Celebrating Genocide – The Real Story of Thanksgiving

Irwin Ozborne, ContributorThanksgiving: Celebrating all that we have, and the genocide it took to get it.Thanksgiving is one of the most paradoxical times of the year. We gather together with friends and family in celebration of all that we are thankful for and express our gratitude, at the same time we are encouraged to eat in excess. But the irony really starts the next day on Black Friday. On Thursday we appreciate all the simple things in life, such as having a meal, a roof over [...]

Astronomers Giddy Over What They Call A Cosmic ‘Dinosaur Egg’ About To Hatch



cosmic dinosaur egg
The Antennae galaxies, shown in visible light in a Hubble image (upper image), were studied with ALMA, revealing extensive clouds of molecular gas (center right image). One cloud (bottom image) is incredibly dense and massive, yet apparently star free, suggesting it is the first example of a prenatal globular cluster ever identified.


Excerpt from huffingtonpost.com

A dense cloud of gas 50 million light-years away has astronomers buzzing, and they're using all sorts of strange metaphors to get the rest of us to pay attention.

They've discovered what they think may be a globular cluster -- a big ball of up to one million stars -- on the verge of being born.

“This remarkable object looks like it was plucked straight out of the very early universe," Dr. Kelsey Johnson, an astronomer at the University of Virginia in Charlottesville and lead author on a paper about the research, said in a written statement. "To discover something that has all the characteristics of a globular cluster, yet has not begun making stars, is like finding a dinosaur egg that’s about to hatch.”

Johnson and her colleagues spotted the bizarre object, which they call the "Firecracker," using the Atacama Large Millimeter/submillimeter Array (ALMA) in the Atacama desert in Chile. It's located inside a pair of interacting galaxies known to scientists as NGC 4038/NGC 4039, or The Antennae Galaxies.

The Firecracker has a mass that's 50 times that of our sun, and is under an enormous amount of pressure -- roughly 10,000 times greater than the average pressure in interstellar space. According to the researchers, this makes it a good candidate for collapsing into a globular cluster within the next million years.

What do other scientists make of the discovery? Dr. Alison Peck, ALMA scientist at the National Radio Astronomy Observatory, who was not involved in the new research, called it "important" and said she was "really excited to hear about these results."
She told The Huffington Post in an email:
"One of the things that we all yearn to understand is how our surroundings formed, how our galaxy and our solar system came to be. To do this, since we can’t actually watch things change over time, (it just takes too long), we need to find similar objects at different stages of development and compare them. What Dr. Johnson’s team have found here is an analog of an object that we look for in the very early universe, but they’ve found it so close by that we’ll be able to make extremely detailed observations and find out much more about the physical conditions in this exciting region."
The research is set to be published in the Astrophysical Journal.

High School students spots relic of ancient sun with super wide orbit



Pulsars are types of neutron stars; the dead relics of massive stars. What sets pulsars apart from regular neutron stars is that they’re highly magnetized, and rotating at enormous speeds.

Excerpt from uncovercalifornia.com

A Pulsar with the widest orbit around a neutron star has been discovered by a team of high school students and the discovery has been confirmed by astronomers. High School students from many states who participated in NSF-funded educational outreach program have found the pulsar after analyzing data from Robert C. Byrd Green Bank Telescope (GBT).

In a research paper accepted by the Astrophysical Journal, lead author Joe Swiggum, a graduate student in physics and astronomy at West Virginia University in Morgantown, said, “Pulsars are some of the most extreme objects in the universe. The students' discovery shows one of these objects in a really unique set of circumstances.”

The object has been codenamed PSR J1930-1852 by astronomers. It was discovered in 2012 by Cecilia McGough from Strasburg High School in Virginia and De'Shang Ray from Paul Laurence Dunbar High School in Baltimore, Maryland.

The discovery of a pulsar with extra wide orbit could help in understanding the concepts behind binary neutron star systems. Nearly 10 percent of known pulsars are in binary systems with most of them orbiting white dwarf companion stars. The Pulsar has been found with the widest separation from the other star in the binary neutron system.

During Pulsar Search Collaboratory (PSC) workshop in summer, students who are interested in analyzing survey data collected by Green Bank Telescope (GBT), spend weeks in checking data plots and searching for unique signatures of pulsars.

The Pulsar Search Collaboratory is a joint venture between the National Radio Astronomy Observatory and West Virginia University which offers real research opportunity to students.

Ghost of child captured on Facebook wedding photo?



(Reddit)

A newly married couple had just finished taking wedding photos when things took a weird turn.
The couple uploaded their favorite photo to Facebook when a friend noticed something sinister about the picture.


Excerpt from theepochtimes.com

There’s a small space between the couple in the picture. Peering out of that space is what appears to be some type of ghost. 

