Secrets of TRAPPIST-1 System: Astronomers Reveal Planets Similar to Earth

An astrophysics researcher, Billy Quarles, has identified the possible compositions of the seven planets in the TRAPPIST-1 system.

By studying the compositions of "thousands of numerical simulations to identify the planets stable for millions of years, 

Quarles concluded that six of the seven planets are consistent with an Earth-like composition,” science journal reported.

The exception is TRAPPIST-1f, which has a mass of 25 percent water, signifying that TRAPPIST-1e may be the best candidate for future habitability studies.

In May last year, astronomers from MIT announced the discovery of an extremely unusual star system in the nearest region of Earth — TRAPPIST-1, which is only 40 light-years away from Earth in the direction of the constellation of Aquarius.

It was reported then that three planets revolving around this red dwarf, which presumably have a mass comparable to that of earth, are inside the so-called "zone of life" where water can exist in liquid form.

The scientists studied the spectrum of TRAPPIST-1 star beams, trying to understand the composition of the atmosphere of its planets, when they unexpectedly discovered that there were actually not three, but seven planets, six of them within the zone of life.

All these planets have almost "terrestrial" dimensions and have a Martian or terrestrial climate, except for the first planet, TRAPPIST-1b, which is more like Venus than Mars or Earth.

However, after further investigations it was discovered that one planet, TRAPPIST-1f, located in the center of the zone of life and considered one of the main candidates for the role of a twin of earth, is actually a "planet-ocean.”

Around 20-25 percent of its mass is water; this water, due to its proximity to the star, will be heated to very high temperatures and will cover the planet with a dense cloud of vapor, which will make the existence of life impossible on it.

All the other six planets are more similar to Earth – the proportion of water in their mass should not exceed several percent, and their insides should be composed of rocks similar in composition and density to terrestrial minerals.

The most suitable for life, therefore, is not TRAPPIST-1f, but its smaller neighbor TRAPPIST-1e, located slightly closer to the star.

In addition, life can also exist on the planet TRAPPIST-1g, which makes one revolution around the star in 13 incomplete days. 

The scientists plan to focus their efforts on these two planets in the future and they hope to obtain more accurate data on the composition and suitability of these planets for life.

Armenian protesters block traffic, railways & airport as protest leader loses PM bid

Anti-government protesters disrupted traffic in Armenia’s capital, blocking railways and roads leading to Yerevan International Airport, after the parliament voted against opposition leader Nikol Pashinyan’s bid for interim PM.
Protesters managed to block streets connecting downtown Yerevan to residential districts, disrupting transportation in Armenia’s capital, footage from the scene shows. 
Yerevan’s metro system has also been paralyzed as demonstrators sit on the tracks, preventing trains from passing.
Meanwhile, protesters disrupted traffic on a road leading to Yerevan’s Zvartnots International Airport, located just 12km from the center of the city. 
Consequently, some passengers had to go the rest of the way on foot in order to catch their flights, according to Sputnik news agency.
Railway services have also been disrupted all across the country amid the demonstrations, a spokesman for South Caucasus Railways confirmed to Interfax. 
Some other highways, including the one connecting th…

Iran Killing Command: The use of firearms in dealing with protesters

The document you see on the image is the order of the commander of the Tehran repressive force to all the units based in the city.

Based on this agenda, the mercenaries of the corrupt government Islamic Republic of Iran have been allowed to use firearms in the event of any protest movement against people by the regime.
This is a murder command.
The repressive force of the law, known to the world's famous police and guardians, should protect the lives of its citizens, by freeing their mercenaries, they allow them to murder Iranians who are protesting the corruption in the government and you have the important message that if you come to the streets in protest of corruption and torture and massacre, we will kill you.
Because, according to criminal Khomeini, maintenance of the system is obligatory.
A corrupt government that is so hideous that spend billions of dollars from the national treasury and popular capitalto the suppression of its people and the countries of the region, must be ov…

ایران فرمان قتل : دستور استفاده از سلاح گرم در برخورد با معترضان

سندی که در تصویر میبینید دستور فرمانده نیروی سرکوبگر انتظامی تهران به همه یگانهای مستقر در این شهر است.
بر اساس این دستور کار ، مزدوران حکومت فاسد نظام جمهوری اسلامی اجازه یافته اند که درصورت بروز هرگونه جنبش اعتراضی از سوی مردم علیه رژیم ، از سلاح گرم استفاده کنند.
این دستور یک فرمان قتل است.
نیروی سرکوبگر انتظامی که به ظاهر و تعریف شناخته شده پلیس در سراسر جهان ، میبایست حافظ جان شهروندان باشد ، با آزاد گذاشتن دست مزدوران چکمه پوش خود انها را مجاز به قتل ایرانیان معترض به فسادهای موجود درلایه های حکومت میکنند و این پیام مهم را در خود دارد که اگر در اعتراض به  فساد و شکنجه و کشتار به خیابانها بریزید شما را خواهیم کشت.
چرا که به گفته خمینی دجال، حفظ نظام از اوجب واجبات است.
حکومت فاسدی که انقدر وقیح هست که میلیاردها دلار از خزانه ملی و سرمایه مردمی را صرف سرکوب مردم خود و کشورهای منطقه میکند باید سرنگون کرد.
اکنون چهل سال است که کشور ما به اشغال این ملایان جنایکتارخونخوار و اسلام تحمیلی در آمده است .
هنوز باورش برای برخی سخت است که درک کنند کشور ما به معنای واقعی کلمه از سوی بنیادگرایان الله…
