Back in March, scientists detected 10 powerful bursts of radio signals coming from the same location in space. And now researchers have just picked up six more of the signals seemingly emanating from the same region, far beyond our Milky Way.

These fast radio bursts (FRB) are some of the most elusive and explosive signals ever detected from space - they only last milliseconds, but in that short period of time, they generate as much energy as the Sun in an entire day. But despite how powerful they are, scientists still aren't sure what causes them.

Until the detection of the 10 repeating signals back in March, it was thought that the bursts were only ever one-off events, coming from random locations around space. And without a discernible pattern to them, researchers were left stumped as to what could be causing them.

The reason we're so in the dark about FRB isn't that they're that uncommon - researchers have estimated that there are around 2,000 of these FRBs firing across the Universe every single day - but that they're so incredibly short-lived that we struggle to detect them.

It was only in 2007 that we discovered FRB, and it wasn't until earlier this year that researchers were quick enough to see one happening in real time. Usually we have to study the events long after the fact.

But now that we've detected 16 of the signals all coming from the same place, scientists might finally begin to narrow down options for what could be causing the powerful bursts.

The first 10 radio bursts detected coming from this one region were first identified in March this year, but they actually occurred in May and June 2015.

Not only were these the first FRB ever detected outside our galaxy - the rest all appeared to originate in the Milky Way - but they also created a repeating pattern of signals unlike anything we'd seen before.

Six of the bursts were recorded arriving at the Arecibo radio telescope in Puerto Rico within just 10 minutes of each other, and then four more spread out signals were detected over the next month, all coming from the same place.

When the team looked back over the data, they also saw a FRB from 2012 that appeared to come from the same location, too, making a total of 11 FRB from the one spot, and indicating that there was something out there beyond the Milky Way that was regularly producing the extremely short and intense signals.

Now a team of researchers from McGill University in Canada has found six more of the mysterious signals coming from the same spot, which has become known as FRB 121102, after the first FRB detected there.

"We report on radio and X-ray observations of the only known repeating fast radio burst source, FRB 121102," the team wrote in The Astrophysical Journal.

"We have detected six additional radio bursts from this source: five with the Green Bank Telescope at 2 GHz, and one at 1.4 GHz with the Arecibo Observatory, for a total of 17 bursts from this source."

The team can't pinpoint the exact location of FRB 121102, but based on the specific way their lower frequencies are slowed, they can tell they came from a long way away, far beyond the Milky Way. And that gives us some pretty important clues about what could be causing the events.

Interestingly, it also contradicts the evidence we have on FRB coming from within our own galaxy.

Currently, the leading hypothesis for the source of the Milky Way's FRB is the cataclysmic collision of two neutron stars, which forms a black hole. The idea is that as this collision happens, huge amounts of short-lived radio energy are blasted out into space.

But the repeating nature of these distant signals, all coming from the same place, suggest that can't be the case - at least for these particular FRB.

Instead, the 17 radio bursts detected from FRB 121102 indicate that something less dramatic is going on - the most likely hypothesis at the moment for these outer-galactic FRB is that they're coming from an exotic object such as a young neutron star, that's rotating with enough power to regularly emit the extremely bright pulses. 

The good news is that the two types of FRB don't necessarily contradict each other - a more likely prediction is that there's more than one type of FRB out there, both with different origins.

This is supported by the fact that the repeating FRB 121102 radio burst signals appear to be wider than the one-off events detected coming from within the galaxy.

But without more evidence to go on, researchers still can't say for sure what's going on.

"Whether FRB 121102 is a unique object in the currently known sample of FRBs, or all FRBs are capable of repeating, its characterisation is extremely important to understanding fast extragalactic radio transients," the team writes.

The race is now on to detect more of these FRB, either from within or outside our galaxy, and try to nail down once and for all where they're coming from. Because the strange events could also provide insight into the other mysteries happening within our Universe.

The rumor mill surrounding the Galaxy S8 is in full production mode at the moment, with anonymous sources from all corners of the web revealing potential features and design elements long before Samsung is ready to reveal the phone in earnest. The latest comes from Fone Arena, which reports that the S8 will follow the iPhone 7’s lead in the speaker department.

The iPhone 7 was the first iPhone to feature stereo speakers, and it’s an addition that has been roundly praised by reviewers and users alike. Now, Samsung will reportedly follow suit, adding stereo speakers to the S8, along with special branding to draw more attention to the feature.

One of the HTC One’s marquee features was its stereo speaker setup that the company branded BoomSound. The report suggests that Samsung has something similar in mind for the speakers on the new S8.

