Perseids, a Meteor Shower Famous For Its Fireballs, Is Peaking Tonight

There are few things more special than watching a shooting star streak across the sky on a warm summer evening.
Viewers across the United States will have a chance Sunday night into the pre-dawn hours on Monday, as well as Monday night into early Tuesday morning, when a dozen meteors per hour and possibly up to 50 or more at its peak are slated to dazzle the heavens after dark.

Meteor showers occur when Earth enters a spattering of space-borne debris. The debris usually stems from a larger object - namely a comet or asteroid - that passed by long ago.

The Perseids occur as Earth passes through the debris trail of the comet Swift-Tuttle.
The reason we see the meteor shower at the same time each year is because Earth moves through the same area of debris at this point in its annual orbit around the sun.
When a piece of debris strikes the outer atmosphere about 60 miles (100 kilometers) high, friction causes it to burn up. Most of the shooting stars you see actually come from pebbles the size of a grain of rice or smaller.
"But if you see a fireball, it's probably bigger," says Bill Cooke, who leads NASA's Meteoroid Environment Office. "Those ones are about a centimeter across."
Where to look
You're unlikely to catch more than a few sporadic shooting stars during twilight, before about 10 pm. After that, there's no specific place to look - just up!

Some people seek out the show's radiant, which marks the point from which all the shooting stars appear to originate. That would be the constellation Perseus, hanging low in the northern/northeastern sky.
There's no special benefit to looking there, however. In fact, many skywatchers look away from the radiant to see shooting stars that have the longest, most spectacular-looking tails.
The Perseids are the most popular meteor shower of the year, in large part because they occur during the Northern Hemisphere summer.
"They're convenient," Cooke says. "The Geminids produce more meteors, but they're in mid-December. With the Perseids, the nights are comfortable, and you can watch them without freezing your carcass off."
Where to watch the Perseids

Watching a meteor shower is a bit like real estate; it's all about location, location, location.
The Perseids will be visible across the United States and elsewhere, and the best viewing will be found away from light pollution. For example, if you live in Washington DC and are looking for the best show, try the Shenandoah National Park in Virginia, or farther east along the shores of the Rappahannock River.
Bring a blanket or towel to sit on, and some snacks and bug spray. (And maybe a flashlight to inspect for potential spider-related hazards before settling down.)
The Moon will act to dim the show
The Perseids will be limited this year, however, by moonlight, which will effectively block viewing of many of the fainter meteors.
However, the Perseids are known for their fireballs, or extremely bright meteors, which will still shine through the moonlight.
If you see one, you'll certainly know it! Sometimes fireballs are caused by the object that hits Earth's atmosphere being greater in size; other times it's a result of the meteor penetrating deeper into the atmosphere. Most of the time it's both.
The colors you see depend on the composition of the meteor. "Perseids show a strong sodium signal," Cooke says. "That's why they often appear yellow."
Although it's tough to determine their elemental composition, some meteors have been known to contain magnesium, iron, carbon and silicon. Colors can also come from ionization of the surrounding air.
The Perseid meteor shower has a peak that lasts a few days, so if you miss the peak Monday or Tuesday, don't fret. You'll still be able to catch some more shooting stars over the next few nights.
Showing up to work a bit drowsy is a small price to pay for such a stunning celestial spectacle. Weather permitting, it should be a decent, albeit more-muted-than-average, show.

  1. Hello, I am Jennifer After being in relationship with Anderson for years, he broke up with me, I did everything possible to bring him back but all was in vain, I wanted him back so much because of the love I have for him, I begged him with everything, I made promises but he refused. I explained my problem to my friend and she suggested that I should rather contact a spell caster that could help me cast a spell to bring him back but I am the type that never believed in spell, I had no choice than to try it, I mailed the spell caster, and he told me there was no problem that everything will be okay before three days, that my ex will return to me before three days, he cast the spell and surprisingly in the second day, it was around 4pm. My ex called me, I was so surprised, I answered the call and all he said was that he was so sorry for everything that happened that he wanted me to return to him, that he loves me so much. I was so happy and went to him that was how we started living together happily again. Since then, I have made promise that anybody I know that have a relationship problem, I would be of help to such person by referring him or her to the only real and powerful spell caster who helped me with my own problem. email: you can email him if you need his assistance in your relationship or any other Case.
