What is it in the night sky that blinks blue red white and green?

Answer 1

Among the many types of particles and electromagnetic radiation of many wavelengths

that issue forth from stars, "visible" light is typically included.

When your eyes are not dazzled and "stopped down" by nearby bright objects, such as

the sun, the moon, and streetlights, you're able to perceive the visible light emanating

from stars that are near enough to Earth so that their light arrives here with an intensity

that exceeds the typical sensitivity threshold of human perception.

Having the star positioned above your local horizon also helps.

Answer 2

Red sky at night refers to the old mariners proverb: "Red sky at night, sailor's delight. Red sky a'morning, sailor take warning." This bit of nautical wisdom is based on the idea that clouds in the east at sunrise portend stormy weather whereas clouds in the west at sunset promise fair weather. This being due to the fact that weather fronts tend to travel from east to west in the northern hemisphere.

I definitely have heard the saying, Red skies at night, sailor's delight, Red skies in the morning, sailors take warming. I don't know about the explanation. The United States is in the northern hemisphere. If you look at the weather map, day after day it looks like the weather mostly comes in from the west.

Answer 3

There are a great number of red stars, plus one red planet that often LOOKS like a red star. The red planet is Mars, of course, and is visible at this season (Sept 1, 2012) low in the western sky after sunset.

The most notable red STAR is Betelgeuse, which is at the left shoulder of Orion the Hunter.

Answer 4

I am central Alberta and the time is 9:30 pm on the very cold night of February 24th. I am sorry to say that I am a smoker and always go outside to have my cigarettes. I watch this thing every night! It is in the South Eastern sky. I have NEVER seen as I did tonight! I yelled at my husband to quickly come see what I couldn't believe my eyes were seeing! It has always been blinking; red, blue, white and green, but tonight I swear it was a horizontal line! What the heck is this?! Isn't there some specialists in this field out there somewhere that can tell us!? I know that I am not improving this answer, but I thought that someone else might find this interesting...

the red star in the night sky is mars" I am in Surrey, B.C. Canada, and I can see the same flashing star in the night sky. I don't think that it is mars. It is 330am, and it is in the same position relative to another star, much brighter and more constant, that it was the night before. It does flash red white and blue. At least it seems too. There is also some kind of trick on the eyes, as it almost seems to waiver in place.

If it doesnt change in position relative to other stars, it cannot be a planet. Perhaps... From my location, it is approximately south. It is almost as if it is being eclipsed every few seconds. Could it be a binary system? Or worse, is it a meteor travelling directly towards us? Waiting for the answer.

The lights are aircraft, government drone planes. I have been seeing the flashing lights for over a year, one night it finally came at me and I caught it on my camera phone, check out the above link. I've seen them around our military base where I work. The color of the lights would make sense due to aircraft standards as well. Like I said, I had a first hand sighting so Im confident in what I saw.

Answer 5

A blow to the head may cause one to see stars, temporarily. The occipital lobe is located at the back of the head. Damage to this area of the brain can make one go blind (or dead). But a blow or concussion may produce fleeting visual hallucinations interfering with the brain's normal interpretation of light.

Answer 6

During the day it is too bright to see any, because of the sun, which itself is a star. The ones we see at night change, because we are orbiting the Sun, so we are in effect looking at the sky from a different location at different times. However, what you see at one time in a year, you will see at the same time every other year. So it is always possible to know what you can see at different times of the year.

Answer 7

Probably an airplane. Aircraft have red and green navigational lights on the wingtips, and a red rotating beacon on the top. Many airplanes also have a brilliant white strobe light, which could appear to be blue.

Answer 8

The sky is red because of the sun.

When the sun is low in the sky (on/close to the horizon) not much light reaches the whole side of the earth you're on.

Therefore, the sky is red.

Answer 9

You might see shooting stars because there is a meteor shower in your area. Often, when these types of showers occur, many pieces of meteors will enter the atmosphere or pass near the atmosphere in a short period of time.

Answer 10

The moon and/or lights of cities, towns etc.
