What color was the streaks in the Lyrid Meteor Shower?

It was almost like a rainbow of colors, from blue to red. It was mostly blue though.

look here: http://skytonight.com/observing/skychart/3308911.html\n\nOr here for a simpler one just for the month of November:\nhttp://www.accd.edu/sac/ce/scobee/StarChart.htm\n\n\nAfter looking it seems to be below the horizon for the northern hemnisphere. It is up during the day but the Sun drowns out the light coming from the stars.\n\nHere is it's placment in the sky: http://en.wikipedia.org/wiki/Leo_%28constellation%29\nIt is just south of the Big Dipper (Ursa Major) so it may be up in the early morning.\n\n\nEDIT:\nIf you are looking for the meteor shower see here:\nhttp://www.space.com/spacewatch/061117_leonid_guide.html\n\n\nIn North America, for the Maritime Provinces of Canada, New England, eastern New York and Bermuda, the Sickle of Leo (from where the Leonids appear to emanate) will be above the east-northeast horizon just as the shower is due to reach its peak.  But because Leo will be at a much lower altitude compared to Europe, meteor rates correspondingly may be much lower as well.  However, this very special circumstance could lead to the appearance of a few long-trailed Earth-grazing meteors, due to meteoroids that skim along a path nearly parallel to Earth's surface.

The gases of the Sun extend far beyond the photosphere, which may be considered the lowest level of the solar atmosphere. The region immediately above the photosphere is called the chromosphere. \n\nObservation of the Chromosphere:\nThe chromosphere is 2000-3000 km thick. It glows faintly relative to the photosphere and can only be seen easily in a total solar eclipse. When it can be seen it is reddish in color (because of strong Balmer H-alpha emission). This color is the origin of its name (chromos meaning ``color''). \n\nThe faint flow of the chromosphere is due to an emission spectrum from hot, low density gases emitting at discrete wavelengths. The discovery of helium noted earlier was from emission lines seen in the chromosphere during an eclipse in 1868. This new element was only found on the Earth in 1895. \n\nSpicules:\nThe chromosphere contains spikes of gas called spicules that rise through it. The adjacent image shows spicules on the limb of the Sun as imaged by the Big Bear Solar Observatory (Ref). This image is a superposition of 11 limb images taken at different wavelengths (click on the image for a larger version that shows the spicules more clearly). In this image the longest spicules rise about 7000 km. Spicules are short-lived phenomena, corresponding to rising jets of gas that move upward at about 30km/sec and last only about 10 minutes.

The Leonid meteor shower is predicted to peak at around 4:45-5UT on the 19th with a rate of about 100 to 150 meteors per hour.  This translates to about 10:45 to 11pm on the 18th in Kansas I think.  Unfortunately, the Leonid radiant (the point from which the Leonids appear to originate) is the constellation Leo -- which, in Kansas, does not rise until AFTER the peak.\n\nBut you will still be able to see some meteors after the radiant rises -- you just won't be able to witness the predicted maximum.  So if you have clear skies, go for it!

it ain't pretty but here goes nothing.\n\n\n\nsunlight is all hues\nN and O scatter the light\nblue is spread the most\n\n\n\n\nThe first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them. \n\nThere is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors. \n\nSo when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)

I am not going to pick any of those choices because I don't believe any of those are correct, including streak. What you are describing is crystal structure, which might be related to color and streak, but since trace impurities in a mineral often determine color, and streak is nothing more than the color of a powdered form of the mineral I don't think It will be determined by atomic structure with certainty.  Most streaks are white!\n\nCleavage would be a correct answer but it was not included above. Cleavage and crystal structure are closely related properties. \n\nWhat you have described is the crystal structure. All minerals can be classified within 14 basic crystal lattice arrangements of the atoms in three dimensions. These 14 lattice arrangements fit within 7 larger crystal systems, allowing the classification of atomic structure of all known minerals.  To see diagrams of these go here:\nhttp://en.wikipedia.org/wiki/Crystal_structure

a meteor is going to pass very close to the earth on that day...check out\nhttp://english.ohmynews.com/articleview/article_view.asp?at_code=341846

Stars are like our Sun. Not comets at all. Comets are dirty, big snowballs that have no light at all. The twinkling comes from heat radiating from earth which makes the light spectrum shift in different colours. Symbols that represent something doesn't often look like the original. Take the symbol for a heart for example. But it's easy! :) Try to draw a immensly huge boiling, burning piece of gas that throws tons of particles out from it in lightning speed and see if anyone understands what you drew. Now try to make it into a character that you can type on a keyboard :)

Thank you so much! It's been some years since I caught the Leonids, and it's really hard to catch anything at all when living in the city. This video really made up for what I missed and the spectacular fireballs took my breath away.\n\n2001 was the best Leonid display I ever saw and I'll never forget it when the peak hit and the sky filled with streaks and occasional fireballs.\n\nThanks so much again! You made my day!

