  • Extreme exoplanet has a complex and exotic atmosphere

    An international team analyzed the atmosphere of one of the most extreme known planets in great detail. The results from this hot, Jupiter-like planet that was first characterized with the help of the CHEOPS space telescope, may help astronomers understand the complexities of many other exoplanets -- including Earth-like planets.
  • Cosmic physics mimicked on table-top as graphene enables Schwinger effect

    Researchers have succeeded in observing the so-called Schwinger effect, an elusive process that normally occurs only in cosmic events. By applying high currents through specially designed graphene-based devices, the team succeeded in producing particle-antiparticle pairs from a vacuum.
  • What wintering squirrels can teach astronauts

    The unique way that ground squirrels burn almost no energy when they hibernate -- with no loss of muscle mass -- has implications for space travel, biologists find.
  • Scientists explain mysterious finger-like features in solar flares

    Astronomers have presented a new explanation for the mysterious downward-moving dark voids seen in some solar flares.
  • Scientists make a new type of optical device using alumina

    Researchers have developed an alumina short-wavelength absorber patterned with moth eye-like structures. These new anti-reflective structures will improve the performance of telescopes studying radiation from the Big Bang.
  • Ancient ice reveals mysterious solar storm

    Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events.
  • Mysterious object unlike anything astronomers have seen before

    A team mapping radio waves in the universe has discovered something unusual that releases a giant burst of energy three times an hour, and it's unlike anything astronomers have seen before. Spinning around in space, the strange object sends out a beam of radiation that crosses our line of sight, and for a minute in every twenty, is one of the brightest radio sources in the sky.
  • Liquid water beneath Martian south polar cap?

    Scientists measured the properties of ice-brine mixtures as cold as -145 degrees Fahrenheit to help confirm that salty water likely exists between grains of ice or sediment under the ice cap at Mars' south pole. Laboratory measurements support oddly bright reflections detected by the MARSIS subsurface sounding radar aboard ESA's Mars Express orbiter.
  • Studying the Big Bang with artificial intelligence

    Artificial intelligence is being used for many extremely complex tasks. So why not use machine learning to study particle physics? As it turns out, this is not easy, because of some special mathematical properties of particle physics. But now, a neural network has been developed that can be used to study quark gluon plasma - the state of the universe after the Big Bang.
  • Extraordinary black hole found in neighboring galaxy

    At one hundred thousand solar masses, it is smaller than the black holes we have found at the centers of galaxies, but bigger than the black holes that are born when stars explode. This makes it one of the only confirmed intermediate-mass black holes, an object that has long been sought by astronomers.
  • New control technique uses solar panels to reach desired Mars orbit

    Aerospace engineers have developed a way to use articulated solar panels to steer the satellite during aerobraking, reducing the number of passes needed, resulting in potential savings in propellant, time, and money.
  • Hope for present-day Martian groundwater dries up in new study

    Liquid water previously detected under Mars' ice-covered south pole is probably just a dusty mirage, according to a new study of the Red Planet. The finding challenges a 2018 study that appeared to find liquid water under Mars' south polar cap.
  • Sidewinding young stellar jets spied by Gemini South

    Sinuous stellar jets meander lazily across a field of stars in new images. The gently curving stellar jets are the outflow from young stars, and astronomers suspect their sidewinding appearances are caused by the gravitational attraction of companion stars. These crystal-clear observations were made using the Gemini South telescope's adaptive optics system, which helps astronomers counteract the blurring effects of atmospheric turbulence.
  • Consistent asteroid showers rock previous thinking on Mars craters

    New research has confirmed the frequency of asteroid collisions that formed impact craters on Mars has been consistent over the past 600 million years.
  • Highly eccentric black hole merger discovered

    Scientists believe they have detected a merger of two black holes with eccentric orbits. This can help explain how some of the previous black hole mergers are much heavier than previously thought possible.
  • 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.
