There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of...

During a powerful solar blast in March, NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi's new role as a solar observatory, a powerful new...

The world's oceans have seen significant declines in certain types of microscopic plant-life at the base of the marine food chain, according to a new NASA study. The research is the first to look at global, long-term phytoplankton...

Launched in 2007, NASA's five THEMIS spacecraft have now successfully completed their 2 year mission to determine the cause of geomagnetic substorms. Because they are continuing to work perfectly, NASA is re-directing the outermost two...

Bob Behnken and Doug Hurley will make history when they break the bond from Earth in a SpaceX Crew Dragon capsule that's never been flown by humans before. But find out how the strong bond of friendship they share gives them the edge in...

A conversation with Linda Jensen, associate director for Workforce Culture and Engagement and Kerry Zarchi, the branch chief for Entry Systems and Vehicle Development and also the acting branch chief for Aerothermodynamics. Both are at...

Jason Wright, professor of astronomy and astrophysics at Penn State, has been thinking about the different technosignatures we could pick up using the telescopes we already have, and the telescopes that we could develop in the future.

There is perhaps no one better than Jim Garvin to outline the unique opportunities for research that the Artemis missions to the Moon could provide scientists on Earth. Jim is chief scientist at NASA’s Goddard Space Flight Center in...

Mark Matney and Jim Cooney describe the science of orbital debris and the details behind the shielding and avoidance maneuvers of the International Space Station. HWHAP Episode 221.

The OSIRIS-REx mission, launching in September 2016, plans to return a sample of asteroid Bennu to Earth in 2023 so that scientists can study pristine material left over from the early solar system. Dante Lauretta, Principal Investigator...

NASA Hangout: Wildfire and Climate Change

This year’s 12th Annual Goddard Film Festival will highlight Goddard’s achievements over the past year in astrophysics, Earth science, heliophysics and planetary science. Highlights include recent and upcoming missions such as the Nancy...

Lightning in the clouds is directly linked to events that produce some of the highest-energy light naturally made on Earth: terrestrial gamma-ray flashes (TGFs). An instrument aboard NASA's Fermi Gamma-ray Space Telescope was recently...

The Landsat Data Continuity Mission (LDCM) is a collaboration between NASA and the U.S. Geological Survey that will continue the Landsat Program's 40-year data record of monitoring Earth's landscapes from space. LDCM will expand and...

Counting down the Top Five Earth As Art images, as voted on by the public. Landsat has been collecting data of the Earth's surface since 1972. Some of the images are visually striking, and they have been selected for the "Earth As Art"...

Bennu's Journey is a 6-minute animated movie about NASA's OSIRIS-REx mission, Asteroid Bennu, and the formation of our solar system. Born from the rubble of a violent collision, hurled through space for millions of years, Asteroid Bennu...

The Cassini-Huygens mission arrived at Saturn in 2004, beginning an epic thirteen-year tour of the ringed planet and its many moons. Cassini and its companion probe, Huygens, were an international collaboration between NASA and the...

Mars bears ample evidence of a wet past, but scientists debate just how much water the planet has lost over time. Now, isotopic measurements by researchers at NASA’s Goddard Space Flight Center reveal that an ocean covered approximately...

Mars's thick early atmosphere was likely lost to space, and the Sun is a potential culprit. When high-energy solar photons strike the upper Martian atmosphere they can ionize gas molecules, causing the atmosphere to erode over time.

This video explains the way IBEX will create a global map of the boundaries of our solar system. The two Voyager spacecraft launched in the 1970s gave data for two points on the map, but by using energetic neutral atoms, IBEX images the...

NASA is working alongside Conservation International and the Liberian Government through the Environmental Protection Agency (EPA) to pilot an innovative and replicable approach to more accurately map ecosystems to support effective...

About 1 million miles away from the nearest eye surgeon, NASA’s James Webb Space Telescope will be able to perfect its own vision while in orbit. Though the Webb telescope will focus on stars and galaxies approximately 13.5 billion...

Beyond the asteroid belt are "fossils of planet formation" known as the Trojan asteroids. These primitive bodies share Jupiter's orbit in two vast swarms, and may hold clues to the formation and evolution of our solar system. Now, NASA...

This image, taken with the Hubble Space Telescope, shows a distant galaxy located in the constellation Fornax. It is the largest and one of the most complete Einstein rings ever discovered. This object’s unusual shape is the result of...
