New Photo Shows Powerful Jets on Mars-Bound Comet C/2013 A1

NASA recently released images of comet C/2013 A1 that will pass within 84,000 miles of Mars — less than half the distance between Earth and our moon – on October 19, 2014.

The image on the left, captured March 11 by NASA’s Hubble Space Telescope, shows the comet at a distance of 353 million miles from Earth.

Hubble can’t see C/2013 A1’s icy nucleus because of its small size, and the nucleus is surrounded by a glowing dust cloud that measures roughly 12,000 miles across. The left image is the comet as it appears to Hubble, and the right image has been processed to show see through the comet’s coma, revealing two jets of dust being blasted off the surface.

The comet was observed as Earth was crossing through it’s path around the Sun. This positioning of the two bodies allowed astronomers to determine the speed of the dust coming off the nucleus.

“This is critical information that we need to determine whether, and to what degree, dust grains in the coma of the comet will impact Mars and spacecraft in the vicinity of Mars,” said Jian-Yang Li of the Planetary Science Institute in Tucson, Arizona.

Discovered in January 2013 by Robert H. McNaught at Siding Spring Observatory, the comet is falling toward the sun along a roughly 1 million year orbit and is now within the radius of Jupiter’s orbit. The comet will make its closest approach to our sun on Oct. 25, at a distance of 130 million miles – well outside of Earth’s orbit. The comet is not expected to become bright enough to be seen by the naked eye.

5 Times the United States Almost Nuked Itself

Oops. Presenting 5 times the United States almost nuked itself.

The threat of a nuclear explosion in the United States was at its height between World War 2 and the Cold War with Russia. But what if the closest America actually ever came to nuclear destruction was at its own hand?

This compilation of five accidents is the result of military airplane crashes, dangerous science experiments, pilot error and a simple dropped wrench. The crash of a B-52 bomber over Goldsboro, North Carolina saw the release of an atomic bomb over American soil, as did the Mars Bluff incident involving a nuclear-armed B-47 bomber. Both lost nuclear weapons were recovered from those broken arrow incidents, but the same can’t be said for the 1958 accident involving a collision between a B-47 and F-86 fighter jet. That nuclear bomb was lost forever off the coast of Georgia.

Other incidents include the plutonium Demon Core experiments that resulted in chain reactions which killed several nuclear scientists at the Los Alamos National Lab, and the Van Buren ICBM accident in which a nuclear warhead was ejected from a massive missile explosion.

Chicken From Hell Dinosaur Discovered

Meet the chicken from hell dinosaur.

This is the nickname given to a newly discovered dinosaur that lived 66 million years ago. Officially known as “Anzu wyliei,” the 11-foot-long, 500-pound is an oviraptorosaur—a family of two-legged, birdlike dinosaurs. It is among the largest feathered dinosaurs ever found in North America.

Meet the chicken from hell dinosaur.

It was “as close as you can get to a bird without being a bird,” said study leader Matt Lamanna, a vertebrate paleontologist at the Carnegie Museum of Natural History in Pittsburgh. “You might think this was a really, really weird-looking bird,” Lamanna added. “… But, in fact, this was a very bird-like dinosaur … with a really long bony tail, very large hands and really sharp claws.

The Anzu wyliei was probably an omnivore that ate whatever it wanted, including vegetation and small animals. It could easily run down prey, with its thigh bone sporting bony ridges where large muscles could attach.

Fossils of the Anzu wyliei were first excavted from the Hell Creek formation of South and North Dakota several years ago. However, it took years to identify and study all the remains.

Woolly Mammoth Clone Closer to Reality

A woolly mammoth clone may now be a bit closer to reality. This is thanks to an international team of researchers which has discovered blood in a woolly mammoth frozen for 43,000 years.

The woolly mammoth, found May 2013 on Malolyakhovskiy island, has undergone careful study for the past year. The carcass was remarkably well preserved, giving scientists new insight into the mammoth’s digestive and circulatory systems.

Discussing the potential for cloning, Semyon Grigoryev, head of the Mammoth Museum in Yakutsk, part of the Institute of Applied Ecology of the North at the North Eastern Federal University said, “The next question is how to use an elephant in the cloning process. The evolutionary path of the mammoth and the elephant diverged a long time ago. So even if we could get a ‘living cell’ we need to have a special method of cloning. The Koreans are working on getting the clones from different species, but, you see, it is not so fast. If we do not get ‘living cell’, we will have a longer route. Then we should create artificial DNA, it could take 50 or 60 years.”

