  • Red wine's resveratrol could help Mars explorers stay strong
    18 July 2019, 2:53 pm
    Mars is about 9 months from Earth with today's tech, NASA reckons. As the new space race hurtles forward, researchers are asking: how do we make sure the winners can still stand when they reach the finish line? A new study shows that resveratrol substantially preserves muscle mass and strength in rats exposed to the wasting effects of simulated Mars gravity.

  • Supernova observation first of its kind using NASA satellite
    16 July 2019, 9:23 pm
    Researchers have published findings about a supernova observed using TESS, adding new insights to long-held theories about the elements left behind after a white dwarf star explodes into a supernova.

  • Gaia starts mapping the galactic bar in the Milky Way
    16 July 2019, 6:48 pm
    The first direct measurement of the bar-shaped collection of stars at the centre of our Milky Way galaxy has been made by combining data from the Gaia mission with complementary observations by ground- and space-based telescopes.

  • New Hubble constant measurement adds to mystery of universe's expansion rate
    16 July 2019, 3:55 pm
    Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors. The revised measurement falls in the center of a hotly debated question in astrophysics that may lead to a new interpretation of the universe's fundamental properties.

  • A material way to make Mars habitable
    15 July 2019, 5:42 pm
    New research suggests that regions of the Martian surface could be made habitable with a material -- silica aerogel -- that mimics Earth's atmospheric greenhouse effect. Through modeling and experiments, the researchers show that a 2- to 3-centimeter-thick shield of silica aerogel could transmit enough visible light for photosynthesis, block hazardous ultraviolet radiation, and raise temperatures underneath permanently above the melting point of water, all without the need for any internal heat source.

  • Super salty, subzero Arctic water provides peek at possible life on other planets
    12 July 2019, 4:57 pm
    Researchers have discovered thriving communities of bacteria in Alaskan 'cryopegs,' trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures. The setting may be similar to environments on Mars, Saturn's moon Titan, or other bodies farther from the sun.

  • Moon-forming disk discovered around distant planet
    11 July 2019, 9:09 pm
    Using Earth's most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one that is believed to have birthed the moons of Jupiter.

  • Hubble uncovers black hole that shouldn't exist
    11 July 2019, 5:48 pm
    As if black holes weren't mysterious enough, astronomers have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

  • Alternating currents cause Jupiter's aurora
    11 July 2019, 4:56 pm
    An international research team has measured the system of currents that generates Jupiter's aurora. The scientists found out that sulphur dioxide gas from the gas giant's Moon Io is the cause of the system of currents.

  • Pair of supermassive black holes discovered on a collision course
    10 July 2019, 6:15 pm
    Astronomers have spotted a pair of supermassive black holes on a collision course in a galaxy 2.5 billion light-years away. Coincidentally, the pair will begin producing gravitational waves in roughly 2.5 billion years, the researchers estimate. The duo can be used to estimate how many supermassive black hole pairs are detectable in the nearby, present-day universe and when the historic first detection of the background 'hum' of their gravitational waves will be made.

  • Holes in the Universe sharpen cosmic measurements
    10 July 2019, 6:15 pm
    Regions of the Universe containing very few or no galaxies -- known as voids -- can help measure cosmic expansion with much greater precision than before, according to new research.

  • Exactly how fast is the universe expanding?
    9 July 2019, 5:02 pm
    The collision of two neutron stars (GW170817) flung out an extraordinary fireball of material and energy that is allowing a a team of astrophysicists to calculate a more precise value for the Hubble constant, the speed of the universe's expansion. Previous estimates put the value between 66 and 90 km/s/Mpc, which this team refined to between 65.3 and 75.6 km/s/Mpc.

  • New method may resolve difficulty in measuring universe's expansion
    8 July 2019, 8:00 pm
    Radio telescope observations have made it possible for astronomers to use mergers of neutron-star pairs as a valuable new tool for measuring the Universe's expansion.

  • Supercomputer shows 'Chameleon Theory' could change how we think about gravity
    8 July 2019, 7:11 pm
    Supercomputer simulations of galaxies have shown that Einstein's theory of General Relativity might not be the only way to explain how gravity works or how galaxies form.

  • Deep-CEE: The AI deep learning tool helping astronomers explore deep space
    5 July 2019, 1:14 am
    Galaxy clusters are some of the most massive structures in the cosmos, but despite being millions of lightyears across, they can still be hard to spot. Researchers have turned to artificial intelligence for assistance in finding galaxy clusters, developing 'Deep-CEE' (Deep Learning for Galaxy Cluster Extraction and Evaluation), a novel deep learning technique to speed up the process of finding them.
