Hubble celebrates 22nd anniversary in orbit with stunning mosaic space image of several million stars 650 light-years across

an image captured by the Hubble Space Telescope shows young stars in the heart of the Tarantula nebula, named so by early astronomers because its glowing filaments resemble spider legs

Happy Birthday, Hubble! A Stunning New Picture for a Special Day
Things didn't look too bright for the Hubble Space Telescope when it first went into orbit back in 1989: the $1.5 billion eye on the universe had gone into space with its light-gathering mirror polished to perfection, which was very good, but the mirror was also the wrong shape — which was very bad. It wasn't until 1993 that the shuttle Endeavour went aloft with a set of corrective optics — essentially space telescope glasses — that sharpened Hubble's blurry vision and allowed it to begin conducting the stargazing work it was built to do. Since that exercise in orbital optometry, Hubble has been sending home one astonishing photo after another — and one scientific breakthrough after another too.

This week the telescope celebrates its 22nd birthday in orbit, and the folks at the Space Telescope Science Institute (STScI) are handing out party favors in the form of a dazzling new space image. Even by Hubble standards, it's pretty extraordinary.

The photo — actually a mosaic assembled from 30 separate images — captures an enormous swath of space that's home to the biggest population of giant stars ever found. It's a swirling cloud of gas and dust known as the Tarantula nebula, and despite its forbidding name, it does some very creative work — serving as a nursery for entirely new stars. At the heart of the nebula is a stellar cluster known as NGC 2070, less than 3 million years old, containing about half a million young stars — some of which weigh in at as much as 100 times the mass of our own sun. The ultraviolet light spewing from these intensely hot bodies has carved out gaps in the surrounding cloud, much as the very first stars in the universe cleared gaps in the fog of gas that condensed out of the Big Bang. Not only that: the shock waves created by the barrage of ultraviolet are probably triggering yet another round of star formation that has barely begun.

Hubble's portrait of the nebula is remarkable for more than just the science: even after the telescope was repaired in 1993, it couldn't have captured such an image. That's because the two instruments that did the photographing — snapping 15 pictures each — weren't even on the original Hubble. Known as the Advanced Camera for Surveys and the Wide Field Camera 3, they were installed by spacewalking astronauts during shuttle missions in 2002 and 2009, respectively.

What makes the composite portrait all the more impressive is that the Tarantula nebula is nearly 170,000 light-years from Earth. It's not even part of our own galaxy; instead it lies in the dwarf galaxy known as the Large Magellanic Cloud. At this distance, most telescopes could pick out only a few individual stars; the Hubble, flying high above the blurring caused by Earth's atmosphere, can resolve thousands.

I am afraid that our eyes are bigger than our stomachs, and that we have more curiosity than understanding. We grasp at everything, but catch nothing except wind.
