    NASA spots signs of 22-MILE-WIDE crater buried beneath Greenland ice sheet in what could be evidence of another ancient impact in the region

    • Researchers say they've found what could be a 22-mile-wide impact crater
    • Bowl-shaped depression found in northwest Greenland, 114miles from Hiawatha
    • Scientists announced 19-mile-wide impact crater under Hiawatha Glacier in Nov
    • The Hiawatha crater was the first crater ever to be found beneath Earth's ice

    Scientists have discovered what could be a 22-mile-wide impact crater buried deep beneath Greenland’s ice.

    If so, it would be the second such discovery announced in the last few months.

    A NASA glaciologist spotted signs of the possible crater in northwest Greenland just 114 miles from the recently-discovered crater beneath the Hiawatha Glacier while scouring satellite imagery and topographic maps of the area.

    Exactly how and when it formed still remain a mystery, though the researchers suspect it may be more than 80,000 years old.
    ...
    The suspected crater is estimated to be 22.7 miles wide.

    According to the team, it would be the 22nd largest impact crater known on Earth, if it really turns out to be one.

    ‘The only other circular structure that might approach this size would be a collapsed volcanic caldera,’ MacGregor said.

    ‘But the areas of known volcanic activity in Greenland are several hundred miles away. Also, a volcano should have a clear positive magnetic anomaly, and we don’t see that at all.’

    Though the new crater sits just 114 miles from the one announced in November, the researchers say they don’t appear to have formed at the same time.
    ...
    The ice in the area is at least 79,000 years old, the team says.

    If this really is an impact crater, the researchers say it either happened more than 79,000 years ago, or, if it was more recently, all of the ice from the time eroded.

    ‘The ice layers above this second crater are unambiguously older than those above Hiawatha, and the second crater is about twice as eroded,’ MacGregor said.
    ....
    ‘This does not rule out the possibility that the two new Greenland craters were made in a single event, such as the impact of a well separated binary asteroid, but we cannot make a case for it either,’ said William Bottke, a planetary scientist with the Southwest Research Institute in Boulder, Colorado.

    ‘The existence of a third pair of unrelated craters is modestly surprising but we don’t consider it unlikely,’ MacGregor said.

    ‘On the whole, the evidence we’ve assembled indicates that this new structure is very likely an impact crater, but presently it looks unlikely to be a twin with Hiawatha.’

    This Is the Oldest Age You Can Possibly Live To (According to Science)

    ...
    Human life expectancies have gone up over the years. But, according to new research, our average maximum age ceiling hit a plateau decades ago.

    It’s no secret that humans have gotten really good at living longer. We know to eat right, to exercise, to take our vitamins, and to get our nightly eight hours. (And that doesn’t even account for the striding advancements modern medicine has made.) But no matter how smart way go about our quest for immortality, there’s only so far we can go.

    According to a new study published in Nature—led by John Einmahl of Tilburg University and Laurens de Haan of the Erasmus University Rotterdam—the human “age ceiling” is approximately 114.1 years for men and 115.7 years for women. (The discrepancy between the genders could be explained by the fact that testosterone has been linked to shorter lifespans.)
    ...
    As of this writing, Einmahl and de Haan’s research has yet to be peer-reviewed, but its findings appear to be bolstered by a similar study from last year: Researchers at the Albert Einstein College of Medicine found that the average maximum age is 115.

    Something Else Instead of Planet Nine Could Be Hiding in The Outer Solar System

    ....
    MICHELLE STARR
    21 JAN 2019




    Somewhere in the outer reaches of the Solar System, beyond the orbit of Neptune, something wonky is happening. A few objects are orbiting differently from everything else, and we don't know why.



    A popular hypothesis is that an unseen object called Planet Nine could be messing with these orbits; astronomers are avidly searching for this planet. But now physicists have come up with an alternative explanation they think is more plausible.

    Instead of one big object, the orbital wobblies could be caused by the combined gravitational force of a number of smaller Kuiper Belt or trans-Neptunian objects (TNOs). That's according to astrophysicists Antranik Sefilian of the University of Cambridge in the UK and Jihad Touma of the American University of Beirut in Lebanon.

    If it sounds familiar, that's because Sefilian and Touma are not the first to think of this idea - but their calculations are the first to explain significant features of the strange orbits of these objects, while taking into account the other eight planets in the Solar System.

    A hypothesis for Planet Nine was first announced in a 2016 study. Astronomers studying a dwarf planet in the Kuiper Belt noticed that several TNOs were "detached" from the strong gravitational influence of the Solar System's gas giants, and had weird looping orbits that were different from the rest of the Kuiper Belt.

    But the orbits of these six objects were also clustered together in a way that didn't appear random; something seemed to have tugged them into that position. According to modelling, a giant, heretofore unseen planet could do so.

    So far, this planet has remained elusive - not necessarily odd, since there are considerable technical challenges to seeing a dark object that far away, especially when we don't know where it is. But its evasiveness is prompting scientists to seek alternative explanations.

    "The Planet Nine hypothesis is a fascinating one, but if the hypothesised ninth planet exists, it has so far avoided detection," Sefilian said, adding that the team wanted to see if there was a less dramatic explanation of the weird TNO orbits.

    Earth is missing a huge part of its crust. Now we may know why.

    ...
    The Grand Canyon is a gigantic geological library, with rocky layers that tell much of the story of Earth’s history. Curiously though, a sizeable layer representing anywhere from 250 million years to 1.2 billion years is missing.

    Known as the Great Unconformity, this massive temporal gap can be found not just in this famous crevasse, but in places all over the world. In one layer, you have the Cambrian period, which started roughly 540 million years ago and left behind sedimentary rocks packed with the fossils of complex, multicellular life. Directly below, you have fossil-free crystalline basement rock, which formed about a billion or more years ago.

    So where did all the rock that belongs in between these time periods go? Using multiple lines of evidence, an international team of geoscientists reckons that the thief was Snowball Earth, a hypothesized time when much, if not all, of the planet, was covered in ice.

    According to the team, at intervals within those billion or so years, up to a third of Earth’s crust was sawn off by Snowball Earth’s roaming glaciers and their erosive capabilities. The resulting sediment was dumped into the slush-covered oceans, where it was then sucked into the mantle by subducting tectonic plates. (Here’s what will happen when Earth’s tectonic plates grind to a halt.)

    Effectively, in many locations, Earth buried the evidence of about a fifth of its geological history, the team argues today in the Proceedings of the National Academy of Sciences. The notion is elegant but provocative, and the authors themselves predict that some geoscientists will express skepticism.