“So we have a unique opportunity to understand how the mammoth’s blood system worked, its muscles and the trunk. Of course, we are engaged primarily in fundamental science. It is important to us to learn all possible details about mammoth. Maybe our findings will be used by applied science, but now it is early to think of it. And I repeat once again that cloning – despite our discovery, it is a very distant prospect, involving years and decades of work.”

HR 5171 A: The Largest Yellow Star Ever Discovered

The European Southern Observatory’s Very Large Telescope (VLT) has discovered the largest known yellow hypergiant star – HR 5171 A. It is one of the 10 largest stars now know, measuring 1200 times the diameter of the Sun and one million times brighter.

As another point of comparison, it is 50% larger than the famous red supergiant Betelgeuse.

Located 12,000 light years form Earth, the star HR 5171 A is part of an unusual double star system. Its binary partner is so close to it that the two stars actually touch. Together, the system resembles the shape of a peanut.

Yellow hypergiant stars like HR 5171 A are very rare, with only about 12 known to exist in our Milky way galaxy. Their instability means that they expel materials outwards, forming a glowing atmosphere around the core star.

Presenting the most mysterious underground places on Earth, including Chauvet Cave and its strange cave art; Belize’s Actun Tunichil Muknal cave and its Mayan sacrifices; the medieval Erdstall of Europe; Turkey’s massive underground city Derinkuyu; and the strange megalithic underground temple of Malta, the Hypogeum of Hal-Saflieni.

There’s a massive whale graveyard in the middle of the Chilean desert. But what caused it? Paleontologists think they have the answer…

In 2010, a mysterious whale graveyard was found in the middle of Chile’s Atacama Desert, one of the driest places on Earth. The area was covered by the sea millions of years ago, so the discovery of marine mammal fossils wasn’t a surprise. But no one knew why the fossils of so many whales – at least 40 – would be found in the same location…

A paleontologist working with the Smithsonian Institute recently discovered the answer: a common ocean algae. The algae bloomed profusely in the area 6 to 9 million years ago, triggered by iron-rich runoff from the Andes Mountains. The algae produced a deadly neurotoxin that caused rapid organ failure and death when ingested.

One major clue was the fact that all of the whale skeletons were facing belly-up – an indication that they died at sea as opposed to beaching themselves en masse as sometimes seen in marine mammals today. Other clues include fossil algae mats found on the skeletons and the presence of an assortment of other marine mammal fossils in the area. These additional fossils indicate that a large event killed them all at the same time.

The Real Bigfoot Conspiracy

Meanwhile, a Texas man named Rick Dyer has released pictures of a Bigfoot specimen that he claims to have killed outside of San Antonio in 2012. He had been revealing bit of information about the specimen for the past two years in preparation for a world tour with the body…

Dyer says he originally tracked down and shot, not one, but two of the mythical creatures, and the other Bigfoot that he allegedly shot “was taken by the federal government and never returned.”

There are certainly reasons to doubt Dyer’s claims as he has previously been involved with a Bigfoot hoax in 2008 and was arrested for fraud in 2011. But this time, Dyer says you should believe him.

5 Most Secret Military Aircraft

…the airplanes they don’t want you to see.

UFO? Try top secret military aircraft. These are the most mysterious military airplanes, jets and space planes flying today, including the infamous Aurora black triangle, the Boeing X-37, the new Northrop Grumman unmanned RQ-180 stealth drone, the Blackstar space bomber, and the stealth Black Hawk helicopters that hunted down Osama bin Laden.

These incredible black projects were developed under the watch of the US Air Force, the US Navy, the CIA, the US Army and NASA. With numerous sightings, they’ve been the subject of conspiracy theories and investigations for decades.

Tested in top secret locations like Area 51, evidence and footage is difficult to obtain but rumors of their existence continue to persist. They’re often only uncovered after a crash, though any air crash investigations are immediately covered up.

So buckle up for a look at the 5 most secret military aircraft, and don’t be surprised if you encounter a bit of turbulence…
