  • Deep space radiation treatment reboots brain's immune system

    NASA and private company SpaceX plan to send humans to Mars within the next 15 years -- but need to figure out how to protect astronauts from the dangerous cosmic radiation of deep space. Now neuroscientists have identified a potential treatment for the brain damage caused by cosmic rays -- a drug that prevents memory impairment in mice exposed to simulated space radiation.
  • First interstellar immigrant discovered in the solar system

    A new study has discovered the first known permanent immigrant to our solar system. The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system.
  • A new map for a birthplace of stars

    A research group has created the most detailed maps yet of a vast seedbed of stars similar to Earth's sun.
  • Astronomers release most complete ultraviolet-light survey of nearby galaxies

    Capitalizing on the unparalleled sharpness and spectral range of NASA's Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.
  • Vast ionized hydrogen cloud in the Whirlpool Galaxy revealed by ultra-sensitive telescope

    No one has ever seen what astronomers first observed using a refurbished 75-year-old telescope in the Arizona mountains. What it was turned out to be a massive cloud of ionized hydrogen gas spewed from a nearby galaxy and then essentially 'cooked' by radiation from the galaxy's central black hole.
  • Evidence for stars forming just 250 million years after Big Bang

    Astronomers have used observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO's Very Large Telescope (VLT) to determine that star formation in the very distant galaxy MACS1149-JD1 started at an unexpectedly early stage, only 250 million years after the Big Bang. This discovery also represents the most distant oxygen ever detected in the universe and the most distant galaxy ever observed by ALMA or the VLT.
  • Astronomers find fastest-growing black hole known in space

    Astronomers have found the fastest-growing black hole known in the universe, describing it as a monster that devours a mass equivalent to our sun every two days.
  • Unusual laser emission from the Ant Nebula

    Astronomers have discovered an unusual laser emission that suggests the presence of a double star system hidden at the heart of the 'spectacular' Ant Nebula. The extremely rare phenomenon is connected to the death of a star and was discovered in observations made by European Space Agency's Herschel space observatory.
  • Orbital variations can trigger 'snowball' states in habitable zones around sunlike stars

    Aspects of an otherwise Earthlike planet's tilt and orbital dynamics can severely affect its potential habitability -- even triggering abrupt 'snowball states' where oceans freeze and surface life is impossible, according to new research from astronomers.
  • Water plumes on Jupiter's moon Europa?

    Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter's moon Europa has the ingredients to support life. The data provide independent evidence that the moon's subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell.
  • Scientists use Dorset, UK, as model to help find traces of life on Mars

    By studying a stream on the UK coast, experts have calculated how much organic matter we might find on Mars, and where to look.
  • Frequency-stable laser systems for space

    For the first time a frequency reference based on molecular iodine was successfully demonstrated in space! What sounds a bit like science fiction is an important step towards laser interferometric distance measurements between satellites as well as for future global navigation satellite systems based on optical technologies. The frequency reference tests were carried out on May 13 on board the sounding rocket TEXUS54.
  • Could a multiverse be hospitable to life?

    A multiverse -- where our universe is only one of many -- might not be as inhospitable to life as previously thought, according to new research.
  • Dozens of binaries from Milky Way's globular clusters could be detectable by LISA

    A next-generation observatory, called LISA, is expected to be in space in 2034, and it will be sensitive to gravitational waves of a lower frequency than those detected by the Earth-bound Laser Interferometer Gravitational-Wave Observatory (LIGO).
  • Levitation yields better neutron-lifetime measurement

    Being repulsive can have its advantages. In the case of an experiment at Los Alamos National Laboratory's linear accelerator, a repulsive magnetic field and a clever detector system are allowing ultracold neutrons to be levitated so their actual lifetimes can be more accurately measured.
  • Atmospheric seasons could signal alien life

    To complement traditional biosignatures, scientists are developing the first quantitative framework for dynamic biosignatures based on seasonal changes in the Earth's atmosphere.
  • New magnetic process in turbulent space

    Explorations in Earth's space environment by NASA's Magnetospheric Multiscale spacecraft have discovered a surprising new magnetic event in turbulent plasma.
  • Exiled asteroid discovered in outer reaches of solar system

    Astronomers have used ESO telescopes to investigate a relic of the primordial solar system. The team found that the unusual Kuiper Belt Object 2004 EW95 is a carbon-rich asteroid, the first of its kind to be confirmed in the cold outer reaches of the Solar System. This curious object likely formed in the asteroid belt between Mars and Jupiter and has been flung billions of kilometers from its origin to its current home in the Kuiper Belt.
  • Why does the Sun's Corona sizzle at one million degrees Fahrenheit?

    Physicists have discovered a phenomenon that may begin to untangle what they call 'one of the greatest challenges for solar modeling' -- determining the physical mechanisms that heat the upper atmosphere to 1 million degrees Fahrenheit and higher.
  • Earth's orbital changes have influenced climate, life forms for at least 215 million years

    Every 405,000 years, gravitational tugs from Jupiter and Venus slightly elongate Earth's orbit, an amazingly consistent pattern that has influenced our planet's climate for at least 215 million years and allows scientists to more precisely date geological events like the spread of dinosaurs, according to a new study.
  • Mission to study how Mars was made

    NASA's Mars Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission is on a 300-million-mile (483-million-kilometer) trip to Mars to study for the first time what lies deep beneath the surface of the Red Planet. InSight is scheduled to land on the Red Planet around 3 p.m. EST (noon PST) Nov. 26, where it will conduct science operations until Nov. 24, 2020, which equates to one year and 40 days on Mars, or nearly two Earth years.
  • Astronomers find exoplanet atmosphere free of clouds

    Scientists have detected an exoplanet atmosphere that is free of clouds, marking a pivotal breakthrough in the quest for greater understanding of the planets beyond our solar system.
  • What will happen when our sun dies?

    Scientists agree the sun will die in approximately five billion years, but they weren't sure what would happen next -- until now. A team of international astronomers predicts it will turn into a massive ring of luminous, interstellar gas and dust, known as a planetary nebula.
  • Mars growth was stunted by early giant planetary instability

    An astrophysics team explains why the growth of Mars was stunted by an orbital instability among the outer solar system's giant planets in a new study on the evolution of the young solar system. The study builds on the widely accepted Nice Model, which invokes a planetary instability to explain many peculiar observed aspects of the outer solar system. The research shows how planet accretion (growth) is halted by the outer solar system instability.
  • May the forest be with you: GEDI moves toward launch to space station

    GEDI (pronounced like 'Jedi,' of Star Wars fame) is a first-of-its-kind laser instrument designed to map the world's forests in 3-D from space. These measurements will help fill in critical gaps in scientists' understanding of how much carbon is stored in the world's forests, the potential for ecosystems to absorb rising concentrations of carbon dioxide in Earth's atmosphere, and the impact of forest changes on biodiversity.
