Right now, the Earth is passing through fragments and dust trails created by the Comet Swift-Tuttle and this means the  Perseids Meteor Shower  has begun and will be getting stronger each day and it will peak from August 11-14. Lewis  Swift and Horace Parnell-Tuttle discovered the Swift-Tuttle Comet in July of 1862. The comet passed by Earth in 1992  and will not return again until 2126, however the dust left behind by this comet creates a dependable annual meteor  shower, the Perseids. The Perseids is named after constellation Perseus because meteors seem to spread out from  an area surrounding the constellation, this is called the radiant.

The Perseids Meteor Shower will peak in the morning of August 12, meteors can be seen anywhere in the sky. The  main thing to viewing any meteor shower is to find a safe, dark place away from man-made lights and lean back in a  relaxing position looking toward the darkest part of the sky. Sometimes the Moon can be a hindrance, but this year the  Moon will not be shedding much light, as during the peak it will be a waxing crescent Moon phase, so this means more  visible meteors.

It is predicted that The Perseids Meteor Shower is going to have some great activity this year, up to 100 meteors per  hour! It promises to be the best meteor shower this year. The meteors (shooting stars) are produced when debris left  behind by a comet ranging from, as big as grains of sand to the size of a pebble, enter the Earth’s atmosphere with  speeds reaching, 70 kilometres per second, and burn high up in the atmosphere due to friction and vaporise which causes them to glow brightly. A lot of junk hits our atmosphere so a good way to find out if you’re looking at a sporadic meteor or one from Perseids is to find where it originates from, if its moving away from the radiant it probably belongs to Perseids, if it’s going towards the radiant it’s a sporadic one, it’s always a good idea NOT to look directly at the radiant, as most meteors are going away from it. If you’re unlucky and have cloudy skies, don’t’ worry, you can hear the meteors! Just take an old radio out and tune it to the lowest frequency and you can hear the meteor echoes which sound like this. You can find more about meteor echoes here.

Meteor showers are one of the most spectacular astronomical events and it’s really easy to catch them, all you have to do  is go out and look up, you don’t need anything but a dark clear patch of sky! And like most outdoor activities it’s best when you share the experience with your friends and family, the more eyes you have on the sky the more chances you have of catching the meteors streak across. I have a deep connection with meteor showers, when I saw my first one, it mesmerised me and inspired me to learn more about the sky above!

The Perseids Meteor Shower promises to be one of the best meteor showers of the year with lots of meteors streaking across the sky, you should definitely go out and see it!

The oil spill in the Gulf of Mexico has now been going on for 56 days. It has devastated the wildlife in the area. The damaged well has been leaking approximately 20,000 to 40,000 barrels of oil per day. On June 3rd BP lowered a new containment cap to catch some of the flow coming out from the damaged pipe. This cap, says BP is collecting 10,000 barrels of oil per day and transporting it to a tanker on the surface. No one knows the exact estimate but with 20,000 to 40,000 barrels of oil leaking per day -according to which estimate you follow-  this isn’t much.

As the oil surfaces on the ocean people are wondering how far it is going to travel.  Researchers National Center for Atmospheric Research (NCAR) have carried out a detailed simulation of the oil. This video animation of their simulation shows that the oil is going to spread out thousands of miles along the Atlantic coastline and the open ocean as soon as this summer.

Dr. Synte Peacock, an oceanographer at NCAR said in an interview in EarthSky.org on that the simulations used a dye, and not oil. A dye would travel to the Atlantic Ocean, but oil would behave differently.

Her team thinks that it’s very likely that the oil will get into the Atlantic

If it does, she said, people shouldn’t expect oil to coat Atlantic beaches and wildlife. That’s because, over the months it would take to travel there – if it does travel there – some oil will evaporate, be eaten by microbes, and become diluted in sea water.

Dr. Peacock added that in all the possible scenarios and simulations that were tested, oil from the oil spill traveled outside of the Gulf within 6 months. But she added that it’s still unclear if or how the oil will affect beaches on the Atlantic Coast. That eventual outcome is partially dependent on local weather around the time the oil reaches a beach.

While the world has turned their attention to the FIFA World Cup, images like this are becoming more common throughout the Gulf of Mexico and they might appear in the Atlantic.
