Astronomers Discovered Seventeen New Extra solar Planets: Using data collected by NASA’s Kepler space telescope, astronomers discovered seventeen new extrasolar planets. Using data collected by NASA’s Kepler space telescope, a team of astronomers in Canada discovered 17 new exoplanets.
And including an Earth-sized globe. Named KIC 7340288b, the planet is rocky and is in the habitable zone of its mother star. The sizes of 17 new planet candidates compared to Mars, Earth and Neptune. The green planet is KIC 7340288b. “KIC 7340288B is about 1,000 light years away, so we will never get there,” said Michelle Kunimoto, Ph.D. Candidate at the University of British Columbia.
But this is a really exciting discovery, since there are only 15 small and confirmed planets in the habitable zone found in Kepler’s data. This planet is only 1.6 times larger than Earth. It orbits its host star once every 142.5 days at a distance of 0.444 AU (larger than the orbit of Mercury in the solar system) and receives approximately one third of the light that Earth receives from the Sun.
The smallest of the other 16 new planets discovered is only two-thirds the size of the Earth, and Kepler is one of the smallest planets ever found. The rest of the range is up to 8 times the size of the Earth. In the study, Kunimoto and his colleagues presented the NRC Herzberg Astronomy and Astrophysics and Dr. Jaymie Matthews of the British Columbia professor.
Henry Ngo used the transit method to see planets among the approximately 200,000 stars observed by the Kepler mission. “Every time a planet passes in front of a star, it blocks a part of that star’s light and causes a temporary decrease in the brightness of the star,” he said.
By finding these dives known as transits, you can find information about the planet, such as its size and how long it orbits it. The astronomers also used the near infrared spectrometer (NIRI) imager and spectrometer in the Gemini North 8-Me telescope in Hawaii to capture tracking images of some stars that host planets. “We took images of stars from space, such as the use of adaptive optics,” Kunimoto said.
We can determine if there was a star nearby that could affect Kepler’s measurements, such as the cause of the sinking. In addition to the new planets, the team was able to observe thousands of known Kepler planets using the transit method, and the census of the exoplanet as a whole would be re-analyzed.
We must estimate how many planets are expected for stars with different temperatures,” Professor Matthews said. “A particularly important result would be a planetary incidence rate of the habitable zone on Earth. How many planets are there like Earth?
215th meeting of the American Astronomical Society: The 215th meeting of the American Astronomical Society (AAS) was held in Washington, DC from January 3 to 7, 2010. It is one of the largest astronomy meetings in history, since 3,500 Astronomers and researchers expected him to attend and present more than 2,200 scientific presentations.
The meeting was billed as “the largest astronomy meeting in the universe”. A series of discoveries were announced with new ideas of the universe in which we live; Like calm planets like Earth, where life can evolve, they occur in abundance, despite the fact that there are cosmic obstacles, such as those experienced by our own planet in the past.
The Wide Field Infrared Reconnaissance Explorer (WISE) is on a NASA mission, which uses infrared light to scan the entire sky for millions of hidden objects, including asteroids, failed stars, and powerful galaxies. Released on December 14, 2009, the WISE data will serve as a navigation tool for other research on space missions such as the NASA Hubble Telescope and the Spitzer Space Telescope.
The first image was presented at the 215th annual AAS meeting. An infrared snapshot was taken of an area in the Carina constellation near the Milky Way galaxy immediately after the reconnaissance telescope. On a patch of sky three times larger than the moon, the image shows about 3,000 stars in the Carina constellation.
The creation of planets around massive stars: The focus of the discovery of new exoplanets has been on stars like the sun. A list of over 400 exoplanets has shown these discoveries to be successful, as exoplanets of different sizes have been discovered. However, other types of stars are also a potential location for the discovery of new exoplanets.
New research, announced at the meeting, confirms that planet formation is a natural by-product of star formation. The planet also forms around stars on a much larger scale than the Sun. However, the life of stars orbiting planets is so short that intelligent supernatural life is unlikely.
Type A and B stars were examined for research, including NASA’s Spitzer Space Telescope, the two-micron all-sky study, and the Harvard-Smithsonian Center for Astrophysics (CFA) and the National Observatory for Optical Astronomy (NOAO). The team article was published in the Astronomical Journal.
