The Kuiper Belt is mainly made up of asteroids The heliopause is the point where solar wind meets interstellar space The Oort Cloud (left) is much larger than the inner solar system (right) or the Kuiper Belt (center) The location of the solar system's outer boundary is a point of contention among astronomers which "all have merit." But which one is best The solar system is an enormous place Our cosmic neighborhood includes eight planets several hundred moons and millions of asteroids and comets all spinning around the sun — and in many cases each other —at speeds of thousands of miles per hour But where does it end? Well, the answer may depend on whom you ask and how they define the solar system The arguments for each boundary "all have merit," which makes choosing between them complicated, Dan Reisenfeld a researcher at Los Alamos National Laboratory in New Mexico But there is one that most astronomers most commonly agree upon Related: Have all 8 planets ever aligned?  (One astronomical unit is equal to the distance between Earth and the sun.)  Get the world’s most fascinating discoveries delivered straight to your inbox This region is filled with asteroids and dwarf planets, such as Pluto that have been ejected from the inner solar system by one-sided gravitational tugs-of-war with the planets Some astronomers argue that the Kuiper Belt should be considered the edge of the solar system because it loosely represents the edge of where the sun's protoplanetary disk — the swirling ring of gas and dust that later became the planets moons and asteroids — would have been "If one narrowly defines the solar system as just the sun and its planetary bodies then the edge of the Kuiper Belt can be considered to be the edge of the solar system," Reisenfeld said.  But this definition of the solar system is considered to be far too simple by some astronomers, such as Caltech's Mike Brown.  The uncertainty around this region's own outer edge therefore makes it an unreliable boundary for the solar system as a whole The heliopause is the outer edge of the sun's magnetic influence, known as the heliosphere. At this point, the stream of charged particles emitted by the sun, known as the solar wind, becomes too weak to repel the oncoming stream of radiation from stars and other cosmic entities in the Milky Way.  Two spacecraft have traveled beyond the heliopause: Voyager 1 As the Voyager probes crossed the heliopause they quickly detected changes in the types and levels of magnetism and radiation hitting them signifying that they had crossed some kind of border which creates a bow shock — a rounded shock wave that deflects incoming radiation around the rest of the solar system The bow shock is located around 120 AU from the sun and creates a long tail that stretches at least 350 AU from the sun in the opposite direction Using the heliopause to delineate the solar system therefore leaves us with a lopsided neighborhood which goes against some researchers perceptions of planetary systems The Oort Cloud is the furthest and most expansive potential solar system boundary, extending up to around 100,000 AU from the sun, according to NASA.  "People who define the solar system as everything that is gravitationally bound to the Sun consider the edge of the Oort cloud to be the edge of the solar system," Reisenfeld said this is the clear choice for a solar system boundary because in theory a planetary system consists of all objects orbiting a star "I don't understand how anyone considers anything other than the Oort Cloud to be the edge of the solar system," Sean Raymond an astronomer at the Bordeaux Astrophysics Laboratory in France It is literally the edge of where something can orbit the Sun." other researchers believe that because the Oort Cloud is located in interstellar space it lies beyond the solar system even if it is bound to our home star.  There is also a large amount of uncertainty about where the Oort Cloud actually ends which some would argue makes it just as unreliable a border as the Kuiper Belt Out of the three possible boundaries, the heliopause is the one that is most often used by researchers, and by NASA This is because it is the easiest to pin down and because the magnetic properties on either side of it are significantly different "I would argue for the heliopause to be the boundary because it really is a boundary," Reisenfeld said —How many times has Earth orbited the sun?How many times has the sun traveled around the Milky Way?What's the maximum number of planets that could orbit the sun? But that doesn't mean that everything beyond the heliopause should be considered an interstellar object, such as the enormous space rock 'Oumuamua "The Oort Cloud was originally part of the same stuff that the planets were formed from so it is composed of solar system material But while some researchers are happy to pick a side in this argument others see no reason why the solar system cannot have multiple boundaries "I would say that there is no actual debate," Brown said "There are just different ways to define it depending on what is important for the question you are trying to answer."

Plaintiffs claim firm knowingly sold phones with microphone issues which prevented calls and voice assistant functionality Google is facing a class-action lawsuit over defects to its Pixel smartphones The plaintiffs allege that Google knowingly sold defective Pixel and Pixel XL smartphones which suffered from problems with the microphones that prevented them from being used for calling or voice assistant functionality “It promoted the Pixel phones as premium products and priced them from $649 to $869. Yet, immediately after launching the phones, customers complained directly to Google of ‘severe microphone issues’,” the two plaintiffs, Patricia Weeks from Florida and Waleed Anbar from California, said in the suit “Despite receiving hundreds of complaints shortly after launch – and admitting the phones have a ‘faulty microphone’ – Google continues to sell the Pixel phones without telling purchasers about the microphone defect.” Google’s support agents acknowledged the defects with the microphone, stating that the issues affected less than 1% of the units sold at the time and that, according to the firm’s vice president of product management Brian Rakowski a “hairline crack in the solder connection on the audio codec” was to blame Google urged those with affected Pixel smartphones to claim under warranty or to contact a service provider if out of warranty including Dixons Carphone Warehouse in the UK and uBreakiFix in the US “Instead of fixing the defective Pixel phones or replacing the devices with non-defective phones Google has replaced defective phones with other defective phones resulting in many consumers repeatedly experiencing the microphone defect,” the plaintiffs claim Google declined to comment on the lawsuit. years after adding a frowning face for Windows 8