Curiously, the report also suggests that the S8 could draw upon Samsung’s recent $8 billion purchase of Harman to give its new stereo smartphone some added flair. However, this is something that was already shot down by Harman’s own CEO, Dinesh Paliwal, just a couple of weeks ago. At the time, Paliwal suggests that the timeline to integrate any Harman technology into the S8 was simply too short, and that Samsung’s smartphones would have to wait until 2018 before they could benefit from the acquisition.

“Since we are globally number one in audio technology, we plan to create new opportunities by applying the audio technologies into Samsung’s smartphones and home appliances. We may adopt Harman’s luxury audio technology into Galaxy S series possibly in 2018,” Paliwal said.

It’s not even 2017 yet, and it seems that Apple and Samsung will launch two of the most impressive smartphones of the coming year. Both the iPhone 8 and Galaxy S8 are going to feature brand new designs, as Apple and Samsung are working on all-glass devices that are supposed to support similar features. For the first time, both the new iPhone and Galaxy S models will come with OLED displays that incorporate fingerprint scanners and other sensors. Curved screens are reportedly in the works for both devices, and so are dual-lens rear cameras.

But what about the selfies cameras? A new report says the new Galaxy S model is going to have an even better front-facing camera with a feature that has never been seen before on an iPhone. 

Korean site ETNews reports that Samsung has decided to equip the Galaxy S8 with an auto-focus front-facing camera that will let users take even better selfies.

“People are starting to take more selfies and number of demands for cameras that take selfies with higher qualities is increasing,” an unnamed representative for the industry said. Samsung is therefore rumored to add autofocus to the camera to differentiate its flagship phone from competitors.

Samsung has figured out a way to add autofocus to the front camera without increasing the size of the camera module or the thickness of the phone. ETNewssays that the Galaxy S8 will use an “encoder” method that has coils at the side, rather than a Voice Coil Motor that’s used in rear cameras for autofocus. Samsung has not commented on the matter, saying that it “cannot discuss any information regarding new products that are not commercialized yet.”

It’s unclear at this time whether the FaceTime camera in the upcoming iPhone 8 will have autofocus or not. Current and past FaceTime camera versions do not have autofocus. The Galaxy S8 is expected to launch in early March next year, while the iPhone 8 will likely hit stores in mid-September.

It looks like Samsung is gearing for a comeback with the Galaxy Note 8 quick after the disaster that is the Galaxy Note 7.

Everyone lay witness to the huge crash that Samsung experienced with the Samsung Galaxy Note 7, which forced the company to do a complete recall of all units of the said model. Despite this huge failure on Samsung’s part, however, The Guardian reports that Samsung continues to lead in the global smartphone market in the third quarter of this year, still at 20 percent of the market share right before tight contender Apple.

But Samsung knows it has to shape up with the upcoming Galaxy S8, S8 Plus, and Note 8 to keep its lead in the race. With Apple’s not-so-popular iPhone 7, the playing field could still be quite even for the two smartphone giants.

The upcoming Galaxy S8, S8 Plus, and Note 8 units have sparked yet another speculation chain all over the internet because everyone knows its only a matter of time before Samsung releases an update to its smartphone and phablet lines. But before October ended, a Samsung representative spoke with CIO.

“Samsung has not officially communicated any information about a new Note lineup, so any reports referring to a new Note device are purely speculation and are not in reference to any communications from Samsung on a future Note.”

But everyone is convinced that Samsung is not yet ready to give up on the Note line. In fact, Samsung did confirm to Reuters in an official statement that customers who once owned a Galaxy Note 7 in South Korea will be able to get their hands on a Galaxy S8 or Note 8 update through an upgrade program when these models come out next year. This upgrade program will let the previous Galaxy Note 7 users to purchase Galaxy S8 or Note 8 next year for a half the price

As of date, the said upgrade program was only confirmed for South Korean owners and international patrons are hoping that Samsung will extend to them a similar upgrade program when the Galaxy S8 and Galaxy Note 8 hits the market.

“In addition to offering refunds or exchanges for a Galaxy S7 smartphone, Samsung has already offered financial incentives amounting to 100,000 won ($88.39) to affected customers in South Korea. Users in the upgrade program will need to pay only half the price of a Galaxy S7 device, rather than the full amount, before exchanging to the S8 or the Note 8,” Samsung said.

Surely, the Galaxy S8 and Galaxy Note 8 are already in development. But Tech Times confirms this news via Evan Blass, a known mobile reporter who has a knack for reporting unannounced smartphone news.

In a recent tweet, Blass confirmed that the upcoming Galaxy S8 models will ship as SM-G950 and SM-G955.

We are highly certain that SM-N950 is the model number for the upcoming Samsung Galaxy Note 8 since we know that the Note 7’s model number was SM-930, Galaxy Note 5 was SM-920, Galaxy Note 4 was SM-N910, and Galaxy Note 3 was SM-900.

