Milky Way Is a 'Galactic Lightweight'

Same-sized neighbor Andromeda has twice the mass

(Newser) - If our galaxy were a boxer, it would have just slipped down a few weight classes—and would be no match for our neighbor Andromeda. New research has revealed that the Milky Way, while still mind-bogglingly vast, is only around half the weight of the Andromeda galaxy, which is about... More »

How Dark Matter Could End Life on Earth

By hurling comets at our planet: Harvard study

(Newser) - Dark matter seems to hold galaxies snugly together across the universe—but it could also hurl comets at Earth and threaten our entire species, according to a new study . This is based on a theory that there's a huge disk of dark matter lying on the central plane of... More »

Dark Matter's 'Cosmic Web' Spotted for 1st Time

Scientists see glue that holds universe together

(Newser) - Scientists have seen a tendril of dark matter for the first time, and all it took was a "cosmic flashlight." Using the Keck telescope in Hawaii, a scientific team spotted the dark matter in a gas cloud illuminated by the radiation of a distant quasar, the BBC reports.... More »

Secret to Dark Matter May Lie Under South Dakota

Large Underground Xenon experiment to be housed in town of Lead

(Newser) - Nestled nearly 5,000 feet beneath the Earth in the gold boom town of Lead, South Dakota, is a laboratory that could help scientists answer some pretty heavy questions about life, its origins, and the universe. Today part of the Homestake Gold Mine—opened in 1876 and shuttered in 2003—... More »

Experiment Proves Einstein Right About Universe

It's expanding just how he said it should

(Newser) - A new experiment has proven another of Einstein's theories to be right on the money. Einstein's general theory of relativity predicts the speed at which galaxies move toward each other and the rate at which the universe is expanding. A team of cosmologists recently measured a slice of... More »

Dark Matter Map Unveils Cosmic Mystery

Data from Hubble telescope reaches back billions of years

(Newser) - Invisible matter may be holding us all together after all. Researchers have unveiled the biggest-ever map of dark matter in the universe, which shows large clumps and wispy filaments of the stuff nestling galaxies like jewels, the BBC and Space.com report. "We've seen the first glimpse of... More »

Hunt for Dark Matter Heads Deeper Underground

Scientist to seek WIMPs at site more than a mile deep

(Newser) - Scientists hunting for the invisible substance believed to make up most of the matter in the universe are planning to move the search to a two-mile-deep mine in Canada. Researchers trying to detect dark matter about a half-mile below the surface of Minnesota suspect they may have captured two particles... More »

Large Hadron Collider Closing Down for a Year

Atom-smasher needs months of work to run at full capacity

(Newser) - The glitch-plagued Large Hadron Collider will be closing down for a year at the end of 2011 to fix flaws in its construction. The atom-smasher restarted recently after being out of commission for 14 months and will soon accelerate protons to energies of 7 trillion electron volts. It will take... More »

Dark Matter Particles Detected Deep in Mine

Astounding find may yield answers to universe mysteries

(Newser) - Scientists searching for traces of the mysterious substance believed to make up most of the universe's mass believe they have detected it for the first time at the bottom of an old mine in Minnesota.

New 'Petascale' Computers Will Speed Up Science

Machines accelerate advances in climate change, geology, drug development research

(Newser) - A new generation of "petascale" supercomputers capable of 1,000 trillion calculations per second—about twice the current standard—will start running next year, and the power could not only accelerate scientific discovery but also change the scientific method itself, the Washington Post reports. "We can now do... More »

Enormous Hole Found in Cosmos

Scientists spot unexpected void a billion light years wide

(Newser) - Astronomers have discovered a mysterious gigantic hole in the universe, reports Space.com. Unlike black holes, created by super dense material, this hole is devoid of matter. It measures nearly a billion light years wide and is 10 billion light years from earth. The hole was discovered by examining input... More »

Hubble Finds Dark Matter

(Newser) - Astronomers have discovered a ring of dark matter in a galaxy cluster about 5 billion light years away.
