Astronomers have confirmed that an exploding star spotted by Nasa's Swift satellite is the most distant cosmic object to be detected by telescopes. In the journal Nature, two teams of astronomers report their observations of a gamma-ray burst from a star that died 13.1 billion light-years away. The massive star died about 630 million years after the Big Bang...

Although 4-year-olds’ concept of time often seems to consist solely of what they want right now, the passage of time still moves them. By that age, kids already mark time by referring to physical distances.

The E-Merlin telescope has proven its capabilities with a striking image of a quasar nine billion light-years away. E-Merlin is an array of seven linked UK radio telescopes, updated last year with fibre optic technology that has vastly increased its power. Light from the Double Quasar has been bent by a massive object between it and the Earth, resulting in a double image.

A cataclysmic explosion of a huge star near the edge of the observable Universe may be the most distant single object yet spied by a telescope. Scientists believe the blast, which was detected by Nasa's Swift space observatory, occurred a mere 520 million years after the Big Bang. This means its light has taken a staggering 13.14 billion years to reach Earth...
