NASA will host a live Science Chat at 2 p.m. EST Wednesday, Nov. 7, to discuss upcoming encounters of two of the agency’s planetary missions. […]

NASA's Marshall Center will host the 8th annual International Observe the Moon Night celebration at the U.S. Space & Rocket Center Oct. 20 from 5:30-8:30 p.m. CDT. Members of the public and the Huntsville-area media are invited to attend. […]

Using NASA’s Hubble and Kepler space telescopes, astronomers have uncovered tantalizing evidence of what could be the first discovery of a moon orbiting a planet outside our solar system. […]

Members of NASA’s New Horizons spacecraft team will host a Science Chat at 1 p.m. EDT Wednesday, Sept. 19, on humanity’s farthest planetary flyby, scheduled to occur Jan. 1 when the spacecraft encounters a mysterious object in the Kuiper Belt nicknamed “Ultima Thule.&rdquo […]

On the one-year anniversary of the historic 2017 Eclipse Across America, NASA will host a Science Chat at 10:30 a.m. EDT, Tuesday, Aug. 21, to discuss new science data and the public impact of the celestial event experienced by millions. […]

Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible. […]

Transforming the inhospitable Martian environment into a place astronauts could explore without life support is not possible without technology well beyond today’s capabilities because Mars does not retain enough accessible carbon dioxide that could be put back into the atmosphere to warm the planet. […]

NASA’s MAVEN spacecraft just found a new type of Martian aurora that occurs over much of the day side of the Red Planet, where auroras are very hard to see. […]

For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. […]

The Independent Review Board (IRB) established by NASA to assess progress on its James Webb Space Telescope has unanimously recommended that development on the world’s premier science observatory should continue; NASA has established a new launch date for Webb of March 30, 2021. […]

Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research has found evidence that sometimes the lakes would take on so much water that they overflowed and burst from the sides of their basins, creating catastrophic floods that carved canyons very rapidly, perhaps in a matter of weeks. […]

The first known interstellar object to visit our solar system -- named 'Oumuamua -- was detected in October 2017 by Hawaii's Pan-STARRS 1 telescope. But it was too faint for NASA's Spitzer Space Telescope to detect when it looked more than two months after the object's closest approach to Earth in early September. That 'non-detection' puts a new limit on how large the strange object can be, astronomers now report. […]

Scientists have created the soundtrack of the 5,000th Mars sunrise captured by the robotic exploration rover, Opportunity, using data sonification techniques to create a two-minute piece of music. […]

Earth's water may have originated from both asteroidal material and gas left over from the formation of the Sun, according to new research. The new finding could give scientists important insights about the development of other planets and their potential to support life. […]

The presence of water on Mars has been theorized for centuries. Early telescopes revealed ice caps, and early astronomers noted channels that were hypothesized to be natural rivers or creature-created canals. […]

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping. […]

New insights have been gained about stellar winds, streams of high-speed charged particles called plasma that blow through interstellar space. These winds, created by eruptions from stars or stellar explosions, carry with them strong magnetic fields which can interact with or effect other magnetic fields, such as those that surround planets like Earth. To understand these processes, researchers are employing laboratory experiments to study magnetic flows up close. […]

Combined observations of Comet McNaught -- one of the brightest comets visible from Earth in the past 50 years -- have revealed new insights on the nature of comets and their relationship with the Sun. […]

NASA's Dawn spacecraft has gone silent, ending a historic mission that studied time capsules from the solar system's earliest chapter. […]

Mars' organic carbon may have originated from a series of electrochemical reactions between briny liquids and volcanic minerals, according to analyses of three Martian meteorites. The discovery that natural systems can form a small corrosion-powered battery that drives electrochemical reactions between minerals and surrounding liquid has major implications for astrobiology. A similar process could occur anywhere that igneous rocks are surrounded by brines, including the subsurface oceans of […]
