One of life's building blocks could have originated in outer space. But if this experiment shows how these building blocks actually formed, how exactly did they get to Earth?

We watched last year as the NASA and SpaceX Crew-1 mission launched and docked to the International Space Station. After roughly ten weeks aboard the station, Crew-1 also known as Expedition 64 is now preparing to take their first spacewalk of the year.

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?

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.

Recently NASA’s DART mission succeeded in its primary goal, which was to slam a spacecraft face-first into an asteroid. For science. The intention of the mission was to test if we could actually redirect an asteroid and send it into a different orbit. But how and when will we know if it worked?

It sounds super-scary: something from outside the universe, a force so unimaginable, is pulling every single galaxy towards it. What monstrosity of cosmic physics could it be?

The eyes of much of the world have been looking up this week, gazing at Jupiter and Saturn as they dance tantalizingly close to each other.Many in the media and elsewhere have dubbed this planetary pair “the Christmas Star”, in reference to an oft-cited possible connection between the Bible’s Star of Bethlehem and such planetary “conjunctions” as Jupiter and Saturn are now displaying.

Three cheers for the Hubble! First launched in 1990 aboard the Space Shuttle Discovery, the storied space telescope is celebrating is thirtieth year in lonely orbit around the Earth.

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!”

This month Jupiter is entering conjunction which means it's the last chance this year to catch a glimpse of the largest planet in our solar system.

It's time to say goodbye to the mini-moon that's no bigger than your car.

What if there was another you, somewhere out there, doing all the things you wished you could’ve done?
