Esa/hubble: Hubble Sees Oldest Galaxies Yet

Curated by ACT

In 2004, Hubble created the deepest visible-light image of the Universe and now, with its brand-new camera, Hubble is seeing even farther in the same region. Hubble's newly installed Wide Field Camera 3 (WFC3) collects light from near-infrared wavelengths and therefore looks even deeper, because the light from hot young stars in very distant galaxies is stretched out of the ultraviolet and visible regions of the spectrum into near-infrared wavelengths by the expansion of the Universe. The new deep view also provides insights into how galaxies grew in their formative years early in the Universe's history.