Christiana Dennis actually had the picture as her profile photo when a friend noticed the weird face. 
”Me and my wife’s favourite wedding photo… Until we saw what was between us,” said Kevin Dennis, of Virginia, in a Reddit post.

“We still don’t know who it was.”
(Reddit)

Christiana’s sister said that it might be her but Kevin said the face looks nothing like his wife’s sister, instead appearing to be a baby or some sort.

Speculation on the social media website has suggested it may be a future child for the couple while others say it may be a ghost from the area.

Radio bursts from space reveal strange mathematical pattern





Excerpt from foxnews.com

Eleven fast radio bursts from space seem to follow a strange mathematical pattern, according to a new study – and it has researchers scratching their heads. 

According to study co–authors Michael Hippke of the Institute of Data Analysis in Neukirchen-Vluyn,  Germany, and John Learned of the University of Hawaii in Manoa, the bursts– which were first detected in 2001 – all had dispersion measures that were integer multiples of the same number: 187.5. “The astronomers that found [the bursts] have not seen such things before and do not understand them,” Learned told FoxNews.com.

Nobody knows what causes fast radio bursts, known as FRBs. They only last a few milliseconds, and only one so far has been captured live (by the Parkes Telescope in Australia last year). Though the bursts release just as much energy in a few milliseconds as the sun does in a month, their brevity indicates that the source must be small, with estimates being several hundred miles across at most.

Researchers use dispersion measures, which records how much “space gunk” the burst has passed through, to estimate the distance an FRB has travelled. For instance, a low frequency FRB will have more gunk on it, indicating a longer trip, whereas a high frequency FRB will be cleaner, indicating it came from closer to Earth.
The fact that all of the FRBs’ dispersion measures are integer multiples of 187.5 has, according to Hippke and Learned’s team’s calculations, a 5 in 10,000 chance of being coincidental. The dispersion measures also indicate that their origin is relatively close to Earth, but unlikely from within our own galaxy.

There are numerous theories on where these bursts came from, including speculation that the messages are from extraterrestrial intelligence. To the scientific community, however, this theory doesn’t really hold water, and is seen as more of a last resort only after all other avenues have been exhausted.

“We think these are likely from some very energetic process, like a burst from a high magnetic field neutron star or energy released [when] two neutron stars merge,” Professor Maura McLaughlin of the West Virginia University Center for Astrophysics explained. “The thing that made people think they were possibly from ETs was a recent paper that showed that one fundamental property is quantized in a way that wouldn't be expected if the signals were naturally occurring. However, I imagine that correlation will totally go away once more are discovered.”

Learned himself is dubious of an alien source as well, noting that he and Hippke only noted the dispersion measures’ “peculiar” pattern, and that they may even be coming from Earth. “We are now leaning more towards a terrestrial, anthropogenic interpretation,” he said. “At this point I would place my money on some sort of governmental satellite, not a natural phenomena, but I would not bet much.  More data, which reportedly [is] being analyzed but which we have no insider information about yet, will be most interesting and refute or confirm our hypotheses.” He also noted that he’d only look to an ETI interpretation once all other possibilities have been eliminated.

As for McLaughlin, she believes there’s no way the FRBs could be messages from aliens, as the signals are very broadband and emitted over a wide range of radio frequencies. “It would take a LOT of energy for an alien civilization to produce these bursts - they'd need to harness the energy of many, many suns - and there's no real advantage for communication to send a signal over such a large bandwidth.”

An Alien Radio Beacon? Possibly Not This Time



An Alien Radio Beacon? Possibly Not This Time.

For practically a decade, astronomers have puzzled over strong bursts of radio energy that appear to be hailing from billions of light years away. Recently, we received reports of a new wrinkle to this mystery: The bursts seem to comply with a mathematical pattern, one that does not line up with something we know about cosmic physics.

And, of course, when we hear “mathematical pattern,” “radio transmission,” and “outer space,” all strung collectively, we straight away jump to our preferred explanation—aliens! (Or, you know, a decaying pulsar star, an unmapped spy satellite, or a cell telephone tower.)

It’s also probable that the pattern doesn’t basically exist.

Because 2007, telescopes have picked up almost a dozen so-known as “fast radio bursts,” pulses that last for mere milliseconds, but erupt with as a great deal power as the sun releases in a month. Where could they be coming from? To come across out, a group of researchers took advantage of a basic principle: That higher frequency radio waves encounter less interference as they traverse space, and are detected by our telescopes earlier than reduce frequency waves. The time delay, or “dispersion measure”, in between larger and reduce frequency radio waves from the very same pulse event can be applied to figure out the distance those waves traveled.

