It is compatible with all electronic devices through 116 grams of weight and functional structure. Earlier this week, Cosmos: A Spacetime Odyssey, introduced many of its viewers to the concept of these lonely planets. In the days that followed the show’s premiere, social media sites lit up with questions from viewers wondering what, exactly, these rogue worlds are — and could there really be billions of them, as Tyson said? For now, the best methods include looking for a young rogue’s heat in the infrared, and a technique called gravitational microlensing that works well for older, cooler planets, says astronomer David Bennett of the University of Notre Dame. So far, using either method, we can’t easily detect starless planets that are smaller than a Jupiter, or at least 300 times the mass of Earth. Free-floating planet CFBDSIR 2149-0403 is the blue spot marked by crosshairs in the center of the infrared image. Anyway, early observational hints of these untethered worlds turned up in the late 1990s, when a team of Japanese astronomers found evidence for warm, planetary mass objects in the Chamaeleon cluster, about 500 light-years away. Based on comparisons between the surveys’ detection efficiency, the probability of microlensing events, and the expected amount of lensing caused by planets and stars, the team concluded that these planetary lenses were everywhere.
Since 2011, though, MOA has been hard at work analyzing larger data sets and refining estimates for how many free-floating planets populate the Milky Way.
Patrick O’Conner, the vast majority of the radiation a typical planet is subject to comes from the stellar winds of hits parent star. A rogue planet has no such star, and would be subject only to the ambient radiation of the galaxy, which, depending on where in the galaxy it is, could be much less. Even if radiation strips a rogue planet of its atmosphere, it would not affect those with subsurface oceans.
For settlers living in O’Neil-type space colonies these night worlds would be welcome sources of re-supply for volatiles.
Kyler Johnson, it only takes minutes (7 – 8) for the light from our Sun to reach the Earth not years. The only thing I don’t understand is how a rogue planet can maintain an internal heat source? Also, there is no chance of life on one of these planets, as there is no supply of solar energy.
Marc, Earth still has a hot core due to radioactive activity – we know this from volcanoes.

Every night, something unusual happens in Samuel Kimani’s home on the outskirts of Nairobi, Kenya. Samuel used to light his home with a single kerosene lamp, which filled the rooms with smoke and poor-quality light and cost $3 a week.
What we’re trying to do is find novel ways to bring solar power to emerging markets, trying to get over some of the problems that have occurred in the last ten years when people have tried to take solar into those markets.
The solar-as-a-service model plays very well in emerging countries partly because the pay as you go model is well understood; people have pay as you go mobile phones.
By providing solar we can eliminate that cost and replace it with something more modern and up to date.
What we find is that once people have solar power then it has a very dramatic effect on their daily lives. The fact that the weekly fee actually reduces users’ spend, by eliminating the cost of kerosene and charging phones, makes it much easier for us to sell into the market because we sell from the point of view of an economic proposition rather than just ‘solar-power is good’ – if you speak to someone who’s been living with kerosene for fifty years, sometimes it’s quite difficult to persuade them kerosene fumes are harmful things they don’t want to have. Approaching this as an economic proposition seems quite important to this project – it’s not charity – do you think this is the best way to approach alternative energy and development? There’s been a shift in mindset in the last ten years or so on how to support people who are at the lower end of the income scale. The question we asked ourselves was, “if solar power is so obviously beneficial, how come the world isn’t awash with it?” One of the problems with solar and characteristic of a problem with renewables in general is the need for the end user to buy the equipment up front. You said people, once they get their lamps they start to think about getting radios and TVs and the like – how does that work? We have found that people view electricity very differently to the way that we do in the developed world. Do you think that if this does scale up widely, we’ll ultimately have an off-grid, more efficient energy system in the developing world than the one that exists here? How do you plan to expand and scale up and how do you think energy use is going to expand in the developing world in the future? If you think of the rate at which mobile phones for instance penetrated developing markets, that’s the sort of dynamic that we would like to get. It is, but there are three hundred million households which don’t have access to electricity so unless you get into the millions you’re not making a dent in the problem. Simon Bransfield-Garth has 25 years global experience building rapid growth, technology-based businesses in sectors including semiconductor, automotive and mobile phones. Olivia O’Sullivan has worked for the Guardian newspaper, the Sudan team of the UN Peacekeeping Department and with the London NGO Waging Peace.
To be able to provide such a vital product that is safer, greener and cheaper is a fantastic step forward and I hope that this initiative leads to not only an increase in solar energy being used in the developing world , but also to inspire other such projects that could be as beneficial. Interestingly, this mirrors some of the efforts of NGOs, government agencies and the military to develop sustainable energy in austere locations. However, I think the most positive aspect of this is that it makes a real difference to peoples’ lives without making them more reliant on Western Aid.
The best deal would be to lower Taxes for all this is not the Roman Empire or OPEC Empire oh i am sorry i meant Persian Empire ..

