This absolutely gorgeous shot is the most detailed ever taken of what HubbleSite describes as the "largest stellar nursery in our local galactic neighbourhood". Get ready to pick your jaw up off your lap.
In the words of experts who understand more about this stuff than "OMG so pretty!":
The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way. There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years.
This shot (full, massive size can be found here) were taken between October 20-27 of this year by Hubble's Wide Field Camera 3. The blue lights are from the hottest, biggest stars, while the green is oxygen and the red is hydrogen. Whoa, you guys. Whoa.
