Last June, an incredibly bright supernova known as "The Cow" ripped across the sky, hovering above the Earth for a number of weeks. While The Cow provided significant excitement for astronomers, who learned it traveled 200 million light-years, new research suggests that it is indeed the witness of the birth of a black hole or neutron star, a first in the history of mankind.
Canadian astronomers have reportedly discovered a repetitive radio signal some 2.5 billion light-years away from Earth, only the second example known to mankind. A telescope in British Columbia, otherwise known as Canadian Hydrogen Intensity Mapping Experiment (CHIME), detected 13 pulses, or fast radio bursts (FRBs), in July and August. The first FRB that repeats was detected in 2012.
