In space, microgravity changes the body. Body fluids shift from the legs toward the head, the back of our eyes flatten, we lose muscle strength, our bones lose some of their density, and even the amount of blood pumped by the heart with each beat drops. To learn more about how microgravity affects the human body and develop new ways to help astronauts stay healthy, scientists are asking dozens of volunteers to spend 60 days in bed with their heads tilted down at a specific angle. This research a...

The James Webb Space Telescope is doing something astronomers dreamed about for decades: peering into our universe’s early past, a period known as cosmic dawn. A new NASA documentary—also called Cosmic Dawn—chronicles the inside story of Webb’s design, construction, and launch. John Mather, who won the 2006 Nobel Prize for Physics, proposed the telescope and led its science team for decades. In this interview, Mather talks about his life, his research, and the pre-dawn phone call telling him he ...

Life all over the planet—even far from the coasts—depends on the oceans. A pair of NASA satellites, PACE and SWOT, is giving us a fresh look at Earth’s water. PACE tracks color changes driven by tiny plankton, which give us a big-picture view of ocean life. By measuring sea level height from space, SWOT shows ocean currents and other features in new detail. NASA scientists Cecile Rousseaux, Kelsey Bisson, and Josh Willis dive into new research with a lot of color and a little bit of rock and rol...

How did life begin? It’s one of science’s biggest questions, but it’s impossible to answer on Earth, where ancient clues have been buried by the planet’s shifting surface. Instead, scientists are looking beyond our own planet, to asteroids like Bennu, a distant fragment of a lost world. In 2023, NASA’s OSIRIS-REx spacecraft collected a sample of Bennu’s surface and brought it back to Earth. Ever since, scientists have been hard at work studying the fragments of asteroid Bennu. Now, they’re ready...

The Moon’s South Pole is a bizarre landscape. Mountain ridges glow in perpetual sunlight while deep craters freeze in billion-year-old shade. Yet hidden in the depths of those shadowed craters, under temperatures almost three times colder than the frostiest day in Antarctica, lurks something familiar–water ice. In the future, that ice could sustain human explorers or be broken apart into hydrogen and oxygen to refuel rockets. Join Brett Denevi, Artemis III geology team lead, to learn why NASA pl...
