Hubble and baby galaxies
Refurbishing the Hubble Space Telescope has done wonders to its resolution... The installation of the new Wide Field Camera 3 (WFC3) has given the Hubble the capability to detect near infrared energy from the farthest galaxies/stars. Why near-infrared? Because light from distant galaxies get stretched as the universe expands (thus converting the ultraviolet to visible spectra into near-infrared).
Just take a look at this picture, which was released by the Hubble today:
The reddest and faintest objects in this picture are galaxies that were formed 600 million years after the Big Bang. Most of the objects observed in this 173,000-second exposure photo were not detected when Hubble's Ultra Deep Field camera was in use.
