Good riddance, 2016.

It was a year defined by political turmoil, heartbreaking losses, monumental disappointments and near-global discord. Our phones exploded, the Zika virus spread and Ryan Lochte may or may not have vandalized a bathroom in Rio.

Will 2017 offer something better? It’s worth looking back through the debris of the last year to remember that it wasn’t all bad.

As you prepare for another trip around the Sun, enjoy our list of undeniably good things that happened over the course of this objectively wretched year.

Physicists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) did a favor for Albert Einstein by confirming the existence of gravitational waves. Einstein predicted these distortions in the fabric of spacetime in 1916 with his general theory of relativity. But direct evidence had eluded scientists until the $1 billion LIGO experiment caught hints of gravity waves made by the collision of two massive black holes 1.3 billion years ago.

For the first time in nearly 1,000 years, Pope Francis met with Patriarch Kirill of the Eastern Orthodox Church. It marks the first encounter between the leaders of Christianity’s two largest churches since 1054, when the Eastern Orthodoxy split with Rome.

“Finally! We are brothers,” the pope said as he embraced Kirill after their two-hour meeting in Cuba’s Havana airport in February.

Global tiger numbers are up for the first time in a century, and conservation experts credit this improvement with better coordinated efforts among nations that serve as natural habitats for tigers. An estimated 3,890 tigers are alive today, up from 2010 when the count was about 3,200 worldwide.

Harriet Tubman, a former slave and African-American abolitionist who helped hundreds of enslaved people escape to freedom on the Underground Railroad, will replace President Andrew Jackson on the front of $20 bills, the U.S. Treasury Department announced in April. A century ago, first lady Martha Washington’s portrait was the last image of an American woman to appear on U.S. currency.

The teenage birth rate hit an all-time low in the U.S., according to the Centers for Disease Control and Prevention. And over the last decade, the most significant drops were in non-white communities. Experts attribute these improvements to a decline in teen sexual activity and an increase in contraception use.

We feared the games would be a catastrophe in Rio, but Brazil hosted one of the most memorable and exciting Olympics in recent history. And to top if all off, team USA sported several golden Olympic moments this year. Simone Biles led The Final Five to gold in gymnastics. Katie Ledecky broke multiple world records in the pool, including her own, while Michael Phelps broke a 2,000-year-old Olympic record. And don’t forget Simone Manuel’s reaction after her historic win as the first black woman to take gold in an individual swimming event.

The National Park Service turned 100 years old on August 25, 2016. Yellowstone National Park in Wyoming was first and since then 58 have followed expanding upon America’s “best idea.” But the system itself oversees far more than that. All told there are more than 400 parks, battlefields, historic sites, monuments, preserves, parkways and reserves encompassing 84 million acres. More than 275 million people visit them each year.

Measles were eliminated from the Americas in 2016. The World Health Organization made the proclamation in September after a two decade-long vaccination effort. It’s the first region in the world to completely eliminate the viral disease that can cause severe health problems, including pneumonia, blindness, brain swelling and in some cases, death.

The world’s largest marine zone, a 600,000-square-mile swath of ocean, was established in Antarctica’s Ross Sea this fall. This comes after an agreement was reached by 24 nations and the European Union in late October. Most commercial fishing will be banned in the newly protected zone, with the exclusion of designated research zones, where scientists can catch limited samples of fish and krill.

“It’s the first time that countries around the world are coming together to agree not to take fish or other species out of the water, but to leave them in, and to leave them in for a good long period of time,” Karen Sack, managing director of the conservation organization Ocean Unite, told the NewsHour’s William Brangham in an Oct. 28 interview.

The nation’s jobless rate sank to 4.6 percent, a level not seen since August 2007 and before the onset of the Great Recession when unemployment picked at 10 percent in October 2010, according to monthly figures from the Bureau of Labor Statistics.

The Chicago Cubs won. No longer lovable losers. No more cursed goat. No more “wait till next year.” We all watched long-suffering fan Bill Murray cry. And yet, even when the famous “W” flags waved in and around Wrigley Field after the historic win, it wasn’t a complete shedding of heartbreak. In fact, ESPN’s Wright Thompson observed a “palpable sadness” amid all the joy. “Nobody could really be sure how’d they’d feel when it all ended, whether they’d be full of joy, or grief, or both,” he wrote. It’s hard being a Cubs fan.

When the Colombian government and FARC rebels agreed to end more than 50 years of civil war last summer, people celebrated in the streets. But the public ended up narrowly rejecting the initial deal in an Oct. 2 referendum. So negotiators went back to the drawing board, made some changes to pacify those who thought the rebels weren’t being punished enough for past atrocities. Colombian President Juan Manuel Santos told PBS NewsHour co-anchor Judy Woodruff that the peace agreement “will open up opportunities that Colombia had never imagined.”

The nation’s high school graduation rate rose to an all-time high this year with 83 percent of students earning their diplomas, according to the Department of Education. That marked a significant improvement since 1999 when high schools reported a 71 percent graduation rate.
