Sympa

Avez-vous entendu parler du spectacle incroyable au-dessus d'Hawaï ? Récemment, un phénomène stupéfiant a fait qu'il semblait qu'une copie de la Voie lactée soit apparue dans le ciel nocturne. Les amateurs d'astronomie ont eu droit à une vue incroyable, avec les étoiles et la galaxie si claires qu'on aurait dit pouvoir les toucher. C'était comme une image miroir de la Voie lactée, juste au-dessus des îles. Si vous aimez l'observation des étoiles, c'était une nuit à ne pas manquer !

00:00We have, we humans, only one sun, only one moon, and apparently, only one milky way.

00:07Really?

00:09A mysterious thing has occurred that made scientists doubt this fact.

00:14On the island of Hawaii is an extinct volcano, the Mauna Kea.

00:18This is where the twin sister of the Milky Way was observed by a telescope.

00:23In the night sky, observers saw a mysterious spiral twirling in the shape of a galaxy.

00:29It really looked like the Milky Way.

00:32But it disappeared quite quickly, which left scientists perplexed.

00:37Some time later, they concluded that this spiral was not the twin of the Milky Way.

00:42It was only the result of the launch of a SpaceX rocket.

00:46Watch out!

00:48The lightning struck an isolated tree near the place where you were.

00:52It caught fire and a column of flames rose to the sky.

00:58As it does not rain, the column becomes higher and higher.

01:02Have you heard of this phenomenon?

01:05It is a fire tornado.

01:08It occurs when the wind starts to turn in a circle near the ground due to the difference in air pressure.

01:15These mini-tornadoes are generally easy to notice.

01:18Small gravel, dust, sand and leaves rise in the air and begin to fly in a fast circle.

01:25But then, if there is a fire nearby, the tornado can join it and lend it its power, like a whistle.

01:33The flames turn in a circle, rise higher and higher and end up creating a flaming whirlwind.

01:39Fortunately, fire tornadoes are short and do not cause much damage.

01:45Tornadoes can be extraordinary, but so can rains.

01:49If something can make me jump to the sky, it is a rain of spiders.

01:54And if you wonder if it really exists, well, the answer is yes.

01:59In Australia, rains of spiders are very common.

02:03The phenomenon is even called ballooning.

02:07The principle is as follows.

02:09Spiders capable of ballooning climb trees and large shrubs.

02:14They try to reach the highest point in a given area.

02:18Once at the top, they weave their web so that it can be carried by the wind.

02:25And here we go.

02:27Clinging to the strings of their webs with their little legs,

02:30the brave spiders rise in the air and fly towards a radiant future.

02:35Normally, humans do not notice these takeoffs, because spiders do not move in groups.

02:42You might be a little surprised if a spider suddenly landed on your nose.

02:47But it is generally quite rare to meet more than two of these travelers on the same day.

02:53However, when the weather is particularly bad, with a lot of rain or wind,

02:58thousands, even millions of spiders can decide that it is time to go to a more welcoming place.

03:05And they all fly away at the same time.

03:08This is when the rain of spiders occurs.

03:11Those who have witnessed the last rain of 2012 and 2015 tell me that it looks like a snowfall.

03:18Spiders descend slowly with their little parachutes and come to whiten the ground.

03:26Now imagine that you are looking out the window and that you see something incredible.

03:32A rainbow. But it is already night and the moon shines in the night sky.

03:37Ah, wait, that's exactly it. In fact, a lunar rainbow.

03:42Called moonbow in English, it is an extremely rare phenomenon.

03:46It looks like an ordinary rainbow, except that it appears in the moonlight after a downpour.

03:52Happy to have seen such a beautiful show, you fall asleep.

03:57The next morning, you look out the window again and suddenly, the sun is practically hidden.

04:03It looks like it's night again.

04:06You hear distant noises and a kind of croaking.

04:10Perplexed, you look up and, surprise, there are thousands and thousands of birds in the sky,

04:16so many that they block all the sunlight.

