Voyager 1, NASA does not know where it is

In March of this year, 35 years have passed since the Voyager 1 spacecraft has been sent into space, leaving its mission to leave our solar system and explore interstellar space. That was the original premise, but NASA admits that it has no idea if it was successful.

The probe is the furthest, still acting object sent into space by man. The NASA-based Jet Propulsion Laboratory claims that Voyager 1 has gone to completely unknown territories, but the original mission team questioned this claim, saying that Voyager 1 is still within the Solar System. Since that time, the debate has been steadily increasing, and more and more scholars are starting to take part.

This week saw new findings from researchers at the University of Maryland and Boston University suggest that Voyager 1 entered the interstellar space on July 27, 2012. NASA confirms that there are many contradictory theories about the location of the probe, but she admits that she has no idea where she may be at the moment.

The space agency explains that the discrepancies in opinion come from the way scientists define the boundaries of our solar system. They claim that the boundary defines the magnetic field of the Sun and call it a “solar bubble”. The area beyond the magnetic field of our star is what scientists consider to be interstellar space, which has its own magnetic field.

Launched in 1977, the Voyager 1 probe monitors the magnetic field emitted by the Sun. The Jet Propulsion Laboratory counted that the probe passing through the solar bubble to the interstellar space would notice a distinct change in direction. Meanwhile, scientists say that the rotation of the solar system and interstellar space is in the same direction, so the transition may not be noticeable.

NASA has sparked a fire in space

The US space agency has just announced a test of fire control in space just weeks before. On board the Cygnus ferry returning to the Earth, the flames of cotton fiberglass were set on fire to see how the fire would behave in microgravity.

In a few years NASA wants to send a manned mission to Mars. The journey will take many months, during which many things may go wrong. The greatest fear of engineers and astronauts is of course a fire on board a spacecraft, so NASA wants to do it right now.

A firefighting experiment, launched within a project called Saffire-I, was announced a few weeks ago. The fire was brought on board Cygnus, who at the end of March provided supplies to the ISS.

The NASA Glenn Research Center, specifically for the purpose of the experiment, has developed an additional module that protected the ship from the spread of flames. A few hours after Cygnus’s disconnection from the ISS, a glass fiber block of 41 x 96 cm was set on fire, which spontaneously burned out after the ship had overcome a distance of several thousand kilometers.

NASA will look for a twin of land

Kepler’s telescope, which has searched the cosmic sphere, has found many promising exoplanets in which conditions can be found for the development of life. Now NASA wants to gather some tools to find promising planets and plans to send a special satellite for this purpose.

The population of our planet is getting bigger, natural resources are closing at a rapid pace and in a while you will have to look for a new home where humanity can continue to grow. NASA using the Kepler telescope has been looking for such a home for several years and found some promising planets. The telescope can, however, explore only a particular segment of the cosmos, and for a broader search one needs something else.

NASA is working on a TESS (Transiting Exoplanet Survey Satellite) satellite that will search for life-changing planets. The device observes stars and searches for the shadows of planets orbiting on their background. Then he will calculate the size of the planet and the length of its orbit, so that the scientists will determine whether the object is suitable for habitation.

A real light sword? All hope in science

What exactly is a light sword? To sound scientifically, it would be easiest to say that his blade is a form of concentrated energy stored in the force field. This obviously does not explain because, at least now, we can not do this type of construction. But maybe?

The sword, which is illuminated by the color of the blade, is able to cut everything apart from the blade of another light sword is the dream of many Star Wars fans, but if such a weapon was indeed created, they would certainly be interested not only in gadgets. Is it possible at all? It turns out that in theory yes, although a real light sword, which functions to correspond to this film, would have to visually slightly differ from it.

Probably the most popular belief in light swords is that their blade is a laser. Despite the visual similarity and the fact that lasers are actually used for eg cutting complex shapes from sheet metal sheets, the basic aspects such as the fact that the laser beam that is not absorbed or reflected will continue indefinitely, the bright color visible only in Darkness, the two beams in the event of a collision just to penetrate, quickly crossed this hypothesis.

The light-emitting glow of the sword could be created using a plasma. Ionized matter, which we observe even when looking at neon light, can also handle most materials, which is used in plasma burners.

