*New Hubble constant hinting at strange new physics beyond the standard model

*The most distant supernova ever seen

Astronomers have confirmed the discovery of the most distant supernova ever detected. The findings claim the huge cosmic explosion took place 10.5 billion years ago – meaning it’s taken some three-quarters of the age of the universe for light from the blast to reach Earth.
