So today we will introduce you top 10 fact about Google that you may not know.
An exoplanet or extrasolar planet is a planet outside our solar system that orbits a star. This is a list of habitable exoplanets and possible exoplanets. We are introducing you top 10 potentially habitable exoplanets, that is based on estimates of habitability by the habitable exoplanets catalog (HEC), and data from the NASA Exoplanet Archive. The HEC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo.View More Top 10 Potentially Habitable Exoplanets
K2-229b is an exoplanet, which is very hot and metallic. The exoplanet’s density is similar to Mercury. An Earth-sized planet is located 339 million light years away. A global team of astronomers including the University of Warwick discovered the exoplanet.View More K2-229b Is a Newly Discovered Exoplanet approximately with Its Size of Earth
Today our report is dedicated exoplanets, it seems that we have some interesting news for you. Let’s find out together.
Astronomers reported that they discovered 15 new exoplanets in our solar system. The new exoplanets were found orbiting small and cool stars. It is also called red dwarf stars. Among these exoplanets, 3 were discovered to be super-Earths, which are to some extent bigger in size than our Home planet.
One of the new discovered exoplanets are called K-155 and it is around 200 light years away from Earth and is considered the brightest red dwarf stars. K2-155’s system includes three super-Earths, the super-Earth orbiting the furthest away from the star could be within its habitable zone. K2-155d had a radius that is 1.6 times larger than that of Earth. Teruyuki Hirano, the lead researcher of the new study, from the Tokyo Institute of Technology, said “In our simulations, the atmosphere and the composition of the planet were assumed to be Earth-like, and there’s no guarantee that this is the case.”
NASA’s exoplanet-hunting space telescope has arrived two months ahead of its planned launch. The Transiting Exoplanet Survey Satellite (TESS) was delivered via truck to NASA’s Kennedy Space Center (KSC) on Monday (Feb. 12), agency officials said. The spacecraft made the journey from the Dulles, Virginia, facilities of the aerospace company Orbital ATK, which had spent the last year building and testing TESS. TESS is scheduled to lift off atop a Space X Falcon 9 rocket no earlier than April 16 from Cape Canaveral Air Force Station, which is next door to KSC.View More NASA’s exoplanet-hunting space telescope has arrived two months ahead of its planned launch
NASA reveals Sunflower-shaped spacecraft which will help to find alien planets. Scientists believe that with the use of this technology, researchers could take direct images of other planets with alien life.
The Sunflower-shaped spacecraft is also unique in that, unlike most space-based instruments, it’s one part of a two-spacecraft observation system. “We can use a pre-existing space telescope to take the pictures,” explains astronomers. The Sunflower-shaped spacecraft will allow it to move around in order to block the light from different stars. NASA’s engineers are optimistic that refining their technology could be the key to major exoplanet discoveries in the future.
For the first time from the moment of opening of the first extra solar planets scientists could see such planet by supervision in the x-ray range with help of Chandra space telescope and the European XMM Newton. The majority known exoplanets (which number at present exceeds 900) opened with help of a so-called transit method — by fixing of small fluctuations of brightness of stars when passing planet against a star disk. Still supervision was conducted only in the optical range, but now scientists managed to see x-ray transit. Thousand candidate exoplanets were found thanks to transits in visible light. At last, the scientists could see one in a X-ray, which is important as gives new information on properties of exoplanets.View More Chandra space telescope pictured exoplanets in a X-ray
The first results of the analysis of eight hot planets showed that the structure of the atmospheres of these exoplanets is more difficult, than was considered earlier. Catharine Hitson from University of Exeter, England, delivered the report on carrying out this research on the National astronomical assembly which was taking place in Saint Andrews, Scotland, on July 5. Hot planets represent huge exoplanets the size approximately about Jupiter. The exoplanets address in such short distance to the stars that the atmospheres of these planets are warmed to 1000-3000 degrees Celsius. Astronomers can find what gases are present at the atmospheres of hot planets, analyzing a range of the star light which has passed through the atmosphere of a planet when a planet is directly before a disk of the star.View More New studies about exoplanets atmosphere structure
Published the new research, allowing to calculate influence of clouds on climate of alien planets, rotating round red dwarfs. Conclusions of participants of the joint group of the Chicago and Northwest universities are based on exact computer modeling of behavior of clouds in the atmosphere of alien planets. But besides purely scientific interest, this research also allows to draw a conclusion that existence of a cloudy cover twice expands a manned space of red dwarfs. And it means that only in one galaxy in a manned zone of the stars there can be over 60 billion alien planets. The formula for calculation of a manned space of alien planets is places where they can keep liquid water on the surface. But it is insufficiently exact as almost doesn’t consider existence of clouds in the atmosphere of exoplanet.View More 60 billion alien planets in a manned space of red dwarfs
The American scientists analyzed the data collected by a Kepler space telescope in scattered cluster of stars on a joint of constellations of the Swan and Lira. In one of them the scientists found two small impossible planets. Earlier the existence of these plants was considered as the impossible. Soren Meibom (from the Harvard-Smithsonian center of astrophysics in Cambridge) and his colleagues analyzed the data collected by a Kepler space telescope at supervision over cluster of stars in constellations of the Swan and Lira. In total scientists tracked fluctuations in brightness of 377 stars. In the scattered congestion NGC 6811 in Swan constellation which is removed from on 3 thousand light years, they found two impossible planets which brightness periodically went down. Scientists tracked its changes and came to a conclusion that blinking of these stars arose because on their disk passed rather small giant planets of Kepler-66b and Kepler-67b, whose radius were more than terrestrial everything by 2,8-2,9 times.View More Kepler space telescope discovered impossible planets in a cluster of stars
