See All 46 Billion Pixels of this Record-Breaking Milky Way Photo

Nothing beats gazing up at a clear night sky, but astronomers at Germany's Ruhr-Universität Bochum have produced the next best thing—and it’s absolutely stunning.

The team has created the largest astronomical image ever, and it features the Milky Way. Containing 46 billion pixels, the 194-gigabyte file is so large that it must be viewed through the university’s online tool, where you can zip around to different regions and even search for particular celestial landmarks.

The image is the culmination of five years of observations focused on the search for objects with variable brightness. Such objects with changing luminosity are valuable tools for astronomers, who can use them to find planets, stars, or other bodies. In their research, the team found more than 50,000 never-before-recorded objects with variable brightness.

Because the Milky Way is so expansive (and yet on a universal scale so very, very small), researchers split up the sky into 286 regions to observe. Those regions were individually photographed over time and then compiled into a complete picture of the galaxy. The photos were taken from an observatory in Chile’s Atacama Desert.

History
When Chuck Yeager Tweeted Details About His Historic, Sound Barrier-Breaking Flight

Seventy years ago today—on October 14, 1947—Charles Elwood Yeager became the first person to travel faster than the speed of sound. The Air Force pilot broke the sound barrier in an experimental X-1 rocket plane (nicknamed “Glamorous Glennis”) over a California dry lake at an altitude of 25,000 feet.

In 2015, the nonagenarian posted a few details on Twitter surrounding the anniversary of the achievement, giving amazing insight into the history-making flight.

Caroline Herschel (1750-1848) was a German woman who made great contributions to science and astronomy. 

1. SHE WAS THE FIRST WOMAN TO DISCOVER A COMET.

Herschel spotted the comet (called 35P/Herschel-Rigollet) in December of 1788. Because its orbital period is 155 years, 35P/Herschel-Rigollet will next be visible to humans in the year 2092.

2. SHE INITIALLY WORKED AS A HOUSEKEEPER.

In her early twenties, Herschel moved from Germany to England to be a singer. Her brother William (the astronomer who discovered the planet Uranus and infrared radiation) gave her singing lessons, and she was his housekeeper. She later became his assistant, grinding and polishing the mirrors for his telescopes.

3. BUT SHE LATER TURNED HER REAL PASSION INTO A PAYING GIG.

Herschel was the first female scientist to ever be paid for her work. Starting in 1787, King George III paid her £50 per year to reward her for her scientific discoveries.

4. SHE WAS TECHNICALLY A LITTLE PERSON.

Herschel was only 4 feet 3 inches tall—her growth was stunted due to typhus when she was 10 years old.

5. SHE BROKE BARRIERS, EARNING RESPECT FROM THE HERETOFORE MALE-ONLY SCIENTIFIC COMMUNITY.

Herschel was the first woman to receive a Gold Medal from London’s Royal Astronomical Society, in 1828. The second woman to receive one was well over 150 years later, in 1996.

6. SHE CHEATED AT MATH ... KIND OF.

Because Herschel was female and thus wasn’t allowed to learn math as a child, she used a cheat sheet with the multiplication tables on it when she was working.

7. EARTH'S MOON HONORS HER LEGACY.

A crater on the moon is named in honor of Herschel—it’s called C. Herschel. The small crater is located on the west side of Mare Imbrium, one of the moon's large rocky plains.

8. SHE GARNERED AWARDS WELL INTO HER NINETIES.

For her 96th birthday, Prussian King Frederick William IV authorized that Herschel receive an award: the Gold Medal for Science.
