Time zone by time zone, the planet is saying goodbye to 2015.

The end of the year is still hours away in the U.S., but Australia has already hailed the new year with fireworks like those (see above) in Sydney Harbour.

In Japan's capital, balloons were released from Tokyo Tower.

A few highlights from other celebrations planned around the globe:

The University of Chicago is canceling all classes and other events on its main campus Monday over online threats of gun violence.

FBI counterterrorism officials alerted the school on Sunday, the university said in a statement. They warned of online threats from an "unknown individual" that specifically mentioned a location, the campus quad, and a time, 10 a.m.

Four civilian meteorologists who died during a U-boat attack in World War II posthumously received Purple Heart medals on Thursday.

Lester S. Fodor, George F. Kubach, Edward Weber and Luther H. Brady volunteered to serve on a Coast Guard ship in 1942. Kubach and Weber were 24; Fodor and Brady were 27.

The ship went on weather patrol in the North Atlantic, as NPR's Joe Palca reports for our Newscast division:

A new congressional task force dedicated to transgender equality was launched Tuesday. The group, announced by the Congressional LGBT Equality Caucus, was created in response to an "epidemic of violence against the transgender community," the caucus says.

The news comes during Trans Awareness Week, leading up to the Transgender Day of Remembrance on Friday.

Viola Davis made history at Sunday night's Emmy Awards when she won for best actress in a drama for How to Get Away With Murder: It's the first time that award has gone to a black woman.

When Davis' award was announced, Taraji P. Henson — nominated for the same award for her work on Empire — gave Davis a fierce hug and a one-woman standing ovation.

Kim Davis, the Kentucky county clerk who refused to issue marriage licenses to same-sex couples and was jailed on Thursday, is appealing the order that put her behind bars.

The Rowan County clerk had been ordered by a court to abide by the Supreme Court decision that made same-sex legal across the country. She refused, filing a series of appeals — and requesting a stay of the order from the Supreme Court, which was denied.

On Thursday, District Judge David Bunning found her in contempt of court and ordered she be held in custody until she complied with the order.

Wes Craven, the legendary horror director behind the A Nightmare on Elm Street and Scream franchises, has died at 76.

His verified Twitter account posted about his death Sunday evening. The Associated Press reports that he had brain cancer and died in his Los Angeles home, according to a statement from his family.

The U.S. team won the Women's World Cup soccer final 5-2 in a game that brought U.S. fans to their feet, reduced polished sportswriters to all-caps expressions of awe and rewrote FIFA records — and that was just in the first half.

The game began in spectacular fashion: In the first five minutes, captain Carli Lloyd scored two swift goals — the fastest two goals in FIFA history, according to the FIFA Women's World Cup Twitter account.

Just a few minutes later, Lauren Holiday brought the score up to 3-0.

It took nearly four decades, but a horse has once again attained the honor that some call the most difficult achievement in sports: American Pharoah, after winning the Kentucky Derby and the Preakness Stakes, ran to victory in the Belmont Stakes as well.

He's the first Triple Crown winner since 1978. With his win, a total of 12 horses have now achieved the feat.

American Pharoah took the lead early in the mile-and-a-half long race, with Frosted close on his tail. From there, the colt never gave up the front position.

American Pharoah is the king of the nation's horse races this month: in a driving rain, the Kentucky Derby winner took home top prize at the Preakness Stakes Saturday.

Ridden by Victor Espinoza, he left the other horses at Pimlico Race Course eating his mud; with an unofficial time of 1:58.46, he led by an impressive seven lengths.

If he can win the Belmont Stakes on June 6, he'll be the first Triple Crown winner since 1978.
