Explanation: A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed image of the region includes cosmic sculptures made famous in Hubble Space Telescope close-ups of the starforming complex. Described as elephant trunks or Pillars of Creation, dense, dusty columns rising near the center are light-years in length but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars. Extending from the ridge of bright emission left of center...

Marine leaders have made the momentous recommendation to ditch the iconic M16 in favor of the M4 carbine as the new universal weapon for infantrymen. The recommendation to swap the venerated rifle that has served as the grunt’s primary implement of war since Vietnam now sits on the commandant’s desk, pending his final review and a decision. But, the swap appears imminent and if approved will relegate the M16 to a support role. It follows a similar shift already underway in the Army. With the endorsement of several major commands already supporting the switch — including Marine Corps Combat Development...

Marine Corps leaders have made the long-awaited proposal to adopt the M4 carbine as the standard Marine infantry rifle. The recommendation wouldn’t completely phase out the currently-standard M16, but it would push the archetypal rifle into a support role. This follows in the Army’s footsteps, which began the transition to M4s more than 20 years ago. The M4 is in use with the Marines for select roles and is issued to officers as well.

My nephew, Nick, had a BBC newscast on about human smugglers in Thailand.  It appears that the BBC is a bit less shy about showing weapons than many U.S. outlets, but that could simply be perception on this one show.  I watch very little TV.    From BBC.com: Manit told us his district had long been used by human traffickers to transfer migrants from boats to trucks. He wanted to stamp it out. But he was getting little help from the central government, or from local law enforcement.  The BBC correspondent was allowed to join a patrol off the coast. ...

I watch very little TV.  I do not like to corrupt the data flow.  But I happened to be in Las Vegas when my nephew was watching a BBC program on human smugglers in Thailand.  From BBC.com: Manit told us his district had long been used by human traffickers to transfer migrants from boats to trucks. He wanted to stamp it out. But he was getting little help from the central government, or from local law enforcement. The BBC correspondent was allowed to join a patrol off the coast.  In the video, the BBC is not shy about showing...

U.S. lawmakers recently questioned Army and Marine Corps leaders on small-arms and why the two services buy completely different bullets for the M16A4 rifles and M4 carbines. "You guys are using two different rounds, and you have procured several million rounds to date and you have used them in combat," Rep. Loretta Sanchez, D-Calif., said at a March 19 House Armed Services Committee hearing. Sanchez, the ranking member of the Subcommittee on Tactical Air and Land Forces, wanted to know why the Marine Corps uses the M855 5.56mm round and the Army uses the M855A1.

The U.S. Army is considering several upgrades to the M4A1 Carbine that could improve its accuracy and performance and change the weapon's appearance. Army weapons and contracting officials recently launched a market survey to see what the small-arms industry has to offer as far as better rails, triggers, charging handles and sights for the M4A1. "The government is seeking to procure M4A1-Plus (abbreviated as M4A1+) components as non-development items ... for improvements to the M4A1 Carbine," according to the March 13 document posted on FedBizOpps.gov. "It is anticipated that the M4A1+ components will be evaluated as a system. The system...

Explanation: The dust sculptures of the Eagle Nebula are evaporating. As powerful starlight whittles away these cool cosmic mountains, the statuesque pillars that remain might be imagined as mythical beasts. Pictured above is one of several striking dust pillars of the Eagle Nebula that might be described as a gigantic alien fairy. This fairy, however, is ten light years tall and spews radiation much hotter than common fire. The greater Eagle Nebula, M16, is actually a giant evaporating shell of gas and dust inside of which is a growing cavity filled with a spectacular stellar nursery currently forming an open...

A new view of the Eagle Nebula, one of the two largest and sharpest images Hubble Space Telescope has ever taken, is released by NASA for Hubble's 15th anniversary April 25, 2005. The new Eagle Nebula image reveals a tall, dense tower of gas being sculpted by ultraviolet light from a group of massive, hot stars. During the 15 years Hubble has orbited the Earth, it has taken more than 700,000 photos of the cosmos.