The stream from the burner, despite its limited length, would be far to the slender Jedi’s sword blade, so it would be necessary to use an electromagnetic field, in addition to keeping the hot rays away from the hand of the knight.

So we have an effective blade, however, which can not, however, pair up another blow. So you need a hard core capable of withstanding extreme temperatures. This limits the choice to … pottery. To make the design meaningful when the sword is turned off, the ceramic core would have – like many toys pretending to be luminous weapons – a telescopic structure that hides in the handle.

Finally, there is the problem of powering the device with energy that could be stored in the handle. Without going into details, it can safely be assumed that sufficiently destructive sword blade power will reach around 20 MW, which would be sufficient to feed a small town.

The lightest ultrabook in the world

If it seems to you that your brand new laptop can not be thinner and lighter, you probably have not seen the NEC model. LaVie Z weighs only 875 grams, which is two times less than the average ultrabook. The computer has a pretty big 13.3-inch screen and the latest Intel Core i7 processor. Can you want more?

NEC LaVie Z showed up at this year’s Intel Developer Forum in San Francisco, home to the Engadget team. Maybe the film and photos that it has shot will not let you feel the lightness of your computer, but it will show its small thickness. Quite to say that its magnesium housing is only slightly thicker than the USB port, and the display looks like a thin plate, not a screen resolution of 1600 x 900 pixels with LED backlight. The whole is only 15 mm thick.

At the heart of the computer is an Intel Core i7-3517U dual-core processor clocked at 1.9 GHz (Turbo 3 GHz), integrated Intel HD Graphics 4000 graphics, 4 GB of RAM, 128 GB SSD, SD slot One USB 2.0 port and one 3.0 port and full-size HDMI output. It is a shame that there is no battery information, but one can expect that the extreme slimming of the computer has resulted in rather a small capacity.

LaVie Z will go first to the Japanese market and it is not known whether NEC will launch it in other countries. Would you choose such equipment, even if it would cost far more than the already expensive ultrabooks?

Astronomers have observed a giant supernova explosion

The gigantic and brightest of the stars so far detected, so-called. The supernova, detected an international team of astronomers – reported in his latest issue of the journal “Science”.

The explosion was so powerful that it would easily overwhelm the entire Milky Way galaxy in which the Solar System is located. A gigantic explosion occurred – according to preliminary estimates – in a galaxy 3.8 billion light years from Earth.

This extraordinary phenomenon was observed in the ASASSN (All-Sky Automated Survey for SuperNovae) program last year with a network of telescopes all over the Earth. According to “Science” this was “the most powerful supernova explosion ever observed throughout human history.”

The explosions of supernovae, massive and extremely massive stars torn by internal forces, which appear to be stronger than gravity trying to prevent them, are rarely observed.

The supernova explosion is usually 20 times brighter than the light emitted by the average spiral galaxy, which includes the Milky Way. Sometimes the explosion is 50 times brighter, which is 570 billion times brighter than our sun.

The last explosion that was named ASASSN-15lh was twice as strong as the previous record.

One of the astronomers participating in the project, Sobo Dong from Peking University, said he was so fascinated by the phenomenon that he “could not sleep all night”.

Another scientist, Benjamin Shappee of the Carnegie Institution for Science in Pasadena (California), described the outbreak as “surreal”. “This kind of discovery is the reason I’m an astronomer. Nature is very smart and sometimes has more imagination than we do, “he wrote in an e-mail.

Scientists agree that the explosion was so powerful and emitted so much energy that he questioned all of the current theories about supernovae. Nothing is known in particular about the mechanism of the phenomenon or the source of such an unimaginable amount of energy.

Scientists suspect that there may be similarly powerful stars in the universe that might explode at any moment. More detailed observations are planned, using the orbital Hubble telescope. According to Donga, the ASASSN-15lh explosion “can revise our approach to supernova phenomena.”

The MacBook Air in 2015

Apple has had so far only 11 “and 13” McBook Air models, which are quite handy and functional, but still the company wants to sell a model that will fill the gap between the two models. In other words, the company plans to create a model with a 12-inch display.

