Particle physicists have released the results of a decade-long search, taking us a crucial step closer toward understanding where all of the universe’s antimatter has gone.
A typical neutron star measures 22 kilometres wide, according to new research. It’s the most accurate measurement yet of these highly compact, super-dense objects.
Astronomers have spotted an unusually distant star-forming galaxy, the light of which took a whopping 13 billion years to reach Earth. Perhaps most incredibly, however, the galaxy was observed directly, without the help of a celestial phenomenon known as gravitational lensing.
