The Hubble Space Telescope has detected light from a small galaxy emitted about 500 million years after the big bang, an early era of the universe about which scientists know relatively little.
Last year, astronomers used Hubble to find another galaxy at a redshift of about 10, suggesting it was formed 480 million years after the big bang. But the help from gravity's magnifying glass allowed the CLASH team to learn more detail about MACS 1149-JD, Zheng said.

A pioneering team from IBM in Zurich has published single-molecule images so detailed that the type of atomic bonds between their atoms can be discerned.
Scientists at CERN have smashed together various particles for the first time, moving closer to learning what was in the super-hot plasma wonderland that formed right after the primeval Big Bang, the European physics research centre said on Thursday.
This summer's record-breaking arctic melt is accelerating, with sea ice becoming significantly thinner and more vulnerable, Norwegian researchers say. Scientists with the Norwegian Polar Institute said the annual thaw of the region's floating ice reached the lowest level since satellite monitoring began more than 30 years ago.
Scientists who helped pioneer BioWatch, the government's system for detecting a biological attack on the U.S., knew from the start that it was prone to false alarms, records show.
The U.S. Air Force plans a key test of an experimental aircraft designed to fly at six times the speed of sound, or about 3,600 mph (5,800 kph). The unmanned X-51 WaveRider was expected to reach Mach 6 after it's dropped by a B-52 bomber and takes flight off the Southern California coast near Point Mugu.
