Pluto shows its spots to Nasa probe







The science team on the American New Horizons mission to Pluto has released two colour views of the dwarf planet and its biggest moon, Charon.


They were made by combining pictures from the probe’s high-resolution, “black and white” camera, Lorri, and its lower-resolution, colour imager known as Ralph.


The difference in hue between Pluto and Charon is clear.
But what catches the eye are four dark spots on the 2,300km-wide dwarf planet.
Each spot is about 500km across. Quite why they should be so similar in size and spacing is not clear.
Their dominant placing is on the hemisphere that New Horizons will not see during its close flyby on 14 July.

However, there should be ample opportunity to study them in the days leading up to the encounter.
“It’s a real puzzle - we don’t know what the spots are, and we can’t wait to find out,” said New Horizons principal investigator, Alan Stern, of the Southwest Research Institute.
“Also puzzling is the longstanding and dramatic difference in the colours and appearance of Pluto compared to its darker and greyer moon Charon.”

If, as scientists think, Pluto and Charon are the products of a collision between two primitive bodies in the early Solar System, one might expect them to look more similar.
New Horizon’s flyby data will hopefully provide the answer.
The US space agency (Nasa) mission is now closing in on Pluto and its five moons.
The moment of closest approach on the 14th will take place at 11:49 GMT, when the probe is just 12,500km above the surface.



It is moving too fast - at 13.7km/s - to go into orbit, and it will simply scream past the dwarf and its satellites, gathering as much data as it can.
No pictures will be sent back to Earth on the day itself; the spacecraft will be too busy executing its pre-programmed observation campaign.
Instead, the first images from the flyby should be presented on the following day, on 15 July.
Controllers have decided not to alter the course of the probe.
They had been looking for icy debris in the vicinity of Pluto that might pose a collision hazard, but could find nothing obvious.
New Horizons was commanded to make a thruster burn earlier this week, to speed it up ever so slightly.
This will ensure the spacecraft reaches a precise point in space and time to carry out the pre-programmed observation sequence.
The probe must spin around to take pictures of all the different targets, and if its navigation is off by even a small amount it will be looking in the wrong direction at the critical moment.
On Thursday, New Horizons was just under 15 million km from Pluto, but 4.7 billion km from Earth.
The vast distance to the probe's home world means a radio signal takes about 4.5 hours from sending to receipt.

Largest single personal data hack ever? 360mn stolen account credentials found online

A cyber security firm has reported a “mind boggling” cache of stolen credentials which has been put up for sale on online black markets. A total of 360 million accounts were affected in a series of hacks, one of which seems to be the biggest in history.

Alex Holden, chief information security officer of Hold Security LLC, said that the firm had uncovered the data over the past three weeks.

He said that 360 million personal account records were obtained in separate attacks, but one single attack seems to have obtained some 105 million records which could make it the biggest single data breach to date, Reuters reports. “The sheer volume is overwhelming,” said Holden in a statement on Tuesday.

“These mind boggling figures are not meant to scare you and they are a product of multiple breaches which we are independently investigating. This is a call to action,” he added.

Hold Security said that as well as 360 million credentials, hackers were also selling 1.25 billion email addresses, which may be of interest to spammers.

The huge treasure trove of personal details includes user names, which are most often email addresses, and passwords, which in most cases are unencrypted.

Hold Security uncovered a similar breach in October last year, but the tens of millions of records had encrypted passwords, which made them much more difficult for hackers to use.

“In October 2013, Hold Security identified the biggest ever public disclosure of 153 million stolen credentials from Adobe Systems Inc. One month later we identified another large breach of 42 million credentials from Cupid Media,”
 Hold Security said in statement.

Holden said he believes that in many cases the latest theft has yet to be publically reported and that the companies that have been attacked are unaware of it. He added that he will notify the companies concerned as soon as his staff has identified them. 

“We have staff working around the clock to identify the victims,”
 he said. 

However, he did say that the email addresses in question are from major providers such as AOL Inc, Google Inc, Yahoo Inc, and Microsoft Corp, as well as “almost all” Fortune 500 companies and nonprofit organizations. 

Heather Bearfield, who runs cybersecurity for an accounting firm Marcum LLP, told Reuters that while she had no information about Hold Security’s findings, she believed that it was quite plausible as hackers can do more with stolen credentials than they can with stolen credit cards, as people often use the same login and password for many different accounts. 

“They can get access to your actual bank account. That is huge. That is not necessarily recoverable funds,”she said. 

The latest revelation by Hold Security comes just months after the US retailer Target announced that 110 million of their customers had their data stolen by hackers. Target and the credit and debit card companies concerned said that consumers do not bear much risk as funds are rapidly refunded in fraud losses.