A meteoroid is a relatively small (sand- to boulder-sized) fragment of debris in the Solar System. When entering a planet's atmosphere, the meteoroid heats up and partially or completely vaporizes. The gas along the path of the meteoroid becomes ionized and glows. The trail of glowing vapor is called a meteor, or shooting star. If any portion of the meteor survives to reach the ground, it is then referred to as a meteorite.79% of meteorites are Chondrites - balls of mafic minerals with small grain size indicative of rapid cooling. In most chondrites small spherules, called chondrules, can be found. Chondrites are typically about 4.6 billion years old and are thought to represent material from the asteroid belt. It is unknown how they formed. Carbonaceous Chondrites, thought to be unaltered solar nebula material, constitute about 5% of meteorites and contain small amounts of organic materials, including amino acids. Also, presolar grains are identified in carbonaceous chondrites. The isotope ratios of carbonaceous chondrites are similar to those of the Sun.Achondrites are similar to terrestrial mafic igneous rocks and sometimes are brecciated. Achondrites constitute about 8% of the incoming material and are thought to represent crustal material of larger asteroids. About 6% of meteorites are iron meteorites with intergrowths of iron-nickel alloys, such as kamacite. Unlike chondrites, the crystals are large and appear to represent slow crystallization. Iron meteorites are thought to be the core material of one or more planets that subsequently broke up. Stony iron meteorites constitute the remaining 2%. They are a mixture of iron-nickel and silicate minerals. They are thought to have originated in the boundary zone above the core regions where iron meteorites originated. A small number of meteorites belong to additional groups or subgroups with unique chemical characteristics relative to other members of the larger groups, such as Lunar meteorites or Martian meteorites.

Meteor showers can be disappointing if your skies are cloudy or if you live in the wrong location. This weekend's Leonid meteor shower, for example, will be best viewed from parts of Europe and eastern North America.\n\nSkywatchers elsewhere, including western North America, should see a typical rendition of the annual show—a few meteors per hour—but will miss the peak flurry, expected to start around 11:45 p.m. ET and last a couple hours.\nhttp://www.space.com/spacewatch/061116_leonids_listen.html\n---------------\nHow can I best view a meteor shower?\n\nIf you live near a brightly lit city, drive away from the glow of city lights and toward the constellation from which the meteors will appear to radiate. \nFor example, drive north to view the Leonids. Driving south may lead you to darker skies, but the glow will dominate the northern horizon, where Leo rises. Perseid meteors will appear to "rain" into the atmosphere from the constellation Perseus, which rises in the northeast around 11 p.m. in mid-August. \nAfter you've escaped the city glow, find a dark, secluded spot where oncoming car headlights will not periodically ruin your sensitive night vision. Look for state or city parks or other safe, dark sites. \nOnce you have settled at your observing spot, lay back or position yourself so the horizon appears at the edge of your peripheral vision, with the stars and sky filling your field of view. Meteors will instantly grab your attention as they streak by.\nhttp://stardate.org/nightsky/meteors/

The aurora is a glow observed in the night sky, usually in the polar zone. For this reason some scientists call it a "polar aurora" (or "aurora polaris"). In northern latitudes, it is known as "aurora borealis" which is Latin for "northern dawn" since in Europe especially, it often appears as a reddish glow on the northern horizon as if the sun were rising from an unusual direction. The aurora borealis is also called the "northern lights". The aurora borealis most often occurs from September to October and March to April. Its southern counterpart, "aurora australis", has similar properties

i think white is all the reflected light . apollo space mission pics show grey shades.

Comets, as several people have pointed out, are large bodies of rock and ice that orbit the sun. When they come close enough to the sun, energy from the sun causes some of the ices to vaporize, causing a visible coma (cloud around the nucleus) and tail, consisting of gas and dust.\n\nA meteor is the streak made in the upper atmosphere by a bit of high-velocity space debris. The bits of debris themselves are called meteoroids. The ones that produce predictable meteor showers are clouds of dust shed by comets. Other meteoroids are  pieces of primordial matter that never accreted into planets, or chunks of matter broken off of larger bodies by impacts with asteroids. \n\nA meteoroid that makes its way to the surface of Earth is called a meteorite. They can be stony, metallic, or both. Some meteorites have been identified as coming from Mars and the Moon.

You're obviously not looking hard enough!  After it's been raining (not this week) and the sun is coming out again, look at a cloud, a dark one is better than a light one, and you should be able to see how the edge of the cloud appears to be lined with silver

Lightning can be any color. It is reflected off things that are near it, so it could be any color.
