NASA's Cassini spacecraft has discovered a "mysterious feature" on Saturn's moon Titan. Scientists are working to determine, what, exactly, this feature might be.
NASA reports that the feature is roughly 100 square miles, and it lies in Ligeia Mare, one of Titan's hydrocarbon seas. Cassini's radar has observed the feature twice, but its appearance changed between the two sightings. Scientists suspect the feature's change in appearance could be the result of Titan's changing seasons, which Cassini's current extended mission will monitor.
The feature's first sighting was in July 2013, and the radar images depicted a bright spot, which stood out from the dark sea. Scientists were "perplexed" when the feature couldn't be located with follow-up radar experiments, but they found it again on August 21, 2014.

Though the scientists aren't sure what the feature is, NASA reports that they are "confident" the feature is not a "flaw in their data." Some of their current explanations for the feature include "surface waves, rising bubbles, floating solids, solids suspended just below the surface, or perhaps something more exotic."
Titan's hydrocarbon lakes have long been a source of curiosity for scientists who speculate that life may be able to survive on the moon's surface. "But if life exists on Titan, it would be very different than life on Earth, which is intimately tied to liquid water," Space.com notes.
"Science loves a mystery, and with this enigmatic feature, we have a thrilling example of ongoing change on Titan," Stephen Wall, the deputy team lead of Cassini's radar team, said in a statement. "We're hopeful that we'll be able to continue watching the changes unfold and gain insights about what's going on in that alien sea." Meghan DeMaria
On Wednesday's Jimmy Kimmel Live, Kimmel asked Donald Trump a question from Bernie Sanders — a Trump-Sanders debate may arise out of it, seriously — and on Thursday's show, Kimmel asked Sanders a Trump question: "Dear Crazy Bernie, will you run [as] a third-party communist against Hillary, or are you a coward and a loser?" That wasn't the actual question, but what Trump really proposed was essentialy the same. "Bernie, you have been treated very unfairly," Trump began. "Will you run as an independent when Debbie Wasserman-Schultz and the Democratic Party bosses steal this nomination away from you?"
"Well, I think there's a little self-service there for Donald Trump," Sanders said. And then he poured on the sarcasm, finally ending with his final answer: "Tell him what I hope will happen is that, in fact, I will run against him as the Democratic nominee for president of the United States, and if I do, we're going to beat him, and beat him bad. You can tell him that." "I don't think I'll see him again," Kimmel replied. But if the debate really happens — and I'd say it won't, but who knows with this election? — Sanders can tell Trump himself. Peter Weber
In a speech at the Hiroshima Peace Memorial Park, alongside Japanese Prime Minister Shinzo Abe, President Obama called for an end to nuclear weapons. On June 6, 1945, Obama said, "death fell from the sky and the world was changed." When the U.S. dropped an atomic bomb on Hiroshima, and then Nagasaki, killing about 210,000 people and effectively ending World War II, the bomb "demonstrated that mankind possessed the means to destroy itself."
"We stand here in the middle of this city and force ourselves to imagine the moment the bomb fell," Obama said, "We listen to a silent cry." He did not apologize, but said the memory of Hiroshima "must never fade." He ended his speech with a call for "a future in which Hiroshima and Nagasaki are not known as the dawn of atomic warfare, but as the start of our own moral awakening."

Obama is the first sitting U.S. president to visit Hiroshima. Before speaking, Obama laid a wreath at the monument, and afterward he met with survivors of the bombing. Obama also signed the guest book, and this is what he wrote: "We have known the agony of war. Let us now find the courage, together, to spread peace, and pursue a world without nuclear weapons."

