VY Canis Majoris is a red supergiant star located in Canis Major constellation. This star is the biggest and brightest known to humankind.

Star was discovered in 1801 by french astronomer Jerome Laland. VY Canis Majoris is in our Milky Way, 4892 light years from Earth. Its radius is 1500 times bigger than Sun’s and it could fit inside million Earth planets. Furthermore, supergiant’s diameter reaches 2,4 million kilometers. If this star would replace the Sun, it would reach Saturn’s orbit. In addition, this star’s mass is bigger than the Sun’s only by 10-25 times. Its surface reaches 3200 °C while Sun’s surface 5600 °C. Star is brighter than Sun around 250 000- 500 000 times.

Supergiant star is very rare in our galaxy. To tell the truth, most stars in our galaxy are smaller than the Sun. Big stars burn their energy really fast and die after few million years. In comparison, smaller stars, like our Sun, counts their age in billion years.

Scientists calculated that VY Canis Majoris already burnt about half of its mass and that its age reaches around 10 million years. That leads to the conclusion that this star will blow up and become supernova in 100 000 years time. After star blows up it will probably form a black hole.

Nokia 3310 is making a comeback!

_3

Nokia is going to bring back the historic 3310 in the biggest tech comeback of all time. A homage to the Finnish giant’s classic feature phone will reportedly be released later this month when HMD unveils its new range of Nokia branded devices at Mobile World Congress.

The Nokia 3310, which was first released in 2000, was beloved for a days-long battery life, ability to withstand great falls, and the classic game Snake.

The nostalgia-inducing phone, which hasn’t been available for some years, will probably get a refresh, although it is not entirely clear how modernised it will be. Furthemore, The updated Nokia 3310 will cost €59 and is designed to be a second phone.

There are few details about the new phone’s features and how it will work. The original Nokia 3310 could make calls and send text messages, but didn’t have a camera and couldn’t connect to the internet. But it was renowned for being indestructible and having a seemingly endless battery life.

While the 3310 isn’t Nokia’s best selling phone of all time, it is one of the most iconic. It sold more than 126 million units and its sturdy design meant many first time phone owners kept it for years.

Mission for moon rocks

christmas2015fullmoon

China will launch its next lunar mission in November this year. Chang’e-5 will attempt to retrieve samples of moon rock and return them to Earth. If the mission succeeds it will be the first lunar sample return since the Soviet Union’s Luna-24 in 1976.

The mission will be China’s most ambitious moonshot to date. Weighing in at 8.2 tonnes, the spacecraft will be launched by China’s Long March 5 rocket. This heavy-lift vehicle is one of the most powerful launchers in the world. Its maiden flight took place on 3 November 2016.

The spacecraft will consist of four distinct parts: a lander and an ascender, an orbiter and a returner. The lander will descend to the surface of the Moon, collect the samples and place them in the ascender. This will launch and rendezvous with the orbiter and returner, all of which will then journey back towards Earth.

The samples will be transferred to the returner, which will detach from the orbiter and re-enter the Earth’s atmosphere. In 2014, China tested the returner technology by dropping a capsule from Earth orbit to Inner Mongolia.

Chang’e-5 will be China’s fourth lunar mission. Beginning in October 2007, China have launched two lunar orbiters and a lander that carried the rover called Jade Rabbit. A second rover mission, Chang’e-4, is scheduled to land and operate on the Moon’s far side in 2018. If successful, it will be a world first.

Top 10 revolutionary scientific theories

Why-the-Heck-Do-We-Need-Scientific-Theories-Anyway-471119-2.jpg

Most scientific fields have been made over with a revolutionary theory at least once in recent centuries. Such makeovers reorder old knowledge into a new framework. Revolutionary theories succeed when the new framework makes it possible to solve problems that stymied the previous intellectual regime.

10. Information theory: Claude Shannon, 1948
It’s not exactly the most revolutionary theory, since there really wasn’t a predecessor theory to revolutionize. But Shannon certainly provided the mathematical foundation for a lot of other revolutionary developments involving electronic communication and computer science.

9. Game theory: John von Neumann and Oskar Morgenstern, 1944 (with important embellishments from John Nash in the 1950s)
Developed for economics, where it has had some successes, game theory didn’t quite completely revolutionize that field. But it has been widely adopted by many other social sciences. And evolutionary game theory is an important branch of the study of evolutionary biology. Game theory even applies to everyday activities like poker, football and negotiating for higher pay for bloggers.

8. Oxygen theory of combustion: Antoine Lavoisier, 1770s
Lavoisier did not discover oxygen, but he figured out that it was the gas that combined with substances as they burned. Lavoisier thereby did away with the prevailing phlogiston theory and paved the way for the development of modern chemistry. It was a much safer revolution for Lavoisier than the political one that soon followed in France, so revolutionary that Lavoisier lost his head over it.

