10 most amazing Exoplanets

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.

TrES-2b

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.

TrES-4

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.

COROT-7b

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

NASA will print spacecraft in space

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
