NASA Detected Artificial Light from Another Planet
Hundreds of diplomatic spaceships take off from earth and head into space when they reach their destination they're met by hundreds of alien ships this is humanity's first contact with an extraterrestrial civilization people managed to detect them not so long ago in a star system very close to our home it's proxima centauri this red dwarf .
Star is the closest to our solar system it's seven times smaller than our sun which makes it only fifty percent bigger than jupiter proxima centauri is also eight times as light as the sun this star system is 4.2 light years away that's how long it takes a photon of light to travel from this star to earth by comparison it only takes eight .
Minutes for sunlight to reach our planet if you decided to travel to proxima centauri it would take you about 73 000 years to fly there in a conventional rocket that's longer than our intelligent civilization has even existed but it's not the star itself that interests us it's the planet orbiting it that's proxima centauri b .
It's 17 bigger than earth and about 10 percent heavier it orbits its star at a distance of 4.5 million miles by comparison earth is 93 million miles away from the sun that's 20 times farther but the host star proxima centauri is a red dwarf it doesn't emit as much light and heat as our sun so the planet .
Proxima centauri b is right in the habitable zone of the star it's located at such a perfect distance from its mother star that the planet neither gets too hot nor turns into a block of ice in other words the temperature there makes it possible for water to exist in its liquid state this means that proxima centauri b could host life .
But further observations of the planet may get doubtful the host star is very unstable its brightness changes too frequently in 2017 astronomers witnessed a catastrophic flash the star increased its brightness by 1 000 times for 10 seconds before that it was another weaker flash the planet received an enormous amount .
Of radiation if there had been life there that flare would have wiped it out completely overall proxima centauri b receives about 400 times more x-rays than earth complex living organisms cannot live under such conditions scientists say that even if there was an atmosphere and an ocean on proxima .
Centauri b this constant radiation would simply blow them off the planet proxima centauri b is so close to its host star that it's gravitationally locked to it this means that the planet is always turned to the star with only one side just like the moon is turned toward earth that means that only one .
Side of the planet receives this awful amount of radiation and some experts speculate that an intelligent civilization might live on the night side of the planet and it could be this civilization that sent us the strange signal that astronomers caught in 2019 scientists described it as quote a .
Bright long-duration optical flare accompanied by a series of intense coherent radio bursts this radio signal was observed for 30 days by one of the radio telescopes on earth scientists thought the signal was artificial and could have been sent by an extraterrestrial civilization .
Presumably the signal came from proxima centauri b or one of the moons that might be in that star system but further observations failed to detect the signal now the main theory claims that this radio signal is just some kind of interference from some technology on earth but what if it was really sent by .
A civilization living on the dark side of proxima centauri b well we may soon find out for sure people are launching a brand new telescope into space it's the james webb space telescope it's scheduled to be launched at the end of 2021 a booster rocket will take off from earth and reach orbit .
Then it'll deliver the telescope to a specific point between our planet and the sun where their gravitational forces are roughly equal plus there's no light pollution in space unlike on earth's surface there are also no clouds or other weather conditions that might interfere with the telescope .
The james webb space telescope will replace the hubble telescope which has been operating in space since 1990. the new telescope cost 9.8 billion dollars and here's why it'll use a mirror as wide as a boxing ring this will allow the telescope to see very far into space so far in fact that the light from some .
Events happening there won't have reached earth yet this means we will literally be able to look back in time the james webb space telescope will see the universe almost immediately after the big bang we'll see how the first stars and galaxies were born and how the universe .
Turned into what we observed today but also this telescope can be used to examine proxima centauri b astronomers will be looking for artificial light there like the led lights we have on earth if proxima centauri b really hosts life on its night side then the locals must have learned to transfer heat and light from .
The day side of the planet and they would have to use artificial light to support life on their side the james webb space telescope is powerful enough to distinguish the light waves emitted by the star from those that might be created by someone on the dark side of the planet and if we do detect some artificial light we'll have .
The first ever confirmation that an intelligent civilization might exist outside our solar system but there's always room for error and calculations and data interpretation the only way to establish the truth once and for all is to send a space probe to proxima centauri then we can get real pictures of the planet .
The main problem is distance although proxima centauri is the closest to the earth star system it still takes tens of thousands of years to get there after all the voyager 1 space probe needed about 44 years just to leave the solar system and that's just a small step compared to the actual distance to the nearest star .
So we need other methods of travel and they have to be much faster some scientists want to send micro probes to proxima centauri b they won't be any heavier than a sewing needle a launch vehicle will deploy about a thousand of these probes into orbit then they will unfold a space sail this is an ultra light material that .
Will use the power of light to create thrust when the sail is deployed we'll focus a powerful laser beam onto it this will accelerate the probes to about 20 percent of the speed of light this will be an absolute speed record by our standards but it'll still take about 21 years for these probes to reach their .
Destination and we'll have to wait for about four more years just to get the first signal from them the proxima centauri star system isn't the only potential world to host life and one of the tasks of the james webb space telescope is to look out for other worlds the telescope's powerful .
Instruments will allow it to find relatively cold planets where temperatures are close to those on earth we'll be able to study in detail around two dozen nearby star systems and will be able to detect not only planets themselves but also their moons scientists expect a boom in the discovery of exoplanets from the start .
Of the telescope in 2022 we'll constantly be detecting new worlds and learning more about those already discovered the james webb space telescope will allow us to better study our own solar system jupiter's moon europa for example scientists believe there might be water there although europa looks like a block .
Of ice the moon's gravitational interaction with jupiter heats its core that likely makes the ice deep below the surface melt so there's likely to be an ocean under the ice crust similar conditions could exist on enceladus saturn's moon this moon is geologically active there are geysers that burst out of the cracks .
On the moon's surface the james webb space telescope's infrared instruments will be able to explore europa and enceladus in search of biosignatures those are the traces of life activity of living organisms or bacteria this telescope is scheduled to operate for about six years but in the future .
We'll launch an even bigger one it's called luvoir which stands for the large uv optical infrared surveyor its mirror will be twice the size of that of the james webb space telescope and almost seven times the size of the hubbles the telescope is scheduled to be launched in 2039 we'll get it into orbit with the help of .
A super heavy rocket then we'll have to deliver the telescope to its destination one million miles away from earth and then it'll begin its observations we could learn to travel faster than the speed of light by that time then if we find a potentially habitable planet with the help of the telescope we can send a space probe or even a team of explorers .
There in this case a diplomatic meeting with an extraterrestrial civilization might become a reality
Proxima Centauri b is in the habitable zone and is pretty similar in mass to the Earth. NASA’s telescope might have detected proof of artificial lights coming from that planet. What is it? A distant megapolis or maybe lights from some vehicles? Or some sort of signal we might be receiving? #brightside Credit: GSFC/NASA Andrew Jones/NASA Animation is created by Bright Side. —————————————————————————————- Music by Epidemic Sound https://www.epidemicsound.com Check our Bright Side podcast on Spotify and leave a positive review! https://open.spotify.com/show/0hUkPxD34jRLrMrJux4VxV Subscribe to Bright Side: https://goo.gl/rQTJZz —————————————————————————————- Our Social Media: Facebook: https://www.facebook.com/brightside Instagram: https://www.instagram.com/brightside.official TikTok: https://email@example.com?lang=en Stock materials (photos, footages and other): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru —————————————————————————————- For more videos and articles visit: http://www.brightside.me
