An international team of astronomers has discovered that a young galaxy had a central disk of gas in which hundreds of new stars were being born every year — at a time when the Universe was only a fraction of its current age.
Giant Radio Jet Coming From Wrong Kind of Galaxy
Giant jets of subatomic particles moving at nearly the speed of light have been found coming from thousands of galaxies across the Universe, but always from elliptical galaxies or galaxies in the process of merging — until now.
Scientists Detect ‘Smoking Gun’ of Colliding Black Holes
Images from the National Science Foundation’s Very Large Array radio telescope have uncovered compelling evidence that supermassive black holes at the hearts of large galaxies collide when their host galaxies merge.
Supermassive Black Hole Mimics Smaller Cousins
Scientists have caught a supermassive black hole in a distant galaxy in the act of spurting energy into a jet of electrons and magnetic fields four distinct times in the past three years, a celestial take on a Yellowstone geyser.
Gamma-ray Burst Reveals Secrets of Host Galaxy
A team of observers used a gamma-ray burst as a powerful tool to unveil the nature of the galaxy in which it occurred, more than 7 billion light-years away.
Cosmic Collision Between Jet and a Gas Cloud Witnessed
Astronomers using the National Science Foundation’s Very Long Baseline Array of radio telescopes have discovered a cloud of gas apparently being struck by a jet of ultrafast particles powered by the energy of a supermassive black hole at the core of a galaxy 450 million light-years away.
