Skywatch: The longer the night, the better the view of the stars.



It is easier to see this point in the year because the night is much longer than it is now. Secondly, after the end of daylight saving time last weekend, it was dark enough for the star until 6 pm.
Despite all this, the best stars this week are two hours to three hours early morning sunrise. Who is going to sleep early and ring an alarm for three to four hours in the morning? You will want a great performance this week in the early morning skies. If clouds do not drop bombs in the sky. Take a large cup of coffee, tie the bunch, and hold the lawn chair and blanket ready to be in a dazzling state. Shows are better in the darker countryside, but even if you have to compete with the city's lights, it's worth taking a look.
Mike Lynch First, sit on the lawn chair or lean on the car and get your eyes to get used to the darkness. You can not help but be blown away by a great star show in the sky early in the morning. Fantastic winter constellations overwhelm part of the sky. This is where Orion and his gang meet. Orion Hunter and his surrounding constellations – Taurus, Gemini twins – move gradually from south to southwest, as they approach the morning twilight. I am not tired of seeing the character of the great sun. It is not quite winter, but Orion and his wife are considered winter constellations. While the earth is turning around the sun in January, these bright people can be seen this week because they can be seen in the early evening sky. A preview of a nice evening star to come.
To learn about this constellation, download a map of the good January evening star. You can find good things at skymaponline.net and you can leave sometime in the evening in January. You can use the red filter flashlight to view the map, so you do not have to worry about night vision. Of course, there are many great apps for smartphones that you can use. My favorite is the "Sky Guide." This app can turn your phone screen red in order to maintain night vision.
In the early morning you can see a star shooting across the dome of the celestial globe while feeling the loveliness of all bright stars. They actually draw the meteors into our atmosphere, not the stars. This weekend and especially this weekend, you will see more meteors than usual. It is because Leonid's meteor shower will peak every year. Leonids is not the best meteor shower of the year but will put it in the upper tier. The reason we make them attractive this year is that in the early morning hours there is no moonlight, so we can catch that "falling star" in a darker background.
A year-round meteor shower like the Leonids occurs when the Earth's orbit's Earth flows into debris left behind by a comet. A comet is a "dirty snowball" of rock and ice that orbits the sun in a highly elliptical long orbit. When their orbit is close to the sun, they melt partially, leaving a trail of debris consisting of small particles ranging from the size of the dust particles to the small gravel for the size of the small beads.
The comet that supplies Leonid's meteor shower is called the Temple Tuttle and was last brought by this part of the solar system in 1998 and will not return until 2031. At the same time as Earth's orbit's 66,000 miles in Temple Tuttle, this individual comet shatter particle or bullet buzzles along orbits of thousands of miles per hour. This means that debris can hit our atmosphere at speeds of over 150,000 miles!
At such a rate, the massive air friction causes the individual particles to burn quickly, but the light we see is not due to combustion. It is impossible to see it because these small particles are burning at a height of 50 to 150 miles. The stripes we see are shining poles of air that are chemically excited by particles tearing through the particles. Sometimes these streaks appear as different colors to indicate the type of atmosphere gas that is temporarily generated.
The meteor shower looks best after midnight. It is flying from the side of the rotating earth to the comet remnants. It's like driving a cross country on a warm summer night. Get more bugs in the windshield than in the rear window. After midnight we are facing the "windshield" of the earth we are traveling to.
Leonid meteor shower was not named after Soviet President Leonid Brezhnev. They are called Leonids because the star in the meteor appears in the sky as Leo the Lion. After midnight Leo hangs in the eastern sky and looks like a question mark backwards. That does not mean that oily hunting should be restricted to that area of ​​heaven. You will miss many because a meteor can appear anywhere in the sky.
The best way to see a Leonid or other meteor shower is to place a blanket on a lawn chair after midnight. After a couple of hours in the morning, we have to see the night sky and see a few. The meteor where you are situated at the given time. Interesting group or family activity.

Earlier this weekend, the new crescent moon fits next to a bright planet Venus in the low southwestern sky. This weekend, the month of the first quarter is really close to Mars on the evening sky in the evening. On Thursday, the moon will be on the lower right side of Mars, and on Friday Mars will be parked on the upper left of the red planet.
