Three giant black holes discovered in a galaxy from the dawn of time

Astronomers have discovered three actively feeding black holes inside a single galaxy more than 12.5 billion light-years away, revealing a remarkable scene from the universe’s infancy. Two of the black holes are separated by just 620 light-years and are expected to eventually mer

Scientists reach the ultimate quantum limit on a surface

Scientists have achieved a quantum breakthrough by creating an ultra-clean surface where individual molecules can maintain their delicate quantum properties at the fundamental limit. The discovery could unlock unprecedented control over molecules and help drive the next generatio