7. Plate tectonics: Alfred Wegener, 1912; J. Tuzo Wilson, 1960s
Wegener realized that the continents drifted around as early as 1912. But it wasn’t until the 1960s that scientists put the pieces together in a comprehensive theory of plate tectonics. Wilson, a Canadian geophysicist, was a key contributor of some of the major pieces, while many other researchers also played prominent roles.

6. Statistical mechanics: James Clerk Maxwell, Ludwig Boltzmann, J. Willard Gibbs, late 19th century
By explaining heat in terms of the statistical behavior of atoms and molecules, statistical mechanics made sense of thermodynamics and also provided strong evidence for the reality of atoms. Besides that, statistical mechanics established the role of probabilistic math in the physical sciences. Modern extensions of statistical mechanics  have been applied to everything from materials science and magnets to traffic jams and voting behavior.

5. Special relativity: Albert Einstein, 1905
In some ways special relativity was not so revolutionary, because it preserved a lot of classical physics. But come on. It merged space with time, matter with energy, made atomic bombs possible and lets you age slower during spaceflight.

4. General relativity: Einstein, 1915
General relativity was much more revolutionary than special relativity, because it ditched Newton’s law of gravity in favor of curved spacetime. And opened scientist’s eyes to the whole history of the expanding universe. And provided science fiction writers with black holes.

3. Quantum theory: Max Planck, Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Max Born, Paul Dirac, 1900–1926
Quantum theory ripped the entire fabric of classical physics to shreds, demolished ordinary notions of the nature of reality, screwed up entire philosophies of cause and effect and revealed peculiarities about nature that nobody could ever have imagined.

2. Evolution by natural selection: Charles Darwin, 1859
Darwin showed that the intricate complexity of life and the intricate relationships among life-forms could emerge and survive from natural processes, with no need for a designer or an ark. He opened the human mind to pursuing natural science unimpaired by supernatural prejudices. His theory was so revolutionary that some people still doubt it.

1. Heliocentrism: Copernicus, 1543
One of the greatest insights ever, conceived by some ancient Greeks but established only two millennia later: the Earth revolves around the sun. It’s Number 1 because it was the first. Where did you think word revolutionary came from, anyway? It was only rarely used to mean what it does today before Copernicus put revolutions in the title of his revolutionary book.

NASA approves a mission to look inside a black hole

supermassive-black-hole-x-ray-jet.jpg

Neutron stars, black holes, and other remnants of stellar explosions are some of the universe’s most intriguing objects – and some of the hardest to study. But when NASA’s newest Explorers Program mission, IXPE, launches, we’ll see them like never before.

Stellar remnants such as black holes and neutron stars are difficult to see. Because of their tiny size and oftentimes obscuring disks of dust and gas, direct measurements of these objects have long eluded astronomers. However, such extreme objects heat their environments to millions of degrees, which causes high-energy emission in the form of easily-observable X-rays. Studying these X-rays provides a window into the world around otherwise impossible-to-see phenomena.

Now, NASA plans to delve deeper into black hole and neutron star X-ray emission with the newest addition to its Explorers Program mission lineup: the Imaging X-ray Polarimetry Explorer (IXPE). Led by Principal Investigator Martin Weisskopf at NASA’s Marshall Space Flight Center, IXPE will include three space telescopes capable of measuring the polarization of X-rays coming from the environments around objects such as neutron stars, pulsars, and black holes. Polarization is a property of light, including X-rays, that describes the direction in which the electromagnetic wave “points.” Although not recorded by most conventional instruments, polarization offers unique information about the source of the observed light, including geometry, magnetic field, and emission mechanism. Measuring the polarization of X-rays emitted in the environments of neutron stars and black holes can thus help astronomers characterize the magnetic fields of these objects, as well as the structure and geometry of the accretion disks and jets that form around them. This information will provide yet more pieces to the puzzle of how these amazing objects look and behave.

NASA’s Explorers Program provides selected mission proposals with the opportunity and funding to perform science from space. Unlike major space-borne observatories such as the Hubble Space Telescope and the Chandra X-ray Observatory, Explorers missions are small- or medium-sized projects characterized by more moderate price tags and a shorter timeframe between concept and launch. Some of the program’s current ongoing missions include the Widefield Infrared Survey Explorer (WISE) and the Swift Gamma Ray Burst Explorer (Swift). IXPE will be joining upcoming Explorers missions that include the Ionospheric Connection Explorer (ICON), projected to launch in June of 2017, and the Transiting Exoplanet Survey Satellite (TESS), with a scheduled launch date in December of 2017.

According to NASA’s press release, IXPE is currently set to launch in 2020 with an estimated total cost — including the mission’s launch vehicle and post-launch operations and data analysis — of $188 million. By comparison, NASA’s flagship X-ray telescope, the Chandra X-ray Observatory, cost $1.65 billion in development alone and another $350 million simply to launch.

