Stephen Hawking's boffin buds buy HPE HPC to ogle universe

Well, would ya look at that? Hewlett Packard Enterprise has retained a customer. Stephen Hawking's Centre for Theoretical Cosmology (COSMOS) has slurped the firm's latest data-crunching HPC system to better understand the universe. The Superdome Flex server was deployed eight days ago at the unit, part of the University of …

Let's grow a baby universe in a supercomputer, watch black holes collide

Physicists have created simulations that predict the rate at which gravitational waves from the collision of monstrous supermassive black holes may be detected. The results are due to be announced later today at the Royal Astronomical Society's National Astronomy Meeting. In a monumental discovery, gravitational waves were …

Beautiful model to explain the universe to physicists

An international team of cosmologists has made the first step towards creating the most accurate ever model of the universe by simulating Einstein’s field equations, according to recent research published in Physical Review Letters. Computer simulations are vital in cosmology and allow scientists to study and test theories …

What did you see, Elder Galaxies? What made you age so quickly?

A group of astronomers has spotted 15 massive galaxies that were already mature just 1.6 billion years after the Big Bang. At that age, galaxies should be youthful entities, still gathering dust and gasses into stars. These 15, on the other hand, as observed today, were grown-ups filled with old stars and exhibited a lack of …

Indestructible Death Stars blow up planets with glowing KILL RAY

Pics Move over, Lord Vader. A group of astroboffins using Chile's high-desert Atacama Large Millimeter/submillimeter Array (ALMA) have peered into the Orion Nebula's planetary nursery and discovered that massively powerful stars can be so intense that they blow away any chance of planets forming around new stars being born in their …

Top comet-watcher pens ISON's emotional obituary

Comet-connoisseur Karl Battams of the Naval Research Laboratory has released a heartfelt – and more than a little tongue-in-cheek – eulogy for Comet C/2012 S1, aka ISON, which suffered a fiery death last Thursday when it was roasted, toasted, melted, and smelted by our merciless Sun. Comet ISON 'This is how comet C/2012 S1 ( …

Cosmic blast mystery solved in neutron star's intense death throes

A pair of European astrophysicists believe they've solved the mystery of exceedingly bright, never-repeated flashes of radio waves that come to us from the distant past. The source of those brief, intense flashes can be defined in two ways, depending upon whether you'd prefer to look at the event as a death or a birth. "We …

Big Bang bashing boffins ‘Big Bounce’ back to BIRTH OF TIME

A group of Penn State physicists says the universe we now see could have arisen from a "Big Bounce" rather than a Big Bang. The new work by Penn State, led by professor Abhay Ashtekar, director of the Institute for Gravitation and the Cosmos, proposes ways to apply quantum physics "further back in time than ever before – right …

Your brain, the Internet and the Universe

Correlation does not imply causation. However, some correlations are at least fascinating, and here’s one that’s getting a lot of attention: the apparent structural similarity between the growth of the universe, that of the human brain, and complex artificial networks like the Internet or Twitter. In fact, according to the …

Revealed at last: Universe's intergalactic dark matter skeleton

Higgs, Schmiggs... When that infinitesimal speck was sucking up all the journalistic oxygen on Independence Day, another momentous scientific discovery was also being announced: the first observation of filaments of dark matter, the stuff that forms the "skeleton" of our universe. Invisible, inexplicable dark matter makes up …

Astroboffin says 'black holes murder galaxies'

About 25,000 light years from earth, nestled in the center of our galaxy, lurks a supermassive black hole. Luckily for us, our galaxy's matter-sucking hub is far less active than those at the core of many other galaxies. If it weren't, we'd all be dead. Or, more likely, our earth would never have come to be in the first place …
