NASA Releases The Most Colorful Image Of The Universe To Date

And it's pretty spectacular.

It's easy to forget how impressive the Hubble Space Telescope is, but this newest image from NASA is among the most colorful deep space images released.


Because Earth's atmosphere filters ultraviolet light, in the past decade astronomers have lacked information ultraviolet provides. But this composite combines the full range of light available to Hubble. Made from 841 orbits of telescope viewing time, it contains approximately 10,000 galaxies.

When a star is born, it takes time before observable light reaches Earth. Before, astronomers used Hubble's near-infrared technology to watch births in galaxies far, far away, but only primitive stages were visible because of the significant amount of time needed for the light to travel.

That's where this image comes in: It provides the missing link in star formation — a gap of about 5 to 10 billion light-years, when most stars in the universe were born. Because the hottest, largest, and youngest stars emit ultraviolet light, astronomers have a new glimpse at which galaxies are forming stars — and where in the galaxies the stars are forming, exactly.