Information is not yet certain, but such a scenario suggests rumors appearing on the web. According to them, the company is working on a new MacBook Air that will have a 12-inch display. DigiTimes says the serial production of the new hardware should start early next year. Other sources point out that the production has already started, but for now to a very limited extent, so anyway, on store shelves we will find it only in a few months.

The technical details of the new model are unknown, but unofficially it is said that Apple may apply a slightly different design here, so the hardware will be a bit thinner than the previous MacBook Air models. It has also been suggested that Intel Broadwell chips could be on board, but that is speculation.

VR technology will help overcome the fear of public appearances and height

Many people are unable to overcome even the most irrational fears. Samsung suggests that virtual reality can help to taming some of them.

The Korean concern has just launched a campaign called #BeFearless (fearless or fearless) and the first part of it is to help people fight public fears.

The four-week campaign is aimed at volunteers who want to get rid of the fear of speech, so this is a special virtual program that teaches you how to overcome such anxiety step by step. The program consists of several different scenarios with realistic sound, during which the participant must perform various tasks.

Scenarios take place at school, office and at business meetings and are designed to simulate a large audience, giving you the opportunity to experience what the participant waits for during a public appearance, surrounded by his or her home. In this way, the test participant should gain more self-confidence, which he can use in real life.

Another fear that could help to overcome virtual reality is fear of height.

5 absurd channels that have been successful

YouTube, a Google video platform, has made it possible for anyone to publish material and the chance to reach the global audience. But the greatest revolution was the opportunity to make money on such creativity. Ba, we already know more than one star for which no longer a label agent, but the internet has become a gateway to international fame.

What to do to earn? Of course, there is no single answer, although it is certainly important to have an idea (preferably one that no one has yet fallen into), a realization (no work done) and a bit of luck that will make one of the material on your channel It will get even for a moment, loudly. This is the number of subscribers, reach, and number of views in a month become capitals that are converted to real cash.

Below are some channels that have done so well.

What’s Inside? (2.7 million subscriptions)

What is the interior of football, lava lamp or rattlesnake tail? The fact that the curiosity of the world is a natural feature has already convinced many parents, when their comfort dismantled a device to find out what is inside. It seems that with age, this feature in most of us is slightly dulled … although certainly not in the case of the author of this channel, who usually in the company of the son trying to answer the question “what is inside” in the simplest possible way.

Slow Mo Guys (8 million subscriptions)

Slow motion movies are always cool to watch, but no one waits for new episodes with bated breath. Slow Mo Guys, however, have a serious asset to strengthen their position: they do not have to be afraid of the followers, especially, which guarantees the high price of the camera necessary to make such shots.

GizmoSlip (1.8 million subscriptions)

The resistance of expensive gadgets is something that we do not test ourselves … voluntarily. These guys, however, made a way to make money.

Expensive gadgets are certainly not one of the original ideas, so the success of GizmoSlip must be based on a solid business plan that will ensure that the money spent on the destroyed hardware will pay off.

So we will see smartphones dropped, melt, roasted, baked, freezing, and we will also see if the Nokia 3310 will be a blade of katana and see how many 4K TVs will pierce the bolt fired from the strongest crossbow in the world.

Carsandwater (800 thousand subscriptions)

Popular science channels, whose creators do a variety of experiments on YouTube, will find a few. That is why, at a random hit, we choose one whose owner likes to catapult various objects heated red metal ball.

Apple is thinking about wirelessly charging iPhones

One of Apple’s newest patents has appeared on the Web, suggesting a major change in the functionality of the iPhone. The sketch shows plans to create a wireless smartphone battery charging system.

Apple has very slowly introduced to the smartphone technology solutions that rivals have long offered. It was with front cameras, LTE modem, NFC chip and other components. The same applies to wireless battery charging systems that have been standard in many smartphones for several years. In the meantime, we still can not see them in Apple products.

This may change, however, as a sketch of one of Cupertino’s newest patents appears on the Web, showing a wireless charger.

It is not, however, a typical induction charger that Samsung offers. Instead of standard electromagnetic induction, the device uses radio waves and magnetic resonance. With this solution, the smartphone will not have to be on the charger, but lie next to it, but still will be charged.
