  • Waves in Saturn's rings give precise measurement of planet's rotation rate
    18 January 2019, 6:30 pm
    Saturn's distinctive rings were observed in unprecedented detail by NASA's Cassini spacecraft, and scientists have now used those observations to probe the interior of the giant planet and obtain the first precise determination of its rotation rate. The length of a day on Saturn, according to their calculations, is 10 hours 33 minutes and 38 seconds.

  • Saturn hasn't always had rings
    17 January 2019, 8:21 pm
    In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists have now used these measurements to determine the mass of the rings and estimate its age, which is young: 10-100 million years. This supports the hypothesis that the rings are rubble from a comet or Kuiper Belt object captured late in Saturn's history.

  • Scientists find increase in asteroid impacts on ancient Earth by studying the Moon
    17 January 2019, 8:20 pm
    A team of scientists has determined the number of asteroid impacts on the Moon and Earth increased by two to three times starting around 290 million years ago. Previous theories held that there were fewer craters on both objects dating back to before that time because they had disappeared due to erosion. The new findings claim that there were simply fewer asteroid impacts during that earlier period.

  • High-speed supernova reveals earliest moments of a dying star
    16 January 2019, 8:06 pm
    An international team of researchers found evidence for the much theorized 'hot cocoon'.

  • Evidence of changing seasons, rain on Saturn's moon Titan's north pole
    16 January 2019, 5:55 pm
    An image from the international Cassini spacecraft provides evidence of rainfall on the north pole of Titan, the largest of Saturn's moons. The rainfall would be the first indication of the start of a summer season in the moon's northern hemisphere.

  • New way supermassive black holes are 'fed'
    14 January 2019, 7:09 pm
    A new study finds that some supermassive black holes are 'triggered' to grow, suddenly devouring a large amount of gas in their surroundings.

  • Double star system flips planet-forming disk into pole position
    14 January 2019, 5:42 pm
    Astronomers have found the first confirmed example of a double star system that has flipped its surrounding disc to a position that leaps over the orbital plane of those stars.

  • Birth of a black hole or neutron star captured for first time
    11 January 2019, 12:47 am
    After combining several imaging sources, including hard X-rays and radiowaves, a team now speculates that the telescopes captured the exact moment a star collapsed to form a compact object, such as a black hole or neutron star. The stellar debris, approaching and swirling around the object's event horizon, caused The Cow's remarkably bright glow.

  • Astronomers find signatures of a 'messy' star that made its companion go supernova
    10 January 2019, 10:09 pm
    Astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode. Through repeated observations of SN 2015cp, a supernova 545 million light years away, the team detected hydrogen-rich debris that the companion star had shed prior to the explosion.

  • Cosmic telescope zooms in on the beginning of time
    10 January 2019, 2:27 pm
    Observations from Gemini Observatory identify a key fingerprint of an extremely distant quasar, allowing astronomers to sample light emitted from the dawn of time. Astronomers happened upon this deep glimpse into space and time thanks to a foreground galaxy acting as a gravitational lens, which magnified the ancient light. The Gemini observations provide critical pieces of the puzzle in confirming this object as the brightest appearing quasar so early in the history of the universe.

  • X-ray pulse detected near event horizon as black hole devours star
    10 January 2019, 12:47 am
    New findings are the first demonstration of a tidal disruption flare being used to estimate a black hole's spin.

  • Long-duration space missions have lasting effects on spinal muscles
    9 January 2019, 11:06 pm
    Astronauts who spend several months on the International Space Station have significant reductions in the size and density of paraspinal muscles of the trunk after returning to Earth, reports a new study.

  • The lonely giant: Milky Way-sized galaxy lacking galactic neighbors
    9 January 2019, 11:06 pm
    Long ago in a galaxy far, far away, fewer galaxies were born than expected -- and that could create new questions for galaxy physics, according to a new study.

  • Canada's CHIME telescope detects second repeating fast radio burst
    9 January 2019, 8:27 pm
    Scientists have found the second repeating fast radio burst (FRB) ever recorded. The discovery of the extragalactic signal is among the first, eagerly awaited results from the Canadian Hydrogen Intensity Mapping Experiment (CHIME). The repeating FRB was one of a total of 13 bursts detected over a period of just three weeks during the summer of 2018, while CHIME was in its pre-commissioning phase.

  • Astronomers observe evolution of a black hole as it wolfs down stellar material
    9 January 2019, 8:26 pm
    On March 11, an instrument aboard the International Space Station detected an enormous explosion of X-ray light that grew to be six times as bright as the Crab Nebula, nearly 10,000 light years away from Earth. Scientists determined the source was a black hole caught in the midst of an outburst -- an extreme phase in which a black hole can spew brilliant bursts of X-ray energy as it devours an avalanche of gas and dust from a nearby star.

  • The plants that China sprouted on the Moon have died
    18 January 2019, 1:00 pm
    Dead plants Earlier this month, an experiment on China’s Chang’e 4 lander got cotton plants to sprout on the Moon, a historic first. Well, they’re already dead. On Jan. 7, China’s space agency released pictures of cotton seeds beginning to grow on the Chang’e 4 lander. But, as reported by GBTimes on Jan. 16, the new sprouts haven’t survived the freezing temperatures on the lunar surface, even in their protective capsule. The cotton seeds sprouted inside of a c

  • Our solar system's formation was a lot messier than you think
    16 January 2019, 1:00 pm
    When most of us learn about the solar system, it seems like a pretty well-ordered place. Our Sun formed first, about five billion years ago, and the planets appeared a little later. As a very general trend, these planets grew larger and less dense the farther from the Sun they formed. But this story leaves out the chaotic dynamics and frenetic reshuffling that occurred when our solar system was young. Nature may like order eventually, but that order evolves out of pure chance. Our solar system

    15 January 2019, 1:00 pm
    Near-Earth asteroid 433 Eros makes its closest approach to Earth since 2012 today, when it comes within 19.4 million miles (31.2 million kilometers) of our planet. Throughout the week, asteroid Eros glows at 9th magnitude, making it bright enough to glimpse through small telescopes. The elongated asteroid has an average diameter of just over 10.5 miles (17 km), making it about 1/50th the diameter of dwarf Planet Ceres, which is the largest body in the asteroid belt. Asteroid 433 Eros resides

  • Chang'e 4 sends another trove of images from the Moon's far side

  • Hubble takes second-most detailed image ever
    11 January 2019, 1:00 pm
    Hubble just released its second-largest image ever: the Triangulum Galaxy, and it’s a stunner. While Andromeda has been holding the top spot since being imaged back in 2015, this zoomable, roughly 665 million-pixel composite is nothing to sneeze at, clocking in at a staggering 34,372 x 19,345 pixels. All told that adds up to 665 million pixels. Also known as Messier 33, 40 billion stars make up this spiral galaxy, which is faintly visible by naked eye under a dark sky as a small smudge in
