D supercomputer simulations that could help first responders prepare for how an asteroid might behave once it crosses through Earth’s atmosphere. As a part of the effort, the researchers ran large- scale simulations of a Chelyabinsk- like asteroid, revealing the dramatic fluid flow that takes place as the space rock melts and vaporizes on its journey toward the surface.

D supercomputer simulations that could help first responders prepare for how an asteroid might behave once it crosses through Earth’s atmosphere. The researchers with NASA’s Asteroid Threat Assessment Project used the Pleiades supercomputer at the Advanced Supercomputing facility to simulate potential asteroids of all different sizes.

This includes the Chelyabinsk space rock, which smashed windows and damaged buildings for 5. Russia. More than 1,2. Using NASA’s Cart. D and Lawrence Livermore National Lab’s ALE3. D modeling software, the researchers were able to create a multitude of impact scenarios. The dramatic simulation of a Chelyabinsk- like object shows its fiery transformation as it passes through the atmosphere.

When this happens, it melts, vaporizes, and finally, breaks apart. In the simulation, the object enters the atmosphere at 4. The high- pressure shock wave can be seen in red, orange, and yellow as it envelops the space rock.

When this happens, it melts, vaporizes, and finally, breaks apart. THE CHELYABINSK BLASTA meteor that blazed across southern Urals in February was the largest recorded meteor strike in more than a century. More than 1,6. 00 people were injured by the shock wave from the explosion, estimated to be as strong as 2. Hiroshima atomic bombs, as it landed near the city of Chelyabinsk.

However, only five of them turned out being real meteorites. Officials can be seen standing next to a 2. According to NASA, this causes the asteroid to ‘fracture and flatten like a pancake.’Fragments can be seen breaking off as well. But, while they may seem tiny, these fragments can be extremely destructive.‘The dispersed fragments (black) deposit most of the energy into the atmosphere within a relatively short distance, creating dangerous blast waves and thermal radiation on the ground,’ NASA explains.

The simulations come as a part of NASA’s ongoing efforts to prepare for an eventual asteroid strike. While the chance of a devastating impact like the 2.

IMPACT WILL HAPPEN 'SOONER OR LATER' EXPERT WARNS Researchers have discovered most of the asteroids that are about a kilometers in size, but are now on the hunt for those that are about 1. Although nobody knows when the next big impact will occur, scientists have found themselves under pressure to predict - and intercept - its arrival.'Sooner or later we will get..

It may not happen in our lifetime, he said, but 'the risk that Earth will get hit in a devastating event one day is very high.'For now, there is little we can do.

And yet, the first- ever mission to crash a probe into a small space rock to alter its trajectory suffered a major setback when European ministers declined in December to fund part of the project.'We are not ready to defend ourselves' against an Earth- bound object, said Densing. We have no active planetary defense measures.'Source: AFP Back in November, NASA teamed up with the Federal Emergency Management Agency for a series of exercises intended to simulate an asteroid emergency.

Facebook's New Watch Tab Does Not Look Like a You. Tube Killer at All.

On Wednesday, Facebook announced the rollout of Watch, what it is calling “a new platform for shows on Facebook.” It’s yet another foray by the social media company from the business of distributing other people’s content into producing and licensing its own, and differs from its existing video content in that it looks a lot like Netflix or You. Tube’s apps. Watch content will be “produced exclusively for it by partners,” who will take 5.

That content will be spread via channels like “Most Talked About” or “What’s Making People Laugh” categories that will be determined by how users interact with it. Watch will offer both a live comment feed where users can interact with the wider Facebook audience—something that already exists with Facebook Live streams—and the ability to “participate in a dedicated Facebook Group for the show.”Here’s a few shots of what it will look like on various formats, as shown in the press release. It definitely looks slick and polished, but even this initial glimpse hints that Watch is not the You. Tube or Snapchat killer Facebook wants it to be. Facebook’s launch programming for the new video section is, uh, not exactly the A- list talent one might think a company worth hundreds of billions of dollars could secure.

It includes Nas Daily, a show from a guy who quit his job to make one- minute travel videos “together with his fans from around the world” (a preview clip is titled “We Bought 1. Burgers”); a live show where motivational speaker Gabby Bernstein will interact with Facebook users; a cooking show where children will attempt to make a recipe; and in probably Facebook’s biggest grab, one live game of Major League Baseball a week. Another show mentioned in the launch is Returning the Favor, where host Mike Rowe “finds people doing something extraordinary for their community, tells the world about it, and in turn does something extraordinary for them.” Yet another focuses on “the passion and community of big- time high school football in Texas.”There’s a few more interesting options, like a NASA science show, and a live Nat Geo Wild safari program. But none of this seems particularly edgy or hard- hitting.

It’s the definition of safe. This is the kind of generic filler that forms so much of You. Tube’s bread and butter—but if that’s all they have lined up, what could possibly lure people from You. Tube itself, which has long been pumping out much more interesting content tailored to virtually every niche interest and community?

Facebook’s content strategy is almost certainly to prove functionality and its ability to drive users to the service, and then try to lure other content producers to the service. But like a number of Facebook products before it, it’s unclear why publishers would want to use the platform. For example, Facebook Live already allows publishers to stream content like protests or post- Game of Thrones commentary live to their pages. They can also push regular video content wherever they want without an exclusive deal, whether it’s Facebook, Twitter or You.

Tube, and all three of these channels can be embedded elsewhere. Another goal could be to compete with Snapchat, which lots of publishers have started using to push short- form video content. But it’s not clear how Watch will get those users to return by replicating some of Snapchat’s functionality, especially since the latter company’s video content tends to be in reality or unscripted formats which seem nicely in tune with its overall aesthetic.

This looks a lot like Facebook’s attempt to push publishers into the same kind of walled garden they built with Instant Articles. Large sections of the media were spooked it was a prelude to Facebook choking off traffic to other websites—why would Facebook let you link out when they can force you to live in the garden, right?—but the concept has stalled somewhat, as Instant wasn’t driving enough additional traffic to offset its lower advertising revenue. Facebook has a tendency to build platforms it just loses interest in. Instant is still around, but in a diminished role as Facebook tweaked its algorithm to drive users to friends’ posts, video content and most recently another story format to compete with Snapchat. In the past few days, it’s killed off its standalone Facebook Groups app and Lifestage, a “high schoolers only” Snapchat knockoff that ended up ranked #1,3. App Store’s social media category.

It’s certainly possible Watch will help Facebook swallow more and more of the internet into its ever- expanding gullet. But supplying a nice- looking video platform does not automatically create demand, and Facebook has repeatedly stumbled to create a business model that will keep both users and publishers inside of it instead of clicking out. We’ll see. No word on whether Donald Trump’s “real news” program will get a slot, but we doubt it.[Facebook]* Correction: Wednesday, not Tuesday.
