A dramatic Martian landscape can be seen in a new image taken from space, showing NASA's Curiosity rover examining a location called "Woodland Bay." It's just one of many stops the rover has made in an area referred to as the "clay-bearing unit" on the side of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain inside of Gale Crater.

In the midst of the space race, Hereward Lester Cooke, the former co-director of the NASA Art Program, observed, “Space travel started in the imagination of the artist.”

As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

It’s easy to take for granted the detailed, almost real-time knowledge of Mars that we have at our fingertips. After all, in the not-too-distant past, Mars was largely mysterious. All we had were ground-based images of the planet. Now? Now we have daily weather reports and images of dust storms.

With careful planning and dashes of creativity, engineers have been able to keep NASA's Voyager 1 and 2 spacecraft flying for nearly 42 years — longer than any other spacecraft in history. To ensure that these vintage robots continue to return the best science data possible from the frontiers of space, mission engineers are implementing a new plan to manage them. And that involves making difficult choices, particularly about instruments and thrusters

NASA is making a new effort to encourage women to pursue STEM careers

An unprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico—and it’s likely here to stay. Scientists at the University of South Florida in St. Petersburg's College of Marine Science used NASA satellite observations to discover and document the largest bloom of macroalgae in the world, dubbed the Great Atlantic Sargassum Belt, as reported in Science.

This 8-image mosaic is of Sojourner, NASA's first rover on Mars, and was acquired during the late afternoon on Sol 2, the second Martian day on the planet as part of an "insurance panorama." Sojourner arrived aboard the Mars Pathfinder on July 4, 1997.

It seems like the stuff of dreams, the idea that humanity will one day venture beyond the Solar System and become an interstellar species. Who knows? Given enough time and the right technology (and assuming there’s not some serious competition), we might even be able to colonize the entire Milky Way galaxy someday. And while this seems like a far-off prospect at best, it makes sense to contemplate what a process like this would entail.

NASA’s Apollo program was one of the most challenging technological achievements in the 20th century. Beyond the space race and exploration, it contributed to several inventions and innovations that are still having an impact on our lives. But at the same time, there are several myths regarding what technologies actually came out of it.

The ESA has announced a new mission to explore a comet. The Comet Interceptor mission will have a spacecraft wait in space until a pristine comet approaches the inner Solar System. Then it will make a bee line for it, and do some ground-breaking science.
