Galaxy MACS0647-JD - Thanks to Hubble Telescope!!

MACS0647-JD , a newly discovered distant galaxy, was observed 420 million years after the Big Bang. It took almost 13.3 billion years for its light to reach our earth!!!

This has been possible because of the power of NASA's Hubble , Spitzer space telescope and natural "zoom lenses" in space .

Astronomers says that MACS0647-JD is only a tiny fraction of the size of our Milky-way galaxy!
The Light from MACS0647-JD  came around multiple path of large galaxy cluster MACS J0647+7015. Using a phenomenon called "gravitational lensing" and also with the help of Hubble telescope ,the CLASH research team (An international group led by Marc Postman of the Space Telescope Science Institute in Baltimore, Md., ) observed three images of  MACS0647-JD. This cluster  MACS J0647+7015's gravity helped a lot by boosting up(magnified) the light from the galaxy ,which resulted the image to appear approximately eight,seven and two times brighter .

It has been observed that the galaxy is almost 600 light years wide, which is so small(when compared to other galaxy)  so,the object is assumed to be in its 1st step of forming an entire galaxy.
The total mass of stars in this galaxy is approximately calculated to be equal to 100 million suns i.e about
 0.1 %  to 1% the mass of our milky way galaxy.

This is another remarkable day for Astronomers :)
The team hope to use Hubble to search many other dwarf galaxies which is in their early stage of development so that they could have provided energy to burn the fog of hydrogen that spread over the universe. And this process is called "Re-ionization",which will ultimately make the universe transparent to light!!!!

Invasion continues!!! :)