04:21This is what is called the black sun, black sun in Danish, a very appropriate name.

04:28Normally, this only happens in Denmark, hence the name.

04:31Or many migratory storks fly at the same time looking for a place to spend the winter.

04:37They are so numerous that they obscure the sky for a few moments.

04:41What they do near your home is a good question.

04:46Money does not grow on trees, but it can fall from the sky.

04:50It's the kind of rain I'd like to see one day. A silver rain.

04:54Such an event happened in Germany. People saw banknotes fall from a skyscraper.

05:00No one knows why this happened.

05:03Someone probably accidentally dropped a bag full of banknotes by the window.

05:08But that represented about 50,000 euros.

05:11People who were lucky enough to be surprised by such a rain turned out to be very honest

05:17and gave all these pretty rain drops, I mean these banknotes, to the police.

05:22Don't wait for the second downpour, find a job instead.

05:27All rains are not as pleasant as the one that pours money on your head.

05:33A rather unpleasant rain occurred in 1876 in Olympia Springs, in Kentucky.

05:41A certain Mrs. Crouch says she was making soap at home

05:46when suddenly pieces of raw meat began to fall from the sky.

05:51Some of these pieces were quite large, reaching more than 7 cm in diameter.

05:58She would have preferred fried chicken, but she was not asked for her opinion.

06:04Local newspapers reported that two people, having preferred to remain anonymous,

06:09had tasted the meat and concluded that it was sheep or goat.

06:13Months later, scientists decided to discover the truth about this strange phenomenon.

06:19The question became the subject of an animated debate

06:22until one of the researchers came to the most reasonable conclusion.

06:26The rain of meat must have been caused by the vultures flying over Bollaville at that time.

06:31These birds sometimes regurgitate their food in mid-flight,

06:35a defense mechanism, or simply to lighten their bodies, in order to fly faster.

06:40And that's what happened just above Mrs. Crouch's house, unfortunately.

06:46I love California.

06:48Let's teleport to Los Angeles.

06:50Do you see that?

06:51Almost above your head, a magnificent rainbow-shaped cloud cascade.

06:57This is what is called a fire rainbow, or horizontal arc.

07:02Once again, this is a rare phenomenon,

07:04but here, in Los Angeles, it is much more likely to occur than in Berlin, for example.

07:09Fire arcs only appear when all conditions are met.

07:14The place must be close to the equator,

07:16the sky must be clear,

07:18and there must be feather-shaped clouds in the sky.

07:21The position of the sun is also important.

07:24It must be more than 58 degrees above the horizon.

07:27These clouds are made up of ice crystals,

07:30and when the sun's rays reach them,

07:32the particles refract the light and create a rainbow.

07:38The moon no longer impresses you.

07:40You can see it in different places,

07:42in different sizes.

07:44But how does it change color?

07:46How can it be bright yellow one evening

07:49and dark red the next day?

07:52The moon, seen from the outside of the Earth's atmosphere,

07:56is a brownish gray.

07:58When we look at it above our heads,

08:00it usually appears bright and almost white.

08:03Because the light it reflects

08:05crosses a relatively thin layer of our atmosphere.

08:09Almost nothing blocks or refracts this light,

08:12which is therefore very bright.

08:14The moon can appear yellow, orange or even red

08:17when it is observed just above the horizon.

08:20It is the same effect that gives its color

08:22at sunrise or sunset,

08:24when the sun appears red.

08:27The light travels a much longer way

08:29to reach your eyes,

08:31and a large part of the blue spectrum is lost.

08:35The color of the light is then much warmer.

08:38The sun can also appear blue

08:41due to the presence of fine particles in the air.

08:44It refracts the light,

08:46and the moon never appears to us as it is above the atmosphere.

08:50But when the particles are bigger,

08:52they give the moon a bluish color.

08:55Finally, it also happens, very rarely,

08:58that the moon is purple.

09:00No one knows exactly why this happens,

09:03but astronomers think it is a combination.

09:06Atmosphere, more dust particles, more other things.

09:10We do not know more.
