The total number of exoplanets in the milky Way galaxy has over 100 billion. Exoplanet is a planet located outside our solar system. Currently, the scientists opened only a small proportion of them. About 10 of the most incredible planets in this post.
The darkest exoplanet – a distant, Jupiter-sized gas giant called TrES-2b.
The measurements showed that the planet TrES-2b reflects less than one percent of light, making it blacker than coal and darker naturally any of the planets of the solar system. Work on this planet, was published in the journal of the Royal Astronomical Society Monthly Notices. Planet TrES-2b reflects less light than black acrylic paint, so this is truly a dark world.
The largest planet ever found in the Universe is TrES-4. It was discovered in 2006 and it is located in the constellation Hercules. The planet is called TrES-4 orbits the star, which is at a distance of about 1,400 light years from planet Earth.
Researchers claim that the detected diameter of the planet by almost 2 times (actually 1.7) larger than the diameter of Jupiter (the largest planet of the Solar system). The temperature of TrES-4 1260 degrees Celsius.
A year on COROT-7b takes just over 20 hours. It is not surprising that the weather in this world, to put it mildly, exotic. Continue reading
The question that you will get the answer on this page: what is the biggest planet in the Solar system? Answer: Jupiter is the largest planet in the Solar system . It is the largest by mass, volume, area and many other statistics. Read this article to the end and you will learn many interesting facts about the planet and other objects in the system Jupiter.
Statistical data is the biggest planet in the Solar system
Here are some basic statistics about Jupiter, since the masses: mass 1.8981 x 1027 kg, volume — 1,43128 × 1015 km3, surface area — 6,1419 x 1010 km2, the average circle — 4,39264 x 105 km, and Despite its size, its density of only 1,326 g/cm3, which is only a quarter the density of Earth. Such low density is one of the factors by which scientists were able to determine that Jupiter consists mostly of gases and probably does not have a solid core.
Jupiter is the biggest planet in the Universe
Comparative sizes of Jupiter and TrES-4
However, Jupiter is the biggest planet in the Universe. TrES-4 is superior to the size of Jupiter in 1.4 times. Scientists suggest that a gas giant could be 15 times more massive than Jupiter before the fusion reaction that turns him into a brown dwarf. Continue reading
The Agency officially confirmed that funds the development of technology for bulk printing in zero gravity. It is assumed that the spider robots-3D printers can right on orbit to create individual segments of future space stations and gather them into a single unit already in 2020.
The aim of the project is to create a 3D printer that can print a design of polymers and other materials in the absence of gravity, extremely harsh temperature and radiation regimes. You need to solve the problem of fixing the layers of the printed elements and their proper solidification in conditions such as very low temperatures away from direct sunlight and high temperatures under solar radiation. It is obvious that the company Tethers Unlimited, which is the contractor on the project, any idea how to achieve this because, judging by the presentation of NASA’s first robotic printer should begin construction in orbit in 2020.
Look these robots would be weird, but functional. The management platform will have multiple articulated gripper through which the robot will be recorded on the created design, and move along it. On the platform will be attached to the container with the source, a printing device, a small unit of solar panels, batteries, and actually the system control and communication. The robots will need to synchronize actions among themselves,to be able by joint efforts to collect from disparate parts of the overall design. Continue reading
David Levi: a Guide to the starry sky
Comets, the “tailed stars”. From time to time in the starry sky appear of the comet, which got its name from the Greek word “kometes” “tailed”. Often, the comet took over some otherworldly forces and beings, in the Christian era, they attributed divine the meaning and was considered God’s messengers – angels. The Slavs we, the Germans existed beliefs – seeing a shooting star to pray, convinced that any desire expressed at the short time, while star rolling, will come true. Comet was brought in to the stars also called tailed stars or sirkali with a broom, the Germans schweifstern, haarstern (hairy star) and pfauenschwanz (peacock tail) ; Lithuanian songs mention the comet, as old men with long beards, whose appearance portends something extraordinary. Thus, on the basis of different similes light strip cast by the nucleus of the comet, the language gives it a tail, a broom or a beard. Rare comets made him unusual for people to connect with these tailed stars the idea of divine predvidenie of future troubles for their sins and the mortal call to repentance. Interesting review, made by Patriarch Nikon in-out, in 1664 at the monastery of the resurrection. Sitting at night in the sleigh, he began to atrasti the dust from your feet, remembering prominent Evangelical words: “the IDA also if you do not accept, basedfrom the hail and the dust stuck to your feet, shake off as a testimony against nya”. Streltsy Colonel, dressed escort of Nikon, said: we are the ashes we’ll sweep! – Let razmyat the Lord God you trade only a divine broom, who is on many days! – objected Nikon, pointing to the burning in the sky the comet. Humboldt in his “Cosmos” points to the poetic view, which in ancient times was connected with the comets: they saw shaggy stars and flaming swords.
Comets have the appearance of a small hazy spot with a light tail, and sometimes even several. Inside misty spot, called the head of the comet, sometimes shows a relatively bright nucleus, like a star. In fact the nucleus of the comet is a big lump of frozen gases, within which solid particles and a variety of sizes, from fine dust to large rocky masses. Continue reading
Space is what surrounds us far beyond planet Earth. In this small, thought the word so many mysterious and the unknown, what people have failed so far to understand. That is why the theme of the Universe (also called space) is so popular today. People don’t appreciate the opportunity to look daily at the magnificent beauty of the sky and stars, because not everyone knows about what is happening away from our eyes. Those who are still concerned about the cosmic Universe, pay dizzying sums of money for space flight. To look at the Earth from the height of the spacecraft, or to look at the bright flame of the stars of the Sun some people would pay from their pockets is really a lot of money, so no wonder why flights into space have become so popular. In this regard, entrepreneurial company several times a year organize cosmocore. One of the main reasons why “travellers” tend to visit the unknown spaces, in spite of serious physical training, is to get a lot of impressions and emotions. The longest space mission lasts up to 10 days, during which tourists arrive at the International Space Station. An interesting fact is that the path to the ISS lasts 2 times longer than back – all blagodarnyy of attraction of the Earth. To take a tour in space is still a difficult task for professionals but in a short time to humanity and it will be.
To get off the Ground and lifted up their galaxy may every inhabitant on this planet who is willing to undergo serious physical training, and, of course, to part with a certain amount of money. To departure do not require a visa or passport for more. But one who resides in the territory of the Russian Federation, it is necessary to legalize papers to arrive to the launch site, the Baikonur cosmodrome near Kazakhstan. The Russians are much more fortunate as visas, passports and stuff they need. Continue reading
