to observe the August stargazing – Perseid meteor shower – in 2013 developed an excellent condition. “Times” tells readers how, where and why you need to watch for “falling stars”, each of which is a model of the flight Chelyabinsk meteorite in the Earth’s atmosphere.
According to the forecast of the World Meteor Organization (IMO), a maximum of the Perseids meteor shower in 2013 will have on the night of 12 to August 13: if the number of observed “shooting stars” per hour could reach a hundred. On the weekend it will be somewhat less than the amount, but also decent: on Friday the observers recorded more than 25 meteors per hour. Moon this year will not interfere: being almost in the first quarter, it will have to go beyond the horizon in the early evening.
Starfall for the weekend
expected in the coming weekend August meteor shower – a maximum of the Perseids meteor shower. The Department of Science “Gazety.Ru” tells the story of a … ?
And forecast, at least for Moscow and Moscow Region , looks optimistic: it is expected that the next three days will be cloudy.
In order to observe the phenomenon of the meteor is not required large telescope, or even binoculars. You just have to come in from a remote location illumination of large cities.
Under these conditions, and if the weather forecasters do not make mistakes, and the clouds will not, can be guaranteed to see a shooting star in a few minutes.
«In Moscow, a very strong flare, and those who want to watch the meteors should pull in at least 50 km from the capital – said the head of research projects observatory” Ka-Dar “Stanislav Short . – From the medium-sized cities need to move off of at least 20 km ».
Residents of Moscow and the region can visit the massive free observation organized by the Pushchino Radio Astronomy Observatory, Astro Space Center of the Physics Institute of the Academy of Sciences (ASC FIAO PRAM).
«We are on the edge of Pushchino and obscured by trees on it, so we have a little flare: one can see the Milky Way and the stars of the fifth magnitude.
«A year ago, we went back to space science»
Exactly one year ago on Earth launched the first in many years, the domestic spacecraft – “Spektr-R”. “Times” tells the story of … ?
Of course, it could be better, but then it would be in the middle of a field of pure – said “the Newspaper” senior researcher PRAO ASC LPI Vladimir Samodurov. – These activities are carried out at us since 2009. They come crowds. Lots of kids have a very curious that literally terrorized issues ».
This year the event will take place on Saturday from 15.00 to 24.00. In the afternoon, when the light and shooting is not yet visible, visitors can visit the tour of radio astronomy observatory telescopes and learn about how to operate radio astronomers and what they are learning, as well as the latest news of the project «Radioastron» – the Russian space radio telescope.
Do not confuse the term “meteor” and “meteorite”, and especially “asteroid».
Asteroids – are small (a few hundred meters to several kilometers) of celestial bodies that orbit the sun, and sometimes, as, for example, Friday morning , are in the vicinity of the Earth. Meteor same can not be touched: it is the phenomenon of “shooting star” caused by the fact that a certain body at high speed (up to 50 km / s) enters the Earth’s atmosphere due to the resistance and the gaseous envelope of the planet begins to ionize and heat up this shell, causing the glow. If the body is large, then it becomes quite a bright light, and the body itself, considerably decreased in size and melted reaches the Earth’s surface. Such a body is called a meteorite. In the fall of a meteorite Chelyabinsk in February of this year, the brightness of its radiation in the atmosphere at some point exceeded the sun.
Strictly speaking, each meteor that readers will notice the “Gazety.Ru” and observers around the world in the next few days, is a model of flight Chelyabinsk meteorite in the atmosphere. The only difference is that a meteor caused by fine particle or even a speck of dust, and the atmosphere of the Chelyabinsk became the body size of a few meters.
Do not forget to make a wish!
11 and 12 August, astronomers expect the peak of the Perseid meteor shower activity – one of the brightest and richest annual flows. Residents … ?
The converse is also true: we can say that the Chelyabinsk meteorite caused a phenomenon very bright meteor. This phenomenon is often called the word «car» .
Fine particles that burn up in the atmosphere, causing a meteor phenomenon, usually once lay at the core of one of the periodic comets. They revolve around the sun, lying along the orbit of a comet its progenitor, forming a thick swarm of real space in the tens or hundreds of thousands of kilometers. Perseid meteor shower, the maximum activity which falls on August 10-12, owes its origins to the comet Swift-Tuttle, discovered in the middle of the XIX century and returning to the Sun every 130 years. It got its name because if the mind will continue to monitor its meteors backwards, they all come together at about the same point in the sky – not far from the star Gamma constellation Perseus. Such a point in everyone’s meteor shower, it is called a radiant. In fact, it is only the effect of perspective – just as if you drive at night in the snow on the machine, then it would seem that all the snowflakes are flying from one point.
Actually meteor particles enter the upper atmosphere by almost parallel paths.
In observations IMO recommends looking slightly to the side of the direction of the radiant taking azimuth 60 degrees left or right.
