  • Hubble solves cosmic 'whodunit' with interstellar forensics
    on March 22, 2018 at 7:02 pm

    On the outskirts of our galaxy, a cosmic tug-of-war is unfolding-and only NASA's Hubble Space Telescope can see who's winning. […]

  • Mars' oceans formed early, possibly aided by massive volcanic eruptions
    on March 19, 2018 at 4:42 pm

    A new theory about how oceans and volcanoes interacted during the early history of Mars supports the idea that liquid water was once abundant and may still exist underground. Geophysicists propose that the oceans originated several hundred million years earlier than thought, as the volcanic province Tharsis formed, and that greenhouse gases enabled the oceans. The theory predicts smaller oceans, more in line with estimates of water underground and at the poles today. […]

  • Scientists detect radio echoes of a black hole feeding on a star
    on March 19, 2018 at 3:58 pm

    A scientist has detected radio echoes of a black hole feeding on a star, suggesting black hole emits a jet of energy proportional to the stellar material it gobbles up. […]

  • 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

  • Double or nothing: Astronomers rethink quasar environment
    on March 13, 2018 at 1:30 pm

    Astronomers have identified nearly 200 'protoclusters,' the progenitors of galaxy clusters, in the early Universe, about 12 billion years ago, about ten times more than previously known. They also found that quasars don't tend to reside in protoclusters; but if there is one quasar in a protocluster, there is likely a second nearby. This result raises doubts about the relation between protoclusters and quasars. […]

  • Arrested development: Hubble finds relic galaxy close to home
    on March 12, 2018 at 6:15 pm

    Astronomers have put NASA's Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient 'relic galaxy' in our own cosmic backyard. […]

    on March 12, 2018 at 12:50 pm

    Scientists report the existence of 15 new planets -- including one 'super-Earth' that could harbor liquid water -- orbiting small, cool stars near our solar system. These stars, known as red dwarfs, are of enormous interest for studies of planetary formation and evolution. […]

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

    Scientists have developed a model that simulates how shocks following coronal mass ejections, or CMEs, propagate from the sun -- an effort made possible only by combining data from three different NASA satellites. […]

  • Making a splash in search for interstellar water
    on March 9, 2018 at 5:52 pm

    Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen. It requires the special conditions found deep within frigid molecular clouds, where dust shields against destructive ultraviolet light and aids chemical reactions. NASA's James Webb Space Telescope will peer into these cosmic reservoirs to gain new insights into the origin and evolution of water and other key building blocks for habitable planets. […]

  • New 3-D measurements improve understanding of geomagnetic storm hazards
    on March 8, 2018 at 6:33 pm

  • First laboratory simulation of exoplanet atmospheric chemistry
    on March 8, 2018 at 3:51 pm

    Scientists have conducted the first lab experiments on haze formation in simulated exoplanet atmospheres, an important step for understanding upcoming observations of planets outside the solar system with the James Webb Space Telescope. […]

  • NASA Juno finds Jupiter's jet-streams are unearthly
    on March 7, 2018 at 11:34 pm

    Data collected by NASA's Juno mission to Jupiter indicate that the atmospheric winds of the gas-giant planet run deep into its atmosphere and last longer than similar atmospheric processes found here on Earth. […]

  • Weather satellites aid search and rescue capabilities
    on March 7, 2018 at 4:55 pm

    The same satellites that identify severe weather can help save you from it. NOAA's GOES series satellites carry a payload supported by NASA's Search and Rescue (SAR) office, which researches and develops technologies to help first responders locate people in distress worldwide, whether from a plane crash, a boating accident or other emergencies. […]

  • ALMA reveals inner web of stellar nursery
    on March 7, 2018 at 2:52 pm

    New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot and fiery in this dramatic picture, but in reality are so cold that astronomers must use telescopes like ALMA to observe them. […]

  • Hubble finds huge system of dusty material enveloping the young star HR 4796A
    on March 6, 2018 at 6:17 pm

    Astronomers have used NASA's Hubble Space Telescope to uncover a vast, complex dust structure, about 150 billion miles across, enveloping the young star HR 4796A. […]

  • 70-year-old mystery of how magnetic waves heat the Sun cracked
    on March 6, 2018 at 2:33 pm

  • Comet 'Chury's' late birth
    on March 5, 2018 at 7:25 pm

    Comets which consist of two parts, like Chury, can form after a catastrophic collision of larger bodies. Such collisions may have taken place in a later phase of our solar system, which suggests that Chury can be much younger than previously assumed. […]

  • Unprecedentedly wide and sharp dark matter map
    on March 2, 2018 at 3:18 pm

    A research team released an unprecedentedly wide and sharp dark matter map based on the newly obtained imaging data by Hyper Suprime-Cam on the Subaru Telescope. The dark matter distribution is estimated by the weak gravitational lensing technique. The team found indications that the number of dark matter halos could be inconsistent with what the simplest cosmological model suggests. This could be a new clue to understanding why the expansion of the universe is accelerating. […]

  • Hubble observes exoplanet atmosphere in more detail than ever before
    on March 1, 2018 at 7:41 pm

    An international team of scientists has used the NASA/ESA Hubble Space Telescope to study the atmosphere of the hot exoplanet WASP-39b. By combining this new data with older data they created the most complete study yet of an exoplanet atmosphere. The atmospheric composition of WASP-39b hints that the formation processes of exoplanets can be very different from those of our own Solar System giants. […]

  • Can strongly lensed type 1a supernovae resolve cosmology's biggest controversy?
    on March 1, 2018 at 2:48 pm

    Astrophysicists have discovered how to control the 'micolensing' effects of strongly lensed Type 1a Supernovae with supercomputers at NERSC. Armed with this knowledge they believe they will be able to find 1,000 strongly lensed Type Ia supernovae in realtime from LSST data -- that's 20 times more than previous expectations. […]

  • Unlocking the Secrets of the Universe
    on February 28, 2018 at 6:11 pm

    After 12 years of experimental effort, a team of scientists has detected the fingerprints of the earliest stars in the universe. Using radio signals, the detection provides the first evidence for the oldest ancestors in our cosmic family tree, born by a mere 180 million years after the universe began. […]

    on February 28, 2018 at 3:32 pm

    A new explanation for the Moon's origin has it forming inside the Earth when our planet was a seething, spinning cloud of vaporized rock, called a synestia. The new model resolves several problems in lunar formation. […]

  • When ‘colder’ means ‘hotter’: Explaining the increasing temperature of cooling granular...
    on February 28, 2018 at 2:22 pm

    A mathematician has developed a theory to explain ‘heating by cooling’, where the temperature of a granular gas increases while the total energy drops down - a peculiar phenomenon which can be observed both on Earth and in space. […]
