World’s Biggest Photo: 272 Gigapixel Image Made With Canon 7D Camera

Posted by Ram Kumar Shrestha on April 30, 2012

 

272 Gigapixel Image Biggest In World
You’re looking at the world’s largest photo.

The whopping shot of Shanghai is 272 gigapixels, and was made with a £1000 Canon 7D Camera.

It’s size outshines a 70 gigapixel (70 billion pixels) whopper of Budapest, an 80 gigapixel image of London , a remarkable 26 gigapixel image of Dresden and an 8 gigapixel image of the Milky Way.

To compare the shot you your average household digital camera snaps shots, they usually come up between two and 20 megapixels.

The amazingly detailed image won a competition to create the world’s largest digital photo.

It’s not just one shot though, the massive image is 12,000 photos stitched together.

So how big is a 272 gigapixel image exactly? 1 gigapixel is 1000 megapixels, which is 1 billion pixels. So we’re looking at 272 billion pixels, which is large enough to cover 7000 billboards. Read the rest of this entry »

Mars: ‘Life On The Red Planet Is 99% Certain’ As 1976 Samples Taken By Nasa’s Twin Viking Landers Are Revisted

Posted by Ram Kumar Shrestha on April 13, 2012

 

New analysis of soil samples taken on a Mars mission in 1976 have revealed evidence of life, a report claims.

The samples, collected by Nasa’s twin Viking Mars landers, were initially thought to show proof of geological activity, but not biological evidence.

But new analysis by researchers at the University of Siena and California’s Keck Institute believe the original experiments may have been flawed and that there was proof of microbial life.

“On the basis of what we’ve done so far, I’d say I’m 99 per cent sure there’s life there,” said Joseph D Miller, associated professor of cell and neurobiology at the University of Southern California’s Keck School. Read the rest of this entry »

The Whole Universe In One Photo

Posted by Ram Kumar Shrestha on April 4, 2012


Comment: Thanks NASA for giving opportunity to have a look to the whole universe sitting on chair:

Nasa has unveiled an astounding new image of our galactic neighbourhood – a new star atlas for the entire universe.

The atlas includes a catalogue of the entire infrared sky, over half a billion stars, galaxies and more captured by the Wide-field Infrared Survey Explorer (WISE) mission.

Edward Wright, WISE principal investigator at UCLA, said: “Today, WISE delivers the fruit of 14 years of effort to the astronomical community.” Wright began working on the WISE mission in 1998.

Made up of more than 2.7 million images taken at four infrared wavelengths of light, the new image captures everything from nearby asteroids to distant galaxies. Read the rest of this entry »

Nasa Video Shows Moon Was Once A Huge Fireball – PHOTOS, VIDEO

Posted by Ram Kumar Shrestha on March 19, 2012

  

An amazing new animation from Nasa shows how the grey, puckered rock that is our moon, was once a flaming inferno under asteroid attack.

The video shows that the moon was not always the cool, scarred rock we’re used to seeing today; 4.5 billion years ago, it was a flaming hot mass of lava.

Then, 0.2 billion years later, the Aitken basin at the moon’s south pole was formed by asteroid strike before the the moon came under mass assault by further asteroids between 4.1 and 3.8 billion years ago, forming several basins across the celestial body. Read the rest of this entry »

Yahoo Sues Facebook

Posted by Ram Kumar Shrestha on March 13, 2012


Business war:

Yahoo is suing Facebook over patents, weeks before the social-networking heavyweight is due to cash in with its initial public offering of stock.

Yahoo said in a US court filing that Facebook had infringed 10 of its patents covering advertising, privacy controls and social networking.

Yahoo had threatened to sue Facebook last month, insisting that the social network license its patents. Facebook vowed to defend itself vigorously against what it called “puzzling actions” by Yahoo.

“We’re disappointed that Yahoo, a long-time business partner of Facebook and a company that has substantially benefited from its association with Facebook, has decided to resort to litigation,” Facebook said. Read the rest of this entry »

Facebook Pages Now Get Timeline

Posted by Ram Kumar Shrestha on February 29, 2012

Facebook Timeline for pages has just been released, bringing the new Timeline look to the brand and organisation pages you “like” on Facebook.

All pages will switch to the new design by March 30, whether or not brands optimise their profiles, and add a big header image.

Any Facebook change naturally brings out some love and hate. Some brands will love it, especially those who update their pages often. For others, it will show up how infrequently they update their page.

Facebook users took to Twitter to vent their spleen over the change, with feelings evenly split between love and hate.

Ian Schafer from Deep Focus told Mashable: “It’s an opportunity for brands to tell more engaging stories on Facebook than they can now,” Schafer said. “It puts them more in control of their content.” Read the rest of this entry »

CERN’s Loose Cable To Blame For Proving Einstein Wrong

Posted by Ram Kumar Shrestha on February 26, 2012

Note to Einstein naysayers – check your equipment before trying to prove the chief geek wrong.

A loose wire may be to blame for CERN’s claim late last year that Einstein’s theory of special relativity, proposed in 1905, was actually incorrect.

