  • Part of the Universe’s missing matter found
    16 September 2021, 5:46 pm
    Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. An international research team has now mapped a galactic wind for the first time. This unique observation helped to reveal where some of the Universe's missing matter is located and to observe the formation of a nebula around a galaxy.

  • Have we detected dark energy? Scientists say it’s a possibility
    15 September 2021, 7:51 pm
    Dark energy, the mysterious force that causes the universe to accelerate, may have been responsible for unexpected results from the XENON1T experiment, deep below Italy's Apennine Mountains.

  • Astronomers solve 900-year-old cosmic mystery surrounding Chinese supernova of 1181AD
    15 September 2021, 3:54 pm
    A 900-year-old cosmic mystery surrounding the origins of a famous supernova first spotted over China in 1181AD has finally been solved, according to an international team of astronomers. New research says that a faint, fast expanding cloud (or nebula), called Pa30, surrounding one of the hottest stars in the Milky Way, known as Parker's Star, fits the profile, location and age of the historic supernova.

  • Shining a light on Moon’s oldest geologic imprints
    14 September 2021, 4:00 pm
    New research has found the Moon may have been subjected to much greater impacts from asteroids and other bodies than previously thought, building on our understanding of the Moon's earliest geologic evolution.

  • Affordable housing in outer space: Scientists develop cosmic concrete from space dust and astronaut blood
    13 September 2021, 7:57 pm
    Transporting a single brick to Mars can cost more than a million British pounds -- making the future construction of a Martian colony seem prohibitively expensive. Scientists have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.

  • Astronomers spot the same supernova three times -- and predict a fourth sighting in 16 years
    13 September 2021, 7:56 pm
    An enormous amount of gravity from a cluster of distant galaxies causes space to curve so much that light from them is bent and emanated our way from numerous directions. This 'gravitational lensing' effect has allowed astronomers to observe the same exploding star in three different places in the heavens. They predict that a fourth image of the same explosion will appear in the sky by 2037. The study provides a unique opportunity to explore not just the supernova itself, but the expansion of our universe.

  • Largest virtual universe free for anyone to explore
    10 September 2021, 6:16 pm
    An international team of researchers developed the largest and most detailed simulation of the Universe to date and has made it freely available on the cloud to everyone. This simulation, named Uchuu, will help astronomers to interpret results from Big Data galaxy surveys.

  • ESO captures best images yet of peculiar 'dog-bone' asteroid
    9 September 2021, 6:38 pm
    Astronomers have obtained the sharpest and most detailed images yet of the asteroid Kleopatra. The observations have allowed the team to constrain the 3D shape and mass of this peculiar asteroid, which resembles a dog bone, to a higher accuracy than ever before. Their research provides clues as to how this asteroid and the two moons that orbit it formed.

  • Surprise: The Milky Way is not homogeneous
    9 September 2021, 12:06 am
    In order to better understand the history and evolution of the Milky Way, astronomers are studying the composition of the gases and metals that make up an important part of our galaxy. Three main elements stand out: the initial gas coming from outside our galaxy, the gas between the stars inside our galaxy -- enriched with chemical elements --, and the dust created by the condensation of the metals present in this gas. Until now, theoretical models assumed that these three elements were homogeneously mixed throughout the Milky Way and reached a level of chemical enrichment similar to the Sun's atmosphere, called the Solar metallicity. Today, a team of astronomers demonstrates that these gases are not mixed as much as previously thought, which has a strong impact on the current understanding of the evolution of galaxies. As a result, simulations of the Milky Way's evolution will have to be modified.

  • Hydrogen-burning white dwarfs enjoy slow aging
    6 September 2021, 5:13 pm
    Could dying stars hold the secret to looking younger? New evidence suggests that white dwarfs could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters.

  • Astronomers explain origin of elusive ultradiffuse galaxies
    6 September 2021, 5:13 pm
    As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. An international team of astronomers reports it has used sophisticated simulations to detect a few 'quenched' UDGs in low-density environments in the universe. A quenched galaxy is one that does not form stars.

  • Stellar collision triggers supernova explosion
    2 September 2021, 11:46 pm
    The Very Large Array Sky Survey gave astronomers the first clue that ultimately revealed a dramatic story -- the remnant of a star that exploded long ago had plunged into the core of its companion star causing it, too, to explode as a supernova.

  • Geologists propose theory about a famous asteroid
    1 September 2021, 6:41 pm
    Vesta, like Earth, is composed of rock in its crust and mantle, and it has an iron core. Therefore, studying Vesta helps us understand the very early days of our planetary neighborhood and how our own planet formed.

  • Cold planets exist throughout our galaxy, even in the galactic bulge, research suggests
    30 August 2021, 8:02 pm
    Researchers combined observations and modeling to infer the distribution of cold planets in the Milky Way. The results suggest that this distribution is not strongly dependent on the distance from the galactic center. Cold planets seem to be present throughout our galaxy, even in the galactic bulge, where their existence was uncertain. The findings could improve our understanding of both planetary formation and its history in the Milky Way.

  • New mathematical solutions to an old problem in astronomy
    30 August 2021, 6:32 pm
    The Bernese theoretical astrophysicist Kevin Heng has achieved a rare feat: On paper, he has derived novel solutions to an old mathematical problem needed to calculate light reflections from planets and moons. Now, data can be interpreted in a simple way to understand planetary atmospheres, for example. The new formulae will likely be incorporated into future textbooks.