Earth is bombarding the moon with oxygen

013017_ts_lunar-oxygen_main_free

Life on Earth may have made its mark on the moon billions of years before Neil Armstrong’s famous first step.

Observations by Japan’s moon-orbiting Kaguya spacecraft suggest that oxygen atoms from Earth’s upper atmosphere bombard the moon’s surface for a few days each month. This oxygen onslaught began in earnest around 2.4 billion years ago when photosynthetic microbes first flourished, planetary scientist Kentaro Terada of Osaka University in Japan and colleagues propose January 30 in Nature Astronomy.

The oxygen atoms begin their incredible journey in the upper atmosphere, where they are ionized by ultraviolet radiation, the researchers suggest. Electric fields or plasma waves accelerate the oxygen ions into the magnetic cocoon that envelops Earth. One side of that magnetosphere stretches away from the sun like a flag in the wind. For five days each lunar cycle, the moon passes through the magnetosphere and is barraged by earthly ions, including oxygen.

Based on Kaguya’s measurements of this space-traveling oxygen in 2008, Terada and colleagues estimate that at least 26,000 oxygen ions per second hit each square centimeter of the lunar surface during the five-day period. The uppermost lunar soil may, therefore, preserve bits of Earth’s ancient atmosphere, the researchers write, though determining which atoms blew over from Earth or the sun would be difficult.

 

Leaked Samsung Galaxy S8

Untitled.png

In the tech world, everyone is talking about Samsung’s new flagship – S8. The web and tech reviewers content are filled with Galaxy S8 rumors and it’s image leaks. Well, usually it’s an insider that shares about devices early, but maybe Samsung had done it already. Samsung may have inadvertently revealed the Galaxy S8’s design or maybe two versions of it.

Samsung had worked determinedly every time when it comes to its ‘Galaxy S’ series. Two official videos released by Samsung show the design of Galaxy S8. This device is expected to launch within next few months.

While advertising it’s Super AMOLED Display technology, Samsung used a reference device which was similar to one we see in rumors. Social media is going crazy as everyone wouldn’t expecting Samsung to expose the Galaxy S8 itself. Addidtion to this, if rumors comes true, then S8’s design will be very different from the Samsung devices we’ve seen so far.

Well, there are so many things or maybe clues in the video which are making us believe that the device is S8. First, we see the screen-to-body ratio is extremely small. Both left and right side have virtually no border. Meanwhile, thin borders are present at the top and bottom for feeding it’s logo and sensors. As we even written in one of our articles, physical home button is missing.

This new flagship is expected to launch in April. A little bit delay due to problems of Galaxy Note 7. As Galaxy Note 7 didn’t stay in the race, then Samsung may put every single effort in this device.

The Best Smartphone in the World?

turingphonefront-932x583-435x295

Turing Robotic Industries (TRI) is a mobile manufacturer company which uses a decentralized authentication method to make mobile. They make more enhanced smartphones than normal smartphones. Now they have come with an awesome device which has incredible features.

The Android Police wrote that in a mailing list report, TRI has declared about their Turing Phone Cadenza and told that this will be the finest smartphone ever made. The CEO and Chief Architect of the company Steve Chao declared their upcoming smartphone is the work of TRI to put together the AI keen on smartphones.

They said that Cadenza will be launched in 2017. The features and the specifications of the phone are mind boggling as the company declares their device as the best smartphone in the world.

The model of Turing Phone Cadenza is overwhelming. It is power-driven by two Snapdragon 830 SoCs processors. It will have 60MP “Imax 6K Quad Rear Camera, Triplet Lens/T1.2”, a 20MP dual front camera and 12GB of DDR4X RAM. It will also include 512GB of internal storage with two MicroSD drop in, a 100Wh battery capacity with graphene and hydrogen fuel cells (lolwut), and will support four nano SIMs.

Turing Phone Cadenza will operate on Swordfish OS. Sailfish OS assures highly developed AI supported by surrounded characteristics which consist of a memory network and a neural network. The price of the device is yet not revealed.

Let’s see, if the phone will have all the above specifications when launched in the market. If this will actually happen then this will be the greatest achievements of the Turing Robotic Industries.

CES 2017: Winners and losers

maxresdefault-1

LAS VEGAS — CES is more than just a showcase of what the latest technology has to offer — it’s a cage match of competing tech trends. The gadgets and technologies we’ll be using tomorrow battle it out for our money and attention, and when the dust clears some inevitably come out on top.

