By using the Hubble and Spitzer of NASA's telescope, astronomers recorded a new record by discovering the most distant galaxies in the universe. Galaxy that looks like a small lump was offered the opportunity to take a peek back in time when the universe was only three per cent and is now 13.7 billion years old.

New galaxy named MACS0647-JD is thought to have formed 420 million years after the big bang (big bang), which in theory is the early formation of the universe. The light traveled 11.3 billion years to reach Earth.
The CLuster tensing And Supernova survey with Hubble (CLASH), an international group led by Marc Postman of the Space Telescope Science Institute in Baltimore, USA, directing cosmic telescope into a giant cluster of galaxies to obtain greater than a distant galaxy. In the eight-million-year journey, the light of MACS0647-JD walked around through many ways around the massive galaxies called MACS J0647+7015.
CLASH research team were able to observe three-JD MACS0647 picture magnified by gravitational lensing using the Hubble telescope. "This cluster does what no manmade telescope can do. Without the magnification, it would require a Herculean effort to observe this galaxy," said Postman in NASA's official website.
MACS0647-JD is very small, just like a very small fraction of the Milky Way that is likely to come from the first stage of the formation of larger galaxies. The analysis shows, these galaxies width of less than 600 light years away, a smaller similar type of galaxy about 2,000 light-years wide.
For comparison, the Large Magellanic, a small galaxy that accompanies the Milky Way, has a width of 14,000 light years and the Milky Way is 150,000 light-years wide. *** [SRI | PIKIRAN RAKYAT 22112012]
