  • Vast luminous nebula poses a cosmic mystery

    Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an 'enormous Lyman-alpha nebula' (ELAN), it is the brightest and among the largest of these rare objects, only a handful of which have been observed.
  • Space dust deploy bubble parachutes on their fiery descent, scientists discover

    Bubbles acting like parachutes are deployed by some cosmic dust particles on their entry into Earth’s atmosphere, preventing them from burning up.
  • From rocks in Colorado, evidence of a 'chaotic solar system'

    Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists has found evidence confirming a critical theory of how the planets in our solar system behave in their orbits around the sun. The finding is important because it provides the first hard proof for what scientists call the ''chaotic solar system.'
  • NASA telescope reveals largest batch of Earth-size, habitable-zone planets around single star

    NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
  • Surprising dunes on comet Chury

    Surprising images from the Rosetta spacecraft show the presence of dune-like patterns on the surface of comet Chury. Researchers have studied the available images and modeled the outgassing of vapor to try to explain the phenomenon. They show that the strong pressure difference between the sunlit side of the comet and that in shadow generates winds able to transport grains and form dunes.
  • Possible dark matter ties in Andromeda Galaxy

    NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.
  • Brightest neutron star yet has a multipolar magnetic field

    Scientists have identified a neutron star that is consuming material so fast it emits more x-rays than any other. Its extreme brightness can only be explained if the star has a complex multipolar magnetic field, the researchers say.
  • Prediction: More gas-giants will be found orbiting Sun-like stars

    New planetary formation models indicate that there may be an undiscovered population of gas giant planets orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn.
  • Experiments call origin of Earth's iron into question

    New research reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.
  • Origin of spooky meteor noises reappraised

    Sound travels more slowly than light. Then why do sounds of meteors entering Earth's atmosphere precede or accompany the sight of them? Researchers believe they have an answer.
  • Mapping the family tree of stars

    Astronomers are borrowing principles applied in biology and archaeology to build a family tree of the stars in the galaxy. By studying chemical signatures found in the stars, they are piecing together these evolutionary trees looking at how the stars formed and how they are connected to each other. The signatures act as a proxy for DNA sequences. It's akin to chemical tagging of stars and forms the basis of a discipline astronomers refer to as Galactic archaeology.
  • Why are there different 'flavors' of iron around the Solar System?

    New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created.
  • Examining exploding stars through the atomic nucleus

    Imagine being able to view microscopic aspects of a classical nova, a massive stellar explosion on the surface of a white dwarf star (about as big as Earth), in a laboratory rather than from afar via a telescope. Cosmic detonations of this scale and larger created many of the atoms in our bodies. A safe way to study these events in laboratories on Earth is to investigate the exotic nuclei or 'rare isotopes' that influence them.
  • Historic detection of gravitational waves

    A scientist who has been involved with nearly every aspect of the development and ultimate success of the Laser Interferometer Gravitational-wave Observatory (LIGO), will give a talk about the project's historic detection of gravitational waves.
  • Hubble spotlights a celestial sidekick

    Technically, this picture is merely a sidekick of the actual object of interest -- but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its own.
  • Alien particles from outer space are wreaking low-grade havoc on personal electronic devices

    Alien subatomic particles raining down from outer space are wreaking low-grade havoc on your smartphones, computers and other personal electronic devices, say researchers.
  • Minor planet named Bernard

    A minor planet in the Solar System will officially be known as Bernardbowen from today after Australian citizen science project theSkyNet won a competition to name the celestial body.
  • Radial acceleration relation found in all common types of galaxies

    The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team of researchers reports. This provides further support that the relation is tantamount to a new natural law, the researchers say.
  • Geology of Ceres illuminates origin of organics

    NASA's Dawn spacecraft recently detected organic-rich areas on Ceres. Scientists evaluated the geology of the regions to conclude that the organics are most likely native to the dwarf planet. Data from the spacecraft suggest that the interior of Ceres is the source of these organic materials, as opposed to arriving via impacting asteroids or comets, according to a new article.
  • Planeterrella recreates Earth's vivid lightshows in miniature

    A new device has been built to recreate Earth's auroras and other space phenomena in miniature. The planeterrella is one of just a handful in the United States.
  • Deadly spider's unique spinning technique could inspire tougher materials

    The unique spinning technique used by the venomous American brown recluse spider could inspire scientific developments and improve materials used in space travel, suggest scientists.
  • How disturbances interact with a dynamic space-time fabric: 'Field patterns' as a new mathematical object

    Mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory is called 'field patterns.'
  • Watery past on Mars: Searching for past life forms

    An area on Mars that appears to have been flooded in the past offers a prime target to search for past life forms on the Red Planet.
  • Astronomers propose a cell phone search for galactic fast radio bursts

    Fast radio bursts seem to come from distant galaxies, but there is no obvious reason that, every once in a while, an FRB wouldn't occur in our own Milky Way galaxy too. If it did, astronomers suggest that it would be 'loud' enough that a global network of cell phones or small radio receivers could 'hear' it.
  • Ancient jars found in Judea reveal Earth's magnetic field is fluctuating, not diminishing

    Surprising new evidence derived from ancient ceramics proves that the Earth's geomagnetic force fluctuates -- not diminishes -- over time, researchers say.
