The Hubble Space Telescope has peered back to a chaotic time 13. 2 billion years ago when never-before-seen galaxies were tiny, bright blue and full of stars bursting to life all over the place.
Thanks to some complex physics tricks, NASA’s aging telescope is just starting to see the universe at its infancy in living color and detail.
Images released by NASA on Tuesday show galaxies that are 20 times fainter than those pictured before. They are from a new campaign to have the 23-year-old Hubble gaze much earlier and farther away than it was designed to see.
“I like to call it cosmic dawn,” Hubble astronomer Jennifer Lotz said at the American Astronomical Society convention in Washington. “It’s when the lights are coming on.”

Astronomers have seen a distant galaxy that blasts away material with two trillion times the energy the sun emits — the biggest such eruption ever seen. That ejection of matter could answer an important question about the universe: why are the black holes in the centers of galaxies so light?
Computer models of the early universe usually produce a virtual cosmos that looks like ours except for one thing. The ratio of the mass of black holes in galaxy centers to the rest of the matter in galaxies is larger in the simulations than in the real universe.

The Hubble Space Telescope launched on April 24, 1990, ushering in a new era in space exploration.
From its low-earth orbit, the telescope can take pictures without interference from the planet’s atmosphere, snapping photographs in visible light, ultraviolet and near-infrared wavelengths.
