NASA's Chandra X-ray observatory has found a mysterious X-ray signal that astronomers are speculating could signal the presence of dark matter some 240 million light years away from Earth.

A leading theory, NASA reports, is that the X-rays are a result of decaying "sterile neutrinos," which are particles that could potentially produce dark matter. Astronomers believe dark matter accounts for 85 percent of all matter in the universe, but dark matter does not emit or absorb light as does the "normal" matter in planets, stars, and galaxies, so its detection is much more difficult.

NASA notes that normal matter may also have created the emission line, which appeared in the Perseus galaxy cluster, but astronomers are excited at the prospect that the sterile neutrinos may be at play. The scientists' next step will be combining the data with results from other missions to see if the same X-ray signal appears in other galaxy clusters. Thus far, the line has also been found in 73 other galaxy clusters using NASA's XMM-Newton.

"We know that the dark matter explanation is a long shot, but the pay-off would be huge if we're right," Esra Bulbul, leader of the study and a fellow at the Harvard-Smithsonian Center for Astrophysics, told NASA. "We're going to keep testing this interpretation and see where it takes us."

Astronomers have yet to determine what caused the emission, but for now, check out an image of the signal below. --Meghan DeMaria

As the Syrian government works to cut off Aleppo's rebel supply route from Turkey, foreign intervention is not welcome, Foreign Minister Walid-al-Moallem warned Saturday, The Associated Press reports.

"Any ground intervention in Syria without the consent of the Syrian government will be considered an aggression that should be resisted by every Syrian citizen," he said. "I regret to say that they will return home in wooden coffins."

Saudi Arabia recently said it would sent troops as part of a U.S.-led coalition to fight Islamic State extremists, which controls parts of Syria. The United Nations suspended peace talks Wednesday as conflict near Aleppo ramped up. Julie Kliegman

At least 13 people died and hundreds more were injured in a 6.4-magnitude earthquake that struck Taiwan on Saturday, The Associated Press reports.

Rescuers saved hundreds of people from buildings and were still trying to reach others. Dozens of people are reportedly unaccounted for, CNN reports.

The high-rise residential building that collapsed in the 4 a.m. quake included a care center for newborn babies. One 10-day-old baby was reportedly among the dead. Julie Kliegman

On Sunday, the Carolina Panthers will meet the Denver Broncos in Super Bowl 50. But aside from the snacks and the commercials that star puppies, I'm pretty lukewarm about the spectacle.

And then I go and find a photo like this, from the very first Super Bowl in 1967, when the Green Bay Packers trounced the Kansas City Chiefs, and I lament my indifference to the sport.

Just look at their utter jubilation! The man in the middle, who's wearing what looks to be an ascot (imagine a time when football fans wore ties and ascots to the game!), waving his arms around like he just don't care, is having a near-religious experience. It's inspiring and I'm jealous. Lauren Hansen

An Indiana lawmaker is refusing to back civil rights protections for gays and lesbians because there are no similar laws protecting "fat white people." State Rep. Woody Burton called homosexuality "a behavioral thing," like overeating, and argued, "If I pass a law that says transgenders and homosexuals are covered under the civil rights laws, does it say anywhere that fat white people are covered?"

Twitter revealed Friday that it has deleted 125,000 accounts threatening or promoting terrorism since mid-2015, CNBC reports. The Brookings Institution estimated last year that there were at least 46,000 such accounts in existence; Twitter's numbers indicate that ISIS and other terrorist groups have either upped their presence on social media, or Twitter has become better at targeting terrorist accounts.

Spam-fighting technology flags posts by potential terrorists, which are then reviewed by humans, The Associated Press reports. Prior to Friday, Twitter had not revealed the scale to which terrorists were active on Twitter. Jeva Lange

At the price it sells for, this little chocolate ball "better cure PMS, heartbreak, and file our income taxes," said Dominique Haikel at E! Online. For years now, La Madeline au Truffle ($250) from Connecticut-based chocolatier Fritz Knipschildt has reigned as the most extravagant confection in the world. Each one is made to order to get the most of its seven-day shelf life. Dark chocolate dusted in cocoa powder encases a rare mushroom — a Périgord truffle — that's been smothered in a chocolate ganache infused with truffle oil. The whole thing weighs just 1.9 oz, but comes resting on a bed of sugar pearls in a pretty silver box. The Week Staff

The Vatican announced Friday that Pope Francis and the head of the Russian Orthodox Church, Patriarch Kirill, will meet in Cuba next Friday, marking the first such meeting between a pope and a Russian patriarch in history. The Eastern Orthodox and Western factions of Christianity split nearly 1,000 years ago in 1054's Great Schism over issues such as papal authority and have remained "formally estranged" ever since, The Washington Post reports.

The private, two-hour meeting will take place at José Martí International Airport in Havana. It's seen as the most significant effort ever made to repair relations. Becca Stanek