The Syrian child refugee whose photo hit a nerve online #Syria

It is an everyday occurrence at border crossings out of Syria, but for four-year-old Marwan, it must have been terrifying.
After being temporarily separated from his family at the remote Hagallat crossing on Sunday, he was found by staff from the UN's refugee agency.
Andrew Harper, the head of the UN refugee agency UNHCR in Jordan, took the picture and posted it on Twitter, where it hit a nerve with many users.
It was widely reposted online.
But however heartbreaking the picture was, Mr Harper said, it was not unusual in the "chaos and confusion" of refugee border crossings.
Most refugee groups were headed by mothers bringing several children and all their possessions out of Syria, he said.
When the gates open, there is a crush as desperate refugees surge forward. Every day, children get lost.
With UNHCR staff searching for them when the surge abates, they typically do not spend too long on their own.
Mr Harper said Marwan was taken across and reunited with his mother about 10 minutes after this picture was taken.
On Tuesday, he posted another photo on Twitter that shows Marwan was at the back of a group of refugees when he was met by UNHCR staff.

"He is separated - he is not alone," Mr Harper added.
Crossing the border is a nervous time for the children and their families - one more trauma in the hellish journey from destroyed lives in Syria to an uncertain future as refugees in a foreign land.
Most of the refugees crossing at Hagallat - which lacks even a proper road - came from Homs and al-Quaryatayn, and it was likely Marwan was from there too, said Mr Harper.
He was just one of about 1,000 people who crossed into Jordan on that day alone.
There are now 600,000 Syrian refugees registered with the UNHCR in Jordan, part of an estimated 2.4 million across the region as a whole.

It is not clear what the future holds for young Marwan.
But with the mood of other refugee children one of relief once they cross the border, it is hoped that he, too, might look forward to a brighter future.
Malala Yousafzai, the teenager who survived a Taliban assassination attempt in Pakistan and has become a global campaigner for children's education, was also at the border on Sunday.
She witnessed emotional scenes at the border and, with her father, helped several refugees cross the no-man's land that separates the two nations.
The Malala Fund is teaming up with local Jordanian and Syrian organisations to help Syrian children get an education.

The Anti-Social Network

Bob Dylan once sang, “The times they are a changing.”
I once sang, “I’ve got a combine harvester, it’s made out of kitchen spoons, and that’s why you’re a poo.”

Despite Bob’s bad grammar, he had a point and, somewhere, so do I. Because if I was a 10 year-old 
in this day and age, I probably would have tweeted that beautiful nonsensical serenade, or uploaded a video of it onto Youtube.
The recent birth of my sister’s human child got me brooding over the time and age that we are in, and how, at no point in the history of our planet, have events ever been recorded 
with such personable accuracy.
I mean, if only we could look back on John Wilkes Booth’s tweets and read, “Lol your beard is well 
silly, man, Imma kill you.” Or see George Michael’s FB status as “Interested in: Men.” Everything 
would have been different.
My brother-in-law decided to set up a Facebook account for my baby niece on her first day of life, with the idea that at some point down the line – especially with the
 new FB timelines – they could pass on the account to her for her own use. She would have a log of her whole life, right there for her to see, from conception to inevitable dysfunction.
This got me thinking about one day when I poop out a little Timmy, or however that shit works. 
Would he not be curious about daddy’s wanderlusting? I dread the thought that someday, at the 
click of a button, he would know everything there is to know about me. How would my kid
 respect me after seeing me wasted in a pile of my own vomit on the floor, swearing at the camera 
with knickers round my face? “Mummy, Mummy who is that girl daddy’s with?”
I cringe at the idea of my kids going through my pseudo-diary Twitter account, piecing together who I was and who they may become. Thankfully, my tweets are made up of random, surreal thoughts 
and seem like gibberish to the naked eye so the worst they can think of me is that I had Aspergers 
or something.
But I’ve come to a little gem of a realisation. In 10 or 20 years time, when we’ve all grown up and
 had Facebook for most of our lives and then reproduce, does this mean the end of social networking? 
I mean unless you’re a fucking hippy, how do you expect to educate your kids about  right and 
wrong when their main influencers are seen doing and saying all the wrong things on a platform 
as accessible to them as a jar of cookies? This will probably lead, at some point within the next
 10 years, to a mass privatising of accounts. Once we’re done with airing our dirty laundry in our 
rebellious years, we’re going to want to neatly fold it and put it at the back of our closets, with a
 child-proof lock on the door. The less accessible information available, the less users will sign up and eventually it 
becomes the anti-social network.
Could that be the end of Facebook as we know it? Makes a bit of
 sense doesn’t it?
Then again, by then we may all be telepathically connected to the internet and each other, and you
 won’t even have to open your eyes to see my rendition of Combine Harvester.KitchenSpoons.Poo.

#Egypt’s #Muslim_Brotherhood leader says not to fast: You need your strength for battle


The Times of Israel is reporting that the spiritual leader of the Muslim Brotherhood is suspected of being behind several tweets telling members to quit fasting for Ramadan so they’ll be strong enough to battle for ousted Mohammed Morsi’s return.
