are meteor showers shooting stars?

The short-lived trail of light the burning meteoroid produces is called a meteor. Meteors are commonly called falling stars or shooting stars. ... These events are called meteor showers and they occur when the Earth passes through the trail of debris left by a comet as it orbits the Sun.

In some nebulae, stars form out of large clouds of gas and dust; once some stars have formed inside the cloud, their light illuminates the cloud, making it visible to us. These star formation regions are sites of emission and reflection nebulae, like the famous Orion Nebula shown in the picture on the right.

A comet is a dirty snowball, a meteor is something that is going to hit the earths atmosphere at least and and asteroid is a rock floating around in space. Bigger space rocks are called asteroids or minor planets. ... A meteor is anything (comet or asteroid) that enters Earth's atmosphere and burns up.

Stars are formed from massive clouds of dust and gas in space. Gravity pulls the dust and gas together to form a protostar. As the gases come together, they get hot. A star forms when it is hot enough for nuclear reactions to start.

When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.

Star birth. Like people, stars are born, they grow old and they die. Their birth places are huge, cold clouds of gas and dust, known as 'nebulas'. The most famous of these is the Orion nebula, which is just visible with the unaided eye.

Meteors are often seen falling from the sky alone — one here, one there. But there are certain times in a year when dozens or even hundreds of meteors per hour will light up the sky, seemingly coming from one part of the sky, radiating in all directions, and falling toward Earth one after the other.

Most stars are much like the Sun—giant balls of gas burning billions of miles away. These spherical stars pump out a steady stream of light that crosses vast stretches of space before it illuminates the night sky.

A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. ... Very intense or unusual meteor showers are known as meteor outbursts and meteor storms, which produce at least 1,000 meteors an hour, most notably from the Leonids.

An asteroid is a small rocky object that orbits the Sun. ... A meteor is what happens when a meteoroid – a small piece of an asteroid or comet – burns up upon entering Earth's atmosphere, creating a streak of light in the sky. An asteroid is a small rocky object that orbits the Sun.

Why Do Stars Appear to Move in the Night Sky? ... These apparent star tracks are in fact not due to the stars moving, but to the rotational motion of the Earth. As the Earth rotates with an axis that is pointed in the direction of the North Star, stars appear to move from east to west in the sky.

If the meteor (shooting star) is large enough to survive the fall through the atmosphere, it cools and doesn't emit any visible light at all. ... A green glow, clearly visible in the trail of this shooting star, indicates the presence of burning copper.

Yet despite their apparent differences, there are similarities between them. Both are relatively small objects that have their origins in interplanetary space, orbiting the sun. A few meteorites may actually be fragments of comets, although such fragments are more likely to burn up as meteors in the upper atmosphere.

Analogous to the solar wind many stars have stellar winds. Because stars are so distant, stellar winds that are as gentle as the solar wind do not produce dramatic effects as seen from the earth. The stellar winds that we observe are therefore much stronger than the solar wind.

Well, no, stars are not on fire although they look that way. ... Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars.
1438608
Stars are made of very hot gas. ... Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements. Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen and iron, which were created by stars that existed before them.

The use of laser pointers is prohibited at some star parties and other astronomy gatherings. Always comply with such restrictions. Be aware of irresponsible uses of pointers so that the psychological effect will be minimized if you happen to be illuminated by one.
