There’s nothing quite like the first time. 🌟

No one knows for sure when the first stars in our universe burst to life — but Spitzer Space Telescope has offered insight about the Epoch of Reionization, a major cosmic event that transformed the universe from being mostly opaque to the brilliant starscape we see today.
This deep-field view of the sky taken by @NASAHubble and Spitzer space telescopes is dominated by galaxies — including some very faint, very distant ones.