Society Field Inspection 2016: Gulf of CaliforniaDescribed by Jacques Cousteau as the "aquarium of the world," the Gulf of California in Mexico is threatened by coastal development, climate change, and other human activities. Support National GeographicWe've supported more than 11,000 grants to scientists and others in the field.Learn more about our work. Two years after being discovered deep in a South African cave, the 1,500 fossils excavated during the Rising Star Expedition have been identified as belonging to a previously unknown early human relative that National Geographic Explorer-in-Residence Lee Berger and team have named Homo naledi.
With at least 15 individuals of all ages and both sexes represented, the find adds an unprecedented amount of information to our understanding of early human evolution in Africa. In addition, the absence of any other animal remains or large debris in the fossil chamber strongly suggests that these non-human beings intentionally deposited their dead within this cave. As a single snapshot of space history, this mosaic represents the first attempt in putting together the global appearance of Jupiter's volcanic moon Io from individual Voyager 1 1979 flyby images.
On August 28, NASA's Solar Dynamics Observatory captured a solar tempest, which looked like giant arches of hot plasma erupting from the sun's surface. An August 24 photograph taken from the International Space Station showcases a late-summer "whiting event" washing over Lake Ontarioa€” one of North America's Great Lakes.
The Earth-observing satellite Landsat 8 snapped this image of Indonesia's highly active volcanic Paluweh Island (map) on September 8.A trail of smoke stretching over the ocean and gray, scarred swaths of land in the northwestern part of the island are what's left from a deadly eruption and pyroclastic flow that descended from the summit of the volcano and killed five people on August 10. New research suggests that limiting warming to 1.5 degrees instead of 2 degrees can dramatically reduce the impacts of climate change around the world.

They have neither sunrises nor sunsets, because unlike the planets we’re more familiar with, these lonely worlds aren’t tethered to a star. Other teams soon reported more rogue candidates, in a cluster near the star sigma-Orionis, in the Orion nebula, in the Taurus star-forming region.
A microlensing study published in Nature suggested the Milky Way contains at least 400 billion star-less worlds, that the lonely planets are more common than stars like our sun. Despite careful work by the authors, it’s still possible the objects detected are just very far from their stars, that they’re brown dwarfs (a type of low-mass pseudo-star that failed to ignite nuclear burning in its core), or that the galactic population estimates are off. So far, Bennett says, new estimates appear to support the original finding that these rogue planets are really common. Astronomers suspect that many free-floating planets are wandering through interstellar space because they’ve been kicked out of their home stellar systems.
Theories describing the early solar system don’t really work unless a fifth giant planet – another Uranus or Neptune – were present at the start (one of the problems with these models is that Earth sometimes ends up running into Venus, which we know didn’t happen).
This part of the narrative echoes a paper published in 1999 by Caltech planetary scientist David Stevenson, who considered how Earth-mass planets cast from their solar systems might fare in outer space. So if a rogue planet passed in between the sun and Earth right now, you wouldn’t be able to see the affect of the planet at that moment?

