| Found, Mysterious Object Near Star Like the Sun Posted: 10 Dec 2009 07:46 AM PST
 Astronomers claim to work directly photographing objects like planets orbiting a star like our sun. A similar discovery was announced last year when astronomers gets photos directly from the solar system and have single planet. But differs from these latest findings, which became the center star in the system of the previous findings are giant stars are much larger than the Sun.The image of the new object was taken in May and early August in the testing tool on the planet hunter's Subaru telescope located in Hawaii. Objects called GJ 758 B is orbiting a parent star mass and temperature comparable to our sun. So says research team member Michael McElwain of the University of Princeton. The star is 480 trillion km, or about 50 light years from Earth. Scientists are not sure whether the object was a large planet or a brown dwarf (brown dwarfs), or also known as a failed star. The mass of the object was estimated to 10-40 times Jupiter. Objects that have mass above 13 times Jupiter (and still below the mass necessary to trigger a nuclear reaction on a star) is considered as brown dwarfs. After all, McElwain admitted that the pictures were quite interesting. "Brown dwarf star like our sun with extremely rare. Interesting discovery was something so cold and so low mass near that of a star similar to our solar system." Similar object distance from the star the planet is at least 29 times the distance of Earth to the Sun, or roughly the distance between the Sun to Neptune. by McElwain, the fact that there is such a large object orbiting in the region raises the question of traditional thinking about how to create planets. Astronomers believe that most of the major planets formed at distances closer or farther from the star, but not at a distance where the GJ 758 B is now located. "The discovery is challenging but beautiful on a very low-mass objects near a star like our sun once again reminded how limited our knowledge of the large gas planets and brown dwarf stars that are close," said Alan Boss, an astronomer at the Carnegie Institution of Science, Washington DC, who are interested though not involved in the study. "This discovery enables thinkers to begin to understand how collection agencies in this space, which was not visible and can be formed and evolved." Equipment installed on Subaru telescope, the so-called high-contrast imaging Koronagrafik with Adaptive Optics, is part of a new generation of tailor made equipment to detect faint objects near bright stars by reducing glare that. According to scientists, imaging of the telescope to find objects that might be the second best in the stars, which started to be called GJ 758 C. However, still need further observations to confirm this second object was near or just seem so. The research team consists of scientists from Princeton, the University of Hawaii, University of Toronto, Max Planck Institute for Astronomy in Heidelberg (Germany), and the National Astronomical Observation Center in Tokyo. His study was published online on November 18 in the electronic version of the journal Atrophysical Journal Letters.   |
| The Hubble Space Telescope Reveal Old Galaxies Posted: 10 Dec 2009 07:40 AM PST
 Hubble space telescope has discovered some of the oldest galaxies are so far not been known. The galaxies are detected by the Wide Field Camera, Wide Field Camera 3, the new telescope was installed on the last repair mission. According to scientists, these galaxies formed 600 million years after the Big Bang. The scientists believe that the big explosion that created the universe. Intargalaxy distance is estimated at 13 billion light years (each year light approximately 9.65 trillion km).This image taken from the area of space called the Ultra Deep Field and has been scanned by the Hubble in 2004. New camera is equipped with a channel near infra-red so that the orbiting telescope that could see further into space and record a further object. "We can now see farther into the past, identify the galaxy when the universe is only five percent of the current age," said Daniel Stark, a researcher from the Institute of Astronomy in Cambridge who are involved in such research. The new cameras installed in May by NASA astronauts as part of a mission to upgrade and repair the telescope, which has 19-year-old. Two teams from the University of Oxford and the University of Edinburgh will report these findings in the publication Monthly Notices of the Royal Astronomical Society.   |
| 11 Vegetables That Are The Cancer Killer Posted: 10 Dec 2009 07:32 AM PST
