Dark Matter Hinted at Again at Cresst Experiment
physburn writes “The BBC is reporting recent results from the Cresst dark matter search in Italy. Between 2009 and 2011, Cresst have seen 67 events, a 4 sigma detection of dark matter particles with a mass of either around 15 GeV or 25 GeV. The results… Continue reading
Reconsidering The Moon
Throughout the ages, man has tried to better understand our closest celestial neighbor through myths and science. Our knowledge of the moon has changed over and over again as we learn more and more about the crater-covered satellite. And research is st… Continue reading

What’s so scandalous about a naked singularity? [Ask A Physicist]
The centers of black holes are among the strangest places in the universe — so strange that current physics can't even describe them. Could these singularities be found out in the open? In this week's "Ask a Physicist" we find out…. Continue reading

Black holes may have been fundamental building blocks of the early universe [Cosmology]
Most astronomers agree that at the center of every galaxy lies a supermassive black hole. But how did these gravitational monsters form? Now it seems that they may have been here since the beginning of time.
At least, they’ve been here as long as the… Continue reading

Massive eruption on the sun yesterday means a solar storm zooming by Earth tomorrow [Video]
This picture was taken by a NASA solar observatory yesterday, and it shows one of the biggest explosions we’ve ever seen on the sun. For perspective, look at the upper left corner. There’s a little circle the size of Earth.
The explosion dwarfs our pl… Continue reading

NASA: Japan quake appears to have shortened Earth days, shifted axis
NASA reports that the March 11, magnitude 9.0 earthquake in Japan may have shortened the length of each Earth day by about 1.8 microseconds and shifted its figure axis by about 17 centimeters . “But don’t worry–you won’t notice the difference,” and “c… Continue reading

Pasta-Shaped Light From Spinning Black Holes Could Challenge Einstein
Rotating black holes could leave a twisty signature on light escaping their gravitational maws. If this screwy light can be detected from Earth, it would give astronomers a new way to detect exotic black holes and a new test of Einstein’s theory of … Continue reading

No one can escape friction, not even in a vacuum. [Physics]
On earth, we’re slowed down by the muck of the everyday world. Matter slows us down, rubbing against us and taking away our speed and power. Gravel, air, even slip-n-slides, exert some friction on us. This frictional force runs counter to our motion, a… Continue reading

The universe is at least 250 times bigger than it looks [Cosmology]
The universe is so unimaginably large that parts of it are literally impossible to see, because their light is too distant to reach us even after 14 billion years. Now we might know just how big the cosmos really is. Turns out everything we can see is … Continue reading

What Exactly Is a Galaxy?
sciencehabit writes "Surprising as it may sound, astronomers don't have an answer to this basic question. There's no agreement on when a collection of stars stops being a cluster and starts being something more. Now, in an echo of the rece… Continue reading
Particles can be quantum entangled through time as well as space [Mad Science]
Quantum entanglement says that two particles can become intertwined so that they always share the same properties, even if they’re separated in space. Now it seems particles can be entangled in time, too. Who’s ready for some serious quantum weirdness?… Continue reading

The forgotten genius who discovered black holes over 200 years ago [Secret History]
Centuries before black holes became accepted science, a fat little man in 1780s Yorkshire imagined stars so massive that even light could not escape. He predicted black holes. This is the incredible story of John Michell and his “dark stars.”The Fat Li… Continue reading

Cosmic strings are super-massive, ultra-thin cracks in the universe [Mad Astrophysics]
Cosmic strings are theoretical fault lines in the universe, defective links between different regions of space created in the moments after the Big Bang. And they might be theoretical no longer – distant quasars show the fingerprints of these strings.C… Continue reading
