[ Perseid Meteor Shower 2017 : When, Where & How to See It]. But a noticeable upswing in Perseid activity has taken place during the last few nights, leading up to the meteors ' impending peak .

August 11, 2017 . Look up tonight and you’ll see streaks of light headed your way. The annual Perseid meteor shower has arrived, and if the skies are clear and light pollution low, you are in for quite a treat: This is easily the best meteor shower of the year.

Look up Friday and Saturday nights (Aug. 11 and 12) for this year's Perseid meteor shower peak.

For Northern Hemisphere observers, August is usually regarded as "meteor month," with one of the best displays of the year reaching its peak near midmonth. That display is, of course, the annual Perseid meteor shower, which is beloved by meteor enthusiasts and summer campers alike. But skywatchers beware: You will face a major obstacle in your attempt to observe this year's Perseid performance — namely, the moon. (Live in a big city? Find out how to see the Perseids from urban areas here from our sister site Active Junky.)

Perseid meteor shower coming soon to a sky near you

  Perseid meteor shower coming soon to a sky near you The best summertime meteor shower — the Perseids — will be coming to a sky near you next week, weather permitting. Despite wild media reports about it being the brightest meteor shower in human history, NASA said "no such thing is going to happen." The best summertime meteor shower — the Perseids — will be coming to a sky near you next week, weather permitting.

As (bad) luck would have it, this year, the moon turned full on Aug. 7, and it will be at a rather bright waning gibbous phase several nights later, seriously hampering observation of the peak of the Perseids, predicted to occur on the night of Aug. 11-12. (Aug. 12-13 will also have high rates, as the absolute peak is during the day Aug. 12, but will also be obscured by the moon.) [Perseid Meteor Shower 2017: When, Where & How to See It]

Moonrise on Aug. 11 comes at around 10:20 p.m. local time, while on Aug. 12, it's at around 10:50 p.m. The moon will be hovering below and to the left of the Great Square of Pegasus these nights and not all that far from the constellation Perseus, from where the meteors will appear to emanate (hence the name "Perseid"). Perseus does not begin to climb high up into the northeast sky until around midnight; by dawn, it's nearly overhead. But bright moonlight will flood the sky through most of those two key nights and will certainly play havoc with any serious attempts to observe these meteors.

So, unfortunately, the moon intervenes to spoil the Perseid's best, even if your part of the country is blessed with clear skies.

You do have options to watch the 2017 Perseids online. On Saturday, the online Slooh community observatory will host a free webcast of the Perseids here, beginning at 8 p.m. EDT (0000 GMT). The webcast will also appear on Space.com, courtesy of Slooh.

The Virtual Telescope Project based in Italy will host a live webcast Saturday at 4:50 p.m. EDT (2050 GMT). You can watch that Perseids webcast live here at start time.

The worst possible circumstance

The Perseids are already around, having been active, although weak and scattered, since around July 17. But a noticeable upswing in Perseid activity has taken place during the last few nights, leading up to the meteors' impending peak. They are typically fast and bright, and they occasionally leave persistent trains. Every once in a while, a Perseid fireball will blaze forth, bright enough to be quite spectacular and more than capable of attracting attention even in bright moonlight.

Samsung's rugged Galaxy S8 Active launches this week

  Samsung's rugged Galaxy S8 Active launches this week Samsung is officially releasing the Galaxy S8 Active on Friday, August 11. The new handset's specs match those that were leaked around two weeks ago. Internally, it carries all the high-end hardware from the standard Galaxy S8, including a Snapdragon 835 CPU, 4GB of RAM, and 64GB of storage. It also packs a 12-megapixel rear camera, and an 8-megapixel front-facing camera. The Active's main perk is its battery, which at 4,000mAh, is larger than the 3,000mAh and 3,500mAh batteries found inside the S8 and S8 plus, respectively.

Even more unfortunate than its brightness, the moon is full on Aug. 7, so it will always be above the horizon during the predawn morning hours (when Perseid viewing is at its best) in the few days before the peak. So moonlight will even spoil the gradual increase in the shower's meteor rates. The moon arrives at last quarter on Aug. 14, and thereafter, its light becomes much less objectionable. But by that time the peak of the display will have long since passed, leaving only a few lingering Perseid stragglers in its wake.

Comet crumbs

We know today that these meteors are the leftover debris shed by Comet Swift-Tuttle along its orbit. Discovered back in 1862, this comet takes approximately 130 years to circle the sun. And in much the same way that the Tempel-Tuttle comet leaves a trail of debris along its orbit to produce the spectacular Leonid meteors of November, Swift-Tuttle produces a debris trail along its orbit, causing the Perseids.

Indeed, every year during mid-August, when the Earth passes close to the orbit of Swift-Tuttle, the material left behind by the comet from its previous visits rams into Earth's atmosphere at approximately 37 miles per second (60 km/s) to create bright streaks of light in the midsummer night skies.

It also periodically provides free streams of celestial events like meteor showers, planets in opposition, and the occasional super beaver moon.

Aug 11, 2017 . Does the Perseid Meteor Shower ring a bell? Because of that, more faint meteors will not be able to be seen. Usually we can see up to 100 meteors per hour (or more) if there’s no bright moon, but with the brightness that number will be lower.

August 11, 2017 . The Perseid meteor shower is peaking this weekend , but something big is poised to interrupt your view: the moon. The moon will be about 80 percent full this weekend , the time to see the shower , so its brightness will obscure the sight of meteors .

Wait 'til 2018

Most years, in the absence of bright moonlight, a single observer watching from a clear and very dark location might see up to 90 meteors per hour on the peak night. This year, however, observers will see closer to 40-50.

But in 2018, the peak night will coincide with a new moon, making for a much different story. The skies will indeed be dark and meteors likely plentiful. As they used to say in Brooklyn, when the Dodgers played at old Ebbets Field, "Just wait 'til next year!"

A consolation shower

After the Perseids have gone, there is one last summer meteor shower left: the Kappa Cygnids (followed by the Orionids in the last half of October). The viewing period for this minor shower are rather short — Aug. 19-22 — with the peak on the 21st. Though the maximum rate is only four per hour, this stream does provide an occasional flaring fireball, and a careful observer may be nicely rewarded for the time spent. Sometimes, just a single spectacular object can make an entire night of watching worthwhile.

The viewing circumstances for the 2017 Kappa Cygnids are the best possible, since their peak this year coincides with a new moon — the same new moon that will eclipse the sun on that very same day. The constellation Cygnus, from which these meteors appear to radiate, is also popularly known as the Northern Cross. This cross will lie directly overhead at around midnight and will stand upright on the northwest horizon when dawn is breaking about 5 hours later.

It has as much kick as 17 Teslas discharging their batteries in a second.Using this technology researchers have already investigated the effects of meteor impacts on minerals within the Earth's crust, but the increased range and power of the laser means scientists can now begin exploring higher pressure material much further away. Shaughnessy Brennan Brown, a doctoral student in mechanical engineering, said the upgrade enables researchers "to generate exciting, previously-unexplored regimes of exotic matter -- such as those found on Mars, our next planetary stepping stone -- with crucial reliability and repeatability".
