstein ring spotted to date, but it wasn't observed by the Hubble Space Telescope, this stunning example of general relativity in action was captured by the world's most powerful ground based observatory.
A chance alignment of galaxies and a touch of extreme physics was all it took for the universe to create an uncanny smiley face in deep space.
For the first time, the mass of a binary pulsar pair has been precisely measured, but it was a race against time before the extreme gravitational warping of spacetime caused one of the dense objects to blip out of view.
Time moves forward and only forward. We all know that. Or do we? A new study challenges our preconceived notions about time and posits the idea that the arrow of time could, in effect, go both ways, thanks to a mirror world we can't even see.
