These faint objects above, imaged in infrared by NASA's Spitzer space telescope, may just be the very first objects created in the universe.
"These objects would have been tremendously bright," Alexander "Sasha" Kashlinsky of NASA's Goddard Space Flight Center in Greenbelt, Md., said in a statement Thursday (June 7). "We can't yet directly rule out mysterious sources for this light that could be coming from our nearby universe, but it is now becoming increasingly likely that we are catching a glimpse of an ancient epoch."
Spitzer spotted these ancient structures after observing two patches of sky for more than 400 hours each. The telescope sees in infrared light, the long-wavelength range of the electromagnetic spectrum that's less energetic than optical light.
