It took two years — and 21,400 shots — to capture an astonishing view of your spiraled galactic home, the Milky Way.
On Jan. 18, astronomers released a "gargantuan" survey of the Milky Way as part of an ambitious project called the "Dark Energy Camera Plane Survey." They captured this view using an instrument called the Dark Energy Camera at the Cerro Tololo Inter-American Observatory, perched at 7,200 feet of elevation in Chile. The camera is mounted to a large telescope that spans over 13 feet wide; ultimately it snapped images of a whopping 3.32 billion objects, most of which are stars.

"This is quite a technical feat. Imagine a group photo of over three billion people and every single individual is recognizable!" Debra Fischer, division director of Astronomical Sciences at National Science Foundation, said in a statement. "Astronomers will be poring over this detailed portrait of more than three billion stars in the Milky Way for decades to come. This is a fantastic example of what partnerships across federal agencies can achieve."
SEE ALSO:Yes, there are 100 million rogue black holes wandering our galaxyThere are likely over 100 billion stars in the Milky Way, so this panorama is a deeply detailed sample of the galaxy as seen from Earth's Southern Hemisphere. Take a look:
The first image below:This is the panorama containing some 3.32 billion objects. "Most of the stars and dust in the Milky Way are located in its disk — the bright band stretching across this image — in which the spiral arms lie," explained National Science Foundation's NOIRLab, which runs big telescopes across the U.S. and elsewhere.
The bottom image: This is one part of the giant cosmic panorama above. "This image, which is brimming with stars and dark dust clouds, is a small extract — a mere pinprick — of the full Dark Energy Camera Plane Survey (DECaPS2) of the Milky Way," a NOIRLab press release explains.
And if you want more, there's more. You can view the entire survey, with the ability to zoom in and out, at the Legacy Survey Viewer website.
Our galaxy contains a plethora of stars, but it also contains giant regions of dust and gas. To peer through these obfuscating regions of space, astronomers captured wavelengths of light invisible to the naked eye that are called near-infrared wavelengths. This type of light, which travels in longer waves than visible light, can sneak or pass through space dust, revealing what lies beyond (the powerful James Webb Space Telescope views infrared light, too).

These new images capture an almost incalculable number of stars. Still, there's a lot we can't see out there, but we canimagine. Most stars have at least one planet, and many have diverse solar systems. That adds up to over a trillion exoplanetsin our Milky Way galaxyalone.
Some of these planets might rain gems. Some could be ocean worlds. Others could be rocky, Earth-sized planets. There's untold potential out there in our galaxy, a place teeming with brilliant stars.