On Friday, President Obama landed in Hiroshima, making him the first sitting U.S. president to visit the city destroyed by a U.S. atomic bomb at the end of World War II. Obama has said he won't apologize for the bombing, which killed 100,000 people, mostly civilians, but on Friday he laid a wreath at the Hiroshima Peace Memorial Park and also visited the more controversial museum, which mostly portrays Japan as a victim. Security is tight at the memorial park, but hundreds of people are lined up along Peace Boulevard, waving for Obama, The New York Times reports, including bombing survivors, a Buddhist monk, and families and office workers.
"Even if all he does is come here, that is enough," said Jitsuo Mizuta, 84, who survived the Hiroshima bombing. "I am so happy. I don't need any apology or anything." Peter Weber
On Thursday's Late Show, Stephen Colbert had a little announcement: "Just today, Donald Trump received his 1,237th delegate, clinching the Republican nomination." He let that sink in a bit. "So, that's it," he said. "It's official. The die is cast. Trump's the nominee." Colbert laid down on the floor. Then he explained what put Trump over the top: really unenthusiastic Republican delegates agreeing to back the now-really-presumptive nominee. Seriously, the quote he read from a Pennsylvania delegate is hilariously cold — and Colbert reluctantly got off the floor to offer some suggestions to spice it up.
"But wait, there's more," Colbert said, bringing up the tentative debate between Trump and Bernie Sanders. The audience cheered. "I don't know why you're applauding," he said. "That's going to be two angry New Yorkers shouting at each other. It'll be like the whole country is trapped in a subway car." Colbert also noted that Trump's condition is raising somewhere near $15 million for a charity — and Colbert had a guess at the one Trump would choose. Watch below. Peter Weber
On Wednesday's Jimmy Kimmel Live, Kimmel got Donald Trump to agree to a debate with Democratic contender Bernie Sanders. On Thursday's show, Kimmel asked Sanders if he saw what he did for the Vermont senator. "You made it possible for us to have a very interesting debate about two guys who look at the world very, very differently," Sanders said. The Trump camp has gone back and forth on the debate, asking for payment that would go toward some charity. But if it happens, "that would be some debate," Kimmel said. "I mean, I really think it might be one of the highest-rated events in televisions history." Sanders nodded and said "the goal would be to have it in some big stadium here in California"
Kimmel noted that Hillary Clinton had decided not to debate Sanders, and asked him if he understood the political logic of Clinton's decision. Sanders said no. Then Kimmel played a clip of Clinton telling CNN's Chris Cuomo that she was going to be the nominee, and Sanders got a little animated, saying, "Just a pinch of arrogance there, I think." He acknowledged that he has to win really big in California and the other five states voting June 7 to catch Clinton in pledged delegates, then criticized superdelegates and pointed to polls showing him doing better against Trump than Clinton.

On Thursday night, the House voted down an energy and water spending bill, 305-112, after Republicans held a private meeting to air grievances about an amendment approved Wednesday night to protect LGBT employees of federal contractors. That amendment passed, with 43 Republicans joining 180 Democrats, but only six Democrats voted to support the overall bill on Thursday. House Speaker Paul Ryan (R) blamed Democrats for thwarting the annual spending bill, telling reporters the minority party was "looking to sabotage the appropriations process."
Democrats noted that Republicans had also added objectionable amendments to the bill, including ones on Iran's nuclear program, LGBT students, and blocking the Obama administration from punishing North Carolina for its anti-transgender bathroom bill. The embarrassing failure of the energy bill points to conflicting goals of Ryan's speakership: returning to the normal order of passing individual spending bills, and allowing House members to propose amendments on the House floor.
Rep. Sean Maloney (D-N.Y.) said he would continue offering his LGBT anti-discrimination measure, which evidently has majority support in the House. Sen. John Cornyn (R-Texas) warned that the failure to pass the energy appropriation bill points toward another standoff on spending, or even a government shutdown, in the fall. "It's a terrible way to govern," he told The New York Times. Peter Weber
"Hillary Clinton's email scandal is the story that just won't die," Seth Meyers said on Thursday's Late Night — or to use the preferred cable news analogy, Wednesday's State Department inspector general's report is just the latest "drip, drip, drip" in the ongoing investigation. "You know, if you're wondering why so many Democrats are attracted to Bernie Sanders, this is kind of why," Meyers said. "Bernie doesn't have any drip-drip-drips — which for a 74-year-old man, is pretty remarkable."
Clinton never sought permission to use a private email server, the report said, and failed to turn over all department-related emails before she left office — a process that would have involved printing out and filing each email, Meyers noted. "Ugh, the only way this scandal could be more boring is if Wolf Blitzer talked about it. Here, I'll prove it." But he dug up some interesting tidbits from the IG report, like that Clinton's emails were going to the spam folders of State Department employees. Will this change anything? "For Hillary supporters, yesterday's report probably won't seem too scandalous, whereas it's a bombshell to Hillary detractors" who already see her as untrustworthy, Meyers said. And if you get to the point about U.S. nuclear weapons being run using 1970s-era floppy disks, well, there's a reason for that. You can get up to speed on the Clinton emails below. Peter Weber