Here’s where things got weird. When researchers calculated the dispersion distance for each and every of eleven rapid radio bursts, they identified that every distance is an integer many of a single number: 187.5. When plotted on a graph, as the researchers show us in Figure 1 of their paper, the points type a striking pattern.

A single explanation is that the bursts are coming from distinctive sources, all at on a regular basis spaced intervals from the Earth, billions of light years away. They could also be brought on by a smaller cosmic object a lot closer to residence, such as a pulsar star, behaving according to some sort of physics we don’t yet understand. And then there’s the possibility that aliens are trying to communicate, by blasting simple numeric patterns into space.

But no matter how you slice it, eleven data points is a tiny sample set to draw any meaningful conclusions from. A handful of deviant observations could bring about the complete pattern to unravel.

And that is precisely what seems to be happening. As Nadia Drake reports for National Geographic, newer observations, not integrated in the most up-to-date scientific report or other well known media articles, don’t fit:

“There are 5 quickly radio bursts to be reported,” says Michael Kramer of Germany’s Max Planck Institute for Radioastronomy. “They do not fit the pattern.”
Rather of aliens, unexpected astrophysics, or even Earthly interference, the mysterious mathematical pattern is probably an artifact produced by a little sample size, Ransom says. When working with a limited quantity of data – say, a population of 11 quickly radio bursts – it’s straightforward to draw lines that connect the dots. Usually, on the other hand, these lines disappear when much more dots are added.
“My prediction is that this pattern will be washed out quite immediately after a lot more fast radio bursts are located,” says West Virginia University’s Duncan Lorimer, who reported the very first burst in 2007. “It’s a great instance of how apparently considerable final results can be identified in sparse information sets.”

That is a bit of a bummer, but nevertheless, these radio bursts are fascinating, and what could be causing them remains as a lot of a mystery as ever. It could even nonetheless be aliens, if not an alien beacon. As SETI Institute Director Seth Shostak told me in an e mail:

“If it is a signal, nicely, it is surely NOT a message — except perhaps to say ‘here we are’. There’s not actual bandwidth to it, which suggests these speedy radio bursts can not encode several bits. But there are so many other possibilities, I feel that automatically attributing one thing in the sky that we don’t (at very first) understand to the operate of aliens is … premature!”

If there’s 1 point that is clear in this whole organization, it is that we’ve nonetheless got plenty to discover about the patterns woven into the universe around us.

Surface of Venus revealed by new radio telescope data


http://www.smnweekly.com/wp-content/uploads/2015/03/Surface-of-Venus-revealed-by-new-radio-telescope-data.jpg



Excerpt from smnweekly.com
By David M. DeMar

New radio telescope data from the National Radio Astronomy Observatory has revealed for the first time ever just what Venus has under its thick veil of clouds that otherwise occlude its surface from view.
25 million miles distant from us, Venus looks to the naked eye – or through a light telescope – much like a cloudy marble, thanks to the thick cloudbanks of carbon dioxide ringing the planet. However, the surface underneath, long a mystery to planetary scientists, has been laid bare thanks to the work of Puerto Rico’s Arecibo Observatory radio transmitter and the Green Bank Telescope, a radio telescope located in West Virginia and operated by the National Science Foundation.
The two facilities worked together with the NRAO in order to uncover the hidden surface of Mars. Arecibo sent radar signals to Venus, where they penetrated the thick atmosphere and bounced off the ground. The returning radio signals were picked up by the GBT in West Virginia in a process known as bistatic radar; the result is a radar image that shows craters and mountains strewn across the surface of Venus at a surprisingly high resolution.
The image is bisected by a dark line, representing areas where it’s particularly difficult to receive useful image data through the use of bistatic radar. However, scientists are intending to compare multiple images as time goes by in order to identify any active geologic processes on the surface of Venus such as volcanic activity.
It’s no particularly easy task to compare radar images in search of evidence of any change in this manner says Smithsonian senior scientist Bruce Campbell, but the work will continue. Campbell, who works at the National Air and Space Museum in the nation’s capital and is associated with the center for Earth and Planetary Studies, added that combining images from the latest NRAO endeavor and others will yield large amounts of data on how the surface of Venus might be altered by other processes.
The radar data, and a scientific paper based on it, will be published in April in Icarus, the scientific journal dedicated to studies of the solar system.

Mars Capsule Test Heralds New Space Age With Musk Alongside NASA




Excerpt from
bloomberg.com

The U.S. is preparing to launch the first craft developed to fly humans to Mars, presaging a second space age -- this one fueled by billionaires like Elon Musk rather than a Cold War contest with the Soviet Union. 

