The black gas giant of TrES-2b rotating round a star of the spectral class G0V GSC 03549-02811 was open by the transit Trans-Atlantic Exoplanet Survey method on August 21, 2006. The surprising planet is located at distance about 720-750 light years from Earth in zodiac the Dragon constellation. Opening of the gas giant TrES-2b was confirmed on September 8, 2006.
Astronomers were extremely lucky to find an exoplanet with a direct method.
It is quite difficult to find the exoplanet, which is far from our Solar System. For their detection astronomers use indirect methods, but this time scientists were very lucky. They managed to find huge massive exoplanet a direct method at the help of tools of a land telescope of VLT, which is in Chile.
Besides, scientists quite simply found exoplanet HD95086 b in constellation of Kiel on removal of 300 light years from Earth, they also photographed it. This planet lives in an orbit round the central star of HD95086.
The telescope Kepler found at once two potentially manned planets rotating round the general star. Only twenty years ago astronomers didn’t know about existence of similar planets, and the Solar system, even taking into account the latest discoveries in area of exoplanet, continued to be considered as the unique. However opening of planetary system at a star of Kepler-62 is capable to change this representation. Planets from this scattering differ by the size, and round a star they do a complete revolution for the period of 6 days to 9 months. Two most remote of these planets and the most suitable lives were open for emergence by the astronomer from the Washington University Eric Eygol. The most extreme, Kepler 62f probably a firm planet, by only 1,4 times of the continent, makes a turn round a star in 267 Earth days. Her neighbor, Kepler 62e, which has also got to a zone of a habitability, in 1,6 times more Earth, year on it makes 122 Earth days, and from a star she receives 20% more energy, than our planet.
Astronomers from Japan and New Zealand offered new strategy of search of the Earth-sized planets, which number in our galaxy scientists estimated at 100 billions pieces. Strategy is based on a gravitational microlensing method. In the research astronomers suggested to combine the information obtained from space observatory “Kepler” and as a result of application of a gravitational microlensing. The combination of two techniques will allow to find Earth-sized planets, which are in orbits from 0,5 to 10 astronomical units (distance from Earth to the Sun). The planet of the terrestrial sizes on considerable removal from a star can’t almost be found a transit method which is applied on a telescope “Kepler”. The space observatory fixes falling of brightness of a star when the planet passes between it and Earth. Thus, “Kepler” is capable to find about 17 billions planets of terrestrial type in the Milky Way. The transit method of supervision exoplanet is the most widespread, on an equal basis with a Doppler method.
In the atmosphere of an alien planet HR8799c, which distance from the Earth is approximately 130 light years, the astronomers found vapor of water and carbon monoxide. The astronomers say that in the HR8799c planet, there is no methane, which is a gas that indicates life. The astronomical measurements, which the astronomers did during their observations, are the most precise measurements, which the astronomers have ever made outside of our solar system. Astronomers have founded over 1000 planets beyond our solar system since 1990. Among them the HR8799c is the huge planet. The mass of HR8799c, is approximately seven times more that the mass of Jupiter, which is the largest planet in our solar system. It circles a star with three other planets.
The most powerful radio telescope of the world will pull back the curtain on the planet obscuring birth. During last two years, the scientists added some antennas and resolution to the Atacama Large Millimater Array (ALMA). The ALMA radio telescope will start its operation in the next week. Last year the AlMA measured the orbits, which moves around the star, and found that the orbits has less dimensions, than the scientists thought. There is two methods for telescopes to find a new exoplanets: one- the gravitational wobble, second- changes of brightness during the passing directly in front of its star. ALMA radio telescope will announce the converting of cold gas into clouds in the protostars. The secret of 1,3 billion facility’s solution are height and distance. Facilities of ALMA sit on a 5000 meter high above the sea. The astronomers, working in ALMA facility at 2900 meters, will use oxygen. The ALMA system include approximately 50 antennas. The system of operating is following: the antennas snag an astronomical signals from the sky, combine all the results in the computer, for getting final information regarding the place, form where they snag the signal.This system allows ALMA not only to observe the young planets, but also pin down life – building block in gas clouds.
Astronomers discovered a little exoplanet, which has less dimensions and weight, than the smallest planet Mercury in the solar system. The planet Kepler 37b moves around the star in Lira constellation every 13 days. It has 210 light years distance from the Earth. This planet is stone planet, and has approximately 427 Celsius temperature, because of that fact, there cannot go any speech about life.The moon-size Kepler 37b is so close to its parent star, at just 0.10 AU, that it likely has no atmosphere or liquid water on its surface.Kepler 37b was discovered by telescope “Kepler”. The $600 million Kepler mission launched in March 2009, and has found more than 2,740 candidate alien worlds so far.
Scientists published habitable exoplanets catalog to list all the known planets in the galaxy that could potentially be habitable to life. The count is at seven so far, with many more to come, researchers said. When it was first released last year, it had two potential habitable planets. According to lead researcher Abel Mendez director of the University of Puerto Rico the team expected to add maybe one or two more in the catalog’s first year. The addition of five suspected new planets was wholly beyond anyone’s expectations. Mendez also said scientists are getting smarter about finding exoplanets, and the pace of discovery is increasing. The team expects to add new models in the coming year, which will affect the measurements on objects already in the catalog.
Astronomer Philippe Delorme from the Institute of Planetology and Astrophysics of Grenoble in France and his team discovered a potential rogue alien planet CFBDSIR2149 using the Canada-France-Hawaii Telescope, wandering alone just 100 light-years from Earth, suggesting that such starless worlds may be extremely common across the galaxy.The free-floating object, called CFBDSIR2149, is likely a gas giant planet four to seven times more massive than Jupiter, scientists say in a new study unveiled today (Nov. 14). The planet cruises unbound through space relatively close to Earth (in astronomical terms; the Milky Way galaxy is 100,000 light-years wide), perhaps after being booted from its own solar system.