With his low income, Samuel could support his family, but he wasn’t able to make long-term investments in other systems to light his home. Eight19 takes its name from the time it takes sunlight to reach the earth – eight minutes and nineteen seconds.
This allows us to create what we call “pay-as-you-go solar.” So just in the same way as you buy a scratch-card for your mobile phone every so often, you buy a scratch-card which enables your solar power to work for a period of time – for example a week or month, whatever it may be.
But also because we’ve eliminated the upfront cost of buying a solar light, so we can give people an economic return on a day by day basis.
For example, in Kenya people are spending the equivalent of about 12 dollars a month for kerosene and for charging their mobile phone.
The light doesn’t just allow them to cook but it allows things like children to do their homework. But if you say to someone who spends a quarter of their income on energy that they can halve their energy bill, then all of a sudden that has a direct impact – then after that they see the benefits of solar. There was a tendency years ago to dive in with the grand gesture –provide a tractor in Africa and so on – and the problem with that is it comes out of context, it doesn’t come with all the infrastructure that’s needed to support it and we saw many examples where the equipment breaks down and that’s the end of it because there isn’t anybody to maintain it and no spare parts.
Normally, to use electricity I don’t expect to have to buy my own small power station – but with renewables that’s exactly what we expect. They’d like to have TV, radio, internet and a computer, fridges – all the other things that everybody else would like to have. In the West, we’ve been brought up with the idea that electricity is relatively cheap so we use it in pretty inefficient ways – a great example is if I want to make a cup of coffee in the morning, then somebody over in a power station takes some fossil fuel which they burn to heat water, to drive a turbine, to generate electricity, to go a long way down a cable to warm up water to make my cup of coffee. And our vision is that these products will grow with the dynamics of consumer electronics, rather than the dynamics of alternative energies.
So our goal is to have tens of thousands of customers this year, hundreds of thousands of customers next year and millions of customers the year after.
One of the things that we see is the transformational change that you get when people have access to this power, it’s not just a case of saving money but it enables people to do things that they previously couldn’t, because they have access to information, to media and to light.
His career includes 7 years at Symbian, the phone OS maker, where he was a member of the Leadership Team and VP Global Marketing. With the environment the way it is going we are not able to underestimate any item that presents totally free power at no cost to both the consumer and more importantly the world! When the International Energy Agency met to discuss the future of solar energy is said that it would lead to massive long term benefits and change energy consumption around the world. Also Solar is used by the farmers to re-charge batteries to power LED lighting at night so their children can read. The TAX that all Governments Federal, State, County and City put on everything they can thing of. Making it a Heavy Burden on many that are already struggling just to put food on the table.

To learn firsthand what's going on in and around this marine treasure of global importance, the National Geographic Society sent its top scientists and officials to the region in January 2016.
While the public has seen the computer-processed composite photos of the moons of Jupiter, the above illustration offers a peek at how the mission scientists first attempted to fit together, like puzzle pieces, A individual detailed images beamed back to Earth from nearly 600 million miles (965 million kilometers) away. Such events occur when changes in water temperature and acidity in late summer cause fine particles of calcium carbonate to form, making the water turn milky in appearance, as seen here from orbit. Blanco Telescope at the National Science Foundation's Cerro Tololo Inter-American Observatory in Chile.The survey will snap color images of more than 300 million galaxies and 100,000 galaxy clusters as far as eight billion light-years away.


At the same time, it provides power for digital cameras, PDA, portable DVD players and other digital devices. The two most well-known ways of finding exoplanets rely on telltale signals coming from the planets’ stars – either wobbles caused by the gentle tugs of an orbiting planet’s gravity, or the slight dimming produced when a planet passes between Earth and its star. If a massive object – say, a rogue planet – passes between a star and Earth, the planet can act as a lens, curving and tweaking the star’s light as seen from Earth. More recently, in 2012, astronomers described a hot (700 degrees Celsius) homeless planet, clunkily named CFBDSIR2149-0403, just 100 light-years away.
Data from two microlensing consortiums, known by the acronyms OGLE and MOA, pointed toward 10 possible free-floating planets, spotted over a two-year-long survey aimed toward the Milky Way’s galactic bulge. And, there are hints that we may soon be able to find smaller, untethered planets about the mass of Neptune – much too small to be mistaken for a failed star.
This process tends to happen early in a system’s history, says astrophysicist Greg Laughlin of the University of California, Santa Cruz.
Later, as the planets begin to migrate, that fifth giant is kicked out of the solar system and sent flying into space. Stevenson suggests that if these planets retained a hydrogen atmosphere, they could stay warm enough to have liquid water on their surface. A metal core must surely need another gravitational force to maintain its rotation, thereby producing a magnetic field and defense against deadly radiation. Deep in the depths of the Earth on the sea floor there are colonies of life that exist without light so yes there could be life on such planets. Their family supports itself day-to-day through their main source of income, their cow Baraka, whose milk is collected daily and sold directly to customers for about $1.80 a day.
That is, until he became the first person in the world to use the IndiGo pay-as-you-go solar energy system. Where people don’t have electric light their options are kerosene or in some cases candles – about 80% of Zambia uses candles – and in South Sudan, for instance some people even just use grass as a way of lighting their houses.
We’re providing the IndiGo solar energy system for just over a dollar a week, so effectively for five dollars a month the user is getting light for two rooms and also power to charge a mobile. We have a firm belief that sustainable technology needs to have a sustainable business model – so as far as possible what we try to do is to build a local economy around the technology. We wanted to create a kind of a journey to help people extend their use of electricity, so we came up with this idea of the “energy escalator.”  If you imagine a rural family in, say, Malawi – we provide a couple of lights and the ability to charge a phone. One of the assumptions prevalent about ten years ago was that the grid would eventually reach everyone.
So a really simple example of one of the things that people do with mobile phones – people can move from just growing subsistence crops to having market information, market prices so they can grow more in the way of cash crops, and get involved in much more energetic economic activity.

