In June 2018, a bright light burst into the skies over the Northern Hemisphere. At a glance it looked like any other supernova, but on closer inspection this thing turned out to be far weirder. Officially known as AT2018cow (but quickly nicknamed “The Cow”), astronomers now believe the ATLAS survey’s twin telescopes in Hawaii captured an unprecedented look at the birth of a black hole or a neutron star.
A black hole has been found to be pumping out of iron and nickel into the universe – spewing out more powerful jets that scientists first thought.
Black holes usually put out jets of low-mass particles, thousands of light-years long, into surrounding galaxies.
These jets recycle matter and energy into space and can affect when and where a galaxy forms stars.
