Wilco has announced it'll release the band's 11th studio album later this year. Drawing its title from the poetry of Friedrich Schiller — and Beethoven's Ninth symphony — Wilco's Ode to Joy will feature what frontman Jeff Tweedy calls "really big, big folk songs," including the album's first single, "Love is Everywhere (Beware)."

The Smithsonian National Air and Space Museum will celebrate the 50th anniversary of the Apollo 11 moon landing with a life-size projection of the Saturn V rocket on the Washington Monument on Tuesday, Wednesday and Thursday.

Fifty years ago, two astronauts became the first humans to set foot on the moon. Like many explorers, they documented their accomplishment in photographs. The images they took are some of the most enduring of the 20th century, traveling from Life magazine to MTV to Twitter.

For most of us, the photos brought back by Apollo 11 are iconic and a little difficult to comprehend. But for astronauts, they represent something more: hours of training, risks taken and the many people on the ground who worked to make the journey possible.

Brian Lapointe, a research professor at Florida Atlantic University's Harbor Branch Oceanographic Institute, has spent his career studying corals at the Looe Key Reef, in a National Marine Sanctuary in the Florida Keys.

Over that time, he's witnessed an alarming trend. In the past 20 years, half of Florida corals have died off.

Look at a picture of the Apollo 11 launch and you'll probably notice the rocket's pointed tip and the fire coming from the five giant engines in the first stage of the 36-story-tall Saturn V rocket.

What you might miss is arguably the most important part of the entire thing: the command module.

In the past year or so, scientists have discovered more evidence for liquid water under the surface of Mars. They've found complex organic compounds — the building blocks of life. And they've found that methane levels in Mars' atmosphere vary with the seasons.

"Each of these things adds up to say that the probability of finding life on a world that's not our own is going up," says NASA Administrator Jim Bridenstine. "And Mars, I think, is that best opportunity in our own solar system to find life on another world."

When Bethany Hamilton was 13 years old she lost her arm to a shark while surfing in Hawaii. That event catapulted her into the public spotlight, from talk shows to a Hollywood movie based on her life.

Not only did Hamilton return to the water, but she went on to ride some of the world's biggest waves. Her story is told in the new documentary Bethany Hamilton: Unstoppable.