Some wicked in Government have been backing Coal, Oil, Gas and the Nuclear industries for too many years. All the Governments of the World now know it is wise to use Renewable Energy it is the Local Governments that are a little slow to learn what is best for all not just there pocket book.
They toured the desert islands off the southeastern coast of the Baja Peninsula and they listened to presentations by more than a dozen experts, including several whose Baja California research is funded by the Society.
This object, which appears as a faint blue dot at the centre of the picture and is marked with a cross, is the closest such object to the Solar System. As planets in young systems settle into their orbits, their gravitational jostling can end up sending a sibling or two into space.
A double planetary system, or a planet with one or more large satellites may fullfill this criteria.
Their township has few amenities and grid electricity is available only to the few who can afford it. Samuel purchased the system for an affordable $10 and now activates it automatically with a $1 scratch-card each week.
The amount of money people spend on kerosene for lighting is huge – about 38 billion dollars. So we’ve roughly halved people’s energy spend and we’ve given them the benefit of solar power instead of kerosene. As you provide more power, you enable other things – such as access to a radio or a television – and so what the electricity is doing is providing key things that we’ve come to value in the more developed world like access to information and access to media; both of which have an important social impact, including the ability to participate in the political process. Where we’re rolling out lights, we have local maintenance, local distribution, local marketing, and so on. Whereas for off-grid customers, nobody would dream of using electricity to boil water, electricity’s far too valuable to use for that; you use electricity because it gives you information, it gives you communication, it gives you light – it’s a very valuable commodity. But the cost of extending the grid to rural areas is very high and today power can be delivered more cost-effectively using renewables, generated locally.
In a sense it’s a way of helping people get into the information age without having to go through the industrial revolution. And, larger planets are generally warmer than smaller planets, says Stevenson, who calculated that a cast-off Jupiter would only cool by about 15 Kelvin at its surface. Light travles at about 186,000 miles per second so no its light does not take years to reach us – it is in minutes.
Through IndiGo, Samuel’s small home now has two bright lights providing eight hours of light each evening, which enables the kids to study in the living room whilst Mary prepares food in the kitchen.
When you compare the cost of that kerosene light for light with mains electric lighting, the light out of a typical kerosene lamp costs between a hundred and a thousand times as much – just because it’s a very inefficient lamp and kerosene’s expensive. This is directly analogous to mobile phones which have removed the need to extend landlines into rural areas. When we did our first trial of 30 units in South Sudan, a queue formed of people standing there with their ten dollars saying ‘I want my light please’ and we had to say ‘sorry, we’ve only brought 30 this time’ and they were quite upset because they wanted their light! In visible light the object is so cool that it would only shine dimly with a deep red colour when seen close-up. In any case of such a panet were to pass between Earth and ths sun it would disrupt our orbit and end all life here – so we would notice it erm for a short time!.
So you end up with a situation where the people who have the least income in the world are paying not just a bit more for their energy but vastly more for their energy. In Africa if someone wants a reasonable home lighting system, the cost starts at about fifty dollars – in terms of proportion of salary, that’s roughly the equivalent of buying a car in the West. IndiGo enables the end user to fund the infrastructure, using the premium they were previously paying for kerosene, in order to get their own power generation without the up-front cost.
It’s just about providing a mix of technology and business model that enables things to move forward.
The IndiGo system addresses that by providing solar as a service with a very small initial cost. We can afford to charge a little bit more because the customer has just saved 100 dollars or so over the previous 18 months compared with what they would have spent on energy. This is readily understood –  people just seem to intrinsically get what we’re trying to do.
And then that pays off after a period of time, so you go onto the next step, maybe powering a television.
And so, over a period of time a rural customer transitions in steps from no electricity to still being a rural farmer, but now having many of the benefits of electricity.
