This was culled from an analysis of the deepest Hubble Space Telescope sky survey, CANDELS (Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey). Previously, studies using Caltech's CIBER (the Cosmic Infrared Background Experiment) rocket-borne instrument and NASA's Spitzer Space Telescope images confirmed the presence of "intra-halo light" from stars distributed outside of galaxies.
The Hubble data found a new component in the infrared background in addition to intra-halo light — the collective glow of entire galaxies that formed first in the universe. UCI's Asantha Cooray believes that these early galaxies are very different from the well-defined spiral and disk-shaped galaxies seen in the present-day universe. They were more diffuse and populated by giant stars.
This discovery paves the way for to see these very faint galaxies individually, after its launch in 2018.

This week's hangout will feature the latest new Hubble Heritage image celebrating 25 years of discovery with the Hubble Space Telescope. We'll show the image and there's even an animation! All this happens this Thursday! Please join us and bring your comments and questions.
Please join +Tony Darnell, Dr. +Carol Christian and +Scott Lewis as they discuss this new image with +Zolt Levay and Greg Bacon of the STScI Hubble Heritage Team.

Collecting these yearly images – essentially the planetary version of annual school picture days for children – will help current and future scientists see how these giant worlds change over time. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry.
Already, these new images have revealed new features of the Jovian giant never before seen.
Please join and Dr. as they discuss these exciting new images with the team of astronomers who made them.

Nearly 400 years after Galileo first observed the heavens through a telescope, we continue to seek answers to age-old questions about the universe. And while the technology has evolved over the centuries, the inquiry remains essentially the same: What's out there, where did it come from, and what does it mean?
At the Space Telescope Science Institute (STScI), we're working hard to study and explain the once-unimaginable celestial phenomena now made visible by the Hubble Space Telescope's cutting-edge technology.
