New Horizons probe captures blue skies on Pluto

New Horizons probe captures blue skies on Pluto

The spacecraft has also detected numerous small, exposed regions of water ice on Pluto.
"Who would have expected a blue sky in the Kuiper Belt? It’s gorgeous,” said Alan Stern, New Horizons principal investigator from the Southwest Research Institute, Boulder, Colorado.
The haze particles themselves are likely gray or red but the way they scatter blue light is amazing.
"That striking blue tint tells us about the size and composition of the haze particles,” said science team researcher Carly Howett.
A blue sky often results from scattering of sunlight by very small particles.
"On Earth, those particles are very tiny nitrogen molecules. On Pluto they appear to be larger -- but still relatively small -- soot-like particles we call tholins,” Howett added in a NASA statement.
Scientists believe the tholin particles form high in the atmosphere, where ultraviolet sunlight breaks apart and ionizes nitrogen and methane molecules.
The probe also spotted water ice on Pluto. “Understanding why water appears exactly where it does, and not in other places, is a challenge that we are digging into,” said science team member Jason Cook.
The areas showing the most obvious water ice spectral signatures correspond to areas that are bright red in the colour images.
"I’m surprised that this water ice is so red. We don’t yet understand the relationship between water ice and the reddish tholin colorants on Pluto's surface,” asked Silvia Protopapa, science team member from the University of Maryland.
New Horizons is currently five billion kilometres from Earth with all systems healthy and operating normally.

Don’t act so surprised, Your Highness. You weren’t on any mercy mission this time. Several transmissions were beamed to this ship by Rebel spies. I want to know what happened to the plans they sent you. In my experience, there is no such thing as luck. Partially, but it also obeys your commands. I want to come with you to Alderaan. There’s nothing for me here now. I want to learn the ways of the Force and be a Jedi, like my father before me. The more you tighten your grip, Tarkin, the more star systems will slip through your fingers.

Still, she’s got a lot of spirit. I don’t know, what do you think? What!? I don’t know what you’re talking about. I am a member of the Imperial Senate on a diplomatic mission to Alderaan– What good is a reward if you ain’t around to use it? Besides, attacking that battle station ain’t my idea of courage. It’s more like…suicide.
You don’t believe in the Force, do you? Obi-Wan is here. The Force is with him. I call it luck. Look, I can take you as far as Anchorhead. You can get a transport there to Mos Eisley or wherever you’re going. What?! The Force is strong with this one. I have you now.

She must have hidden the plans in the escape pod. Send a detachment down to retrieve them, and see to it personally, Commander. There’ll be no one to stop us this time! You’re all clear, kid. Let’s blow this thing and go home! Partially, but it also obeys your commands.
  • Dantooine. They’re on Dantooine.
  • He is here.
  • Don’t underestimate the Force.

I care. So, what do you think of her, Han? A tremor in the Force. The last time I felt it was in the presence of my old master. But with the blast shield down, I can’t even see! How am I supposed to fight? Obi-Wan is here. The Force is with him. But with the blast shield down, I can’t even see! How am I supposed to fight? You are a part of the Rebel Alliance and a traitor! Take her away!

  1. I care. So, what do you think of her, Han?
  2. You mean it controls your actions?
  3. Look, I can take you as far as Anchorhead. You can get a transport there to Mos Eisley or wherever you’re going.
  4. I’m trying not to, kid.

Revenge of the Sith

post-imageI can’t get involved! I’ve got work to do! It’s not that I like the Empire, I hate it, but there’s nothing I can do about it right now. It’s such a long way from here. Leave that to me. Send a distress signal, and inform the Senate that all on board were killed. I’m surprised you had the courage to take the responsibility yourself. No! Alderaan is peaceful. We have no weapons. You can’t possibly…
Your eyes can deceive you. Don’t trust them. He is here. What?! Hokey religions and ancient weapons are no match for a good blaster at your side, kid. I’m trying not to, kid.
I’m trying not to, kid. I have traced the Rebel spies to her. Now she is my only link to finding their secret base. He is here. You are a part of the Rebel Alliance and a traitor! Take her away! Dantooine. They’re on Dantooine.

Hey, Luke! May the Force be with you. Kid, I’ve flown from one side of this galaxy to the other. I’ve seen a lot of strange stuff, but I’ve never seen anything to make me believe there’s one all-powerful Force controlling everything. There’s no mystical energy field that controls my destiny. It’s all a lot of simple tricks and nonsense. Remember, a Jedi can feel the Force flowing through him. He is here. Ye-ha! I have traced the Rebel spies to her. Now she is my only link to finding their secret base.

Oh God, my uncle. How am I ever gonna explain this? Look, I ain’t in this for your revolution, and I’m not in it for you, Princess. I expect to be well paid. I’m in it for the money. A tremor in the Force. The last time I felt it was in the presence of my old master.
All right. Well, take care of yourself, Han. I guess that’s what you’re best at, ain’t it? Alderaan? I’m not going to Alderaan. I’ve got to go home. It’s late, I’m in for it as it is. The plans you refer to will soon be back in our hands.

WOW, Nice photo !

