NASA's Cassini spacecraft is currently conducting a series of elaborate dives in which it repeatedly comes closer to Saturn than ever before. But during its slower periods, NASA is still using the craft's fantastic photography equipment to grab images of Saturn's nearby bodies, such as the moon Titan. The latest photo from the agency shows Titan in all its glory, complete with some very volatile cloud cover.
The new images, which were captured by Cassini on May 7th but not released immediately, show Titan in impressive detail, with long, feathery streaks of clouds obscuring portions of the landscape. But unlike the clouds we're used to here on Earth — which are made of extremely tiny water droplets or bits of crystalized ice — the clouds you see in the Titan photos are actually made of methane.
In addition to Titan's wealth of atmospheric methane, the planet also has vast lakes thought to be primarily made up of liquid ethane and methane, along with nitrogen. That's an extremely hostile combination, at least in terms of Earth-like life. However, NASA isn't ruling out the possibility that there may actually be methane-based life on the large moon, and even has some theories as to how it might survive.
According to NASA, these new photos were snapped at a distance of about 316,000 miles, which means that each pixel of the image equals roughly 2 miles. With that scale in mind, take a look at the dark splotches dotting the top of the image. Those are the huge methane-filled seas, which may or may not be home to huge, methane-filled whales.
By Ju-min Park and Jack Kim SEOUL (Reuters) - South Korea's new liberal President Moon Jae-in was sworn in on Wednesday and vowed to tackle immediately the difficult tasks of addressing North Korea's advancing nuclear ambitions and soothing tensions with the United States and China. Moon said in his first speech as president he would begin efforts to defuse security tensions on the Korean peninsula and negotiate with Washington and Beijing to ease a row over a U.S. missile defense system being deployed in the South. In a congratulatory phone call U.S. President Donald Trump agreed with Moon to cooperate on the North Korean nuclear issue and invited him to visit Washington, the South Korean presidential office said.
‘The rule of law has to prevail, not the rule of whim,’ said one former FBI agent. Donald Trump’s firing of the FBI director, James Comey, has left FBI agents shocked, angry and humiliated, with some former agents worried that the president has fundamentally compromised the bureau’s prized political neutrality. Bobby Chacon, a former FBI agent who served in Los Angeles and New York and retired in 2014, compared the abrupt firing to “a punch in the stomach to agents”.

By Ellen Francis BEIRUT (Reuters) - U.S.-backed Syrian militias said they fully seized the town of Tabqa and Syria's largest dam from Islamic State on Wednesday, a major objective as they prepare to launch an assault on Raqqa, the jihadists' biggest urban stronghold. The Syrian Democratic Forces (SDF), an alliance of Kurdish and Arab fighters, have been battling the militant group for weeks in Tabqa, some 40 km (25 miles) west of Raqqa, along the Euphrates River. With air strikes and special forces from the U.S.-led coalition, the SDF are advancing on Raqqa to ultimately take the city, which is also the Islamic State's base of operations in Syria.