This year’s CES had a lot to say about smart homes, self-driving cars, laptops and more. There’s a lot to be excited about in all those categories, but sometimes such rapid progress can leave some people behind. Here are the winners and losers of CES 2017:

WINNERS

Amazon

Anyone building a smart-home gadget couldn’t wait to tout its compatibility with Alexa, Amazon’s cloud-based digital assistant. Everyone saw that trend coming, but it was surprising just how powerful Alexa’s draw was — even brands who don’t make smart devices were excited to offer products, like wireless speakers, bundled with an Echo or Echo Dot. Amazon may be the most influential brand at CES 2017 to have no official presence on the show floor.

Minimalism

TVs have been thin for a long time, but not this thin. LG’s Wallpaper TV is so thin that it makes an iPhone look fat. Thanks to OLED tech, which has self-illuminating pixels, the panels can literally be paper-thin, and they’re light, too — the 77-inch model weighs just 27 pounds. LCDs are pretty austere, too, with super-tiny bezels now the norm. And short-throw projectors and transparent displays are making the TV disappear altogether.

Laptops

In contrast to TVs, laptops are getting big again. Models from Razer, Lenovo, Acer and others prioritize performance and gimmicks over form factor. Virtual reality is partly to blame for this trend — if you need massive graphics power, it’s hard to build a slim computer. But there’s also a renewed sense of experimentation, with Razer’s three-screened Project Valerie and Acer’s beast of a laptop with a curved screen turning heads for their strange designs. If you want one of these, be sure to hit the gym

Personal health

CES had its share of ridiculous wearables, certainly. But many of the single-purpose health gadgets — like smart hearing aids and noninvasive blood analyzers — could really help people with specific conditions. And after you get past the oddness of devices like a smart breast pump, you can appreciate just how useful it could be to new moms. The rise of “treatables” is a trend worth getting behind.

LOSERS

Everybody who isn’t Amazon

Remember when Apple HomeKit was the sexy smart-home tech? Neither do most of the manufacturers in the field, it seems, as few — if any — played up their devices’ compatibility with Apple Home. Google Home wasn’t much of a presence either, although it’s early days for that platform and it wasn’t entirely absent. Other players are still around, but it seems Alexa has a monopoly on all of the momentum.

Phones

The smartphone is still the gateway to our digital lives, but you’d never know it from looking at CES 2017. Almost no major phone announcements happen at CES anymore, with Huawei boldly making an exception this year. Whether it’s market consolidation, slowing upgrade cycles or just a down year, mobile wasn’t part of the conversation at CES.

Privacy

Smart devices, often powered by AI, can create amazing experiences, but by their nature, they need to gather data about you, and that data can sometimes end up serving a different purpose. Whether it’s marketers wanting to sell you something, or worse, hackers wanting to steal your identity, the information from your smart gadgets is a target — one that didn’t exist before. As the Internet of Things gets more things, guarding your data is more important than ever.

 

Major freeze in Europe

snow-1209786_1280

A warm, freshwater mass rises and moves north across the Atlantic Ocean.

It’s headed toward the Arctic. There, frigid winds will scrape heat and liquid from its surface and it will sink, colder, saltier, and denser to the ocean bottom — and begin a slow journey back toward the lower latitudes, sliding under more warm water headed north.

All that heat scraped from its surface reshapes the local climate. It enters the atmosphere of the North Atlantic, slow-cooking the weather of places like Iceland, Britain, and northern Europe. That’s a big part of the reason those regions are, if not toasty, livable.

The cycle of fresher, warmer water moving north over southbound saltier, denser, colder water in the North Atlantic is called the AMOC (or Atlantic Meridional Overturning Circulation). It’s part of a complex, three-dimensional global system, driven by differences in salinity, density, and temperature, that circulates heat and matter through the world’s deep oceans.

It’s also changing. In a trend dating back to 2004, the AMOC has declined to about two-thirds of its former strength, which may have lead to some harsh winters in the UK and western Europe. A few scientists have even raised the spectre of a total AMOC collapse — a paradoxical warming scenario that would lead to far-harsher winters and expanding ice sheets in the North Atlantic. It would be a paradoxical, but not impossible, consequence of a warming climate.

In a paper published in Science Advances, Yale geophysicist Wei Liu and his coauthors demonstrate what they say is a significant bias in existing climate models toward AMOC stability, and show how increased heat and CO2 in the atmosphere could directly lead to AMOC collapse.

The result? Even as the rest of the world heats up, parts of Europe could see significant annual cooling over a period of several hundred years.

Liu cautions that this finding is still based on a single model. Rather than work from a steady increase in CO2 over a period of decades, he and his coauthors used a simple doubling of C02 all at once, after which it remains constant in the atmosphere.

That’s a rougher model, but its results are significant enough to point the way toward future research. Liu said the next step for researchers is to run similar experiments across a diverse range of complex models. More model data will shine a brighter light on just how likely a total AMOC collapse is, what regions would be impacted, and how soon it could happen.
