Stargazing is becoming much easier during this time of year because the nights are now much longer than days. Secondly, with the end of the summer light, the last weekend is dark enough for stellar observation for up to 6 hours!
Nevertheless, the best coloring of this week is early in the morning two to three hours before the sunrise. Who walks early and sets the alarm for 3 or 4 in the morning? You will want this great performance this week in the early morning sky, that is, if the clouds do not photograph the sky bomb. Fix a large cup of coffee, a bundle, grab a lawn and blankets, and prepare for pursuit. The performance is even better in darker rural areas, but even if you have to deal with city lights, it's worthwhile to insist.
When you first extinguish, just sit in the lawn for lawn or lean on the car and let your eyes use in the dark. You can not help but blow up a great star show that happens in the early morning of the southern sky. Fantastic winter constellations flood that part of the sky. "Orion and his gang" are gathering here. Orion Hunter and its surrounding group of constellations – Taurus Bull, Gemini Twins and others – gradually shift from south to the southwestern sky as you approach the morning darkness. I never get tired of seeing those beautiful heavenly signs. Although not quite winter, Orion and its sighthold are considered to be winter constellations, since in January, when Earth continues its orbit around the sun, these bright shiners are seen in the early evening sky, so consider them as a preview of the big evening stargazing.
To get to know this constellation, transfer a good federal star map of the star. On skymaponline.net you can find a good one and get up tomorrow morning. Make sure that you use the red filter lamp to view the map so as not to destroy the night vision. Of course, there are many many stellar applications for smartphones available. My favorite is "Sky Guide." In this application, your phone's display may turn red to keep your night view.
While in the early hours of the morning you are courteously enjoying all the bright stars, you will also see some stars shooting through the sky dome. They are not actually stars, but meteors that break into our atmosphere. Later this week and especially this weekend, you will have to see more meteors than usual. This is because the annual meteor shower Leonidov peak. Leonids are not the best meteor shower in the year, but I would put them on the top sheet. This year attracts them that there is no moonlight in the early morning hours, making it a much darker background to capture those "falling stars".
Annual meteor showers, such as the Leonids, appear when the Earth floats in its orbit around the sun in the remnants left behind by the comet. Comets are more or less "dirty snowballs" of rocks and ice that orbit the sun in very elliptical oblong orbits. When taken by their orbit near the sun, they partially melt so that debris paths consist of small particles, from the size of powdered grains to small pebbles, the size of small marbles.
The comet, powered by the Leonid meteor shower, is called Temple Tuttle, which in 1998 this part of the solar system came and will not return until 2031. The earth in its solar orbit is followed by Temple Tuttle at 66,000 km / h, at the same time as well as these individual pieces of elbow or spheres that are in their orbit go thousands of kilometers per hour. This means that the remains in our atmosphere can be shed at speeds above 150,000 km / h!
With this type of speed, the individual particles quickly burn out due to huge air friction, but the light we see is not due to combustion. This is impossible to see because these fine particles heat up from 50 to 150 kilometers high. The tape we see is a glowing column of air chemically aroused by the particle that flows through it. Sometimes these lines appear to be of a different color, indicating the types of atmospheric gas that is temporarily aroused.
Meteor showers are best seen after midnight because this is when you are on the side of a rotating Earth that is loosening in comet rubbish. It's like riding a crossroads in a warm summer night. On the windshield on your windshield, you break more bugs than on the last window. After midnight, we face the "windshield" of the traveling Earth.
The Leonid meteor shower is not named after Soviet President Leonid Brezhnev. They are called Leonids because it appears that meteors originate from the sky, where the constellation Leo Lion is ready. After midnight Leo hangs in the eastern sky and looks like a back issue. This does not mean that we should limit hunting to meteors only to that area of heaven. If you do, you will miss a lot, as meteors can appear anywhere in the sky.
The best way to watch Leonids or other meteor shower is to lie on a lawn bed with blankets, night after midnight, preferably 2 or 3 in the morning, switch your eyes through the night sky and see how many meteors you see in a given hour. It's a fun group or family activity.
This weekend early in the evening, the new crescent light will be explained at the bright planet Venus in the low southwestern sky. Later this week, the first quarter of the moon will be really near the planet Mars in the evening of the southern sky. On Thursday, the moon will be on the lower right side of Mars, and on Mars, Mars will be parked in the upper left corner of the red planet.