Explanation: To celebrate 25 years (1990-2015) of exploring the Universe from low Earth orbit, the Hubble Space Telescope's cameras were used to revisit its most iconic image. The result is this sharper, wider view of the region dubbed the Pillars of Creation, first imaged by Hubble in 1995. Stars are forming deep inside the towering structures. The light-years long columns of cold gas and dust are some 6,500 light-years distant in M16, the Eagle Nebula, toward the constellation Serpens. Sculpted and eroded by the energetic ultraviolet light and powerful winds from M16's cluster of young, massive stars, the cosmic pillars...

Embedded in these Eagle Nebula towers, which are sometimes called elephant trunks, are stars under creation. And in a short span of 20 years, you can see how the stars are slowly blowing the pillars apart. This is leading some press officials to call the structures “pillars of destruction.” And astronomers can chart how everything is changing over time. “I’m impressed by how transitory these structures are. They are actively being ablated away before our very eyes,” stated Paul Scowen of Arizona State University in Tempe, one of the astronomers who led the 1995 observations.

In 1995, the world was astonished by the image of a group of 4-light-year-tall columns located in the Eagle Nebula, 7,000 light years from here. So unimaginable it was that someone called them the Pillars of Creation. The only problem is that the pillars didn't really exist. Something had destroyed them more than a thousand years ago. It's a natural thought. Limited by our understanding of time, we look at objects in space as if they were mountains or the ocean. We genuinely perceive these stellar landscapes as something that is up there fixed, secure, rooted in our reality, the...

Explanation: From afar, the whole thing looks like an Eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed. In this cavity tall pillars and round globules of dark dust and cold molecular gas remain where stars are still forming. Already visible are several young bright blue stars whose light and winds are burning away and pushing back the remaining filaments and walls of gas and...

Explanation: In 1995, a now famous picture from the Hubble Space Telescope featured Pillars of Creation, star forming columns of cold gas and dust light-years long inside M16, the Eagle Nebula. This remarkable false-color composite image revisits the nearby stellar nursery with image data from the orbiting Herschel Space Observatory and XMM-Newton telescopes. Herschel's far infrared detectors record the emission from the region's cold dust directly, including the famous pillars and other structures near the center of the scene. Toward the other extreme of the electromagnetic spectrum, XMM-Newton's X-ray vision reveals the massive, hot stars of the nebula's embedded star...

The famous "pillars of creation" – clouds of dust and gas imaged by the Hubble Space Telescope, are no more – a supernova blast wave has blown them apart. But their ghostly image will linger for another thousand years because of the time it takes for light to travel from them to Earth. The pillars have been astronomical icons since Hubble imaged them in 1995 (scroll down for Hubble image). They are part of a larger star-forming region called the Eagle Nebula, which lies 7000 light years away. That means we are seeing the pillars as they were 7000 years...

SEATTLE – They helped open the public's eyes to the wonders of space when they were first photographed in 1995, but a new study suggests the famous Pillars of Creation in the Eagle Nebula might have already been toppled long ago, and that what the Hubble Space Telescope actually captured was their ghost image. A new picture of the Eagle Nebula shot by NASA's Spitzer Space Telescope show the intact pillars next to a giant cloud of glowing dust scorched by the heat of a massive stellar explosion known as a supernova [image]. Astronomers think the supernova's shock wave knocked...

The rifle that today's infantry uses is little changed since the 1960s—and it is badly flawed. Military lives depend on these cheap composites of metal and plastic. So why can't the richest country in the world give its soldiers better ones? One afternoon just a month and a half after the Battle of Gettysburg, Christopher Spencer, the creator of a seven-shot repeating rifle, walked Abraham Lincoln out to a grassy field near where the Washington Monument now stands in order to demonstrate the amazing potential of his new gun. Lincoln had heard about the mystical powers of repeating rifles at...