A previous Inquisitr report cited Patrick Moorhead, chief analyst of Moor Insights & Strategy, who believes that the release of the Galaxy S8 and Galaxy Note 8 could be as early as January 2017.

“I think come January or March — January at CES or March at Mobile World Congress — they’ll come out with a Note 8. But it will be their high-end phone that not only goes after high-end consumers but enterprise as well.”

Surely, if Samsung has already come out with an upgrade program that involves the newer Galaxy S8 and Note 8, it’s only a matter of time before these new units get official release. With both the Note line having caught up with Samsung’s S line, Vine Report believes that the release of the Galaxy S8 and S8 Plus will be alongside the release of the Note 8.

The Samsung Galaxy Note 7 is officially dead — it exploded in popularity (teehee), but technical issues have forced Samsung to suspend the series’ annual refresh. That means that we won’t be getting any new smartphones from Samsung that come equipped with a stylus this year.

It’s a shame, because for some folks it’s the S-Pen that keeps them coming back to the Galaxy Note lineup, and it’s clear why — no one is matching Samsung in the digitized stylus game. The company even has roots in the #1 digitizer company running the show. The S-Pen’s years of refinement have resulted in an experience that increasingly blended the lines between screen and paper, and pen and, well, S-Pen.

Galaxy Note 5

If you’re one of those people and absolutely can’t go without an S-Pen or stylus these days, we’re here to help. Here are the best smartphones you can buy today that come equipped with a stylus.

Galaxy Note 5
Galaxy Note 7 Alternetives Best Android Phone with a Stylus

 

At first glance, people might still think it’s a Note 7.

Surprise! The best alternative to the Samsung Galaxy Note 7 is the very device it was replacing. TheSamsung Galaxy Note 5 doesn’t come with some of the same quirks we were to enjoy on the Galaxy Note 7:

  • Iris scanner.
  • Snapdragon 820
  • IP68 Water Resistance
  • microSD slot

That said, the device does share a fair bit of other things, like it’s slick build and good looks, fast performance, and great display and camera. Oh, and we can’t forget about the digitized stylus known as the S-Pen, of course. If you absolutely can’t live without a Note, then this is the phone to buy for now. Get our full opinion on this phone in our Galaxy Note 5 review.

Galaxy Note Edge

Galaxy_Note_Edge.jpg

For all of the good things the Samsung Galaxy Note 5 has, there are a couple that people deem unforgivable. The biggest complaint from that crowd was the lack of a removable battery and microSD card. Well, the Galaxy Note Edge — or the Galaxy Note 4 if you don’t dig the Edge display — has you covered in that regard.

This phone is a bit long in the tooth by now with it being a 2014 model, but it’s still receiving modern versions of Android and should be able to hold its own for almost any task you have for it.

LG Stylo 2 V

LG_Stylo_2_V.jpg

This Verizon-only phone takes after the long-running LG Stylo / Stylus line in its form and function. It features middling specs, albiet it at an appropriate price tag at just over $200. The phone includes a stylus, though it isn’t remarkable. The writing functionality itself is limited, as there’s no pressure sensitivity or proximity-based features that the Wacom-enabled Note series provides.

But, it is smart enough to alert you when you’re moving with your phone without the stylus inserted, and the phone can bring up a quick memo box when it detects you’ve taken it from its holster. Internals also aren’t too bad with a 1.8GHz Octa-Core Snapdragon chipset, 13MP rear camera, 5MP front camera, 5.7-inch 1080p display, and more.

LG Stylo / Stylus 2 PlusLG_Stylo__Stylus_2_Plus.jpg

These 2 phones are cut from the same cloth, and both are slightly weaker variants of the LG Stylo 2 V. With a 1.4GHz chipset instead of one clocked at 1.8GHz, it’s not a huge downfall. It’s stil Octa-Core in its architecture, and all the other specs fall in line with Verizon’s latest model. And there’s also the fact that you don’t need to be a Verizon customer to use these, and European models may come with DAB+ radio support for those in that region.

LG Stylus 2LG_Stylus_2.jpg

If your budget is stretched really thin, this is your option. The Stylus 2 sticks with the familiar 5.7-inch form factor of all the models above, only its screen resolution sticks at 720p and it’s sporting a weaker 1.2GHz quad-core chipset.

The best smartphone stylus

The_best_smartphone_stylus.jpg

For those who simply can’t or won’t accept any of the options discussed above, here’s one hail mary: get yourself a capacitive stylus. There are downsides to this route:

Capacitive stylus pens typically don’t work nearly as well as pens designed for specific phones. They’ll write, but not quite as accurately and without any pen-like qualities.
You’ll need a case with a slot to store it. Or you’ll have to put it in your pocket. Or latch it onto your phone using a string. None of these solutions are pretty.
There may not be appropriate software on your phone to take advantage of it, but many note taking apps should give you what you’re looking for.
Knowing all of that, if you still want or need a stylus for your phone of choice, we’re recommending MEKO’s 2-in-1 set of stylus pens. You get 2 pens in one box, and they support removable fiber tips (2 included) and a disc tip (4 included). Fiber tips are used more for general navigation and operation, while you’ll want the disc tip for smoother and more accurate hand-writing and drawing.

