Don’t worry, it’s not a gross mauling video, but Brad Josephs’ “A Grizzly Ate My GoPro!!!” video is generating some viral buzz today, and with good reason.

The explosion was caused by a meteorite, 0.3 to 0.4 meters wide, weighing in at about 40 kilograms. When it hit the moon, it was travelling at 56,000 miles per hour. According to NASA, it exploded with the force of 5 tons of TNT.

“On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium,” says Bill Cooke of NASA’s Meteoroid Environment Office. “It exploded in a flash nearly 10 times as bright as anything we’ve ever seen before.”

The impact was so bright, in fact, that anyone looking would have seen it without the help of a telescope.

“It jumped right out at me, it was so bright,” says Marshall Space Flight Center analyst Ron Suggs, who was the first to see the impact.

This type of lunar strike is common, but NASA has yet to see one this large in the nearly 8 years its been monitoring the moon for such impacts. Here’s why:

Unlike Earth, which has an atmosphere to protect it, the Moon is airless and exposed. “Lunar meteors” crash into the ground with fair frequency. Since the monitoring program began in 2005, NASA’s lunar impact team has detected more than 300 strikes, most orders of magnitude fainter than the March 17th event. Statistically speaking, more than half of all lunar meteors come from known meteoroid streams such as the Perseids and Leonids. The rest are sporadic meteors–random bits of comet and asteroid debris of unknown parentage.

Oh, by the way, the “explosion” is special thanks to the lack of oxygen in the Moon’s atmosphere.

“The Moon has no oxygen atmosphere, so how can something explode? Lunar meteors don’t require oxygen or combustion to make themselves visible. They hit the ground with so much kinetic energy that even a pebble can make a crater several feet wide. The flash of light comes not from combustion but rather from the thermal glow of molten rock and hot vapors at the impact site,” says NASA.

Google did announce a new Google Wallet API designed to help fight that shopping cart abandonment problem. More on that here.

This new design is called the YouTube One Channel, and YouTube has had it in beta for some time now. In that time, over 100 million channels have opted-in to the new look. But for all of you holdouts, your days with the old channel format are numbered. YouTube has just announced that all channels with be automatically and permanently moved to the new One Channel design by June 5th.

“Channels that have already made the switch are experiencing several benefits. Their branding shines through in more places because Channel Art is visible on iOS apps, Android apps and TV. For the channels that have opted in, we’ve seen 20% more page views on their channels because clicks from the YouTube guide go directly to their channel pages instead of to their activity feeds,” says YouTube

Here’s what the new channels look like:

Compare that to the old channels, which will no longer exist come June 5th:

Of course, if you’re a channel owner and you’re just now hearing about this – you can choose to opt-in early here.

And speaking of YouTube and channels, the company just expanded live streaming to any and all channels with 1000+ subscribers.

Eventually, though we don’t see it in the video, the driver reportedly let the deer out of the bus through the door, and it went back out into the wild. The incident reportedly happened in Johnstown, Pennsylvania.

Hot on the trail and catching up to the speeder, James hit a roadblock. Inncent lives were at stake. Of course, officers are sworn to protect and serve – even if those that need protection are on the featherier side of things.

The violator got away. Damnit, foiled by ducks again.

In this episode, TV’s Ron Swanson reads tweets from such starlets as Katy Perry, Miranda Cosgrove, and Jennette McCurdy.

If you’re interested, there’s a lot more where that came from.

At the end, CEO Larry Page made a surprise appearance, and engaged in a Q&A session with audience members.

The CW revival of the series, which started in the late 90′s and ran for 8 seasons on ABC, brings back Ryan Stiles, Wayne Brady, and Colin Mochrie – but has replaced the host. In the new version comedian Aisha Tyler is filling in for Drew Carey. The new series will feature a “special guest” for each episode, and will consist of ten 30-minute shows.

Impressions? Well, Colin and Ryan look a bit older, but other than that the performers don’t seem to have lost a step – even when they’re being forced to use 90210 as source material. And Laura Hall is back!

It’s an interesting topic if you’ve got 45 minutes to spare.