The theory states that nothing in the universe can travel faster than the speed of light in a vacuum.

It took just 2.3 milliseconds for light to travel between the Geneva and Gran Sasso laboratories.

CERN showed that the accepted speed of light could be broken by 60 nanoseconds, or more precisely that neutrinos arrived 60 nanoseconds too early than if they were travelling at the speed of light, breaking the speed of light itself by 0.00248%. Two experiments reached the same conclusion.

The Telegraph reports that a loose wire at CERN might mean Einstein is not wrong. Read the rest of this entry »

‘Marsquake’, How Earthquakes On Mars Could Sustain Alien Life (PICTURES)

Posted by Ram Kumar Shrestha on February 25, 2012

 

Recent earthquakes on Mars point at the existence of active volcanoes and liquid reservoirs that could sustain life on the Red Planet.

A recent quake with a magnitude of 7 is thought to have occurred after scientists analysed tracks made by boulders that toppled from a Martian cliff.

The paths of the rocks, which ranged from 6.5 to 65 feet in diameter, were captured by Nasa’s Mars Reconnaissance Orbiter, and were analysed by a University of London team. Read the rest of this entry »

Facebook To Turn On Timeline For All Users This Week

Posted by Ram Kumar Shrestha on January 29, 2012

Changes to Facebook always provoke controversy and more is expected during the next few weeks as users are forced to adapt to the website’s Timeline feature.

The social media website is rolling out the feature which it says will allow people to give a better idea of who they are.

Although users were able to opt into the new Timeline from December 15, the feature is to become a staple part of the website, but users will have seven days to add or remove things from their Timeline before it is visible to friends.

This latest change to Facebook will allow people to access easily their friends’ status updates and photographs from as far back as 2004 when Facebook was founded – but the website insists that the change does not affect users’ privacy.

A spokeswoman for Facebook said: “Timeline does not change any of your existing privacy settings.”

The seven-day period before the new timeline goes live allows users to remove any aspects of their profile from a few years ago that they may regret posting on their page. Read the rest of this entry »

FBI plans social network map alert mash-up application

Posted by Ram Kumar Shrestha on January 27, 2012

FBI Develops Facebook Spy Tool

The FBI is seeking to develop an early-warning system based on material “scraped” from social networks.

It says the application should provideinformation about possible domestic and global threats superimposed onto maps “using mash-up technology”.

The bureau has asked contractors to suggest possible solutions including the estimated cost.

Privacy campaigners say they are concerned that the move could have implications for free speech.

The FBI’s Strategic Information and Operations Center (SOIC) posted its “Social Media Application” market research request onto the web on 19 January, and it was subsequently flagged up by New Scientist magazine.

The document says: “Social media has become a primary source of intelligence because it has become the premier first response to key events and the primal alert to possible developing situations.”

It says the application should collect “open source” information and have the ability to:

  • Provide an automated search and scrape capability of social networks including Facebook and Twitter.
  • Allow users to create new keyword searches.
  • Display different levels of threats as alerts on maps, possibly using colour coding to distinguish priority. Google Maps 3D and Yahoo Maps are listed among the “preferred” mapping options.
  • Plot a wide range of domestic and global terror data.
  • Immediately translate foreign language tweets into English. Read the rest of this entry »

Stephen Hawking: We Should Colonise Mars But Encountering Aliens ‘Will Not End Well’

Posted by Ram Kumar Shrestha on January 8, 2012

Professor Stephen Hawking told listeners of BBC Today programme that he thought humans would almost definitely colonise Mars, but he warned against encouraging alien encounters.

As Stephen Hawking’s 70th birthday approaches, the scientist who was told he wouldn’t live past 40 answered some of the public’s questions focusing on humanity’s destiny to inhabit outer space.

A bit of a futurist, Hawking’s latest book, George’s Secret Key To The Universe is an explanation of the world aimed at children, a lesson for the next generation.

It’s not the first time Hawking has advised people to“reach out to the stars.” The physicist has long been outspoken on the subject of humanity’s intergalactic future.

He was the first quadriplegic to experience zero gravity, after a sub orbital space flight in 2009. At the time, he justified the £100,000 needed (and donated by Richard Branson) by saying:

“Many people have asked me why I am taking this flight. I am doing it for many reasons.

“First of all, I believe that life on Earth is at an ever-increasing risk of being wiped out by a disaster such as sudden nuclear war, a genetically engineered virus, or other dangers.

“I think the human race has no future if it doesn’t go into space. I therefore want to encourage public interest in space.”

This anxiety was picked up again in Hawking’s answer on the Today programme. He was asked “Do you think the human race will survive all potential disasters and eventually colonise the stars?”

His response reflects worries of biological and particularly nuclear warfare:

“It is possible that the human race could become extinct, but it is not inevitable.

“I think it is almost certain that a disaster such as nuclear war or global warming will befall the Earth within a thousand years.”

American X-37B Space Plane ‘Probably’ Spying On China

Posted by Ram Kumar Shrestha on January 5, 2012

A classified American spy plane is “probably” spying on China, a report in Spaceflight magazine has claimed.

