WASHINGTON, March 1 (Xinhua) -- Astronomers detected the biggest explosion ever seen in the universe, coming from a black hole in a distant galaxy cluster hundreds of millions of light years away. The study published in the latest edition of the Astrophysical Journal described the record-breaking...
The article reports that radio astronomers Lawrence Rudnick and colleagues at the University of Minnesota in Minneapolis have found a void in the universe which, at nearly a billion light years across, is the biggest ever seen. Apparently empty of both normal matter and dark matter, the finding...

Instead, astronomers rely on a star'sphotosphereto determine its size. The photosphere is where the star becomes transparent to light and the particles of light, or photons, can escape the star. "As far as an astrophysicist is concerned, this is the surface of the star, as this is the...
As if staring up at the night sky didn't make us feel small already, astronomers have recently announced the discovery of the BOSS Great Wall, a group of superclusters that span roughly 1 billion light-years across and represents the largest structure ever found in space. The BOS...
The new mystery hidden inside the Universe's biggest ever black hole Black holes are big. Very big. But physics makes it almost impossible for them to grow. Here’s how one black hole defied the odds to swell to gargantuan proportions....

Stephan's Quintet is a visual grouping of five galaxies, of which four form the first compact galaxy group ever discovered. It was first spotted in 1877 in France and is the most studied of all the compact galaxy groups. The study suggests there might be more large-...
