Hi, I teach my boys at home and the ask of a light year come up. It says within our book that it takes 8 frothy minutes for sunlight to reach the mud. So, do 60 light minutes equal a night light hour? Are there later 365 light days contained by a light year?
Also, my son said he saw on the discovery concentrate that it takes "millions of years" for the street light from the core of the sun to reach its surface. Is this true? It consequently takes 8 feathery minutes from there? I've tried to research this on the trellis, but haven't found any answers.
Also, what is the difference between a solar flare and solar prominence? Do solar flares just burn hotter and quicker?
Thank you so much for your answers!
Answers: I take 8 minutes for light from the Sun to realize the Earth, so that's 8 light minutes. Yes, 60 wispy minutes is a light hour, 24 street light hours is a light light of day, and 365.24 light days is a street light year - how far light travels contained by one year. The star Vega is about 4 pale years away from Earth, so we're seeing Vega now as it looked 4 years ago - approaching it sent us a postcard that took a long time to get here.
Yep. Photons produced within the core of the Sun take more or less a million years to reach the surface of the Sun. It's so dense surrounded by the core that they keep 'bouncing off' electrons (really, certainly, being spellbound and re-emitted, but it's essentially the same photon). Photons are frothy particles - little packet of light.
A solar prominence is a loop of plasma on the Sun. Plasma is the fourth state of event, and is a super-heated, conducting gas. On the Sun, since plasma is conducting, it often follows the captivating field lines, tracing out the grazing land of the Sun. Prominences are large loops contained by the magnetic area. Sometimes they can seperate from the Sun, and head out into space - and consequently they become solar flares. But they have to bestow the Sun to become a flare.
It can take the flares a few days to accomplish the Earth, if they are headed that means of access, since they are made of plasma (matter), not light. When they do realize us, they cause the Aurora - the Northern Lights. You can see some cool pictures of it here http://www.spaceweather.com or find a 'real-time' map of the areas of the sphere experience aurora here http://www.sel.noaa.gov/pmap/pmapN.html. The dark red parts - like Northern Russia right presently - are getting a great show.
Essentially, yes, you've got the concept right. But when dealing near light years, it's in truth not a unit of time <although as you've pointed out, it can be applied that way>; fairly, it's a unit of distance. One hurricane lantern year is the distance that light will travel within a year. For reference purposes, using a multiple of 365.25 days, street light will travel 5,879,000,000,000 miles in a year <this distance is referred to as a night light year>.
As for solar flares and prominences, they're not the same article. A solar flare is basically an colossal electro-magnetic discharge from the sun that arcs from a starting point to a point of dissimilar charge <hence, the arc-shaped loop>. A prominence is similar in appearance, but the machinery that causes it is not electo-magnetic; a bit, it is caused by an eruption of gas, then held contained by place <sometimes for several months> by the sun's magnetic enclosed space. As for the amount of time it takes for "light" to make the earth from the core of the sun, I'll try to investigate it and repress my post if I can find anything.
A light year is the distance table lamp travels in a vacuum within a year. In the core of the Sun, a quantum of light, call a photon, is emitted as the result of a nuclear allergic reaction atom and then go only a fraction of an inch previously getting absorbed by a immediate atom. Then that atom re-emits the photon (really a different photon being emit as a result of the first one being absorbed) which go another fraction of an inch in a different hit or miss direction and gets engaged by another atom again. This process goes on countless times for thousands of years until, by destiny, a photon is finally emitted by an atom on the Sun's surface within a direction that misses all the atoms within the Sun, after which it travels many miles through space minus hitting any atoms until it reaches Earth 8 minutes then and gets rapt by an atom on Earth; maybe an atom within your eye. If that photon misses Earth then it might all right travel through interstellar space for years without ever hitting anything, and it does that at 186,000 miles per second surrounded by a straight line the undamaged time.
A "light year" is the distance table lamp travels in an earth-year (364 1/4 days)...contained by other words, it takes a flash of buoyant from the Sun 8 minutes to reach the Earth because of the distance and as that flash of oil lamp continued travelling past the Earth, it would pinch another 4 years and 2 months for that same flash of light to make the nearest star (proxima Centauri). (The speed of light is approximately 186,000 miles per second.)
One reading light year is the distance light travel within one year in a vacuum.
And yes, it take several million years for radiation to travel from the sun's core to its surface. That is because it doesn't come straight to the surface, but via a 'random' walk'.