That’s not going to solve any dilemma that requires pressure sensitivity or anything else a proper stylus like the S-Pen can provide, but there you have it. It’s even affordable at a cool $15 for that package.

Otherwise, Here’s hoping a proper Samsung Galaxy Note sequel exists somewhere in Samsung’s future.

The telescope at China's Purple Mountain Observatory in Nanjing has captured images of an asteroid approaching Earth. The asteroid, coded as 2009ES by the Minor Planet Center (MPC), was observed Wednesday night. This is the first time that a telescope in China has captured images of the asteroid, one of 1,640 minor bodies listed by MPC that could have a close encounter with the Earth.

Scientists estimate that should an asteroid measuring 10,000 meters collide with Earth, the impact would equal the explosion capacity of 3 billion atomic bombs. Astronomers widely believe that such an asteroid hit the Earth 65 million years ago, wiping out the dinosaurs.

The observatory's 1.2-meter Schmit is the largest telescope of its kind in Asia.
The observatory was notified by MPC on Sept. 5 to observe the asteroid. It passed Earth within a range 18.8 times of the distance between the Earth and the Moon.

Zhao Haibin with the observatory said minor planets' trajectories could be changed by stellar attraction from planets such as Mars. Continuous observation is needed to keep track of any changes.

"With the help of our images, astronomers across the globe have a more accurate moving trajectory of the asteroid," he said. Previously, eight other telescopes around the world had captured images of the asteroid.

The U.S. Federal Aviation Administration is cautioning air passengers that they should not turn on or charge their Samsung Galaxy Note 7 smartphones while on board and they should not stow them in checked baggage, following reports that a few dozen of the phones' batteries have exploded or caught fire.

The extraordinary caution was published Thursday on the FAA's website. 

"In light of recent incidents and concerns raised by Samsung about its Galaxy Note 7 devices, the Federal Aviation Administration strongly advises passengers not to turn on or charge these devices on board aircraft and not to stow them in any checked baggage," the statement said.

Samsung's parent company announced last week it would exchange phones in 10 countries, including Canada, after disclosing 35 cases of Note 7s that had burst into flames or exploded because of defective batteries from one supplier.

Samsung Electronics Canada says there have been no confirmed incidents in this country, but it's offering a voluntary exchange program for its Canadian customers.

Owners of the phone in Canada can exchange a recalled device for a new one of the same model.

The company says customers can also exchange a recalled device for a Galaxy S7 or Galaxy S7 Edge through the carrier or the retailer that sold the device.

Samsung says Note 7 owners can initiate the exchange by visiting CanadaNote7exchange.expertinquiry.com.

A toll-free phone number is also available: 1-800-517-3507.

Samsung's exploding phone crisis is getting worse.

 

A 6-year-old boy was rushed to the hospital in Brooklyn, New York on Saturday after a Galaxy Note7 caught fire in his hands, according to a report in the New York Post

"The child was watching videos on the phone when the battery exploded," Linda Lewis, the boy's grandmother, told the newspaper. She later said he has since been released from the hospital.

 

This may be the first injury caused by the defective phones, though Samsung says it knows of at least 35 instances of the Note7 battery exploding or catching fire.

Samsung is working with the U.S. Consumer Product Safety Commission to officially recall the device, but the incident in Brooklyn suggests that may be too little, too late. If the Note7 is your only device, you're up the creek without a paddle: You could exchange the device with your carrier, but if you don't have time for the hassle, are you supposed to go about your business without a working phone? Good luck with that in 2016 — especially if you're traveling, as the Federal Aviation Administration has warned against using the phone on planes.

Besides, Samsung and carriers haven't provided clear information about what customers should do with their Note7 phones. Initially, carriers said to reach out to Samsung directly. Then, Samsung asked customers to circle back with their carriers. And no one seems to know when replacement Note7 phones might hit the market — at least based on conversations I've had with Verizon as a Note7 owner myself. (Womp womp.)

 

Your best bet right now is to go to your service provider — Verizon, AT&T, whatever — and exchange the phone for a different model entirely. The only problem there is that the Note7 was dubbed the best smartphone you can buy today before it got all explodey, so anything you sub in will be a downgrade.

Meanwhile, a little company called Apple is launching a shiny new line of iPhones on Friday. Good timing.