Neither the Pentagon or the US Air Force have revealed what mission their X-37B vehicle, which is unmanned and has been in space since March, is undertaking.

However amateur space researchers have been tracking the plane, and say they have compiled enough evidence to reveal what it’s up to from a low orbit about 300km above the Earth.

According to Spaceflight and the BBC, the X-37B’s path is almost exactly the same as China’s Tiangong-1 space laboratory.

“We think the X-37B may be using to maintain a close watch on China’s nascent space station,” Spaceflight editor Dr David Baker told the BBC.

Other researchers quoted in the Spaceflight article, which will be published on Saturday, claim that if the Pentagon wanted to spy on Tiangong-1 it could do so without using the X-37B, and argue the similarity in their flight path could just be a coincidence.

The US Navy has kept tight-lipped about the X-37B, saying merely that it is a testbed for new technologies.

The Boeing-built craft, which is about 9m long, reusable and can automatically land on a runway. It also has space for a payload about the size of a small van – but what is carried inside is not known.

China expects to send its astronauts to the lab later this year. Whether or not they’ll be greeted by the mysterious American spaceship or not is yet to be seen.

Of course given the state of the Pentagon’s research into creating time holes to hide entire events inside, it’s possible they’ll never know either way.

Are Aliens On The Moon? Scientists Want YOU To Join The Search

Posted by Ram Kumar Shrestha on December 26, 2011

American scientists want to enlist online volunteers to identify signs of alien life in moon images collected by NASA’s Lunar Reconnaissance Orbiter (LRO).

Physicists Paul Davies and Robert Wagner ofArizona State University believe there may be signs of extra terrestrial life in the form of messages, scientific instruments, waste or evidence of mining that could be spotted by human telescopes and orbiting spacecraft.

In their paper published online in the journal Acta Astronautica, the pair wrote: “Although there is only a tiny probability that alien technology would have left traces on the moon in the form of an artefact or surface modification of lunar features, this location has the virtue of being close, and of preserving traces for an immense duration.

“If it costs little to scan data for signs of intelligent manipulation, little is lost in doing so, even though the probability of detecting alien technology at work may be exceedingly low.”

The paper adds: “Alien civilizations may have sent probes to our region of the galaxy. Any mission to the solar system would probably have occurred a very long time ago.

“The lunar environment could preserve artefacts for millions of years.”

Chib(3P) Discovered: Large Hadron Collider Scientists Find New Subatomic Particle

Posted by Ram Kumar Shrestha on December 22, 2011

Large Hadron Collider scientists including a group from the UK believe they have detected their first new subatomic particle.

Known as Chi (the Greek X symbol) b (3P), it is a “boson” like the fabled Higgs particle believed to underpin mass.

Chib(3P) provides a new way of combining two other elementary particles, the “beauty” quark and its antiquark, so that they bind together.
Quarks are the building blocks of protons and neutrons, which form the cores of atoms.

They come in six different “flavours” including “beauty”, also known as the “bottom” quark.
Unlike the hypothetical Higgs which is not made up of smaller particles, Chib(3P) combines two heavy objects via the same “strong” force that holds the atomic nucleus together.

What is thought to be a clear signal of the particle was found in data from Atlas, one of the Large Hadron Collider’s four huge detectors.

The £4 billion particle accelerator, dubbed the “Big Bang Machine”, fills a 27-kilometre circular tunnel that straddles the Swiss-French border near Geneva.

It is designed to recreate the conditions moments after the Big Bang that created the universe 13.7 billion years ago.
The new findings are published today in the online scientific archive arXiv.

Dr Miriam Watson, a member of the Collider team from the University of Birmingham, said: “The lighter partners of the Chib(3P) were observed around 25 years ago. Our new measurements are a great way to test theoretical calculations of the forces that act on fundamental particles, and will move us a step closer to understanding how the universe is held together.”

God Particle: Why The Truth About The Higgs Boson Is Still Probably Stranger Than Fiction

Posted by Ram Kumar Shrestha on December 13, 2011

Physicists at Cern, the European Organisation for Nuclear Research, have announced new evidence hinting towards – although not quite confirming – the existence of the so-called God Particle, aka the Higgs Boson.

Current best guesses put the date of the Higgs’ final discovery at some time towards the end of 2012.

The elusive particle is almost impossible to see with human instruments, but theoretically makes up much of the mass of the universe and helps explain missing elements in the General Model of How Stuff Works.

If that sounds simplistic, well, it is. When it comes to the Higgs Boson, it’s hard to be anything but.

The Large Hadron Collider (LHC) itself is difficult enough to describe. It stretches for 27km around the French-Swiss border at a depth of 100m, and accelerates particles to near the speed of light in order to smash them together and inspect the debris. Costing more than £6bn it’s one of the largest, most expensive and most complicated experiments in the world.

But what does that really mean? Without the bits in between – the science – the LHC just sounds like a big, weird tunnel.

The problem is that reporting about anything to do with Cern is hideously difficult for non-scientists, and doing so on deadline in under 500 words is even harder. Read the rest of this entry »
