  • Unraveling a perplexing explosive process that occurs throughout the universe

    Novel simulation brings extraordinary fast radio bursts into the laboratory in a way once thought impossible.
  • Ghostly 'mirror world' might be cause of cosmic controversy

    New research suggests an unseen 'mirror world' of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today -- the Hubble constant problem. The Hubble constant is the rate of expansion of the universe today. Predictions for this rate are significantly slower than the rate found by our most precise local measurements. This discrepancy is one that many cosmologists have been trying to solve by changing our current cosmological model.
  • Satellite monitoring of biodiversity moves within reach

    Global biodiversity assessments require the collection of data on changes in plant biodiversity on an ongoing basis. Researchers have now shown that plant communities can be reliably monitored using imaging spectroscopy, which in the future will be possible via satellite. This paves the way for near real-time global biodiversity monitoring.
  • Physicists explain how type of aurora on Mars is formed

    Researchers have learned how a type of aurora on Mars is formed. The physicists report discrete aurora form through the interaction of the solar wind and the crust at Mars' southern hemisphere.
  • Researchers use galaxy as a 'cosmic telescope' to study heart of the young universe

    A unique new instrument, coupled with a powerful telescope and a little help from nature, has given researchers the ability to peer into galactic nurseries at the heart of the young universe.
  • Nuclear physics and extreme environments of cosmic explosions

    Researchers have helped peer inside a nova -- a type of astrophysical nuclear explosion -- without leaving Earth. These stellar events help forge the universe's chemical elements, and astronomers have explored their nature with an intense isotope beam and a custom experimental device with record-setting sensitivity.
  • Astronauts may one day drink water from ancient moon volcanoes

    If any humans had been alive 2 to 4 billion years ago, they may have looked up and seen a sliver of frost on the moon's surface. Some of that ice may still be hiding in craters on the lunar surface today.
  • Rocket engine exhaust pollution extends high into Earth's atmosphere

    Researchers assessed the potential impact of a rocket launch on atmospheric pollution by investigating the heat and mass transfer and rapid mixing of the combustion byproducts. The team modeled the exhaust gases and developing plume at several altitudes along a typical trajectory of a standard present-day rocket. They did this as a prototypical example of a two-stage rocket to transport people and payloads into Earth's orbit and beyond and found the impact on the atmosphere locally and momentarily in the mesosphere can be significant.
  • Mars' emitted energy and seasonal energy imbalance

    Seasonal imbalance between the solar energy absorbed and released by the planet Mars could be a cause of the Red Planet's dust storms, according to new research. Understanding how the system works on Mars could help scientists predict how climate change could affect Earth.
  • Extraterrestrial stone brings first supernova clues to Earth

    The extraterrestrial Hypatia stone found in Egypt could be the first tangible evidence on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic events in the universe. If the hypothesis is correct, Hypatia would be a 'forensic' clue of an epic cosmic story started sometime in the early formation of our solar system.
  • New study indicates limited water circulation late in the history of Mars

    A research team has investigated a meteorite from Mars using neutron and X-ray tomography. The technology, which will probably be used when NASA examines samples from the Red Planet in 2030, showed that the meteorite had limited exposure to water, thus making life at that specific time and place unlikely.
  • A first: Scientists grow plants in soil from the Moon

    Scientists have, for the first time, grown plants in soil from the Moon. They used soil collected during the Apollo 11, 12 and 17 missions. In their experiment, the researchers wanted to know if plants would grow in lunar soil and, if so, how the plants would respond to the unfamiliar environment, even down to the level of gene expression.
  • Astronomers reveal first image of the black hole at the heart of our galaxy

    Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies.
  • Explosion on a white dwarf observed

    When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super hot explosion and produce a fireball of X-ray radiation. A research team has now been able to observe such an explosion of X-ray light for the very first time.
  • Traveling to the centre of planet Uranus: Materials synthesis research and study in terapascal range

    Jules Verne could not even dream of this: A research team has pushed the boundaries of high-pressure and high-temperature research into cosmic dimensions. For the first time, they have succeeded in generating and simultaneously analyzing materials under compression pressures of more than one terapascal (1,000 gigapascals). Such extremely high pressures prevail, for example, at the center of the planet Uranus; they are more than three times higher than the pressure at the center of the Earth.
  • Researchers reveal the origin story for carbon-12, a building block for life

    After running simulations on the world's most powerful supercomputer, an international team of researchers has developed a theory for the nuclear structure and origin of carbon-12, the stuff of life. The theory favors the production of carbon-12 in the cosmos.
  • Astronomers find 'gold standard' star in Milky Way

    In our sun's neighborhood of the Milky Way Galaxy is a relatively bright star, and in it, astronomers have been able to identify the widest range of elements in a star beyond our solar system yet.
  • In a pair of merging supermassive black holes, a new method for measuring the void

    Researchers have devised a potentially easier way of gazing into the abyss. Their imaging technique could allow astronomers to study black holes smaller than M87's, a monster with a mass of 6.5 billion suns, harbored in galaxies more distant than M87, which at 55 million light-years away, is still relatively close to our own Milky Way.
  • New method to synchronize devices on Earth makes use of cosmic rays

    Various technologies, networks and institutions benefit from or require accurate time keeping to synchronize their activities. Current ways of synchronizing time have some drawbacks that a new proposed method seeks to address. The cosmic time synchronizer works by synchronizing devices around cosmic ray events detected by those devices. This could bring accurate timing abilities to remote sensing stations, or even underwater, places that other methods cannot serve. Early tests show promise, but the real challenge may lie in the adoption of this new technique.
  • Research breakthrough means warp speed 'Unruh effect' can finally be tested in lab settings

    A major hurdle for work at the forefront of fundamental physics is the inability to test cutting-edge theories in a laboratory setting. But a recent discovery opens the door for scientists to see ideas in action that were previously only understood in theory or represented in science fiction.
  • Hyperfast white dwarf stars provide clues for understanding supernovae

    Scientists have used computer modeling to show how a hypothesized type of supernova would evolve on the scale of thousands of years, giving researchers a way to look for examples of supernovae of this model, known as 'D6.'
  • Hubble reveals surviving companion star in aftermath of supernova

    It's not unheard of to find a surviving star at the scene of a titanic supernova explosion, which would be expected to obliterate everything around it, but new research has provided a long-awaited clue to a specific type of stellar death. In some supernova cases, astronomers find no trace of the former star's outermost layer of hydrogen. What happened to the hydrogen? Suspicions that companion stars are responsible -- siphoning away their partners' outer shell before their death -- are supported by the recent identification of a surviving companion star on the scene of supernova 2013ge.
  • Lunar soil has the potential to generate oxygen and fuel

    Soil on the moon contains active compounds that can convert carbon dioxide into oxygen and fuels, scientists report. They are now exploring whether lunar resources can be used to facilitate human exploration on the moon or beyond.
  • Identifying global poverty from space

    A new study proposes a novel method to estimate global economic wellbeing using nighttime satellite images.
  • New study reveals the effect of extended space flight on astronauts' brains

    Long-duration space flight alters fluid-filled spaces along veins and arteries in the brain, according to new research.