I need your help, Luke. She needs your help. I’m getting too old for this sort of thing. Oh God, my uncle. How am I ever gonna explain this? Hey, Luke! May the Force be with you. No!

I suggest you try it again, Luke. This time, let go your conscious self and act on instinct. Dantooine. They’re on Dantooine. You’re all clear, kid. Let’s blow this thing and go home! I’m surprised you had the courage to take the responsibility yourself. I’m trying not to, kid.

Oldest-known fetal horse fossil is 48m-year old

Oldest-known fetal horse fossil is 48m-year old

A 48-million-year-old fossil of a pregnant horse and fetus is the oldest of its kind known to science and contains unusually well-preserved evidence of tissue from the womb, researchers said Wednesday.
The fossil was discovered in Germany in 2000, but the scientific analysis was only now completed and published in the open-access journal PLOS One.
The animal was an early relative of the modern horse—known as Eurohippus messelensis—and would have been about the size of a small dog.
The fetus is about five inches (12.5 centimeters) long and is mostly intact, except for a crushed skull.
Scientists believe the mother may have died shortly before she was due to give birth, but that her death was not linked to her pregnancy.
In addition to skeletal remains, researchers “found preserved soft tissue, like the uteroplacenta and one broad uterine ligament, which may represent the earliest fossil record of the uterine system of a placental mammal,” said the study.

The finding suggests that the reproductive system of horses has changed little over the course of tens of millions of years.

Facebook to serve free internet via satellite to Africans

Facebook to serve free internet via satellite to Africans




Social networking site Facebook has announced a partnership with French satellite operator Eutelsat Communications to provide free high-speed internet to get more Africans online by next year.
Scheduled to be launched in 2016, the AMOS-6 satellite is configured with high gain spot beams covering large parts of west, east and southern Africa.
Under a multi-year agreement with global satellite communication company Spacecom, Facebook and Eutelsat will utilise the entire broadband payload on the AMOS-6 satellite and will build a dedicated system comprising satellite capacity, gateways and terminals, Eutelsat said in a statement on Monday.
In providing reach to large parts of Sub-Saharan Africa, Eutelsat and Facebook will each be equipped to pursue their ambition to accelerate data connectivity for the many users deprived of the economic and social benefits of the Internet.
“We are going to keep working to connect the entire world even if that means looking beyond our planet,” Facebook founder Mark Zuckerberg said in a blog post. The project is part of Facebook’s ambitious Internet.org project.
Using state-of-the-art satellite technology, Eutelsat and Facebook will each deploy internet services designed to relieve pent-up demand for connectivity from the many users in Africa beyond range of fixed and mobile terrestrial networks.
“Satellite networks are well suited to economically connecting people in low to medium density population areas and the high throughput satellite architecture of AMOS-6 is expected to contribute to additional gains in cost efficiency,” the statement read.
The capacity will enable Eutelsat to step up its broadband activity in Sub-Saharan Africa that was initiated using Ku-band satellites to serve professional users.
Two years ago, Facebook announced Internet.org, an effort to accelerate the rate of connectivity by addressing the physical, economic and social barriers that are keeping people from getting online.
For Facebook, this satellite system represents one of many technology investments to enable cost-effective broadband access to unconnected populations.
It plans to work with local partners across Africa to utilise satellite and terrestrial capacity to deliver services to rural areas.
“Facebook’s mission is to connect the world and we believe that satellites will play an important role in addressing the significant barriers that exist in connecting the people of Africa,” Chris Daniels, vice president of Internet.org, said in the statement.
“We are looking forward to partnering with Eutelsat on this project and investigating new ways to use satellites to connect people in the most remote areas of the world more efficiently,” he added.
According to Michel de Rosen, Eutelsat chairman and CEO, “Eutelsat’s strong track record in operating ‘High Throughput Satellite’ systems will ensure that we can deliver accessible and robust Internet solutions that get more users online and part of the Information Society.”

Mysterious place known as the Triangle of Devil

Mysterious place known as the Triangle of Devil !




The Bermuda Triangle is a mysterious place in the world , known as the Devil's Triangle . This is a region where the Atlantic Ocean as the news about the missing aircraft and surface ships could be heard .

According to the legend , many of these accidents are attributed to the very nature of any power or alien animal .

In the twentieth century, telecommunications , radar and satellite technology to reach the wreck of the event was very normal . The regions in the world at any one time was the movement of heavy commercial ships and aircraft .

Christopher Columbus was the first strange experience writing about the Bermuda Triangle . He wrote that his ship diver's horizon of light dancing in the region , saw smoke in the sky . He also mentioned the direction of the compass is not correct .

A further aspect of the mysteries of the region , a ship entered the area shortly after the devil's triangle were unable to send radio waves . Failed to communicate with the coast . Unable to determine the direction of the vanished past .

According to sources in the US Navy , the last 200 years, at least half the area of ​​commercial vessels and two aircraft disappeared forever .

Also in December 1945, the United States , five bombers were lost during training . Having lost the pilots were able to send a very low radio waves .

The radio message was repeatedly asked about her , " the intense fog . We can not see anything . Where are you going do not realize it . Save us . " The message of the US Air Force rescue team immediately headed for the region . But after a while they went missing . Even they could not get any debris .
