  • Worldwide coordinated search for dark matter

    An international team of researchers has published comprehensive data on the search for dark matter using a worldwide network of optical magnetometers. According to the scientists, dark matter fields should produce a characteristic signal pattern that can be detected  by correlated measurements at multiple stations of the GNOME network.
  • Satellites reveal world's most famous 'mega iceberg' released 152 billion tons of fresh water into ocean as it scraped past South Georgia

    Scientists monitoring the giant A68A Antarctic iceberg from space reveal that a huge amount of fresh water was released as it melted around the sub-Antarctic island of South Georgia. 152 billion tonnes of fresh water -- equivalent to 20 x Loch Ness or 61 million Olympic sized swimming pools, entered the seas around the sub-Antarctic island of South Georgia when the megaberg A68A melted over 3 months in 2020/2021, according to a new study.
  • Hubble finds a black hole igniting star formation in a dwarf galaxy

    Often portrayed as destructive monsters that hold light captive, black holes take on a less villainous role in the latest research from NASA's Hubble Space Telescope. A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up. The black hole is apparently contributing to the firestorm of new star formation taking place in the galaxy. The dwarf galaxy lies 30 million light-years away, in the southern constellation Pyxis.
  • How many black holes are out there in the universe?

    A new study has investigated stellar mass black holes, which are black holes with masses between a few to some hundred solar masses, that originated at the end of the life of massive stars. According to the study, a remarkable amount of around 1 percent of the overall ordinary matter of the universe is locked up in stellar mass black holes. Astonishingly, the researchers have found that the number of black holes within the observable universe at present time is about about 40 times 10 to the exponent 18.
  • Internal ocean in small Saturn moon uncovered

    A scientist recently set out to prove that the tiny, innermost moon of Saturn was a frozen inert satellite and instead discovered compelling evidence that Mimas has a liquid internal ocean. In the waning days of NASA's Cassini mission, the spacecraft identified a curious libration, or oscillation, in the moon's rotation, which often points to a geologically active body able to support an internal ocean.
  • Newly discovered carbon may yield clues to ancient Mars

    NASA's Curiosity rover landed on Mars on Aug. 6, 2012, and since then has roamed Gale Crater taking samples and sending the results back home for researchers to interpret. Analysis of carbon isotopes in sediment samples taken from half a dozen exposed locations, including an exposed cliff, leave researchers with three plausible explanations for the carbon's origin -- cosmic dust, ultraviolet degradation of carbon dioxide, or ultraviolet degradation of biologically produced methane.
  • Being in space destroys more red blood cells

    A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a new study.
  • New study shows novel crystal structure for hydrogen under high pressure

    Being the first element to form, hydrogen holds clues about the distribution of matter in our universe. Normally a gas, hydrogen exists as a solid under ultra-high-pressure conditions commonly found in the core of giant gaseous planets. However, the structures of solid hydrogen have remained elusive owing to difficulties in replicating such conditions experimentally. Now, a new study sheds light on this aspect using simulations and data science methods.
  • Unusual team finds gigantic planet hidden in plain sight

    An astronomer and a group of eagle-eyed citizen scientists have discovered a giant gas planet hidden from view by typical stargazing tools.
  • Newly-found planets on the edge of destruction

    Astronomers have found three Jupiter-like exoplanets that are dangerously close to being 'swallowed up' by their host stars. The discovery gives new insight into how planetary systems evolve over time, helping to reveal the fate of solar systems like our own.
  • Martian meteorite’s organic materials origin not biological, formed by geochemical interactions between water and rock

    Organic molecules found in a meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago, according to new analysis.
  • New insights into seasons on a planet outside our solar system

    Imagine being in a place where the winds are so strong that they move at the speed of sound. That's just one aspect of the atmosphere on XO-3b, one of a class of exoplanets (planets outside our solar system), known as hot Jupiters. The eccentric orbit of the planet also leads to seasonal variations hundreds of times stronger than what we experience on Earth.
  • New explanation for Moon’s half-century magnetic mystery

    A new study reveals how the diminutive Moon could have been an occasional magnetic powerhouse early in its history, a question that has confounded researchers since NASA's Apollo program began in the 1960s.
  • ALMA catches 'intruder' redhanded in rarely detected stellar flyby event

    Scientists made a rare detection of a likely stellar flyby event in the Z Canis Majoris (Z CMa) star system. An intruder -- not bound to the system -- object came in close proximity to and interacted with the environment surrounding the binary protostar, causing the formation of chaotic, stretched-out streams of dust and gas in the disk surrounding it.
  • 'Slushy' magma ocean led to formation of the Moon’s crust

    Scientists have shown how the freezing of a 'slushy' ocean of magma may be responsible for the composition of the Moon's crust.
  • Cosmic 'spider' found to be source of powerful gamma-rays

    Astronomers have discovered the first example of a binary system where a star in the process of becoming a white dwarf is orbiting a neutron star that has just finished turning into a rapidly spinning pulsar. The pair is a 'missing link' in the evolution of such binary systems.
  • Oxygen ions in Jupiter's innermost radiation belts

    Researchers find high-energy oxygen and sulfur ions in Jupiter's inner radiation belts -- and a previously unknown ion source.
  • New theory finds upcoming satellite mission will be able to detect more than expected

    Researchers have theorized that in addition to the gravitational waves originating from vacuum fluctuations during inflation, a large amount of gravitational waves can be sourced by the quantum vacuum fluctuations of additional fields during inflation.
  • 1,000-light-year wide bubble surrounding Earth is source of all nearby, young stars

    The Earth sits in a 1,000-light-year-wide void surrounded by thousands of young stars -- but how did those stars form? For the first time, astronomers have retraced the history of our galactic neighborhood, showing exactly how the young stars nearest to our solar system formed.
  • Newly discovered type of 'strange metal' could lead to deep insights

    A new discovery could help scientists to understand 'strange metals,' a class of materials that are related to high-temperature superconductors and share fundamental quantum attributes with black holes.
  • Rugby ball-shaped exoplanet discovered

    With the help of the CHEOPS space telescope, an international team was able to detect the deformation of an exoplanet for the first time. Due to strong tidal forces, the appearance of the planet WASP-103b resembles a rugby ball rather than a sphere.
  • New evidence of a gravitational wave background

    The results of a comprehensive search for a background of ultra-low frequency gravitational waves has been announced by an international team of astronomers.
  • Black hole at center of Milky Way unpredictable and chaotic

    Researchers have found that the black hole at the center of our galaxy, Sagittarius A*, not only flares irregularly from day to day but also in the long term.
  • New treasure trove of globular clusters holds clues about galaxy evolution

    Using observations of Centaurus A, a nearby elliptical galaxy, obtained with the Gaia space telescope and ground-based instruments under the PISCeS survey, a team of astronomers presents an unprecedented number of globular cluster candidates in the outer regions of the galaxy. The findings provide astronomers with an even more detailed picture of galactic architecture and history of collisions and mergers.
  • Twelve for dinner: The Milky Way’s feeding habits shine a light on dark matter

    Astronomers are one step closer to revealing the properties of dark matter enveloping our Milky Way galaxy, thanks to a new map of twelve streams of stars orbiting within our galactic halo.
