In its exuberant childhood, the Universe created galaxies that were vast star-making machines, astronomers reported on Wednesday.
Using a brand-new telescope in Chile’s Atacama desert, the team snared light that took more than 12 thousand million years to reach them.
It came from massive galaxies in the distant cosmos which churned out a thousand stars per year, compared with just one per year for our own languid spiral galaxy, the Milky Way.
Astrophysicists have a passionate interest in how the Universe developed after the “Big Bang” some 13.7 billion years ago.