An unmanned version of the Orion spaceship built by Lockheed Martin Corp. (LMT) is scheduled for liftoff tomorrow to an altitude of 3,600 miles (5,800 kilometers), the farthest from Earth by a vehicle designed for people since the Apollo program was scrapped in 1972. 

Entrepreneurs such as Musk and longtime contractors like Lockheed are helping shape the technology needed to find other homes for humanity in the solar system with an eye to one day commercializing their work. 

“These are really exciting times for space exploration and for our nation as we begin to return to the ability to fly humans to space,” said Jim Crocker, vice president and general manager of civil space at Lockheed Martin Space Systems. “What Orion is about is going further into space than humans have ever gone before.”

Launched from Kennedy Space Center in Florida atop a Delta IV rocket, the Orion capsule will test the riskiest systems needed to carry astronauts far beyond the moon, although its first flight will cover only about 2 percent of the 238,900-mile distance to the lunar surface.

Speed Limit

After orbiting earth twice, Orion will accelerate to 20,000 miles per hour during descent, mimicking the speeds of a craft returning from a mission to deep space. The capsule is supposed to make a parachute-cushioned splashdown in the Pacific Ocean off Mexico’s Baja peninsula. 

To explore the universe, the National Aeronautics and Space Administration must first redevelop capabilities abandoned more than 40 years ago when the U.S. shifted focus from Apollo’s lunar forays to rocketing crews a few hundred miles to low Earth orbit.
NASA has used Russian craft to reach the International Space Station since the space shuttle program ended in 2011. 

In a strategic shift, the Obama administration canceled plans to return to the moon, turning some flights to commercial companies while setting its sights -- and limited funds -- on pioneering deep space. The Orion capsule was originally commissioned in 2006 for the defunct Constellation program.

Musk, Bezos

Those moves paved the way for technology chieftains including Musk and Amazon.com Inc. (AMZN) founder Jeff Bezos to pursue their own space ambitions. 

Musk founded Hawthorne, California-based SpaceX in 2002 with the goal of enabling people to live on other planets, a massive endeavor that would require innovations such as reusable rocket stages to lower costs. 

Mars is also in focus for NASA as the space agency maps plans to “pioneer the space frontier,” according to a May 29 white paper.

$22 Billion

NASA proposes an initial $22 billion effort that includes two other Orion missions over the next eight years and building a powerful new rocket. The Delta IV being used tomorrow is manufactured by United Launch Alliance, a Lockheed-Boeing Co. (BA) venture.

A new Space Launch System rocket being developed by the partnership is slated to hoist the next Orion craft beyond the moon in fiscal 2018, Lockheed’s Crocker said in a phone interview. The first manned Orion mission is slated for early in the next decade.
NASA’s plans are “sketchy” beyond that, aside from broad goals to capture asteroid samples in the 2020s and reach Mars a decade later, said Marco Caceres, director of space studies with Fairfax, Virginia-based consultant Teal Group. 

Average Distance

While Mars’s distance from Earth varies because of the two planets’ orbits, the average is about 140 million miles, almost 600 times longer than a trip to the moon. It’s so far that radio communications take as long as 20 minutes to travel each way, according to Bill Hill, NASA’s deputy associate administrator for exploration systems development. 


Entrepreneurs such as Musk will have opportunities to get involved as NASA refines capsule and rocket designs. NASA plans to develop two larger rockets beyond the initial launch vehicle, which will be capable of hauling a 70-metric ton payload. 

“We’re not taking any options off the table,” Hill said. “We want to be sufficiently flexible so that if we find a new path, we can introduce it and not change course.” 

Expense, shifting political priorities and the lack of a clear NASA road map could still derail the latest effort as they did the Apollo program in the early 1970s, said Micah Walter-Range, director of research analysis with the Space Foundation, a non-profit organization based in Colorado Springs, Colorado. 

“All of the challenges that exist are surmountable,” Walter-Range said by phone. “It’s just a question of having the money to do it.”

Homeless Stars? Well, Galaxy-less Stars Anyway ~ Greg Giles


Lonesome Stars
Time-lapse photograph of the CIBER rocket launch, taken from NASA’s Wallops Flight Facility in Virginia

In Friday’s issue of the journal Science, conclusions from the Cosmic Infrared Background Experiment or CIBER, suggest that as many as half of all stars in our universe may lie outside the home of galaxies. Not visible through Earth-bound telescopes due to their faint glow, these lone stars may be the points that connect galaxies together in a far spanning web of light.   

These 'homeless' stars are believed by astronomers to have been evicted by their galaxies by mergers and collisions.

NASA program scientist Michael Garcia said this dim glow between galaxies is as bright as all the known galaxies combined, and is redefining previous understandings of galactic structure. Instead of being defined by sharpened borders, galaxies may span further outward, thinning like a morning mist over a darkened pond.