 Chairman of the Cancer Information and Support Center (CISC) Semarang Cahyaning Puji Astuti said, at least there are about 11 types of vegetables are proven effective to prevent cancer. "Fruits and vegetables are actually much more powerful than vitamins, but not all vegetables and fruits are anticancer," he said after a seminar on "Preparing Healthy Foods Preventing Cancer" in Telogorejo Hospital, Semarang, Thursday (10/12/2009).Naning mention, 11 vegetables, cancer prevention, including cabbage, garlic, onions, soy, turmeric, green tea, tomatoes, oranges, chocolate, fruits and berries, like blueberries and strawberries. However, although some vegetables and fruits were efficacious as anticancer, awareness and understanding necessary substances contained in vegetables, including notice processing process. According to him, cabbage is the main enemy of cancer, either green cabbage, white cabbage, broccoli, cauliflower, watercress, cabbage and purple. In fact, the efficacy of cabbage has been known since the time of Hippocrates around 460-377 BC. "Hippocrates said, cabbage is a vegetable with thousands of properties, and consume at least five servings of cabbage per week proved to be minimize the risk of esophageal cancer and slow the progression of cancer," he said. However, cabbage processing still must be considered so as not remove the advantage, of which not cook it too long, but still must be clean, and chew carefully. Garlic and onions are also very effective for preventing cancer, especially gastrointestinal cancer, esophagus, stomach, colon, prostate, lung, and breast cancer. "Cancer-preventing foods are found in soybeans, which many processed into tofu, tempeh, and milk. Because soy contains isoflavones which are anticancer compounds that have chemical structures similar to sex hormones," he said. Related to the chemical structure of isoflavones similarity with sex hormones, he warned, excessive consumption of soy is not recommended for patients with breast cancer and prostate cancer. "The cancer is a type of cancer is highly dependent on the hormone, a hormone estrogen to breast cancer and hormone androgen for prostate cancer," said Naning is also suffering from cancer. In addition, he said, a prescription to avoid the risk of cancer can be done by avoiding certain foods, eg, pickled food, smoked foods, and fried foods. "Regular exercise, stop smoking, and avoiding consumption of red meat is also an application of healthy lifestyles that need to be applied to prevent cancer," said Naning.   |
| Armagedon 2012 Is Just "Pseudosience" Posted: 10 Dec 2009 07:27 AM PST
 Society does not need to bait the issue of end 2012. Because, based on scientific studies, this issue has no basis in science. Natural phenomena that might occur in that year was the storm the sun. "The issue of end 2012 is pseudoscience (do not follow the scientific method). There is a connection with the appearance of Nibiru Planet, there is also a large comet, which astronomers do not actually exist," said Thomas Djamaluddin, professor of astronomy, astrophysicist from the Institute of Aviation and Space Agency (Lapan ) in the event Press Tour, Thursday (10/12).Furthermore, he explained, the only possibility of natural disasters due to space conditions in the year 2012 was the storm that triggered space solar storms. "But, we did not have to worry about, too. Not necessarily the storm was going to lead directly to Earth. Because, the Earth's spinning," he said. Head of Science Center for Space Utilization Lapan, Sri Kaloka, who was present to explain to reporters that the issues set out in the end the myth of 2012 prediction Maya calendar. However, he confirmed the possibility of a large solar storms in that year. Solar activity peak in the cycle is now 24 was originally estimated to occur in 2012. But, then moved in 2013 because the sun activities is still minimum. "But, because it is linked to the statistics, is still a debate," he said. He explained, peak solar cycle is marked by the number of black spots on the surface of the sun can trigger the appearance of tongues of fire (corona mass ejection) that carries the particles high berenrgi. If you came to earth, these particles can disturb magnetosphere to the ionosphere on Earth. The impact can damage satellites, tool, Telecommunication and electricity on Earth. Hurl billions of tons of particles can also affect the pattern of magnetic fields on Earth. "There's a paper in Germany who say that the pigeons disturbed because they have related navigation in the Earth's magnetic field," he explained. Concrete cases under the influence of solar storms occurred in 2003. At that time, many satellites are out of touch and does not work. "When it Lapan also noted the decline in telecommunications functions in the ground water. High radio wave was broken," said Thomas later. Head of The Sun and Space Lapan Yatini Clara Yono added, a unique activity on the sun often becomes an attractive material for science fiction film. As an example of the material from the solar neutrinos in the 2012 film became a source of peril. "It's ordinary neutrinos come from the sun, not necessarily when a storm. Not like in the movies, the material is not charged and was not arrested in mass and this land should not until boiling magma on the Yellow Stone," he said.   |
