  • Space radiation more hazardous: Implication sfor astronauts and satellites
    on March 15, 2018 at 3:06 pm

    It might sound like something from a science fiction plot - astronauts traveling into deep space being bombarded by cosmic rays - but radiation exposure is science fact. As future missions look to travel back to the moon or even to Mars, new research cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology. […]

  • Jupiter's atmospheric beauty is more than skin deep
    on March 15, 2018 at 1:12 pm

    In the year and a half NASA's Juno spacecraft has been orbiting Jupiter, the scientists have discovered that the orange and white bands that characterize Jupiter's outer atmosphere extend thousands of miles into the gas giant's atmosphere. […]

  • Three NASA satellites recreate solar eruption in 3-D
    on March 9, 2018 at 10:07 pm

  • NASA's James Webb Space Telescope to reveal secrets of the Red Planet
    on February 20, 2018 at 5:47 pm

    Mars rovers and orbiters have found signs that Mars once hosted liquid water on its surface. Much of that water escaped over time. How much water was lost, and how does the water that’s left move from ice to atmosphere to soil? During its first year of operations, NASA’s James Webb Space Telescope will seek answers. Webb also will study mysterious methane plumes that hint at possible geological or even biological activity. […]

  • Scientists discover almost 100 new exoplanets
    on February 15, 2018 at 3:57 pm

    Based on data from NASA's K2 mission an international team of scientists have just confirmed nearly 100 new exoplanets, planets located outside our solar system. This brings the total number of new exoplanets found with the K2 mission up to almost 300. […]

  • Researchers build alien ocean to test NASA outer space submarine
    on February 7, 2018 at 8:18 pm

    Building a submarine gets tricky when the temperature drops to -300 Fahrenheit and the ocean is made of methane and ethane. Researchers are working to determine how a submarine might work on Titan, the largest of Saturn's many moons and the second largest in the solar system. The space agency plans to launch a real submarine into Titan seas in the next 20 years. […]

  • Did surface life evolve on Mars? Newly published research casts increased doubt
    on February 6, 2018 at 3:03 pm

    Surface life on Earth is abundant because of the availability of sunlight, surface water, generally moderate climate conditions. But the planet Mars would have never experienced such habitable conditions at the surface, according to new research. However, below the surface, hydrothermal systems on Mars may have provided the right environment for life on the Red Planet, researchers argue. […]

  • Atmospheres of exoplanets in TRAPPIST-1 habitable zone probed
    on February 5, 2018 at 4:33 pm

    Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of the Earth-sized planets within the habitable zone around the nearby star TRAPPIST-1. Hubble reveals that at least three of the exoplanets (d, e, and f) do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune. The results, instead, favor more compact atmospheres like those of Earth, Venus, and Mars. […]

  • Microbes may help astronauts transform human waste into food
    on January 26, 2018 at 4:04 am

    Human waste may one day be a valuable resource for astronauts on deep-space missions. Now, a research team has shown that it is possible to rapidly break down solid and liquid waste to grow food with a series of microbial reactors, while simultaneously minimizing pathogen growth. […]

  • Viruses are everywhere, maybe even in space
    on January 18, 2018 at 7:25 pm

    Viruses are the most abundant and one of the least understood biological entities on Earth. They might also exist in space, but as of yet scientists have done almost no research into this possibility. […]

    on January 18, 2018 at 3:08 pm

    Miniaturized scientific instruments and new microbiology techniques successfully identified and characterized microorganisms living in Arctic permafrost -- one of the closest analogs to Mars on Earth. By avoiding delays that come with having to return samples to a laboratory for analysis, the methodology could also be used on Earth to detect and identify pathogens during epidemics in remote areas. […]

    on January 12, 2018 at 3:39 am

    In a technology first, a team of engineers has demonstrated fully autonomous X-ray navigation in space -- a capability that could revolutionize NASA's ability in the future to pilot robotic spacecraft to the far reaches of the solar system and beyond. […]

  • Magnified and stretched out image of extremely distant galaxy
    on January 11, 2018 at 9:29 pm

    An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing. […]

  • Steep slopes on Mars reveal structure of buried ice on Red Planet
    on January 11, 2018 at 7:17 pm

    Researchers have found eight sites where thick deposits of ice beneath Mars' surface are exposed in faces of eroding slopes. The ice was likely deposited as snow long ago. The deposits hold clues about Mars' climate history and also may make frozen water more accessible than previously thought to future robotic or human exploration missions. […]

  • All missions on board for NASA heliophysics research
    on November 27, 2017 at 5:47 pm

    Scientists have been studying the near-Earth environment for the better part of a century, but many mysteries -- like where the energetic particles that pervade the area originate and become energized -- still remain. In a new type of collaborative study, scientists combined data from 16 separate NASA and Los Alamos National Laboratory spacecraft to understand how a particle phenomenon in the magnetic environment around Earth occurs. These events, called substorms, can cause auroras, disrupt GPS communications and, at their most intense, damage power grids. […]
