Powerful, radio-wavelength laser light has been detected emanating from the greatest distance across deep space yet. It's a type of massless cosmic object called a megamaser, and its light has traveled for a jaw-dropping 5 billion light-years to reach us here on Earth. The astronomers who discovered it using the MeerKAT radio telescope in South Africa have named it Nkalakatha – an isiZulu word meaning "big boss". The discovery has been accepted into The Astrophysical Journal Letters and is available on preprint server arXiv. "It's impressive that, with just a single night of observations, we've already found a record-breaking megamaser,"...

Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light waves for which this does not apply: for any specific disordered medium—such as the sugar cube you may just have put in your coffee—tailor-made light beams can be constructed that are practically not changed by this medium, but only attenuated. The light beam penetrates the medium, and a light pattern...

These are some of the movie clips I have found related with directed energy weapons. If you are interested in weapons or technology, these are some fantastic movie clips to enjoy with. I have been collecting these on my own and thought to share it with others. There were some systems that I could not find with any movie clips, which I will leave links of the articles related to those in my comment.

The gun uses a large dish mounted on a Humvee vehicle The US military has given the first public display of what it says is a revolutionary heat-ray weapon to repel enemies or disperse hostile crowds. The gun - called Silent Guardian - projects an invisible high energy beam that produces a sudden burning feeling, but is actually harmless. The beam can be fired as far as 500m (550 yards), much further than existing non-lethal weapons like rubber bullets. The gun should be in use by the US military within three years. The prototype weapon uses a large rectangular...

MOODY AIR FORCE BASE, Georgia (Reuters) - The U.S. Defense Department on Wednesday unveiled what it called a revolutionary heat-beaming weapon that could be used to control mobs or repel foes in conflicts like Iraq and Afghanistan. The so-called Active Denial System causes an intense burning sensation causing people to run for cover, but no lasting harm, officials said. "This is a breakthrough technology that's going to give our forces a capability they don't now have," Theodore Barna, an assistant deputy undersecretary of defense for advanced systems and concepts, told Reuters. "We expect the services to add it to their...

MOON DAILYBig Bang Afterglow Fails An Intergalactic Shadow Test Because it is seen coming from every direction in nearly uniform power and frequency, cosmologists theorized that the microwave background is afterglow radiation left over by the Big Bang that created the universe. by Staff Writers Huntsville AL (SPX) Sep 03, 2006 The apparent absence of shadows where shadows were expected to be is raising new questions about the faint glow of microwave radiation once hailed as proof that the universe was created by a "Big Bang." In a finding sure to cause controversy, scientists at The University of Alabama in...
