Astronomers have pushed Nasa’s Hubble Space Telescope to its limits by finding what they belive to be the most distant object ever seen in the universe. The observations provide the best insights yet into the birth of the first stars and galaxies and the evolution of the universe. Previous searches had found 47 galaxies at somewhat later times, when the universe was about 650 million years old.

The ever more distant proto galaxies will require the infrared vision of NASA’s James Webb Space  Telescope, which is the succesor to Hubble, and next-generation  ground-based telescopes, such at theb Giart Magellan Telesope. These new facilities, planned for later this decade, will provide confirming spectroscopic mesurements of the tremendous distance of the object being reported.

The proto galaxy is only  visible at the farthest infrared wavelengths observable  by Hubble. This means that the expansion of the universe has streched  its the light  farther that any other galaxy previously identified in the HUDF-IR, to the very limit of Hubble’s compatible.
