Abell2744 Y1: One Of The Most Distant Galaxies Spotted
MessageToEagle.com – One of the most distant galaxies have been spotted by Spitzer and Hubble and thus, our telescopes looked back to the craddle of our universe when it was only about 650 million years old (our universe is 13.8 billion years old).
The galaxy, known as Abell2744 Y1, is about 30 times smaller than our Milky Way galaxy and is producing about 10 times more stars, as is typical for galaxies in our young universe.
The discovery comes from the Frontier Fields program, which is pushing the limits of how far back we can see into the distant universe using NASA’s multi-wavelength suite of Great Observatories.

Spitzer sees infrared light, Hubble sees visible and shorter-wavelength infrared light, and NASA’s Chandra X-ray Observatory sees X-rays.
The telescopes are getting a boost from natural lenses: they peer through clusters of galaxies, where gravity magnifies the light of more distant galaxies. Read rest of the story here:
