How did corona borealis get its name?
Corona Borealis was named by the Ancient Greeks because its shape resembles a crown, with "corona" meaning crown in Latin and "borealis" indicating its northern location in the sky. The constellation is often associated with the myth of Ariadne, the daughter of King Minos of Crete, who was later placed in the sky as a wedding gift from Dionysus.
What is the cause of the Aurora Australis?
The Aurora Australis - Southern Lights (and the northern hemisphere's Aurora Borealis) are caused by the interaction of Earth's magnetic field with the flow of highly-charged particles from the Sun (known as the "solar wind"). Collisions of these particles with atmospheric molecules causes energy emission as visible light.
Auroras are normally confined to polar regions, which are nearer the magnetic poles.
When magnetic storms occur on the Sun, when electrically charged particles (ions) from the corona and solar flares are added to the solar wind produced by the corona, the charged particles are accelerated by the Earth's magnetic field interact with the gases in the upper atmosphere and cause the gas molecules to emit light. Electrons in the molecules are excited to higher energy levels and then release photons when the fall back to lower energy levels.
Why is the Aurora Borealis named after a Greek god?
The Aurora Borealis is named after the Roman goddess of dawn, Aurora. It is believed that the name Aurora was attached to this natural phenomenon due to its glowing appearance in the sky, resembling the colors of the sunrise. The term "Borealis" indicates the northern location where this light display is most commonly seen.
What region of the atmosphere where auroras occur?
Auroras occur in the thermosphere, which is the region of the atmosphere located between the mesosphere and the exosphere. This is where charged particles from the sun interact with gases in the Earth's atmosphere, creating the colorful light displays known as auroras.
Auroras change color due to the type of gas molecules in the Earth's atmosphere that are being excited by solar wind particles. Different gases emit different colors when they are energized, resulting in the vibrant displays of colors in the auroras.
Can you see the Aurora Borealis from the Philippines?
Aurora Borealis means Northern Lights. Philippines is near the equator, so you can not see Northern Lights from the Philippines. IF the Earth tilts more, it may be possible we can see an Aurora Borealis/Australis
When can you see the Aurora Borealis?
There isn't really a schedule of auroras; they happen when a stream of charged particles from the Sun interact with the Earth's magnetic field.
Watch the website at spaceweather.com (see the link below) and look for "coronal mass ejections"; bright auroras often follow about 2 days later.
But they sometimes are visible without any warning, because the Sun is CONSTANTLY sending out masses of charged particles.
Can auroras only occur at night?
Auroras can occur during the day or night, but they are typically easier to see at night when it is dark. However, strong solar activity can sometimes create auroras that are visible during the daytime as well.
Do Auroras occur in the ionosphere?
Yes, auroras occur in the ionosphere. They are caused by the interaction of charged particles from the sun with the Earth's magnetic field and atmosphere, creating a colorful display of light. The ionosphere, being part of the upper atmosphere, plays a key role in facilitating this phenomenon.
When did the northen lights start?
the aurora borealis starts on our nearest star, the sun .on the sun, extremly hot gas particles are very exited. they create a state of matter, called plasma.this plasma escapes the suns corona, or atmophere.
What is the longitude and latitude of aurora borealis?
Aurora Borealis occurs with a center around the North Pole, and on clear, moonless nights during extreme solar wind periods, can be seen everywhere on Earth south of the Arctic Circle.
There is no longitude or latitude for the Northern Lights.
Since the Northern Lights are caused by the atmosphere, they are constantly changing and moving. They cannot have an exactlatitude and longitude because they are almost never in the exact same spot.
What is it called when its really colorful in the sky in Antarctica?
There are several 'really colorful' events in the skies over the Antarctic continent, in addition to sunlight, starlight and moonlight.
When the sun is up, you can see sun dogs, that Wikipedia describes as: "... the scientific name parhelia (singular parhelion), are an atmospheric phenomenon that creates a pair of bright spots of light on either side on the sun, often co-occurring with a luminous ring or halo." Sun dogs are also visible in less polar, but high-latitude geographies on earth.
When there is no sun, Aurora Australis are visible during the dark periods, and from Wikipedia: "The aurora is produced by solar wind particles guided by Earth's field lines to the top of the atmosphere."
When there have been no sunrises, once the sun does rise -- once again from Wikipedia, below -- "Polar stratospheric clouds or PSCs, also known as nacreous clouds, are clouds in the winter polar stratosphere at altitudes of 15,000 to 25,000 meters (49,000 to 82,000 ft)."
Why did baler tayabas became Aurora?
In 1951, the Sixth Congress enacted Republic Act No. 648, renaming the province of Tayabas to Aurora in honor of Aurora Aragon Quezon, the wife of President Manuel L. Quezon, who was known for her philanthropic efforts and contributions to the community.
How often do the Northern Lights or Aurora Borealis happen in Nova Scotia?
It is caused by the showers of particles spraying out of the sun and captured by the magnetic field of the earth. So it is not actually on a regular schedule, and actually is happening constantly, but is best seen at night. The brightness and extent is determined by how charged the particles are.
The closer you are to the north magnetic pole the more often you will see it.
Auroras are caused by what hitting the atmosphere?
Auroras are caused by charged solar particles colliding with atoms of oxygen and nitrogen in the ionosphere, which is the highest level of the atmosphere.
How many colours in a northern lights?
The Northern Lights display an array of colors including shades of green, pink, purple, yellow, and blue. The specific colors depend on the gases in the Earth's atmosphere colliding with solar particles.
Do the northern lights emit a sound?
No, the northern lights do not emit a sound. The light phenomenon is a result of charged particles from the sun colliding with gases in Earth's atmosphere, producing beautiful colorful light displays but no sound.
When was the first Aurora borealis sighting?
Auroras are a natural occurence and have been around for longer than humans have. This question is kind of like asking "When was the first snowfall observed?"...there is no "first observation".
How is aurora related to solar wind?
The solar wind produces a number of charged particles. These charged particles crash into the atmosphere at the magnetic north pole. When a particle from the solar wind hits an atom in the atmosphere, it knocks an electron from its outer shell. When the electron bounces back to where it belongs, it gives off light. That light is the Aurora.
How high in the sky does a Auroras start?
Auroras typically occur in the thermosphere, which is about 80 to 500 kilometers above the Earth's surface. The light show happens when charged particles from the sun collide with gas molecules in the Earth's atmosphere, causing them to emit colorful light.
What does the Aurora Australis look like?
The Aurora Australis is a natural light display in the Southern Hemisphere, similar to the Northern Lights. It appears as colorful shifting curtains of light in the night sky, typically in shades of green, pink, and purple. It is caused by solar particles interacting with the Earth's atmosphere.
Is the light before sunrise called aurora?
No, the light before sunrise is called the dawn or twilight, not the aurora. The aurora refers to natural light displays in the sky, predominantly seen in polar regions, caused by the interaction of solar wind with the Earth's atmosphere.
Northern lights and southern lights are other names for what phhenomenon?
Aurora australis for Southern, Aurora Borealis for Northern
Are Northern lights and aura borialis not the same?
Aurora Borealis and Northern Lights are both names for the same thing.
Where are northern lights located?
The Northern Lights, also known as the Aurora Borealis, can be primarily seen in the high-latitude regions close to the Arctic Circle, such as Norway, Sweden, Iceland, Canada, and Alaska. These natural light displays are caused by solar particles interacting with the Earth's atmosphere.
