On a typical muggy midwestern August evening in 1977, astronomers at the Ohio State University’s Big Ear radio telescope got a big surprise. It was a signal so loud that it could only be described with one word: “wow!”

The internet and news media alike are abuzz with news about a radio buzz coming from Proxima Centauri, the nearest neighbor star to our sun a mere four and a quarter light-years away. That star happens to host a planet, called Proxima b (because we don’t have a cooler name for it yet), that sits in the habitable zone of its parent star. That means that the planet can potentially host liquid water, and where there’s liquid water there’s a chance for life.

Using a network of dead stars, astronomers get closer to seeing the background ripples of the universe.

With the evolution of reusable rockets through commercial companies such as SpaceX and Blue Origin, the cost of space exploration is decreasing. Learn more about today's "space race."

How did our solar system form? It's a pretty simple and straightforward question, but as with most things in science, simple and straightforward doesn't necessarily mean easy.

Gold had to come to Earth from somewhere, right? So why not outer space?

What we have is a cosmic whodunit. Venus, the second planet from the sun and considered by the more romantic types as "Earth's twin" and the avatar of love, is dead.

Since 1970, folks from around the world have gathered together to celebrate Earth Day, an appreciation for all the good stuff we’ve got here on the Earth – and a reminder to try not to mess it up. But what’s so special about the Earth, anyway?

In honor of Women's History Month, we're celebrating the achievements of women around the globe and throughout history. From the pages of The Explorers Journal, we're sharing stories from four women who broke boundaries in exploration, research, and science. In our final spotlight, meet the first American woman to walk in space and to reach the deepest known point in the ocean, Dr. Kathy Sullivan.

There will be 13 full moons in 2020. Take that how you will, but the full moon coming up this Halloween night is a hunter's blue moon. So what does that mean?

When we think of an ocean, we don't necessarily think of Pluto. If we can’t see the liquid water, why do astronomers think it’s there?

Blasting off into low Earth orbit may not be every traveler’s idea of a quiet getaway, but builders of the first space hotel are creating the ultimate exclusive destination. Voyager Station is scheduled to be operational by 2027 and will offer $5 million luxury suites, fine dining, and live shows to space tourists.

NASA’s James Webb Space Telescope captured new images of Jupiter revealing never-before-seen details of the planet.

Most people in the United States have lost access to the night sky. This may not be a surprise to you if you’re living in a major metropolitan area. Perhaps you can pick out some of the brightest stars or a few planets on a clear night, but that’s it. Participate in International Dark Sky Week, April 22–30; their mission is to reduce light pollution and bring better lighting to communities around the world so that all life can thrive.
